Transcript
00:00 It's 900 degrees hot at the surface, has powerful high altitude winds, and is blanketed by a
00:08 dense carbon dioxide atmosphere.
00:11 The planet Venus.
00:12 Although the same size and density as Earth, the similarities end there.
00:17 Earth has water and light.
00:19 Venus is desolate, dry, apparently lightless.
00:22 The DAVINCI mission, named after Leonardo da Vinci, will now take us back to Venus and
00:36 address unresolved questions about this mysterious planet.
00:40 This exciting new mission will launch in June 2029.
00:44 During two Gravity Assist flybys, da Vinci will study the cloud tops in ultraviolet light,
00:50 tracking cloud motions and analyzing mysterious ultraviolet absorbing chemicals.
00:56 Both flybys will also examine nightside heat emanating from the surface.
01:01 These geological clues will paint a global picture of surface composition and its evolution.
01:07 Seven months after our second flyby, da Vinci will release its atmospheric descent probe,
01:13 which will enter the atmosphere over the course of two days.
01:16 The probe will take about an hour to fall through the atmosphere, taking measurements
01:20 down to the surface.
01:22 These measurements will include profiles of composition, winds, temperature, pressure,
01:28 and acceleration.
01:30 Key gases will help us understand how Venus formed and evolved.
01:34 Some of these measurements may even reveal signatures of ancient water.
01:39 The spherical probe houses the state-of-the-art instruments that will work together to address
01:45 questions about the Venus atmosphere, protecting them from the extreme temperatures, high pressures,
01:51 and acidic clouds in the environment.
01:53 Da Vinci's camera peers down through a small viewing port, and once the probe passes below
01:58 the clouds, it will start to collect a series of three-dimensional views that will also
02:03 help us understand whether the rocks of the Alpha Regi Ohio region reveal a story of an
02:09 ancient continent shaped by water.
02:12 And an oxygen-sensing student collaboration experiment will reveal the role of this gas
02:17 in the deep atmosphere.
02:19 The discoveries that emerge from this diverse dataset will help tell us whether Venus was
02:24 once habitable.
02:26 And the story that we reveal will reach even beyond our solar system to analog exoplanets
02:32 that will be observed with the James Webb Space Telescope.
02:37 Venus is waiting for us all, and Da Vinci is ready to take us there and ignite a new
02:43 Venus renaissance.
