WEBVTT FILE 1 00:00:02.002 --> 00:00:03.803 It's 900 degrees hot at the 2 00:00:03.803 --> 00:00:06.773 surface, has powerful high altitude winds, 3 00:00:06.973 --> 00:00:10.143 and is blanketed by a dense carbon dioxide atmosphere. 4 00:00:10.944 --> 00:00:13.880 The planet Venus, although the same size 5 00:00:13.880 --> 00:00:17.050 and density as Earth, the similarities end there. 6 00:00:17.050 --> 00:00:18.718 Earth has water and life. 7 00:00:18.718 --> 00:00:19.219 Venus is desolate, 8 00:00:20.920 --> 00:00:24.657 dry, apparently lifeless. 9 00:00:30.897 --> 00:00:32.132 The DAVINCI mission 10 00:00:32.132 --> 00:00:36.069 named after Leonardo da Vinci will now take us back to Venus 11 00:00:36.069 --> 00:00:39.873 and address unresolved questions about this mysterious planet. 12 00:00:40.507 --> 00:00:44.344 This exciting new mission will launch in June 2029. 13 00:00:44.377 --> 00:00:48.782 During two gravity assist flybys, DAVINCI will study the cloud tops 14 00:00:48.782 --> 00:00:52.652 in ultraviolet light, tracking cloud motions and analyzing 15 00:00:52.652 --> 00:00:55.922 mysterious ultraviolet absorbing chemicals. 16 00:00:56.456 --> 00:01:01.294 Both flybys will also examine nightside heat emanating from the surface. 17 00:01:01.561 --> 00:01:05.665 These geological clues will paint a global picture of surface 18 00:01:05.665 --> 00:01:07.967 composition and its evolution. 19 00:01:07.967 --> 00:01:12.238 Seven months after our second flyby, DAVINCI will release its atmospheric 20 00:01:12.238 --> 00:01:16.309 descent probe, which will enter the atmosphere over the course of two days. 21 00:01:16.709 --> 00:01:18.511 The probe will take about an hour 22 00:01:18.511 --> 00:01:22.082 to fall through the atmosphere, taking measurements down to the surface. 23 00:01:22.615 --> 00:01:25.885 These measurements will include profiles of composition, 24 00:01:25.885 --> 00:01:29.456 winds, temperature pressure and acceleration. 25 00:01:29.989 --> 00:01:34.227 Key gases will help us understand how Venus formed and evolved. 26 00:01:34.561 --> 00:01:39.532 Some of these measurements may even reveal signatures of ancient water. 27 00:01:39.933 --> 00:01:43.803 The spherical probe houses the state of the art instruments 28 00:01:43.870 --> 00:01:47.774 that will work together to address questions about the Venus atmosphere, 29 00:01:47.774 --> 00:01:50.443 protecting them from the extreme temperatures, 30 00:01:50.443 --> 00:01:53.379 high pressures and acidic clouds in the environment. 31 00:01:53.613 --> 00:01:57.050 DAVINCI’s camera peers down through a small viewing port, 32 00:01:57.150 --> 00:02:00.787 and once the probe passes below the clouds, it will start to collect 33 00:02:00.787 --> 00:02:04.958 a series of three dimensional views that will also help us understand 34 00:02:04.958 --> 00:02:08.795 whether the rocks of the Alpha Regio Highland region reveal 35 00:02:08.795 --> 00:02:13.233 a story of an ancient continent shaped by water and an oxygen 36 00:02:13.233 --> 00:02:14.767 sensing student collaboration 37 00:02:14.767 --> 00:02:18.872 experiment will reveal the role of this gas in the deep atmosphere. 38 00:02:18.972 --> 00:02:22.709 The discoveries that emerge from this diverse dataset, will help 39 00:02:22.709 --> 00:02:25.345 tell us whether Venus was once habitable 40 00:02:25.812 --> 00:02:30.750 and the story that we reveal will reach even beyond our solar system 41 00:02:30.950 --> 00:02:34.020 to analog exoplanets that will be observed 42 00:02:34.020 --> 00:02:36.222 with the James Webb Space Telescope. 43 00:02:37.023 --> 00:02:39.192 Venus is waiting for us all 44 00:02:39.325 --> 00:02:44.397 and DAVINCI is ready to take us there and ignite a new Venus renaissance.
