WEBVTT FILE 1 00:00:00.000 --> 00:00:03.689 Venus, our next frontier here at the 2 00:00:03.689 --> 00:00:05.250 Goddard Space Flight Center looking with 3 00:00:05.250 --> 00:00:07.230 Wallops we have simulated what it would 4 00:00:07.230 --> 00:00:09.780 be like to freefall descent to the 5 00:00:09.780 --> 00:00:12.000 surface of Venus with cameras that would 6 00:00:12.000 --> 00:00:14.309 allow us to see the surface from above 7 00:00:14.309 --> 00:00:16.500 for the first time in human history at 8 00:00:16.500 --> 00:00:18.840 scales that are similar to those we 9 00:00:18.840 --> 00:00:21.960 experience as we land in aircraft at 10 00:00:21.960 --> 00:00:23.730 airports here on earth and these images 11 00:00:23.730 --> 00:00:26.130 are synthetic images but actually made 12 00:00:26.130 --> 00:00:27.960 from our helicopter experiment to show 13 00:00:27.960 --> 00:00:29.820 what landscapes on Venus would look like 14 00:00:29.820 --> 00:00:32.309 if a future prober Lander were to go 15 00:00:32.309 --> 00:00:35.520 there we want to use these images to 16 00:00:35.520 --> 00:00:37.739 allow us to reconstruct what the 17 00:00:37.739 --> 00:00:40.110 landscapes of this this crazy planet are 18 00:00:40.110 --> 00:00:41.820 like so using the Wallops Flight 19 00:00:41.820 --> 00:00:43.860 Facility helicopter equipped with 20 00:00:43.860 --> 00:00:45.989 cameras viewing it nadir we simulated 21 00:00:45.989 --> 00:00:47.820 the final 2,000 meters of descent on 22 00:00:47.820 --> 00:00:50.670 Venus over a rugged quarry system with 23 00:00:50.670 --> 00:00:52.500 landscapes that are similar to those we 24 00:00:52.500 --> 00:00:54.899 find on planets like Mars and Venus and 25 00:00:54.899 --> 00:00:57.329 using a camera system like those that 26 00:00:57.329 --> 00:00:59.730 could be carried on probes we image the 27 00:00:59.730 --> 00:01:01.980 sands and the gravels and the boulders 28 00:01:01.980 --> 00:01:04.589 and the other textures that we found on 29 00:01:04.589 --> 00:01:06.630 planets as we descend it here you can 30 00:01:06.630 --> 00:01:09.060 see the rugged boulders that some of us 31 00:01:09.060 --> 00:01:11.250 feel might exist in the highlands of 32 00:01:11.250 --> 00:01:13.799 Venus we also see fields of gravels and 33 00:01:13.799 --> 00:01:16.590 conical hills that remind us of small 34 00:01:16.590 --> 00:01:19.080 volcanoes these images are collected at 35 00:01:19.080 --> 00:01:21.509 meter resolution and finer from a camera 36 00:01:21.509 --> 00:01:23.580 pointing straight down as we descend at 37 00:01:23.580 --> 00:01:25.740 about 10 meters a second to the surface 38 00:01:25.740 --> 00:01:28.170 of Venus and by taking these pictures 39 00:01:28.170 --> 00:01:29.549 and using structure from motion 40 00:01:29.549 --> 00:01:32.400 algorithms we can put them together to 41 00:01:32.400 --> 00:01:35.729 form the first ever topographic models 42 00:01:35.729 --> 00:01:37.619 of the surface of another world from 43 00:01:37.619 --> 00:01:40.049 landing and these models constructed 44 00:01:40.049 --> 00:01:42.720 from small numbers of images look like 45 00:01:42.720 --> 00:01:45.180 this colored maps of what's high and 46 00:01:45.180 --> 00:01:47.670 what slow these relief features allow us 47 00:01:47.670 --> 00:01:49.560 to depict the landscapes quantitatively 48 00:01:49.560 --> 00:01:52.380 to model their origin what's been going 49 00:01:52.380 --> 00:01:54.630 on here you see a conical Hill of gravel 50 00:01:54.630 --> 00:01:56.610 shown in yellows and greens and blues 51 00:01:56.610 --> 00:01:59.219 against a backdrop of a smooth plain we 52 00:01:59.219 --> 00:02:00.719 could see landscapes like this in the 53 00:02:00.719 --> 00:02:02.520 highlands of Venus and this is the 54 00:02:02.520 --> 00:02:04.380 quality of topography we could produce 55 00:02:04.380 --> 00:02:07.500 on any future probe or lander to Venus 56 00:02:07.500 --> 00:02:09.390 and we believe this is important for 57 00:02:09.390 --> 00:02:11.250 untangling the history of our sister 58 00:02:11.250 --> 00:02:13.590 planet and by putting the images to 59 00:02:13.590 --> 00:02:15.599 other with the topography we can make 60 00:02:15.599 --> 00:02:17.879 perspective views synthesize the views 61 00:02:17.879 --> 00:02:19.950 that we might see at the ground or as we 62 00:02:19.950 --> 00:02:22.410 climb into these hills so the team at 63 00:02:22.410 --> 00:02:24.510 Goddard Space Flight Center and Wallops 64 00:02:24.510 --> 00:02:26.220 Flight Facility conducted this 65 00:02:26.220 --> 00:02:28.349 experiment to stimulate the future 66 00:02:28.349 --> 00:02:30.540 exploration of the planet Venus in the 67 00:02:30.540 --> 00:02:33.720 2020s and beyond with a vision of using 68 00:02:33.720 --> 00:02:36.390 our eyes wide open as we descend in a 69 00:02:36.390 --> 00:02:39.959 freefall geometry to see Venus in 3d our 70 00:02:39.959 --> 00:02:42.930 next stop we believe is Venus the lost 71 00:02:42.930 --> 00:02:45.680 ocean world...
