WEBVTT FILE 1 00:00:01.020 --> 00:00:06.020 This is your telescope. 2 00:00:06.020 --> 00:00:11.020 An engineering marvel. An exploration powerhouse. 3 00:00:11.020 --> 00:00:16.020 Use it to look back in time and explore the first galaxies that 4 00:00:16.020 --> 00:00:21.020 formed after the Big Bang; to peer into atmospheres of planets orbiting 5 00:00:21.020 --> 00:00:26.020 distant stars. It’s your eye-piece to the uncharted, unknown and unimagined. 6 00:00:26.020 --> 00:00:31.020 7 00:00:31.020 --> 00:00:36.020 This is the largest, most complex and challenging 8 00:00:36.020 --> 00:00:41.020 space telescope ever constructed. It will change our understanding of 9 00:00:41.020 --> 00:00:46.020 the universe and our place in it. The James Webb Space Telescope. 10 00:00:46.020 --> 00:00:51.020 11 00:00:51.020 --> 00:00:56.020 music 12 00:00:56.020 --> 00:01:01.020 Equipped with the largest primary mirror ever to be flown in space; at 6 and a half meters, 13 00:01:01.020 --> 00:01:06.020 it’s more than 6 times the size of the Hubble Space Telescope primary mirror. 14 00:01:06.020 --> 00:01:11.020 Webb’s four, cutting-edge, infrared 15 00:01:11.020 --> 00:01:16.020 instruments and cameras operate at super cold temperatures; 16 00:01:16.020 --> 00:01:21.020 temperatures colder than the surface of Pluto. 17 00:01:21.020 --> 00:01:26.020 Getting this cold is done with the help of the largest sunshield ever 18 00:01:26.020 --> 00:01:31.020 flown; a 5-layer, tennis court-size sunshield that blocks heat 19 00:01:31.020 --> 00:01:36.020 from the Sun, Earth and Moon. 20 00:01:36.020 --> 00:01:41.020 21 00:01:41.020 --> 00:01:46.020 Webb will be the first telescope to detect light from the most distant galaxies in the Universe. 22 00:01:46.020 --> 00:01:51.020 These first galaxies formed about 13.5 billion years ago, 23 00:01:51.020 --> 00:01:56.020 only 300 or so million years after the Big Bang. Webb carries 24 00:01:56.020 --> 00:02:01.020 advanced technologies to tackle some of the most fundamental questions about the Universe. 25 00:02:01.020 --> 00:02:06.020 How did the first galaxies form and evolve? Are there 26 00:02:06.020 --> 00:02:11.020 chemical signatures of the building-blocks of life on other worlds? 27 00:02:11.020 --> 00:02:16.020 Is our solar system unique? 28 00:02:16.020 --> 00:02:21.020 Launching such a large telescope into space is an incredible engineering challenge. 29 00:02:21.020 --> 00:02:26.020 Fully deployed, Webb is too large to fit inside any rocket fairing. 30 00:02:26.020 --> 00:02:31.020 Engineers designed it to be folded, like origami, to 31 00:02:31.020 --> 00:02:36.020 squeeze inside the European Space Agency’s 5-meter diameter, Ariane 5 rocket fairing. 32 00:02:36.020 --> 00:02:41.020 After launch, controllers on the ground deploy Webb remotely. 33 00:02:41.020 --> 00:02:46.020 34 00:02:46.020 --> 00:02:51.020 Deployment is an intricate ballet. For nearly 3-weeks, controllers carefully unfold Webb. 35 00:02:51.020 --> 00:02:56.020 After this delicate dance, Webb’s golden mirrors are precisely 36 00:02:56.020 --> 00:03:01.020 aligned using motors behind each hexagonal mirror segment, adjusting them 37 00:03:01.020 --> 00:03:06.020 to form one, perfect mirror. Once the instruments are 38 00:03:06.020 --> 00:03:11.020 cooled, the exploration will begin. Webb is a 39 00:03:11.020 --> 00:03:16.000 technological challenge like no other. Born of the efforts of thousands of people 40 00:03:16.000 --> 00:03:21.000 across the United States, Canada and Europe. The James Webb 41 00:03:21.000 --> 00:03:26.000 Space Telescope is your telescope. Use it to explore. 42 00:03:26.000 --> 00:03:31.020 To challenge theories. To see sights yet unseen. It’s yours 43 00:03:31.020 --> 00:03:36.020 to unfold the beauty and mystery in the Universe, and 44 00:03:36.020 --> 00:03:44.341 our place in it.
