0:02 [ beeping ]
0:08 >> Stand by for terminal count.
0:13 [ indistinct radio chatter ]
0:26 >> It's morning of launch,
0:27 almost 3:30.
0:29 And we're going to make
0:30 our fueling
0:32 go-or-no-go call soon.
0:33 >> Okay. Take it away, Robert.
0:36 It's all yours.
0:38 >> Merry Christmas
0:39 from the Guiana Space Center,
0:41 where the fueling of the vehicle
0:42 is moments away,
0:44 while weather systems
0:45 are being carefully monitored
0:47 for the momentous launch
0:48 of the largest,
0:49 most powerful telescope
0:50 ever sent away from our planet.
0:56 >> It is the product of a feat
0:58 of human ingenuity.
1:00 >> 14 countries
1:01 all working together.
1:03 >> We want to look back
1:05 and see some of the very first
1:06 stars and galaxies
1:07 that were born
1:08 in the early universe.
1:09 >> What we call cosmic dawn.
1:12 >> We have to accept the fact
1:13 that we are in a risky business.
1:15 >> Powerful storms hit the...
1:16 >> Everybody said,
1:17 if James Webb is unsuccessful,
1:19 then NASA will never take on
1:21 a big challenge again.
1:24 [ music ]
1:52 >> Now there's
1:53 a little pond down here.
1:54 >> Yeah.
1:54 >> Which there still is.
1:55 And used to come fishing
1:58 here occasionally.
1:59 >> Well, I would like
2:00 to tell you the entire story
2:02 of the universe
2:02 and a bit about
2:03 how we learned about it
2:04 and my personal part
2:05 of this process
2:06 and-and where
2:08 we're going from here.
2:09 And the title slide here says,
2:11 "from the Big Bang..."
2:12 and on, et cetera,
2:13 "to the Discovery
2:13 of Alien Life."
2:14 And so we haven't
2:16 exactly found it yet,
2:17 but I think it's possible
2:18 in the next few decades.
2:19 And so I want to
2:20 outline at the very end
2:21 how we are hoping
2:22 to find out about that.
2:23 So there are many,
2:24 many mysteries.
2:25 I got interested
2:26 in math and science
2:27 when I was a little kid.
2:29 Here is a picture of the place
2:30 where I grew up.
2:31 My dad was a scientist,
2:32 but he studied dairy cows.
2:34 I heard from him
2:35 that people were made
2:36 out of cells with chromosomes.
2:38 I can remember
2:39 I was about six years old
2:40 and I had heard about infinity.
2:50 Oh, well, that's
2:51 pretty fascinating.
2:51 So, okay,
2:52 I want to know
2:54 more about this.
2:57 By eight years old,
2:58 I was reading Galileo
3:00 and Darwin biographies
3:01 and getting all the books
3:02 about science I could get
3:03 from the public library.
3:08 I latched on pretty early.
3:10 I knew when I got
3:11 into the mission
3:12 that it was going
3:12 to be exciting.
3:13 I said, this is
3:14 the coolest thing
3:15 I've ever heard of.
3:15 This is what I want to work on,
3:17 and I do not care
3:18 how hard it is
3:19 or how long it's going to take.
3:20 I just want to work on it
3:21 and make it happen.
3:35 I love the feeling of awe.
3:37 >> But then sharing
3:38 that excitement with someone
3:40 is then the next best
3:42 feeling in the world.
3:43 >> It's-it's super close,
3:44 but this one.
3:45 >> Of these two?
3:48 One of the things
3:49 growing up in the city
3:50 that we didn't really ever see
3:52 was the sky.
3:53 I do remember
3:54 sort of one of these, like,
3:55 core childhood memories
3:56 is going up to Canada
3:57 on a family vacation,
3:58 and my parents
4:00 ushering me outside one night
4:02 to look at the Milky Way.
4:04 And I didn't understand
4:05 what it was.
4:06 And I was like,
4:07 there's milk up there?
4:08 They're like, no, no, no.
4:09 That's our solar system.
4:11 And we're looking up at all
4:12 the stars that you wouldn't
4:13 otherwise see.
4:14 And I just--
4:15 I really didn't comprehend,
4:17 because I had
4:19 no exposure to that
4:21 prior in my life.
4:24 And here I am, years later,
4:28 following the astonishing story
4:31 of the James Webb
4:32 Space Telescope.
4:34 >> Nature has this way
4:35 of being even more creative
4:36 than we are.
4:37 So we have always been surprised
4:40 by what we see in the sky.
4:45 >> This is, uh,
4:46 a really tremendous adventure
4:48 that we've been on.
4:49 >> The first Hubble Deep Field
4:51 actually came out
4:51 when I was in high school.
4:53 I already knew
4:54 I wanted to be an astronomer,
4:55 but I remember
4:56 being just captivated
4:58 by these images that were
4:59 coming back from Hubble.
5:09 It blew my mind to see that--
5:11 that first deep field image.
5:12 And that was sort of
5:13 a, like, yup,
5:14 this is what I want to do.
5:17 >> The earliest conception
5:18 of Webb derived from the fact
5:20 that Hubble took a deep field
5:22 and didn't see
5:24 newly formed galaxies
5:26 after the birth of the universe.
5:28 >> It's sort of like
5:29 we're missing that
5:30 very first piece of the puzzle
5:32 of how galaxies
5:33 got their start.
5:35 >> Every time NASA builds
5:36 a new telescope,
5:37 it needs to be
5:38 way more sensitive
5:40 than anything
5:40 we've ever built before.
5:42 So every time
5:43 you launched something,
5:44 it was a new window
5:45 on the universe.
5:48 And so for Webb,
5:49 we needed to build something
5:51 that was 100 times
5:51 more capable.
5:53 >> The main thing that Webb
5:55 had to do to be successful
5:57 was find these
5:58 very first galaxies.
6:01 >> To look back in time
6:03 to a part of space
6:04 that we've never seen before,
6:07 and see the very first epoch
6:09 of galaxies that were born
6:10 after the Big Bang.
6:14 >> People think the Big Bang
6:15 is a mystery
6:16 because they think
6:17 it's not what it is.
6:22 The actual picture
6:22 that we have as astronomers
6:24 is the entire universe
6:26 is expanding.
6:27 The material is rushing
6:28 apart from other material
6:30 in a rather smooth,
6:31 continuous way,
6:33 while we see galaxies
6:34 rushing away from us.
6:36 So what's going
6:37 to make them rush apart?
6:38 Well, something
6:39 kicked them off that way.
6:41 But since we imagine
6:42 the universe is infinite,
6:44 it has to be
6:45 an infinitely large cause,
6:47 whatever that is.
6:48 So we just imagine
6:50 running the movie
6:51 backwards in our minds
6:52 until it's different.
6:53 So when you get farther
6:55 enough back in time,
6:56 the temperature and everything
6:58 is mushed together.
6:58 The galaxies are
6:59 mushed together.
7:00 The stars are mushed together.
7:01 The atoms are mushed together.
7:02 The atoms are torn apart
7:04 into their constituent
7:05 subatomic particles.
7:06 So that's the movie you get
7:08 if you run everything backwards.
7:09 So then when you
7:11 run out of imagine,
7:12 you say, that's the big bang.
7:13 So needless to say,
7:14 astronomers have been imagining
7:16 for a long time, what was this?
7:20 >> I'd just call it
7:21 the Expanding Universe story
7:23 In "Calvin and Hobbes,"
7:25 there was a different answer.
7:27 Calvin called it
7:28 the Horrendous Space Kablooey,
7:32 but that didn't catch.
7:33 >> I'll now I ask you
7:35 to step forward
7:36 to receive your Nobel Prizes
7:38 from the hand of His Majesty
7:40 the King.
7:41 >> And it was March of 1996
7:44 when John Mather
7:46 stopped in my office
7:47 out here at Goddard
7:49 and asked me
7:50 if I'd like to work with him
7:51 on a new telescope idea
7:53 he was thinking about.
7:54 And when John came by
7:55 and said-- this of course--
7:57 this was before
7:57 he had his Nobel Prize,
7:59 but everybody knew,
8:00 oh, if John
8:01 asks you to work with him,
8:02 You want to work with him.
8:03 So I said, sure,
8:04 that would be fun.
8:05 I figured, well, I'd do that
8:06 for a couple of years.
8:07 >> So, Doctor Smith,
8:09 what is a next generation
8:11 space telescope?
8:12 >> Well, the NGST,
8:13 or Next Generation
8:14 Space Telescope,
8:15 is the logical successor
8:17 to the Hubble Space Telescope,
8:18 or HST.
8:19 NGST is designed
8:20 to see the first stars
8:21 and galaxies
8:22 that light up in the universe.
8:24 And, well, here we are,
8:26 you know, more than
8:27 25 years later,
8:28 I'm still working on Webb.
8:31 >> Apollo 8, over.
8:32 >> Hello, Apollo 8.
8:33 Loud and clear...
8:34 >> Administrator O'Keefe
8:36 renamed the Next Generation
8:38 Space Telescope
8:39 to the James Webb
8:40 Space Telescope
8:41 in honor of James Webb,
8:42 who was the second
8:43 administrator of NASA.
8:45 So why name it after this guy?
8:47 Well, James Webb
8:48 was largely responsible
8:50 for the success
8:51 of the Apollo program.
9:13 [ indistinct radio chatter ]
9:15 >> Roger, the EVA
9:16 is progressing beautifully.
9:24 >> The Webb telescope
9:25 is kind of like my child,
9:26 because I've been working on it
9:27 since the first day
9:28 that we started.
9:30 So when I started on Webb,
9:32 my youngest son
9:33 had just been born.
9:34 Well, he's got
9:35 a master's degree,
9:36 he works at Johns Hopkins,
9:37 and he's going to be 28.
9:40 I had hair,
9:41 I didn't need hearing aids
9:43 or glasses.
9:44 And, yeah, it's a long--
9:46 it's a long time.
9:47 But-but in hindsight,
9:48 it's also a short time.
9:50 We had the singular purpose
9:51 for 25 years
9:52 to make the James Webb
9:54 Space Telescope a reality.
9:56 And you know, people did think
9:57 we were nuts at first,
9:58 because the technical
9:59 challenges
10:00 were so daunting,
10:01 and the number of things
10:02 we had to advance
10:04 or literally invent
10:05 were numerous.
10:07 >> I remember we had a draftsman
10:09 who was able to draw
10:10 what we said on a whiteboard,
10:11 and we said we needed
10:12 a big telescope
10:13 with a big baffle,
10:16 a big umbrella to protect it
10:17 from the heat of the Sun.
10:18 So he drew this
10:19 on the whiteboard
10:20 and we all said,
10:20 yeah, that looks pretty good.
10:21 We need something like that.
10:22 And it's going
10:23 to have to fold up.
10:24 And we started talking
10:25 about how it folded up,
10:25 and that was just the beginning.
10:27 And we knew we were
10:27 on to something.
10:29 >> In the early parts
10:30 of the mission,
10:31 we talked to the scientists
10:31 and we find out,
10:32 what's the scientific
10:33 objectives of this mission?
10:35 What do you want it to do?
10:36 Right? Then we put that
10:37 into a language
10:38 that engineers understand
10:39 called requirements.
10:40 How big does it have to be?
10:42 What kind of sensitivity
10:44 do you want?
10:45 In other words,
10:45 what's the dimmest thing
10:46 you want to see?
10:47 >> The James Webb Observatory
10:48 has three parts to it.
10:49 The first part is the telescope
10:52 and the science instruments.
10:53 This has to be very, very cold.
10:55 >> It's designed to collect
10:56 infrared light.
10:57 So infrared is something
10:58 that you cannot really see
11:00 with your eyes.
11:01 The Hubble telescope
11:02 can see a little bit of it,
11:02 but it's-it's not cold.
11:04 So the Hubble telescope glows
11:06 and emits infrared light itself.
11:08 So you cannot use it
11:09 to do all of the things
11:10 that astronomers
11:11 have identified
11:12 as their next top priority.
11:13 This telescope is going to be
11:14 in outer space.
11:15 It's going to be cooled
11:15 to a very low temperature
11:16 of 45 degrees
11:17 above absolute zero,
11:19 so that it does not glow.
11:21 >> There's one instrument
11:22 in there called the MIRI
11:23 that wants to be about
11:25 seven degrees Kelvin.
11:26 And to put that in perspective,
11:28 dry ice, carbon dioxide,
11:29 dry ice is at about
11:31 -109 degrees Fahrenheit.
11:34 The second part
11:35 is the spacecraft bus.
11:37 And the spacecraft bus operates
11:39 at room temperature up here
11:40 at 70 degrees Fahrenheit.
11:41 And it has the usual subsystems
11:44 the communication subsystem,
11:45 the computer, the thrusters,
11:47 the electrical power system.
11:49 Then between the two
11:51 is the third part,
11:53 the sunshield,
11:55 five thin layers
11:57 about the size
11:59 of a tennis court
12:00 that separate the hot side
12:03 from the cold side,
12:05 five little layers
12:07 that keep this thing
12:08 in the shadows.
12:10 And this umbrella,
12:11 as we might call it,
12:13 is no ordinary umbrella.
12:14 On the hot side,
12:16 200,000 watts
12:19 of solar radiation strikes it,
12:21 and it can only allow
12:22 .02 watts to get through.
12:25 This umbrella is setting up
12:27 an almost 600 degree Fahrenheit
12:29 difference,
12:30 and if it were suntan lotion,
12:32 it would have an SPF
12:34 of 10 million.
12:35 >> And it's going to
12:36 have to fold up.
12:37 And we started talking
12:38 about how to fold it up.
12:38 And it's got to be bigger
12:39 than the Hubble telescope,
12:41 and it's got to get
12:42 way out there,
12:42 and we can't get it there
12:44 without a pretty big rocket.
12:45 So what's the biggest one
12:46 you can get?
12:47 Well, it's not all that big.
12:48 We're going to
12:48 have to make a telescope
12:49 that's much bigger
12:50 than the Hubble
12:51 and simultaneously
12:52 much lighter.
12:53 We ended up at half the mass
12:54 and seven times
12:55 the collecting area.
12:56 >> All 13,670 pounds.
13:00 All six metric tons of this
13:03 has to be launched
13:04 a million miles
13:05 out in outer space,
13:06 and it has to fit
13:07 into a fairing
13:09 that's only about
13:09 five meters in diameter
13:11 when the size of the sunshield
13:13 is 21 meters in diameter.
13:14 So to do that,
13:15 we have to fold it up
13:17 like origami
13:18 so that it fits into here.
13:19 >> Pretty soon we know
13:20 our job is pretty hard.
13:21 Okay, going to have
13:22 lots of inventions
13:23 along the way.
13:24 So we made up a list
13:25 of ten inventions
13:26 that we had to have
13:27 pretty quickly.
13:28 And we said, okay, world,
13:29 tell us how you can
13:30 make these inventions.
13:31 >> You have to keep in mind
13:33 a lot of the technologies
13:34 for Webb were
13:35 new technologies, right?
13:36 So you have a plan on
13:38 how you are going to do it.
13:38 And when you are testing it,
13:40 lots of times
13:41 something doesn't work.
13:42 You have a schedule,
13:43 a certain amount of time
13:45 and a certain amount of money.
13:46 >> Basically people, although
13:47 they don't quite say so,
13:48 they think your telescope
13:49 looks weird.
13:50 So...
13:51 our-our telescope
13:53 does look different
13:54 from every other telescope
13:54 you've ever seen.
13:55 It doesn't look like
13:56 Galileo's little tube
13:57 with a lens at each end,
13:58 way different from anything
13:59 that we've ever built
14:00 for anywhere before.
14:04 We're building a perfectly
14:05 great telescope on the ground.
14:07 We're aligning on the ground,
14:08 we're testing on the ground.
14:09 It's going to work
14:09 perfectly, right.
14:10 It's going to be great.
14:11 Then what do we do?
14:12 We bust it up, we fold it up.
14:14 We put it into
14:14 a launch vehicle.
14:16 Then once we get it on orbit,
14:17 and it deploys.
14:17 Now we got to realign it on
14:20 orbit remotely.
14:22 50 of the most complex
14:23 deployments ever attempted,
14:24 robotically.
14:29 ♪♪
14:33 >> The telescope looks weird,
14:34 but that's a matter
14:35 of perspective.
14:36 To me, it looks beautiful.
14:40 >> So that's your mission,
14:41 if you choose to accept it.
14:46 >> Yes, we had 344
14:47 single-point failures,
14:48 295 of which were associated
14:50 with deployment--
14:51 almost all of which
14:52 would have been
14:54 mission ending.
14:57 >> So, with Webb,
14:58 we should probably go back
14:59 to, you know, 1990,
15:00 with the launch of
15:02 the Hubble Space Telescope.
15:03 >> And liftoff
15:04 of the space shuttle Discovery
15:06 with the Hubble
15:06 Space Telescope.
15:08 Our window on the universe.
15:10 >> NASA launches
15:10 the Hubble Space Telescope,
15:11 the biggest space science
15:12 mission ever.
15:14 >> Discovery, Houston.
15:15 Performance is nominal.
15:17 >> And shortly thereafter,
15:20 it's discovered that
15:21 its vision is blurry.
15:24 >> Conclusion we've come to
15:25 from that, is that
15:26 a significant
15:27 spherical aberration
15:28 appears to be present
15:29 in the optics.
15:30 >> I was devastated
15:31 because I'd worked
15:32 my entire career on Hubble
15:33 at that point,
15:33 >> Congress had hearings.
15:35 Hubble's the butt
15:36 of late-night TV jokes,
15:38 and it becomes
15:39 a major embarrassment
15:40 and a major black eye
15:41 for the agency.
15:42 >> Although the surface
15:43 of the mirror
15:43 was perfectly smooth,
15:45 the smoothest mirror
15:46 ever made by humans on Earth,
15:48 the trouble is,
15:49 it was too flat at the edges,
15:51 about a millionth of an inch,
15:52 which is less than
15:53 the diameter of human hair.
15:55 But that was enough to cause
15:56 the tremendously blurry images
15:58 that we saw.
16:00 My neighbors, who all used
16:01 to be very, you know, happy
16:03 and congratulating me
16:04 on working Hubble.
16:05 They'd come up to me
16:05 when I'm pushing my son around
16:07 in the stroller and say,
16:08 "Boy, it must be tough
16:09 working on a national disaster."
16:19 >> We can characterize
16:20 the problem,
16:21 the spherical aberration
16:22 problem, well enough that,
16:24 uh, we can take advantage
16:25 of an insurance policy
16:26 that we haven't
16:27 talked much about.
16:28 And that is,
16:29 we started a long time ago
16:30 to plan a maintenance program,
16:32 that is, every three years,
16:33 we plan to go up
16:34 with a space shuttle,
16:35 uh, change out instruments,
16:36 change out things that broke.
16:39 >> I come to NASA in 1991
16:42 as part of the team to help fix
16:43 the Hubble Space Telescope.
16:46 I end up leading a team
16:47 that's developing
16:48 corrective optics
16:50 for the telescope.
16:52 Astronauts install
16:54 the corrective optics,
16:56 and a new, updated camera.
16:58 >> It's completely awesome
16:59 out here.
17:00 A lot of work, but, uh,
17:01 well worth it.
17:03 >> And after five EVAs,
17:05 uh, spacewalks,
17:06 the astronauts came home.
17:07 And about two weeks later,
17:08 we took off the bandages
17:10 from our eyes,
17:11 and suddenly, Hubble was fixed.
17:13 It was totally fixed.
17:14 >> The most significant
17:15 contact lens
17:17 in American history.
17:18 [ laughing ]
17:20 Over here is the picture taken
17:22 after the servicing mission.
17:24 >> And it works beautifully,
17:25 in fact, better than
17:26 original requirements.
17:28 And it's still working today.
17:29 It's one of the most powerful
17:31 instruments that science
17:32 ever created.
17:35 >> This is one of the things
17:35 about building JWST.
17:37 We didn't have that luxury
17:38 at L2, you know,
17:39 where we couldn't service it.
17:40 We knew that.
17:48 >> The L2 point is chosen
17:49 for the Webb Telescope
17:50 because it's the first place
17:51 where you can go,
17:52 where the Earth and the sun
17:53 are always
17:54 in the same direction.
17:55 And so you can put up
17:56 your one-sided umbrella
17:57 and protect your telescope,
17:58 which you want to do either
18:00 to keep the telescope cold,
18:01 like the Webb.
18:02 If you send it
18:02 another few feet farther out,
18:04 it'll eventually escape
18:05 and go away from Earth.
18:06 If you let it stay a few feet
18:08 closer in, it'll fall back
18:09 towards Earth,
18:10 and have some kind of
18:11 interesting chaotic orbit.
18:13 Anyway, we wouldn't like that.
18:14 So it's the boundary
18:15 between Earth orbit
18:16 and solar orbit,
18:17 and that's a good place.
18:18 >> We knew that this mission
18:20 was going to require
18:22 a number of test facility,
18:23 production facilities,
18:24 and test facilities
18:26 that didn't exist in the world.
18:29 >> Right from
18:30 the very beginning,
18:31 we were told to please develop
18:32 an international partnership
18:33 to construct
18:34 the Webb telescope.
18:35 >> Webb is a global effort.
18:37 NASA, ESA, CSA,
18:39 and contractors
18:40 all working together.
18:42 It was 14 countries
18:44 and more than 29 states,
18:45 all contributing to Webb.
18:49 >> You know, I always called it
18:50 "The Giggle Factor"
18:51 a little bit, like,
18:52 can we really do this?
18:53 >> This new telescope has,
18:54 I think about 64 megapixels.
18:56 >> It's not like we could
18:57 build and test things
18:58 in those early days.
18:59 So, we were living
19:00 in virtual land as far as
19:02 computer simulations,
19:03 computer modeling.
19:04 You know, we had picked
19:05 our architecture in late 2002.
19:08 And, obviously,
19:09 that's when things
19:10 got really, really busy
19:11 with trying to make
19:11 this architecture feasible.
19:14 Uh, because I would say
19:15 even at that point,
19:16 we were not quite sure
19:19 it would all work at that time.
19:20 It just seemed so far out.
19:28 >> Let's keep making progress
19:29 on the telescope,
19:30 because the more we get done,
19:32 the better the chance
19:34 this thing will keep going,
19:35 as a program.
19:39 >> I think
19:40 of the technologies,
19:42 the ones that I remember were,
19:44 uh, most challenging were,
19:46 um, developing the material
19:48 for the primary mirrors.
19:49 We had a big effort
19:51 to determine what that material
19:53 would be.
19:54 >> And it was a kind of
19:55 exotic choice.
19:57 We chose a material
19:58 called beryllium,
19:59 which is element number four
20:01 in the periodic table.
20:02 It's extremely stiff,
20:04 extremely light.
20:05 >> It was the cryogenic
20:05 properties of beryllium
20:07 that really won out.
20:08 You know, it's-it's
20:09 how stable it was at,
20:10 at cold temperatures,
20:11 and its thermal conductivity,
20:13 how thermally stable
20:14 things were.
20:16 >> When we mine the ore,
20:17 we have to drill through
20:18 and blast the rhyolite,
20:21 remove that, to get to
20:23 the volcanic ash layer
20:24 where the beryllium is.
20:28 >> 10,000 years ago,
20:29 this was the bottom
20:30 of Lake Bonneville.
20:31 And millions of years ago,
20:32 it was an ancient ocean.
20:35 >> So then it's pressed
20:36 into this 550 pound block
20:38 that's then machined out
20:40 until it's about 50 pounds.
20:41 Once that block is machined out
20:43 to about 50 pounds,
20:44 the backside is honeycombed.
20:45 It's really cool looking.
20:49 The front side gets polished.
20:50 We're attaching motors
20:51 to the back, so they can--
20:52 The mirrors can actually move
20:53 and flex up in space,
20:55 so they can align.
20:55 Then what we do
20:56 is we actually subtract
20:58 off gravity.
20:59 So we're building this
21:00 in a place that has gravity.
21:01 This telescope operates
21:03 in space.
21:03 It has no gravity.
21:04 The temperature change
21:06 that happens between Earth
21:08 and space actually deforms
21:09 the mirror significantly.
21:10 >> You literally polish,
21:12 you know, the wrong surface
21:13 into a mirror,
21:14 so that when they cool down
21:16 and they change their shape
21:17 as they cool,
21:18 it's the right surface.
21:19 >> And so, we actually make
21:20 the mirror less good
21:22 on Earth, so it can be
21:23 more perfect in space.
21:25 >> We would then send them
21:26 to Huntsville, Alabama,
21:29 where we would test them
21:30 at Marshall,
21:31 and we would cool them down
21:33 to these very cold temperatures
21:34 and measure with
21:35 a special test device
21:37 how they change
21:37 as they cool down.
21:40 >> Let's talk a little bit
21:41 about those
21:42 18 iconic gold mirrors
21:44 that are actually
21:45 on this telescope.
21:48 Amber, can you tell us
21:49 about the science
21:50 behind those mirrors?
21:52 >> So, the reason
21:53 the mirrors are gold
21:54 in the first place is because
21:55 gold is a good reflector
21:56 of infrared light.
21:57 So we've already talked about
21:58 how Webb will view
21:59 the universe in the infrared
22:00 part of the spectrum.
22:02 And that means it will see
22:03 light that's just a little bit
22:04 more red than visible light,
22:06 than what your eyes can see.
22:08 And so it turns out
22:09 that gold reflects
22:10 that type of light really well.
22:12 So that's sort of
22:12 the science behind
22:13 why the mirror is gold.
22:17 >> So these are things
22:18 that people don't realize
22:19 it takes to, uh,
22:20 to get a telescope
22:21 like the Webb telescope built.
22:27 >> But every week that went by,
22:30 you know, we started
22:31 getting questions like,
22:32 why is this taking so long?
22:33 And is this is going to go on
22:33 for-- you know, and there was
22:34 a lot of pressure.
22:36 >> Okay. The Committee on
22:37 Science, Space and Technology
22:39 will come to order.
22:39 The James Webb Space Telescope
22:42 has been identified by
22:43 the astrophysics community
22:45 as its top priority.
22:46 >> There were voices out there.
22:47 There was talk of,
22:48 oh, let's cancel this thing.
22:50 It was always a concern
22:52 of mine personally,
22:54 from long before,
22:56 we could end up like
22:57 the Superconducting
22:58 Super Collider, right?
23:00 Don't want Webb
23:01 to end up like that.
23:02 You know, a really large
23:03 science project ended up being
23:05 too much and too long,
23:07 and people lost the stomach
23:09 to, um, see it through.
23:11 >> Thank you for the question.
23:14 >> Congress got
23:15 really worried about
23:16 our Webb telescope and said,
23:17 isn't that kind of crazy
23:18 not to be able to service it?
23:20 And the answer is, yeah,
23:21 that's the only choice we had.
23:22 >> The James Webb
23:23 Space Telescope
23:24 is another case study
23:26 of NASA's mismanagement.
23:27 >> Now, how can we justify--
23:29 [ overlapped conversations ]
23:33 >> I hope that we don't
23:34 lose sight
23:36 of why the United States
23:37 is undertaking
23:38 this complex mission
23:40 in the first place.
23:41 >> If James Webb is
23:42 fully funded, NASA will be
23:44 on track to launch the largest
23:45 and most powerful
23:46 space observatory ever built.
23:49 >> The average person
23:50 would be like,
23:50 I couldn't, you know,
23:53 bear the pressure
23:54 and the anxiety and stuff,
23:56 and well,
23:58 what's the secret?
23:59 >> Yeah, how do you handle
24:00 the pressure
24:01 of something like this
24:01 is an amazing question.
24:03 I will say the bonds
24:04 that we built through failure
24:07 and then through success,
24:08 of course, it was a family.
24:11 We argued.
24:13 >> The position as the MOM,
24:14 Mission Operations Manager,
24:15 and, you know, it was--
24:20 the job is kind of
24:21 sometimes like being the mom
24:22 for everybody.
24:23 So, everybody in here,
24:27 you know, I almost, you know,
24:28 you get to the point
24:29 where you almost personally
24:30 putting them into the positions,
24:31 and you're- you're kind of
24:32 helping them grow into
24:33 what's going to happen.
24:34 You try to prepare them.
24:35 Um, you know, because
24:36 I would tell people
24:37 that it's-it's, um,
24:40 it was a very stressful job
24:41 as we got closer.
24:47 And you had to kind of work
24:48 with people to help them
24:50 deal with the stress
24:51 and stuff like that.
24:52 So it was, you know,
24:53 you tend to be a mom,
24:54 be a good friend.
24:55 And we all knew the risks.
24:58 >> You know, we all knew
24:59 this wasn't a sure thing.
25:00 None of us left.
25:01 That's what I'm proud of.
25:02 [bicycle bell ringing]
25:05 >> First and foremost,
25:07 we were ourselves
25:08 and we brought our strengths.
25:09 And we brought our-
25:10 our colorful parts
25:11 of ourselves.
25:15 The way we survived.
25:17 Ultimately, though,
25:18 if I could attribute it
25:19 to one thing, is,
25:20 the more the naysayers
25:22 came at us, the more we
25:25 as a team bound together.
25:27 If the naysayers thought
25:28 they were going to cancel
25:29 this program
25:30 by what they did,
25:31 they only made us stronger.
25:33 >> In the early times,
25:34 up until now, practically,
25:37 the budget was not
25:37 what the project
25:38 actually required.
25:39 The budget was what people
25:40 could get for us.
25:41 And so, it didn't change
25:42 until Senator Mikulski
25:43 wrote a letter and said,
25:45 we're tired of hearing
25:46 from you guys, uh,
25:47 when are you going to tell us
25:48 the real number?
25:49 She didn't say it in
25:50 those words exactly, but...
25:52 please stop embarrassing us.
25:54 So what's the real number?
25:55 >> Two... One.
25:58 [ cheers and applause ]
26:01 Senator.
26:04 >> Good morning, Goddard!
26:06 How are we today?
26:07 [ cheers and applause ]
26:10 I am so happy to be here
26:12 with you in the new year.
26:14 [ cheers and applause ]
26:16 >> What led to us persisting
26:18 were people like
26:18 Senator Mikulski,
26:20 who was a huge advocate
26:22 for Webb
26:23 and for NASA Goddard,
26:24 and for science, in general.
26:26 The science community
26:27 was largely,
26:29 solidly, behind Webb
26:30 because they knew
26:32 the potential this thing had.
26:34 And how important it was.
26:36 >> When we go into space,
26:38 we don't go to conquer.
26:40 We go to discover.
26:42 To discover new things
26:44 about the universe.
26:50 >> We finish assembling it
26:51 and ship it off to NASA.
26:54 [ bell ringing ]
27:04 >> We really don't know
27:05 much about it.
27:06 We know that it was 18 pieces.
27:09 We have pictures
27:10 of what it was like.
27:13 [ music ]
27:17 And, uh, that's about it.
27:19 Everything else
27:19 is sort of secretive.
27:21 We just take it
27:21 from point A to point B.
27:24 Each mirror's worth about 20,
27:26 and we have three
27:27 in the trailer,
27:27 so that's $60 million.
27:29 And, if we drove the truck
27:32 thinking constantly
27:33 that there was $60 million
27:34 in the trailer,
27:35 we'd probably just
27:36 drive ourselves crazy
27:38 and nervous wreck up here.
27:39 We just have to treat it
27:40 like everything else
27:41 and drive it and do our job.
27:43 Bye, guys!
27:49 That new space,
27:50 uh, mirror thing
27:51 that we're carryin'
27:52 in the trailer,
27:52 is going to be a little over
27:54 a million miles away,
27:56 and we've driven 1,000,003
27:58 on the last truck,
27:59 so it's going to be really far,
28:02 I can tell you.
28:04 You know, because
28:04 a million miles is a long time
28:06 behind the wheel of a truck.
28:07 So, I can tell you a million miles
28:09 far away is a long distance.
28:11 It's real, I've seen it.
28:13 I've seen crates
28:15 that the mirrors go in.
28:17 I've seen the drawing
28:18 of what the mirrors
28:18 are gonna look like
28:19 once it's put together.
28:21 You've got 18 of them
28:22 all hooked together.
28:23 So then you have to imagine
28:24 that they're folding
28:25 each one of these up,
28:26 and then they're opening all up
28:28 at the same time.
28:29 It's just like a flower.
28:30 It's going to be beautiful.
28:32 >> I have a little,
28:33 a little trouble sleeping
28:34 knowing that these mirrors
28:35 are on a truck,
28:36 crossing the country.
28:39 These are the final three
28:41 mirror segments for
28:42 the James Webb Space Telescope.
28:44 So yeah, an incredible
28:45 milestone here today.
28:47 Exciting.
28:49 >> We're getting up early.
28:51 >> Absolutely worth
28:52 getting up early
28:53 and standing here in the cold.
28:54 Sure.
28:56 These mirrors will literally
28:58 see light
28:59 from the first galaxies
29:00 that were born in the universe.
29:01 So exciting stuff.
29:03 This is where we take
29:04 all the VIPs
29:06 that come through Goddard.
29:07 So you guys are definitely VIPs.
29:09 So my-- so yeah,
29:12 this is the world's biggest
29:13 clean room of its type.
29:16 And if you look right up there
29:18 you'll see the familiar pods
29:20 that have been on your truck
29:22 over the last year.
29:24 >> They're gorgeous.
29:26 >> They are, they are,
29:27 they're beautiful.
29:29 And so this big yellow structure
29:30 here is where
29:31 we're going to assemble
29:32 the mirrors onto the back
29:34 plane of the telescope.
29:36 So it'll sit flat.
29:37 And then that robotic arm
29:39 right over there
29:40 will take all the mirrors
29:42 and place them
29:43 down on the back plane.
29:44 So yeah, we have to
29:45 keep everything clean
29:46 so that once it gets out to
29:47 the clean part of the space,
29:48 it's, you know,
29:49 it's already clean.
29:50 >> It really is clean.
29:51 >> Yeah. And I mean,
29:52 you see the guys in the--
29:53 the bunny suits down here.
29:55 So they have to stay protected
29:58 and that whole wall over here
30:00 is air filters.
30:01 >> So I guess you can't
30:02 smoke in there.
30:03 [laughing]
30:05 >> Definitely not in there.
30:07 No, no.
30:08 No chicken wings
30:09 in the clean room.
30:10 >> No TVs.
30:12 >> Everything's so clean.
30:14 >> They're busy now.
30:15 >> This is just remarkable.
30:16 >> Yeah.
30:17 >> So when we watch
30:19 this thing take off
30:20 and we know that it's in space.
30:21 >> Oh, that sounds good.
30:22 >> We were-we were there.
30:24 >> Yeah.
30:25 >> We saw it.
30:29 >> It's a very tense scene
30:30 in here
30:31 when these two guys
30:31 from L3 Harris,
30:33 were working over
30:34 the primary mirror
30:35 to take those covers off.
30:36 They've been practicing
30:37 for a couple of weeks
30:38 before this,
30:40 but this is a very
30:41 delicate procedure.
30:42 Any misstep could damage
30:44 the primary mirror.
30:45 Even if they have
30:47 a drop of sweat
30:48 that falls off onto the mirror,
30:50 that could set the mission back,
30:51 you know, six months,
30:52 or a year or so
30:54 'cause they're working
30:54 to clean that.
30:55 >> At one point, they told us
30:57 they needed silence.
30:58 So a lot of us,
30:59 including myself,
30:59 just took a step back.
31:02 >> And this is something
31:03 we really do not like to do
31:05 on Webb or on any telescope
31:07 is be above the optics,
31:09 having humans above the optics.
31:10 So, and it's something
31:12 that I've done
31:12 quite a few times on Webb.
31:15 The technician is
31:16 on a diving board,
31:17 which is attached to a forklift.
31:19 Is that basically a harness
31:21 platform attached to a forklift
31:23 out over the primary mirror.
31:36 And then physically removing
31:38 a hard cover
31:39 from each mirror segment.
31:48 The mirror segments are
31:50 within millimeters
31:51 of each other.
31:52 And so it's very difficult
31:53 to remove something
31:55 without scratching
31:56 or damaging the optical surface.
31:58 So it was a very
31:58 delicate operation.
32:00 And, really just showed
32:02 how careful we were gonna
32:04 need to be.
32:06 >> It was wonderful.
32:08 It was wonderful
32:09 to see the instruments
32:10 coming to the clean room
32:12 and being aligned.
32:13 I think people know
32:14 once we add on these chambers,
32:16 it's a big effort
32:17 to keep them cold.
32:18 So we work 24 hours a day,
32:21 seven days a week,
32:22 for three months.
32:24 >> I mean, I knew that Webb
32:25 was a really big deal
32:27 because they were just
32:27 putting the mirrors together
32:28 when I got here.
32:29 I mean, you can't not appreciate
32:31 how it looks because it's huge
32:33 and it's gold
32:34 and it's beautiful
32:35 and it's just so different
32:37 from anything else.
32:38 But one of my like,
32:40 important life memories
32:42 really was the first time
32:43 going in the clean room.
32:45 And there's something
32:46 really special
32:46 about putting on a bunny suit,
32:48 especially for going in
32:49 for work.
32:49 Like I never lost
32:51 my appreciation
32:52 of putting on a bunny suit,
32:54 opening those doors, and like,
32:56 seeing a space telescope
32:57 in a room.
33:00 >> Generally, for the job,
33:02 we are documenting
33:04 what the engineers
33:05 and the technicians are doing,
33:07 and it's not typical
33:08 for producers
33:09 to come in overnight to shoot
33:12 sort of glamor shots
33:13 of something.
33:14 So we got permission
33:15 from the project
33:17 to come in and give Webb
33:19 a really special treatment
33:21 with these shots.
33:22 We got a lighting crew,
33:24 cleaned a lot of gear
33:26 into the clean room,
33:28 and these really became
33:29 some of the iconic shots
33:31 of the telescope.
33:37 >> I do think we got more
33:38 embedded into a team
33:39 than a lot of other
33:41 media groups have.
33:43 But yeah, you totally feel
33:44 a part of the team
33:45 when you are dressed
33:47 like the rest of the team,
33:48 and then you get to
33:49 know your team
33:52 from this lens.
33:54 You know, there's some people
33:55 that I only ever encountered
33:56 in the clean room
33:57 and was shocked
33:58 to see what they actually
33:59 looked like outside
34:00 of the clean room.
34:02 >> So, Paul, go ahead
34:03 and take us on a tour of--
34:06 of the facility.
34:06 And I might note,
34:07 this is the same facility
34:09 that for many years
34:11 was used to develop
34:13 the servicing hardware
34:14 for the Hubble Space Telescope.
34:15 So it's moving on to
34:16 its next generation.
34:17 Paul, it's all yours.
34:19 >> So there are
34:20 four instruments,
34:21 and the science instrument
34:22 module itself.
34:25 Webb has four state of the art
34:27 science instruments
34:28 and a guider.
34:30 The instruments consist
34:31 of a collection
34:32 of high resolution cameras
34:33 that give you
34:34 the pretty pictures
34:35 and spectrographs.
34:36 And the spectrographs
34:38 are the real scientific muscle
34:39 behind James Webb.
34:41 They're the ones
34:41 that can tease out the signals
34:43 that tells you the physics
34:44 and the chemistry
34:45 of the objects
34:46 they're looking at.
34:47 >> Behind every image
34:49 and spectra
34:50 that we are seeing from Webb,
34:52 our instrument has to work.
34:54 So NASA asked
34:55 the Canadian agency
34:56 to contribute
34:57 the Fine Guidance Sensor.
34:59 That instrument is one
35:02 that looks for a particular
35:03 star in the sky,
35:04 what we call a guide star.
35:07 Once it finds it,
35:08 it keeps that position.
35:10 The intent is to keep
35:11 the observatory
35:12 as stable as possible.
35:15 If you want to take a picture
35:16 with your camera
35:17 and your camera is moving,
35:19 that picture is
35:19 not going to be good.
35:21 So we do the same on orbit.
35:23 And with this instrument
35:24 that I look after and--
35:26 and that's a complex operation.
35:27 I'm an astrophysicist,
35:29 but I work as
35:30 a systems engineer on
35:31 the James Webb Space Telescope,
35:33 in particular, looking after
35:35 two of the instruments,
35:36 one of the science instruments,
35:38 and the instrument
35:38 that guides the telescope
35:40 to let it take
35:41 all these pictures
35:42 that we're seeing.
35:43 >> The system would not guide
35:44 without Beg.
35:45 She was the systems
35:46 person for the guider.
35:48 And it was such a complex
35:50 thing to do, guiding.
35:51 There are so many
35:52 technical details.
35:54 She had her arms around
35:56 all of it.
35:57 >> I don't know how
35:58 we could have gotten through
36:00 all of the complicated way
36:02 to verify that Webb could point
36:05 and track properly.
36:07 That was a complicated thing
36:08 that proved to ourselves
36:09 that that was all
36:10 going to work.
36:10 And Begonia was key to that.
36:12 >> And what was great about her
36:14 was she had this personality,
36:15 which was so positive.
36:18 >> This is where you have it.
36:19 >> All right.
36:21 >> I grew up in Spain.
36:22 I did my degree there,
36:23 then I did my Ph.D.
36:25 in astrophysics in the UK.
36:27 And then I think
36:28 for family reasons,
36:29 we ended up moving to Canada.
36:31 And in there
36:32 I moved to the private sector,
36:33 back to the space industry.
36:36 So I started actually in Canada
36:38 as the technical lead
36:39 for the two instruments
36:40 that were the contribution
36:42 to this telescope from Canada.
36:43 And of course,
36:44 all these things
36:45 are super careful.
36:46 You have each instrument
36:47 is built to meet
36:49 what they need to do on orbit.
36:51 Each of them has been tested
36:52 to show that they can survive
36:54 the worst part--
36:55 the launch with the vibration
36:56 and the noise, the acoustics.
36:58 We had three of these tests
37:01 on the chamber here at Goddard.
37:02 The first one had
37:03 two instruments,
37:04 the Canadian
37:05 and one of the European ones.
37:07 >> Good morning.
37:08 I'm Chris Scolese,
37:09 director of the Goddard
37:09 Space Flight Center.
37:10 Welcome to the center.
37:12 I'm standing in building 29.
37:14 And behind me
37:14 is the clean room
37:16 where we're building
37:16 the James Webb Space Telescope.
37:19 And as you can see behind me
37:20 are the 18 mirrors
37:22 that form the telescope.
37:24 Now, so that you can start
37:25 hearing about the telescope,
37:26 I want to introduce,
37:27 John Mather.
37:29 >> Thank you, Chris.
37:33 Well, welcome to our
37:35 science party here today.
37:36 I think it's a wonderful day
37:38 to celebrate.
37:38 And I want to tell you
37:39 a little bit about what
37:40 we're doing it for.
37:42 Today, we're celebrating
37:43 the fact that
37:43 our telescope is finished
37:45 and we're about to prove
37:46 that it works.
37:47 So that's a pretty important
37:48 milestone for today.
37:53 >> When you're launching
37:54 in a rocket,
37:54 it's what we call random vibe.
37:56 It's just random shaking, right?
37:59 We did what we called
38:00 a sine vibe test,
38:01 which is essentially
38:03 vibrate the thing
38:04 at a given frequency
38:05 where we literally will shake
38:07 the full telescope
38:09 to simulate
38:09 the effects of launch,
38:11 and then change the frequency
38:12 slowly and watch
38:13 how your system behaves.
38:14 It's a much more stressing test,
38:16 but that means
38:19 that you have the possibility
38:20 of over testing certain parts.
38:25 >> Certain parts resonate
38:27 at certain frequencies,
38:30 and when they start resonating
38:31 and you go three, four, five,
38:33 six, seven vibrations,
38:34 you start building up energy.
38:36 You start with a little shake
38:38 and then you go up
38:39 and you shake it
38:40 a little harder.
38:41 You shake it a little harder.
38:51 There was a loud popping sound,
38:53 and the sensors measured
38:55 something that was exceeding
38:57 the levels that we said
38:59 if this happens--
39:00 automatically shut down.
39:02 So we had an automatic shutdown.
39:04 And, I still very much remember
39:06 because it happened
39:07 on a Saturday
39:09 and I was actually home
39:10 during that particular test.
39:12 And I get a call,
39:13 there's going to be a telecon.
39:14 We just had
39:15 an automatic shutdown
39:16 and there was a loud
39:17 popping sound,
39:18 and the popping sound
39:19 gets your attention
39:20 because you're not supposed
39:21 to have a popping sound,
39:22 when you test flight hardware.
39:24 And I literally
39:25 drove into Goddard,
39:26 you know, I'm like listening
39:27 to the telecon and driving.
39:29 And we started discussing
39:31 whether that popping sound
39:33 could be potentially, you know,
39:35 something broke.
39:38 The telescope was
39:38 actually covered
39:39 in this plastic material,
39:40 and it's purged with dry gas,
39:43 but you can see through
39:44 the plastic material.
39:45 So I literally climbed
39:46 under the telescope
39:47 with the phone in my ear,
39:49 and I'm looking at it
39:50 and I said, you know,
39:50 I don't see anything
39:51 visibly broken,
39:52 like nothing came off.
39:55 And it was really difficult
39:56 to figure out.
39:57 But it turned out, you know,
39:58 we started running
39:59 a separate test
40:00 of some of the launch
40:01 restraint mechanisms
40:03 and the systems
40:04 that keep it latched up.
40:05 And we found out
40:06 what the problem was,
40:06 which was at a certain level,
40:08 these things
40:09 started to chatter.
40:10 And that chatter
40:11 sounded like the popping sound
40:13 that we heard.
40:14 We call that gapping.
40:16 We convinced ourselves
40:17 that we were going to be
40:17 okay for launch.
40:21 >> There is so much at stake.
40:23 I mean,
40:23 I love the drama of it all,
40:25 but you have to understand
40:26 that people's careers are made
40:29 from something like this
40:31 and Webb was a mission
40:33 that was going to
40:33 be spectacular,
40:34 whether that was good or bad,
40:36 if it failed or was successful,
40:38 it, you know,
40:41 it was gonna always
40:42 make history.
40:43 >> Everybody's pushing
40:44 to accomplish something
40:45 that's been outlined
40:46 as an idea,
40:47 the inspiration
40:49 of trying to discover something,
40:50 to build something
40:51 that's never been built before,
40:52 to discover something
40:53 that's never been known before.
40:56 It keeps us going.
40:57 And we are pleased
40:58 and privileged in our position
40:59 here at NASA
41:00 to be able to carry out this
41:02 on behalf of the country
41:03 and the world.
41:09 >> This center of
41:09 curvature testing
41:10 was in the main
41:11 Goddard Clean Room,
41:12 the largest clean room
41:13 at Goddard,
41:14 and it's a fantastic facility.
41:16 But even that is at the limit
41:18 of what we needed for Webb.
41:22 >> The telescope's
41:23 optical segment,
41:24 the part with the mirrors
41:25 and the science instruments
41:26 was built at NASA Goddard
41:28 in Greenbelt, Maryland,
41:29 then packed and flown
41:30 to the Johnson Space Center
41:31 in Houston, Texas.
41:35 ♪♪
42:00 >> We needed
42:01 a very large chamber
42:02 to test Webb end to end,
42:04 optically, so we wound up
42:06 using JSC Chamber A,
42:07 which is the same vacuum chamber
42:09 that was used to test
42:10 the Apollo landers.
42:11 >> It's been a long way,
42:13 but we're here.
42:15 >> Chamber A was designed
42:16 to test the Apollo surface
42:17 and command modules,
42:18 so it had a rotating floor
42:21 and a top and side
42:23 solar simulators,
42:24 so they would simulate
42:26 the orbit of traveling
42:28 to the Moon, where the, uh--
42:30 passive thermal control system
42:31 for the Apollo,
42:32 would rotate, kind of do
42:33 what they call
42:34 a barbecue roll,
42:35 and practice its heating
42:36 and cooling.
42:38 And we did that with
42:38 actual astronauts.
42:39 It was before my time,
42:40 so when I say we did that,
42:41 I'm talking NASA, not--
42:42 not me, personally.
42:46 >> It didn't really get used
42:47 very much.
42:49 I believe there was a--
42:50 a worry that it might be
42:52 mothballed or demoed,
42:54 and they wanted to
42:55 preserve it, and they made it
42:57 a national historic landmark.
43:01 >> So Chamber A,
43:01 with its 40 foot diameter door,
43:03 is a pop culture icon.
43:05 It's been in music videos,
43:07 like, Aerosmith.
43:10 It's been in Armageddon
43:13 and Transformers 3.
43:15 >> Still working on the preps
43:16 for Webb when we were trying
43:18 to clean up the high bay
43:19 for the movie Transformers 3.
43:22 And they had to get permission
43:23 from Webb to film that
43:26 so as not to interfere
43:26 with the schedule
43:27 of the telescope.
43:29 The Webb was the-- really,
43:30 is the most complicated thing
43:31 that they had done
43:32 since Apollo.
43:37 >> The goal of the tests
43:38 of the telescope
43:39 in Chamber A really was
43:40 to make sure everything
43:41 was functioning properly
43:42 at the very cold temperatures,
43:44 and all the optical systems
43:45 worked properly
43:46 at cold temperatures.
43:49 It was the one time
43:49 we could test
43:50 the entire telescope
43:51 at the very cold temperatures.
43:54 The test was nominally
43:55 a three month test,
43:57 where we would cool
43:58 the telescope down to--
43:59 almost a month to cool
44:00 the telescope
44:02 to this minus 400 degree
44:03 Fahrenheit temperature.
44:05 And then a little over
44:05 a month, we'd stay at
44:07 these very cold temperatures
44:08 and it was the first time
44:09 we were gonna test
44:10 the full primary mirror
44:12 as a mirror, because
44:13 we'd only tested
44:14 individual mirrors
44:15 at that point, so we had
44:16 to see the shapes
44:17 of all that matched.
44:18 It was the first time
44:19 we were gonna test
44:20 the telescope sort of
44:21 end to end.
44:22 Most of the cooling
44:23 that we do actually is done
44:24 with a very large
44:25 liquid nitrogen canister
44:27 inside of the vacuum chamber.
44:29 We run liquid nitrogen
44:30 through it, and that
44:31 cools us down to about
44:32 75 degrees above
44:33 absolute zero.
44:34 To get even colder, we'll have
44:35 a liquid helium system
44:37 inside of that, but most
44:37 of the cooling capacity comes
44:40 from the liquid nitrogen itself.
44:46 The sequence of the test
44:47 was it takes about 30 days
44:48 to cool everything down.
44:50 We had about 30 days
44:51 planned for testing,
44:53 and then about 30 days
44:54 to warm everything up.
44:55 >> So when you are planning
44:57 for one of these tests
44:58 in a chamber, you always do
44:59 the contingency procedures.
45:01 If this goes wrong,
45:02 what will I do?
45:04 And I still remember
45:05 our first meeting
45:07 for Houston where we go
45:08 through all the things
45:09 we can do if the chamber
45:10 loses power,
45:11 if this instrument
45:12 doesn't work, whatever.
45:14 And then they say, well,
45:15 we also have to plan
45:16 for a hurricane.
45:17 And I remember being there
45:18 saying, "What?"
45:20 Are you kidding me?
45:27 >> We started hearing about
45:28 a storm that was brewing,
45:30 a tropical storm.
45:31 And we all kind of gathered
45:32 in a room, and we started
45:33 talking about
45:34 contingency planning.
45:35 Because we had thought
45:36 a lot about potential
45:37 for storms and hurricanes.
45:39 And we did have
45:40 a five day supply
45:41 of liquid nitrogen in case
45:42 there was ever a big storm.
45:44 And then we got ready.
45:45 The storm got upgraded,
45:46 and upgraded, and upgraded
45:48 to category 3
45:49 and category 4.
45:51 >> And so we were monitoring,
45:52 and I remember finishing
45:54 my shift, and hurricane--
45:57 it seemed that it was
45:58 going to come.
45:59 And we were like,
46:00 well, what should we do?
46:02 And they said, "We'll know.
46:03 So don't worry. Go home."
46:05 I remember going for dinner
46:07 with some colleagues.
46:08 We went to the restaurant
46:09 for dinner, and when we left,
46:12 the water-- you know,
46:14 we were paddling in water.
46:15 The water in the street
46:16 was as high as the sidewalk.
46:22 So that night,
46:23 the hurricane hit.
46:36 >> And Saturday morning came,
46:37 and you know, the sky cleared
46:39 a little bit, and we said,
46:39 "Okay, it looks like we made it
46:41 through the worst of it."
46:43 Storm had kind of hit us.
46:44 And so, you know, we had
46:45 all these air mattresses,
46:46 and a couple people
46:47 stayed there Friday night.
46:48 But we actually started doing
46:49 testing again, and, you know,
46:52 Saturday afternoon we got
46:53 the very first measurement
46:54 of the primary mirror.
46:55 The very first time we saw
46:56 the entire primary mirror
46:57 was right after the hurricane
46:59 hit the next day.
47:04 But literally, within
47:06 an hour or two of getting
47:07 those first measurements,
47:10 several of us had actually
47:11 gone out to dinner
47:12 to kind of celebrate.
47:12 We made it through it,
47:13 and while we're there,
47:14 we get an email from
47:16 the meteorologist that
47:17 it looks like the storm
47:19 is kind of coming around
47:20 in a spiral, and we're gonna
47:22 get a much, much bigger hit
47:24 that Saturday night.
47:28 >> Rockport, Texas feeling
47:30 the full force
47:31 of Hurricane Harvey
47:32 as the storm makes landing--
47:33 >> We're measuring in feet.
47:35 >> ...one of the most powerful
47:36 storms in United States--
47:37 >> 130 miles an hour winds
47:39 and a treacherous storm--
47:41 >> Search and rescue efforts
47:42 are underway.
47:47 >> You know, I think we got
47:47 51 inches of rain that week,
47:49 but over 42 inches of it
47:51 was in one night.
47:53 And it was insane.
47:54 And it was so intense
47:55 that literally water started
47:56 coming through the roof.
47:58 So we started having
47:58 to cover equipment.
48:01 >> I mean, you are there,
48:02 and you see the water
48:03 come in, and then you
48:04 see them come in
48:05 and setting everything up.
48:06 So we were just dealing
48:07 with it day to day, you know?
48:09 It was incredible to see
48:10 but at the same time,
48:11 we were just working
48:13 and trying to, uh,
48:15 accommodate all of this.
48:17 >> And it turned out that
48:18 the storm lingered
48:19 for a full five days.
48:21 We had a five day supply
48:22 of liquid nitrogen,
48:22 but it was coming up
48:24 on five days.
48:25 And there was a point at which
48:27 we would have had to do
48:28 what's called
48:28 an emergency warmup,
48:30 and warm things up
48:31 even faster than planned
48:32 in a way that we had
48:33 never done before
48:34 in any of the rehearsals.
48:36 >> Pieces would have broken.
48:37 You just can't have things
48:39 change temperature that quickly
48:41 with those kind of materials
48:42 and expect them to survive.
48:44 >> If we couldn't get
48:44 some liquid nitrogen--
48:46 but the problem was,
48:47 the supplier of
48:48 the liquid nitrogen
48:49 was underwater.
48:52 >> It was-- a state
48:52 of emergency was declared,
48:53 and so getting our shipments
48:55 of liquid nitrogen was
48:57 not the priority of the state,
48:59 and we had to, uh,
49:00 make it happen.
49:02 >> The center did a great job
49:03 of using our center resources
49:05 to grab liquid nitrogen
49:06 from every other point
49:07 on the center and redumping it
49:08 into our tanks.
49:10 >> And the teams,
49:11 many of them slept
49:12 in the control room.
49:13 Hurricane Harvey was--
49:15 was one of those times where
49:17 the team gave up everything
49:18 for the protection
49:19 of the telescope.
49:21 >> We were literally at
49:22 the very final day,
49:23 I remember, you know,
49:24 coming in really early
49:25 in the morning, and after
49:27 several hours, we finally
49:28 got the president
49:29 of the division that sort of
49:30 ran the liquid nitrogen,
49:32 and they were able
49:33 to find a driver,
49:34 and find a truck,
49:35 and make a couple trucks
49:37 of supply.
49:38 And finally, they came
49:39 that night, or--
49:40 The next morning, I think,
49:41 we would have had to do
49:41 an emergency warmup,
49:43 and, uh, crossed our fingers
49:44 a little bit.
49:45 But they came, and I remember,
49:46 because we had a video camera
49:48 of the place where the trucks
49:49 would pull up.
49:50 And when we saw the trucks,
49:51 the entire control room
49:52 broke into applause.
50:10 >> I was one of
50:12 the first people
50:13 in the chamber after.
50:15 When we opened it up,
50:15 it was actually on my birthday.
50:19 And it was one of the most
50:21 powerful experiences of my time
50:23 working on Webb.
50:24 The chamber is amazing
50:26 with the door shut.
50:27 It's all black.
50:28 It's designed to be
50:31 not reflective for light,
50:33 and so we went in
50:35 with flashlights
50:35 to do this inspection,
50:36 and it's-it's similar
50:38 to spelunking.
50:39 It's like going into a cave
50:41 that has a space telescope
50:43 in it.
50:44 It is absolutely
50:46 the coolest thing.
50:47 We need to climb up
50:48 on scaffolding to get
50:50 to see the primary mirror.
50:52 And so, uh, we went
50:54 into the chamber and climbed up
50:55 on the scaffolding
50:56 to take a look,
50:57 and it was brilliant
50:59 to see the gold mirrors
51:01 against the black background
51:02 in this chamber.
51:05 Well, when I got past
51:06 the beauty of seeing
51:08 the gold mirrors again,
51:09 they were absolutely filthy.
51:11 So this was, um--
51:14 >> Why was that?
51:15 >> That was because
51:16 the fallout from the chamber,
51:18 so during cryogenic testing,
51:20 all of the particulate
51:22 and everything that was--
51:24 had collected inside the chamber
51:25 for the last 50 years
51:27 fell onto the exposed
51:28 cup-up
51:29 gold primary mirror segments.
51:31 And so they were in
51:32 pretty bad shape
51:34 after the cryo testing.
51:35 >> A decision was made
51:37 to clean the mirrors,
51:39 and when you look at
51:42 multi-million dollar
51:44 beryllium-- gold coated
51:45 beryllium mirrors,
51:48 you're not using squeegee
51:50 and some Windex.
51:52 >> So we rotated it
51:53 so the gold primary mirror
51:56 was cup-down.
51:56 The big fear is that,
51:58 especially on a coated optic,
51:59 that through cleaning it
52:01 we're going to
52:02 damage the coating,
52:03 or scratch the mirror,
52:05 or put some other substance
52:07 on the mirror
52:08 from what we're using to clean.
52:10 >> Larkin and his group
52:12 from Ball went in
52:13 in a prone position with
52:15 a very special kind of brush,
52:18 an IPA, where they cleaned
52:20 all of the-- the primary
52:22 and the secondary mirror
52:23 with tiny little brushstrokes.
52:27 Maybe each stroke was
52:30 a half an inch to an inch.
52:32 And so it was incredibly
52:35 detailed work.
52:36 Um, it took a while.
52:40 >> I was within inches
52:40 of the telescope
52:41 for 10 days, and being under
52:42 that gold coated
52:44 primary mirror there
52:45 is something incredible to get--
52:47 to put the energy
52:48 into cleaning that mirror
52:49 and knowing that it's going
52:50 to be receiving photons
52:52 from stars and it's going
52:53 to be helping to reveal
52:55 the universe and I get to
52:57 spend time getting it
52:59 prepared for that.
53:01 Cleaning it and putting it
53:02 in the best configuration
53:03 and the best condition it can be
53:04 for what it's gonna do
53:06 in the future.
53:22 >> The other tough things
53:23 when it comes to deployments
53:25 are obviously the big,
53:26 flexible, floppity things
53:27 like the sunshield.
53:29 Of all the deployments,
53:30 that's the one that really
53:31 is the toughest for many of us.
53:33 Because the mirrors,
53:35 as just an example,
53:37 they are big.
53:38 They have to work.
53:39 But they're also very rigid
53:40 and we have a lot of experience
53:41 with how to move
53:42 big rigid things
53:43 and latch them in orbit.
53:44 But the floppity things,
53:46 the flexible things
53:47 like membranes, making sure
53:48 they go where you want,
53:50 and more importantly
53:51 they don't go
53:53 where you don't want them to go,
53:54 that's tough.
53:56 >> How do I feel about
53:56 the sunshield design.
53:58 Boy, um, uh, so here's
54:00 the thing.
54:00 I personally think that
54:03 the sunshield design
54:04 is very complicated.
54:05 There are a lot of pulleys,
54:07 and cables, and motors,
54:09 and drives.
54:10 On the other hand if you
54:10 ask me, hey, go simplify
54:12 the sunshield design,
54:14 I would not know where
54:16 to begin.
54:17 It's-it's-- I think,
54:20 complicated by necessity.
54:21 It's huge, and it has
54:24 to be lightweight,
54:25 and it has to deploy,
54:27 and it has to
54:28 deploy positively.
54:29 We have to have tension on it.
54:32 It can't be loose or floppy.
54:34 It has to stow
54:35 and get folded.
54:36 You bring in all
54:37 of these constraints,
54:38 and you think about design
54:39 as a space, right?
54:41 You know, certain things
54:42 cut off a giant portion
54:43 of that space, and you bring in
54:44 all these constraints,
54:46 you're left with
54:47 a relatively narrow box
54:48 in which you can design.
54:50 And, you know, because
54:51 it exists, it's hard to--
54:51 to imagine it being
54:53 any other way.
54:54 It's like your life, right?
54:55 You grew up the way you are,
54:57 and-and you are who you are
54:58 because of the things
54:59 that shape your existence.
55:00 And so it's hard to say
55:01 if-if you had a do-over
55:03 if you'd be any different.
55:06 >> The sunshield is the key
55:07 to the entire Webb observatory.
55:08 You know, it's the thing
55:09 that blocks out the heat
55:11 from the Sun, the Earth,
55:12 and the Moon from
55:12 Webb's optics and instruments,
55:14 allowing them to get down to
55:15 those super cold temperatures
55:17 necessary for them
55:18 to operate.
55:19 >> There is not a book.
55:20 There's no design standards.
55:22 The sunshield is--
55:23 is so novel that we can't
55:25 find anything like that
55:26 that's been flown
55:28 that has these crazy things
55:30 it needs to do.
55:31 >> The sunshield turned out
55:32 to be, I think, maybe
55:33 a bigger challenge
55:34 than some people thought,
55:37 because, you know,
55:38 although there were people
55:39 experienced at deploying
55:41 large things that have
55:42 floppy elements to them,
55:44 it's still a hard problem,
55:46 and this was
55:46 a unique sunshield.
55:49 >> And so we wanted to test out
55:50 things like, you know,
55:51 how do we actually
55:52 just handle this material?
55:54 It's very thin.
55:56 There's five layers,
55:58 and the thinnest layer
55:58 is one mil, which is
56:00 one thousandth of an inch.
56:02 So, you know, much thinner
56:03 than your hair.
56:04 We wanted to make sure
56:05 we could just handle it
56:06 without ripping it.
56:07 If you ever try to fold origami,
56:09 you know that paper can really
56:10 only be folded a few times.
56:12 It makes creases, there's lines.
56:13 >> The big thing with
56:14 the sunshield early on
56:15 was how do we support it
56:16 during launch?
56:17 You know, you--
56:18 it-it-it's floppy, you know.
56:20 You got these five things
56:21 that all fold up.
56:23 You still have to hold it down
56:24 for launch, or it'll sag.
56:27 It'll move around
56:28 and tear itself up.
56:29 So you have to give it support.
56:30 The launch environment's
56:31 rather violent.
56:38 >> To hold the membrane down
56:39 to the structure,
56:40 you have to hold it down
56:41 with some release devices.
56:42 And there's 107 of them.
56:44 >> You can't even imagine
56:45 the number of holes that had
56:46 to be precisely located
56:47 in these membranes.
56:48 And then when you fold it
56:49 all up, the--
56:50 all these holes have to line up.
56:51 Oh, by the way,
56:52 when it's deployed,
56:53 these-these holes can't be
56:55 such that sunshine
56:57 can get through them lined up.
56:58 So it's an incredibly
57:00 complex problem geometrically.
57:03 >> Webb is massive.
57:04 It is about three stories high
57:06 and about the size
57:07 of a tennis court.
57:08 Just try to imagine
57:09 Roger Federer and Rafa
57:11 running back and forth
57:12 on their paths of our telescope.
57:14 Just, uh, picture that
57:16 and just imagine how
57:17 large this is and what
57:18 a hard job that is.
57:21 >> So NEA is
57:22 a Non Explosive Actuator.
57:25 So these are the types
57:26 of release mechanisms
57:27 that we use on Webb.
57:29 The majority of
57:30 our release mechanisms were
57:31 all on the sunshield.
57:34 >> And we're going to skewer it.
57:35 And we're going to pin it
57:36 to this big structure.
57:38 And then when we get on orbit,
57:39 we'll retract those pins
57:41 and everything will be good.
57:42 >> And-And I-I remember
57:43 a meeting where we were like,
57:44 yeah, it sounds like
57:45 a really bad idea.
57:52 And I was actually out there
57:53 doing my rotation one time
57:55 when the head of
57:57 integration test for-for
57:58 Northrop was gonna take me
57:59 in the clean room
58:01 to do an inspection.
58:02 We're walking into
58:03 the clean room, he says,
58:04 you know, I have to--
58:05 I have to warn you,
58:06 there-there might be a little
58:07 bit of a hubbub in there.
58:08 And I said, why is that?
58:09 And he said, well, they-they
58:10 found some screws and washers
58:11 on the ground
58:13 after this last test.
58:17 >> Every single one of
58:17 those fasteners,
58:18 a thousand of them.
58:20 When the screw goes through
58:21 the end of the nut,
58:22 it leaves a sharp edge.
58:24 That sharp edge could catch
58:25 a cable or scratch
58:26 a 1,000th of an inch
58:28 thick membrane,
58:30 and punch a hole in it that can
58:31 lead to an end of a mission.
58:34 >> You know, as we
58:35 really dug into the issue,
58:37 you know, it is-- it was--
58:38 it was a bit of
58:39 a subtle interface thing.
58:40 And one of the reasons
58:41 you test things is
58:42 to uncover these issues.
58:44 But when you're
58:45 a really large sunshield
58:46 with a lot of screws and nuts
58:48 and washers, you know,
58:50 one small thing can multiply,
58:53 and then it gets multiplied.
58:55 You know, we were-we were like
58:57 in a goldfish tank, you know.
58:59 The entire planet would read
59:00 about it in, you know--
59:01 via newspapers,
59:02 and you just knew that one
59:03 was gonna-was gonna be
59:04 that kind of issue
59:05 from the beginning.
59:06 And so that--
59:07 I think that created
59:08 a lot of stress for all of us.
59:09 And that was a very big hit.
59:11 Took about 11 month hit
59:12 on our schedule.
59:15 >> Our architecture, especially
59:16 in those deployments,
59:17 had, what, 344 single point
59:19 failures, right?
59:21 If you're going to have
59:22 344 single point failures
59:23 and they're all dependent
59:25 on the last reset
59:26 on the last installation,
59:28 you have to have an environment
59:29 of absolute openness
59:31 and honesty.
59:32 And the fear that comes
59:33 from the-the politics
59:34 and that kind of stuff
59:36 is your chief enemy to that.
59:37 >> I mean, it's crushing, right?
59:39 The team is now sunk.
59:40 It's out there in the news.
59:41 We're getting less,
59:42 and we now know
59:43 we're not going to make
59:44 our launch date again.
59:47 >> Mr. Bridenstine, uh,
59:48 welcome back.
59:49 >> Thank you.
59:50 >> You know, how much has
59:52 changed since 1996?
59:54 >> Oh, my gosh--
59:55 >> When-when this was first
59:56 put out there at $500 million.
59:58 Can you even talk about
59:59 how much cosmology has changed?
60:02 >> Uh, it's-it's
60:02 a wonderful question.
60:03 And when you think of
60:05 the universe at large,
60:06 NASA is learning new things
60:08 every single day,
60:09 how the universe is expanding
60:11 and not just expanding,
60:12 but expanding at
60:13 an ever increasing rate.
60:14 It's actually accelerating.
60:15 And-and what is causing that?
60:17 And can James Webb help us
60:19 understand that, you know,
60:19 at the edge of the universe,
60:21 there are galaxies, in essence,
60:23 disappearing because
60:24 they're accelerating faster
60:25 than the speed of light.
60:26 >> Wow.
60:27 >> So those galaxies,
60:29 the light from them,
60:30 if they're faster
60:31 than the speed of light,
60:31 that light can't get
60:32 back to Earth, which means
60:33 there's a whole lot
60:34 of things we don't understand
60:36 about the physics, astrophysics
60:38 that this particular spacecraft
60:41 is going to help us learn.
60:42 Going back to the very beginning
60:43 of cosmic dawn,
60:44 we're gonna learn how did
60:45 the very first galaxies form?
60:47 What did that first light
60:49 look like?
60:52 >> I really want to thank you
60:53 for the comprehensiveness
60:54 of that answer, because
60:55 the world and science itself
60:57 is changing in ways
60:58 that impact a project
61:00 that we have completely
61:01 different expectations for
61:03 in 2018.
61:03 >> There's a whole host
61:04 of capabilities that
61:05 we can't even predict yet
61:06 until it's on orbit,
61:08 and we're doing everything
61:09 we can to get there.
61:12 >> Mr. Chairman, I just wish
61:13 we had a head of NASA that
61:14 was excited about this project.
61:16 >> Yeah.
61:17 >> Now when you ask
61:18 your first question,
61:19 I could see that answer
61:20 going on for a couple of hours,
61:21 but I thought it was
61:22 a good answer.
61:23 >> Outside of family and,
61:24 you know, many other things,
61:25 it's hard to imagine
61:26 a prouder day in my life
61:28 watching him.
61:29 He got grilled,
61:30 and got challenged
61:30 and gave honest answers
61:31 and sat there
61:33 and-and went through that
61:34 and knew he-- you know,
61:35 he had to take it.
61:36 And in the end said,
61:38 but we're gonna get this right.
61:39 >> And for the first time,
61:41 we are on the homestretch.
61:43 [ music ]
62:08 >> 2020 comes around.
62:11 And COVID hits.
62:12 And at the time, it was like,
62:14 you gotta be kidding me.
62:16 >> When people ask me
62:17 what the biggest challenge
62:18 on Webb was,
62:19 I almost always say COVID.
62:21 Now we had technical issues
62:23 and technical challenges,
62:24 but people's health
62:26 weren't being affected.
62:26 Well-- I take that--
62:28 you know, mental health
62:29 maybe got affected,
62:30 but direct threats
62:31 to your health
62:32 did not come from that.
62:35 This was a direct threat
62:37 to our team
62:38 and to-- the most valuable
62:39 resource of our team
62:40 was the people.
62:41 Not money, not schedule,
62:43 nothing, it was the people.
62:44 >> Meanwhile, we're already
62:45 wearing masks in the highbay.
62:46 We were-we were
62:47 way in advance of that, right?
62:49 Because if you look at
62:49 all the old shots of Webb,
62:51 oh, look at them wear a mask.
62:52 Was COVID back in 2011?
62:53 Like, no, we wore masks to keep
62:55 the mirrors clean, right?
62:56 So we already had
62:57 mask practice down,
62:58 and we said let's keep going.
63:01 So we kept a core team.
63:03 That core team came in
63:05 heroically.
63:07 Never stopped.
63:08 And the team who never stopped,
63:11 we all owe an incredible
63:12 debt of gratitude for
63:13 because I tell you,
63:14 if we had stopped,
63:16 I don't know what it
63:17 would've taken to restart.
63:21 >> There was just one last
63:22 sunshield deployment test
63:24 before Webb was packed up
63:25 and sent to French Guiana.
63:27 >> This was gonna be
63:28 the last time Webb
63:30 was deployed ever
63:33 on the planet.
63:35 And this was the culmination
63:37 of the effort
63:38 of thousands of people
63:39 around the world.
63:40 So I wanted to do
63:41 something spectacular for this.
63:43 And we got a gyro stabilized
63:45 camera system,
63:46 and we mounted it underneath
63:47 one of those lifts
63:48 that they use in the clean room.
63:50 And this lift can go up
63:51 about 65 feet.
63:52 And I believe during that time,
63:54 we captured some of
63:55 the most amazing images
63:57 of the telescope
63:58 in its final deployed state.
64:18 >> The last step as
64:19 we were going through
64:20 our deployments was removing
64:22 that lens cap
64:24 right before the sunshield
64:27 was folded up.
64:29 The instruments are
64:30 very sensitive to light,
64:32 that are designed
64:33 to be extremely sensitive,
64:34 so they can sense
64:35 far off faint stars.
64:37 And so lights from
64:38 the clean room
64:39 could potentially damage
64:41 these instruments.
64:42 And so we had kept
64:42 this cover in place
64:43 not only for contamination
64:45 to keep any sort of debris
64:47 or-or, uh, small particulate
64:49 out of the micro shutters,
64:50 but also to optically protect
64:52 the instruments from, uh, light
64:54 that could potentially damage
64:55 the sensors.
64:56 This lens cap was removed
64:58 at the last possible moment
64:59 while we were stowing
65:00 the-the fore sunshield,
65:02 and I was the one to do that.
65:06 [ indistinct chatter ]
65:13 >> Yeah, you're all set.
65:15 >> Going up.
65:17 >> Going up.
65:18 >> I'm a very even keel person,
65:19 and-and, uh, am able to perform
65:22 these tasks in a really
65:24 focused and relaxed way
65:25 without letting my emotion
65:27 be a part of it.
65:28 And this one got me.
65:31 This one was different.
65:35 It was the last time
65:36 that I would be
65:37 in front of the mirrors
65:38 in that way.
65:39 It was the last time
65:40 that I would see the--
65:42 inside the aft optics assembly,
65:44 see tha tertiary mirror
65:45 and the fine steering mirror
65:46 and the instruments.
65:47 And so removing this cover,
65:49 uh, it was-it was
65:52 actually a pretty emotional
65:54 moment for me.
65:57 [ music ]
66:21 I was able to keep it together
66:23 and not drip tears anywhere.
66:25 And get the cover off perfectly,
66:27 and get Webb ready to go.
66:29 But it was
66:30 a very emotionally impactful
66:32 moment for me,
66:33 uh, saying goodbye
66:34 to that part of Webb.
66:36 >> What's the one aspect
66:37 of the design that you lose
66:39 the most sleep over?
66:40 >> Ah, good question.
66:41 I don't lose sleep over this.
66:43 I did that already.
66:45 I think what worries
66:46 most people the most
66:47 is that deployment.
66:48 It's really hard to prove
66:49 that they will do
66:50 the same thing next time
66:51 that it did last time.
66:53 With the deployment,
66:54 you fold it back up
66:55 one last time,
66:56 and then you push the button
66:56 one last time
66:57 and it's gotta be the same.
66:58 So this is-this is tricky
67:00 and the deployments
67:01 cannot possibly be tested
67:03 in exactly the same condition
67:04 they will see in space.
67:05 Zero gravity, cold vacuum.
67:07 We don't got that here.
67:08 That's what I think most people
67:10 worry about the most.
67:11 >> And the expectation
67:12 is probably the hardest thing,
67:14 I would say.
67:15 The-the weight of, uh,
67:17 knowing that this has
67:19 to go right the first time
67:21 and the only time, and there is
67:23 really no room for error.
67:24 Carrying that around for
67:26 however long we've all been
67:28 on the program, um,
67:30 was-was a thing.
67:33 My boss, Jim, uh, used to say
67:35 that we're like deep sea fish,
67:38 under sort of constant pressure.
67:40 And that, uh,
67:42 once Webb was launched,
67:44 we wouldn't really know
67:45 what to do with ourselves
67:47 because all the pressure
67:48 would be off.
67:49 >> Webb is by far the largest
67:51 piece of flight hardware
67:52 that we've moved.
67:53 The transporter is
67:55 the largest transporter
67:56 that I know of in history
67:58 to come out of
67:59 Goddard Space Flight Center.
68:02 And essentially what STTARS
68:03 is, is a mobile clean room
68:05 moving JWST from one location
68:07 to the other
68:08 while it's still inside
68:09 of a clean room environment.
68:11 >> And so it was goodbye
68:12 for the entire team
68:13 that had been a part
68:14 of the observatory,
68:17 and spacecraft, integration,
68:18 and everything for 20 years
68:20 at that point.
68:23 >> There was nothing easy
68:24 about Webb at all.
68:25 I don't care what aspect
68:27 of the mission you looked at.
68:28 So moving around
68:31 that huge behemoth
68:33 of a telescope became
68:35 extraordinarily challenging.
68:38 >> The 405 is just something
68:40 that is a big part
68:41 of the heart of L.A.
68:42 and that whole community,
68:43 and so it's really neat
68:44 that we got to send it
68:45 right through the heart of L.A.
68:46 and off to the sea in that way,
68:48 and be a part of that.
68:51 [ music ]
69:17 >> It's going four times
69:18 farther away
69:19 than the Moon over there,
69:20 and it's going to be there
69:21 for eternity.
69:23 [ music ]
69:32 [ cheering ]
69:34 >> Goodbye!
69:35 >> Goodbye! [ indistinct ].
69:50 >> Whoo-ee!
69:58 >> We're shipping
69:59 the James Webb Space Telescope
70:00 to its launch site
70:01 in French Guiana.
70:02 It just left port in
70:04 uh, the Naval Weapons Center,
70:06 Seal Beach.
70:07 And after 25 years
70:12 of development,
70:13 it's headed for its launch site
70:15 and its final destination
70:17 in space.
70:28 >> One of the interesting parts
70:29 about when we departed
70:30 is security.
70:31 How did we make sure
70:32 that we didn't encounter
70:33 any sort of pirates,
70:35 or cause any disruption
70:36 to our shipment?
70:37 In the maritime industry,
70:39 you can track ships
70:40 everywhere they go.
70:41 As we are departing
70:42 from Seal Beach,
70:43 there-there were posts
70:44 on the internet,
70:45 because there is a--
70:46 a vibrant community of people
70:49 that are very interested
70:50 in what's happening with JWST.
70:52 And so on-on Reddit, actually,
70:54 there was one particular person
70:55 that was really good
70:57 at tracking the ship,
70:58 and he was--
70:59 he was giving a great log
71:01 to the general public
71:02 of where the ship was going.
71:04 I was actually able
71:05 to reach out to him,
71:06 explain to him, you know,
71:08 it would be great of him to--
71:10 to maybe just add
71:12 a little bit of vagueness
71:14 to where the ship
71:15 was actually going,
71:16 the direction,
71:17 just a little bit less detail.
71:18 And surprisingly,
71:19 he was great about it.
71:20 You know, he-he went about
71:23 posting and-and saying that--
71:25 got a little bit more
71:26 generic with the locations.
71:40 >> Well, Kourou is actually
71:41 a good place for a launch site,
71:43 very close to the equator,
71:45 and that helps you
71:45 getting an extra spin
71:47 when you launch.
71:48 >> It was a bubble
71:49 that we were there,
71:50 mostly hidden from the pandemic,
71:52 able to work
71:53 and just focus on-on Webb
71:56 and getting it ready
71:56 for launch.
72:03 >> The weather
72:03 is pretty volatile.
72:04 I mean, you're on--
72:05 you're in a tropical
72:06 environment,
72:07 even in December.
72:09 In fact, it caused one
72:11 launch delay of a few days.
72:13 Under the umbrella
72:15 of that launch delay,
72:15 no pun intended,
72:16 the technical folks
72:18 preparing Webb for rollout,
72:20 had a bit of extra time
72:22 to be able to attend
72:23 to last minute preparations.
72:34 >> It was pouring.
72:35 I got soaked more than I had
72:36 any other time in Kourou,
72:38 standing out there
72:39 with the team,
72:40 watching it rolling out
72:41 to the launch.
72:42 And it was--
72:43 it was an absolute party
72:45 in the rain.
72:51 >> We weren't going any place
72:52 until Webb was off the ground
72:54 safely on its way.
72:56 So it's not like
72:58 we had a a plane to catch
72:59 or a train to catch, right?
73:01 We were a captive audience.
73:03 >> A really neat thing happened
73:04 because of the way
73:05 that launch had been delayed,
73:08 and it ended up
73:09 being on Christmas Day.
73:11 >> So when the clock hit 12,
73:13 you know, it was-it was--
73:14 it was a privilege of mine
73:15 to wish everybody
73:16 a happy holiday
73:17 and to thank them
73:18 and then mention to them
73:19 that their families were--
73:20 you know, history had put them
73:22 in that place at that time
73:24 for a reason, you know.
73:25 And I didn't go into it,
73:26 but it was like, you know,
73:27 I kept thinking about
73:28 the Apollo 8 launch,
73:30 you know, Christmas Eve,
73:31 you know, reading about--
73:32 from the book of Genesis--
73:34 you know, it's famous, right?
73:34 >> Just now approaching
73:36 the lunar sunrise.
73:37 And for all the people
73:40 back on Earth,
73:42 the crew of Apollo 8
73:44 have a message that
73:45 we would like to send to you.
73:47 In the beginning
73:48 God created the heaven
73:50 and the earth.
73:51 And the earth was
73:52 without form and void,
73:55 and darkness was upon
73:56 the face of the deep.
73:58 And the spirit of God moved
74:00 upon the face of the waters.
74:02 And God said,
74:04 let there be light,
74:06 and there was light.
74:08 >> The reading about,
74:09 you know, the first light.
74:10 And here we are launching this--
74:12 this incredible machine
74:13 that's intended to pick up
74:15 that first light.
74:16 [ choir singing faintly ]
74:24 >> When the Webb telescope
74:25 was launched,
74:26 I was just sitting on the sofa
74:27 with my wife,
74:28 because COVID was happening.
74:30 So everybody stayed home.
74:31 We didn't have
74:32 any launch parties.
74:33 Okay, well, that's how it goes.
74:35 People thought, well,
74:36 surely you must be
74:36 on the edge of your chair,
74:38 because you've been
74:39 working on this forever,
74:40 and it could go wrong.
74:41 That's not how I felt.
74:42 I felt, of course
74:43 it's going to work.
74:44 We've done everything
74:45 we should do.
74:46 >> I haven't yet
74:47 thought a lot about
74:48 what is the proper Zen mode
74:49 to get into for launch day.
74:51 By that point,
74:52 the die is already cast, right?
74:53 Either we built it correctly
74:55 and it's going to work,
74:56 or we're going to find
74:57 surprises on orbit.
74:58 But it's time to go find out.
74:59 >> It's all looking very good
75:01 here at the spaceport
75:02 for a Christmas Day launch.
75:05 Operations running smoothly,
75:06 the countdown
75:07 ticking over nicely.
75:09 All the systems are green
75:11 and we are go for launch.
75:13 We're looking at
75:14 launch pad number three,
75:16 the James Webb Space Telescope,
75:18 inside the very top
75:20 of the rocket in first class
75:22 with its seat belt on.
75:23 I'm in the mission
75:25 control center
75:26 here at the spaceport,
75:27 the nerve center of operations.
75:29 We're about ten kilometers
75:30 from that pad.
75:31 And behind me you can see,
75:33 it's a laser focus
75:36 here in the control center
75:38 with the mission control centers
75:40 all on console there
75:42 as we get closer to launch.
75:44 >> And let's go to black.
75:47 Take it away, Robert.
75:48 It's all yours.
75:49 >> Merry Christmas
75:50 from the Guiana Space Center
75:51 in Kourou, French Guiana.
75:53 >> You know, they do
75:54 Ariane 5 launches frequently
75:56 out of French Guiana.
75:57 But there was something
75:58 different about this one.
76:00 There was something
76:01 in the air that said
76:03 this has a different aura,
76:05 this has a different importance.
76:07 This one had
76:08 a different flavor to it,
76:09 and you knew
76:10 you were in the middle
76:11 of something big.
76:18 >> You get
76:19 the two minute warning,
76:20 everyone goes out
76:22 onto these balconies.
76:24 >> And you are watching
76:26 a number of people,
76:27 VIPs and invited guests
76:29 moving out to
76:29 the observation platform
76:31 that is right next to
76:32 the Jupiter Control Center,
76:34 as we stand by
76:36 for the one minute call
76:37 from Jean-Luc Voyer.
76:38 [ speaking French ]
76:50 >> Thumbs up from
76:51 Jean-Luc Voyer.
76:52 All systems are go.
76:53 We're inside a minute now.
76:54 T minus 50 seconds and counting.
76:56 >> And you wait,
76:57 and you can hear
76:58 a little speaker
76:59 with Rob's commentary.
77:02 >> Turbo pumps will come up
77:03 to flight speed
77:04 in seven seconds,
77:05 and the command
77:06 will be issued to ignite
77:07 the solid rocket boosters.
77:08 The James Webb Space Telescope
77:10 will be on its way.
77:15 >> And then he starts
77:16 counting down
77:18 >> T-minus 30 seconds
77:19 and counting.
77:20 >> By the time he got to eight,
77:24 my throat was just closing.
77:28 >> Standing by
77:28 for terminal count.
77:33 [ speaking French ]
77:38 [ counting down in French ]
78:16 [ cheering ]
78:17 >> Holy sh--
78:21 >> Because we were
78:22 a few miles out,
78:24 you see it go.
78:26 And it's going up
78:27 and up and up and up.
78:28 You don't hear it
78:30 for at least 45 seconds
78:32 to a minute.
78:33 You know, all of my hopes
78:35 and dreams and wishes and--
78:37 and, frankly, a piece of me
78:39 launched at that time.
78:44 And you see it go.
78:46 And it's such a strange thing
78:48 to only hear it,
78:50 and it just rumbles.
78:52 >> And liftoff.
78:53 [ speaking French ]
78:55 >> Decollage, liftoff
78:56 from a tropical rainforest
78:58 to the edge of time itself.
78:59 James Webb begins
79:01 a voyage back to
79:02 the birth of the universe.
79:05 It's a really specific,
79:08 odd rumble that a rocket has
79:10 leaving the atmosphere
79:12 that also keeps it
79:15 special in your memory,
79:16 because it's something
79:17 that is very different
79:18 than sounds that you hear
79:20 any time else.
79:21 >> Just over a minute from now,
79:22 springs will gently
79:24 push Webb away
79:25 from the upper stage
79:26 of the Ariane 5.
79:27 >> There's this loop
79:28 running in your brain
79:29 where you're like,
79:30 did that just really happen?
79:31 You know?
79:32 Did we just really take off
79:33 after multiple
79:35 decades of this?
79:36 Did we just really
79:37 leave the Earth.
79:39 >> ...Webb Space Telescope.
79:40 Go Webb!
79:41 [ cheers and applause ]
79:49 >> Ironically enough,
79:50 as we marvel on this view
79:52 from the upper stage camera,
79:53 this will be humanity's
79:54 last view of the James Webb
79:57 Space Telescope
79:58 as it moves to its workplace
79:59 about a million miles
80:01 away from Earth.
80:05 >> The launch team is done.
80:07 Now all the--
80:09 all the attention turns
80:10 to the operation centers.
80:12 >> For those of you
80:13 who are just joining us,
80:14 we are looking at
80:15 live coverage of the deployment
80:17 of the secondary mirror
80:18 for the James Webb
80:19 Space Telescope.
80:19 You're looking at
80:20 an animation that includes
80:22 real time telemetry,
80:24 real time data
80:24 from the spacecraft
80:25 as to the configuration...
80:26 >> We used to make jokes.
80:28 It was like, you know, hey,
80:29 you know, Merry Christmas.
80:30 Look what we got.
80:31 We got a telescope.
80:32 Oh, some assembly required.
80:34 Yeah, it was some assembly.
80:38 We start getting
80:39 our deployment started,
80:40 and Webb--
80:41 Webb was performing
80:43 beautifully.
80:46 >> You're seeing an animation,
80:48 but this isn't just any--
80:49 you know, any random animation.
80:51 This is actually based
80:51 on real data.
80:52 >> That script looks good.
80:54 You're go to execute.
80:56 >> Fire executing.
80:58 >> Command will fire
80:58 OTELRM group five.
81:00 [ indistinct ]
81:02 you are go to fire.
81:03 >> Copy, go to fire.
81:04 >> It's not just
81:05 pushing buttons.
81:06 There's a lot of real time
81:07 information that comes in.
81:08 And you've got to be able
81:09 to deal with it.
81:10 You've got to simulate it,
81:12 figure out what to do
81:13 and make an action.
81:14 >> I'm getting more
81:15 and more excited.
81:16 My heart is starting
81:17 to beat faster and faster.
81:18 There's-- for me
81:19 there's a tremendous
81:20 amount of joy.
81:21 I have this-this smile,
81:22 like, on my face
81:23 from ear to ear right now.
81:24 >> Again, we had
81:25 rehearsed everything
81:26 and practiced it
81:26 a zillion times,
81:27 but now you're up there.
81:28 You only got one chance
81:29 to get it right.
81:30 >> Without this mirror
81:31 in its right position,
81:32 we do not get light
81:33 into the telescope.
81:34 >> This motor move
81:34 has completed successfully
81:35 and [ indistinct ] has confirmed
81:37 we are go to proceed
81:38 with the latch two safe.
81:40 >> Roger, executing.
81:53 >> We are now at a point
81:54 where we're about 600,000
81:55 miles from Earth,
81:56 and we actually have
81:57 a telescope.
81:58 Congratulations
81:59 to everybody.
82:00 [ cheers and applause ]
82:10 >> Well, I'm thrilled to see
82:11 that it finally works,
82:12 because when we started off,
82:14 we got a lot of people
82:16 laughing at us that
82:17 that was impossibly difficult.
82:19 And now it's done.
82:55 >> Hey, John. How are you doing?
82:56 [ indistinct chatter ]
83:00 >> Hey, John. Welcome.
83:02 >> Good morning, good morning.
83:03 When we built the equipment,
83:04 we drew our requirements up,
83:05 they were all numbers.
83:06 Nobody tells you
83:08 what that means
83:09 in terms of the beauty
83:09 of the universe.
83:11 Years and years ago,
83:11 people ask me, John,
83:12 are the pictures
83:13 going to be beautiful?
83:14 And I said, yes,
83:15 but I didn't know
83:15 what they'd be like.
83:16 So it was an act of faith,
83:19 but it was a good act of faith.
83:23 >> Whatever's out there,
83:23 we're going to see it.
83:25 And we haven't cranked
83:26 this sucker up to 11,
83:27 but we're going to.
83:28 >> When things got cold enough,
83:31 the cameras worked.
83:32 I saw those first images.
83:34 I was like, yeah,
83:34 this is pretty cool.
83:36 >> We're really, you know,
83:36 standing on the backs
83:37 of thousands of people
83:38 over many,
83:40 many different disciplines
83:41 to make this happen.
83:48 >> The image came back.
83:49 It was a beautiful center image
83:52 of the star with six
83:53 radiating rays of light.
83:54 And there's supposed to be
83:55 nothing behind it, nothing.
83:59 What we saw were--
84:00 turned out to be
84:01 250-odd galaxies that have
84:03 never been seen before
84:05 in this image that supposedly
84:06 had nothing in it.
84:08 >> There are galaxies
84:09 everywhere. We were--
84:10 People said we've been
84:11 photobombed by galaxies.
84:13 So well, that's a pretty big
84:15 thrill for everybody.
84:16 [ cheers ]
84:20 >> I didn't know I was coming
84:21 to a pep rally today.
84:25 But-but that's all the better.
84:27 And you've got a-a lot
84:31 to be rallying for.
84:32 This morning,
84:34 folks across this planet
84:37 are gonna see the images
84:39 captured by this telescope,
84:41 this telescope,
84:43 because of infrared,
84:45 is going to be able to penetrate
84:47 through the dust clouds.
84:49 You're gonna see
84:50 the formation of stars.
84:52 You're gonna see
84:53 devouring black holes.
85:01 >> Here we go.
85:02 >> We're gonna-- let's do it.
85:03 >> Okay, we got
85:04 the whole world watching.
85:05 Are you ready to put
85:06 the first image up?
85:06 >> Oh, let's do it. Let's do it.
85:07 >> We are ready to see
85:09 Webb's first image
85:10 of a star dying.
85:12 A planetary nebula called
85:13 the Southern Ring.
85:16 [ gasps ]
85:18 >> Wow.
85:20 [ applause ]
85:23 [ music ]
85:46 >> The art that is out there
85:47 in the sky,
85:48 revealed for the first time.
85:49 We're thinking of the team,
85:50 and we're thanking them.
85:51 John, thanks to you.
85:52 Thanks to all of you.
85:55 [ music ]
86:07 >> I think, uh, people
86:08 brought some champagne,
86:09 so that's higher priority.
86:11 >> You're going to see things
86:12 that this species
86:13 has never seen.
86:15 And you've done it.
86:17 Tell everybody this was
86:18 an important day
86:19 in the history of humanity.
86:22 Because we will never look back.
86:23 You can never undiscover.
86:24 You can never unobserve things.
86:26 So congratulations
86:27 to the entire team.
86:29 You have all made history.
86:32 Be proud.
86:33 Thank you.
86:35 >> And, uh, you know,
86:36 I'm a scientist,
86:36 so, uh, I've been working
86:37 on this project for 20 years,
86:39 so we should expect what we saw.
86:41 But no, uh, several times
86:43 in the last six months,
86:44 I nearly break my jaw
86:46 of what I saw.
86:47 These incredible images.
86:50 >> Success is binary.
86:51 You either win or you don't.
86:53 So we built something
86:54 that was so ambitious.
86:55 If it didn't work at all,
86:57 we would be terrified.
86:58 But if it did work,
86:59 we would be guaranteed of
87:00 tremendous discoveries.
87:02 I think my favorite image
87:03 is the picture
87:04 of a cloud of galaxies
87:06 with a very, very bright one
87:07 in the center.
87:08 >> A hundred years ago,
87:09 we thought there was
87:10 only one galaxy.
87:13 Now the number is unlimited.
87:17 And that light that
87:18 you are seeing
87:19 on one of those little specks
87:22 has been traveling
87:24 for over 13 billion years.
87:27 >> Everywhere we look at
87:28 is gonna be
87:29 a scientific discovery.
87:30 Believe that.
87:31 >> Oh, no, I agree.
87:32 >> Every image is essentially
87:34 a Hubble Deep Field.
87:35 >> Yeah.
87:37 >> Is that incredible, or what?
87:38 >> It's something.
87:43 >> This stunning vista
87:45 of the cosmic cliffs
87:46 of the Carina Nebula
87:48 reveals new details about
87:50 this vast stellar nursery.
87:52 Today, for the first time,
87:54 we're seeing brand new stars
87:56 that were previously
87:57 completely hidden from our view.
88:02 >> I present to you
88:03 Maisie's Galaxy, which is
88:04 named after my daughter,
88:05 as we both discovered it
88:06 on her ninth birthday,
88:08 and she had been asking me
88:09 for months to name
88:10 a galaxy after her.
88:12 I would like to leave you
88:13 with one of my favorite images.
88:14 >> It's called Stephan's Quintet
88:17 and it's wondrous.
88:19 [ gasps ]
88:20 [ applause ]
88:24 >> The perspective of what
88:25 we're going to find out.
88:26 What do you tell
88:27 a seven-year-old when she says,
88:28 I get what the Curiosity thing
88:29 is doing, but what's JWST
88:31 gonna do, Dad?
88:33 >> Ah, okay.
88:35 Uh, she's got a good question.
88:36 What we're actually trying
88:37 to find out
88:38 is the entire history
88:39 of the universe
88:39 from then 'til now,
88:40 from the beginning 'til now,
88:41 including the things
88:42 that made galaxies and stars
88:45 and planets and Earth
88:47 and, uh, made it possible
88:48 for us to live on
88:49 our particular little Earth.
88:51 So, um, that's why
88:53 I'm interested.
88:54 I asked my dad that question,
88:55 sort of like that,
88:56 and I said, you know,
88:57 where did we come from?
88:59 I was about six or seven
89:00 or something.
89:01 Nobody knew.
89:02 We knew a little bit,
89:03 but we certainly couldn't
89:04 tell you the whole story.
89:05 >> You know, we can get as geeky
89:07 and as-as in the details
89:08 as you want,
89:09 but when you step back
89:11 for a minute, it really is
89:12 about our place in the universe.
89:14 And that's something
89:15 that resonates with people
89:16 and that they hit people
89:17 in an artistic
89:19 and a spiritual way.
89:20 >> I'm reaching out to you
89:21 from London.
89:22 >> My father was diagnosed
89:23 last year with
89:24 stage four cancer.
89:25 >> And unfortunately,
89:26 the prognosis means he doesn't
89:28 have a great deal of time
89:29 left with us.
89:30 >> From as early as I can
89:31 remember, my father has been out
89:32 burning the midnight oil,
89:34 looking at the stars
89:35 through his telescope.
89:36 >> And often driving into
89:37 the mountain overnight,
89:39 setting up to take pictures
89:40 and even submitting photos
89:42 of what he found to magazines.
89:43 >> When I was a kid,
89:44 I remember him upgrading
89:45 his telescope every few years
89:47 after saving away.
89:49 >> He is so passionate
89:50 about the work you do,
89:51 and the recent advancements
89:53 of the JWST has been
89:54 very exciting for him.
89:56 >> I'm really pleased
89:57 he's still here to follow along
89:58 with all the amazing innovation
90:00 you and your team
90:01 are doing at the moment.
90:02 >> He keeps busy
90:03 keeping up with the news
90:04 around your advancements.
90:06 Ah, that's really cool.
90:08 >> For me, these letters
90:10 express how I feel.
90:11 These letters are about
90:13 the wonder that I feel
90:15 looking at the universe,
90:16 the wonder that I feel
90:17 looking at our team
90:18 that made this observations
90:20 and tool possible.
90:22 Uh, astonishment at what
90:23 we're able to discover.
90:24 Uh, it's kind of
90:27 beyond words to describe
90:28 how satisfying and fulfilling
90:32 and rewarding it is
90:33 after reading things like this.
90:36 I mean... uh, yeah.
90:39 It's pretty hard to describe.
90:42 It really makes you feel good
90:44 about what you do.
90:45 And to make a mark
90:49 for-for good
90:51 and for positive things
90:52 in the world
90:53 is pretty, pretty cool,
90:55 pretty special.
90:56 >> That's actually why
90:57 I do love space.
90:58 And I think that other people
90:58 love space because
91:01 it does give you
91:02 that sense of awe,
91:02 and like feeling
91:03 one with the universe.
91:06 Um...
91:09 so I'm glad it helped someone.
91:12 >> Look, there aren't
91:13 many things these days
91:16 that almost everyone
91:18 on planet Earth
91:19 can feel inspired about,
91:21 but I feel like
91:22 the images from Webb
91:23 are one of those things.
91:24 They bring in
91:24 a sense of wonder.
91:26 It's kind of like
91:26 when you're a little kid
91:28 and you look up
91:28 at the night sky.
91:29 We need some wonder
91:30 in our world.
91:31 It's just a feeling of
91:33 immense joy and achievement.
91:37 And I feel happy
91:39 for humanity a little bit.
91:40 Yeah.
91:43 >> So I'm lucky enough
91:43 that I get to continue
91:45 telling the story about what
91:47 NASA's doing for its next
91:48 big flagship missions.
91:51 >> There are plenty of
91:51 other mysteries of science,
91:53 but we are seeing,
91:54 with our own eyes,
91:56 with the aid of telescopes,
91:58 the process unfolding.
91:59 So what more could you
92:01 hope for from astronomy?
92:02 >> One of the core obligations
92:05 we have is oversight,
92:07 and we quite often
92:08 hear in government
92:09 how things don't work.
92:10 I just want to say
92:11 thank you for exceeding
92:13 our expectations,
92:15 and let's continue on with that.
92:16 I yield back.
92:17 >> So, congratulations
92:19 to everyone, uh,
92:20 for making it happen.
92:21 And we now are counting
92:22 on continued brilliance
92:23 for the next half a century,
92:25 at least.
92:26 Thank you for proving
92:27 it's possible.
92:28 Looking back to childhood,
92:30 we had no idea...
92:33 no one had any idea
92:34 what the future would bring
92:36 in terms of space exploration,
92:38 new technology, electronics.
92:40 It was all new.
92:41 We had no idea that computers
92:42 would ever be so powerful,
92:44 or so common.
92:46 Marvels are yet to occur,
92:47 and we are still
92:48 growing rapidly
92:49 in our capabilities.
92:51 So astronomers have already
92:53 had a book that we outlined
92:55 what we'd like to do
92:56 for the next many decades.
92:57 I think it'll take us a century
92:59 before we run out of that book.
93:01 And then,
93:02 from what we learn
93:03 in the next decades,
93:04 we'll have more miracles
93:05 to produce,
93:06 more miracles to ask for.
93:08 So, much is possible.
93:10 And this is
93:11 a very exciting time
93:12 to be an astronomer.
93:33 >> I get to see things
93:35 that are way beyond Earth
93:36 because of where I work.
93:39 >> That will surely surprise us
93:40 in some way that
93:41 I can't tell you.
93:43 >> It's an exciting moment.
93:44 This thing's been
93:45 a long time in the making.
93:46 >> And once we get it out there,
93:47 we got to robotically
93:49 put it back together.
93:50 That's never been done before.
93:52 >> A pride in humanity
93:53 that when we want to,
93:55 we can do that.
93:56 >> We're building this telescope
93:57 really to answer
93:58 fundamental questions
94:00 that we have.
94:01 >>It's detecting the building
94:02 blocks of life on exoplanets.
94:05 >> That then gets sent
94:06 into the telescope.
94:08 >> All of these galaxies
94:09 in the background photobomb
94:10 the pictures, right?
94:12 >> I feel like we're discovering
94:12 new parts of the universe.
94:14 >> It's going to, uh,
94:14 inspire us as people.
94:16 We're going to solve a problem
94:17 we didn't know how to solve,
94:18 because we're gonna learn
94:19 something that we didn't know
94:20 until this big eyeball
94:22 in the sky...
94:23 opened up and saw it.
94:25 I don't know who else
94:26 gets to say that.
94:31 >> The James Webb
94:32 Space Telescope
94:33 is the most ambitious
94:34 and complex space
94:35 science mission
94:36 humanity's ever undertaken.
94:38 >> No one's ever done
94:39 anything like this before,
94:41 but the science
94:41 will be worth the wait.
94:44 >> Roger all, Discovery.
94:47 [ music ]
95:17 [ music ]
95:46 >> Researchers were astonished
95:47 to see the dust cloud
95:48 annihilated when
95:49 the massive stars exploded.
95:52 [ music ]
95:58 >> Now Webb takes us even deeper
96:00 into the infrared universe.
96:04 [ music ]
96:34 [ music ]
