1 00:00:00,613 --> 00:00:05,051 As a kid, I was fascinated with all things air and space. 2 00:00:05,051 --> 00:00:07,592 I would watch Nova on PBS. 3 00:00:07,592 --> 00:00:10,545 Our school would show Bill Nye the Science Guy. 4 00:00:10,545 --> 00:00:14,670 When I was in elementary school, my next door neighbor, 5 00:00:14,670 --> 00:00:16,520 he gave me a book for my birthday. 6 00:00:16,520 --> 00:00:17,689 It was an astronomy book, 7 00:00:17,689 --> 00:00:20,641 and I poured over that thing for hours on end, 8 00:00:20,641 --> 00:00:23,241 and it was a combination of all these things 9 00:00:23,241 --> 00:00:26,909 that inspired me to pursue space exploration 10 00:00:26,909 --> 00:00:31,377 as my own personal dream, and part of that dream was, 11 00:00:31,377 --> 00:00:33,986 I always wanted to just fly around the solar system 12 00:00:33,986 --> 00:00:37,383 and visit different planets and visit moons and spacecraft. 13 00:00:37,383 --> 00:00:42,077 Well, a number of years later, I graduated from UCLA 14 00:00:42,077 --> 00:00:44,259 and I found myself at NASA, 15 00:00:44,259 --> 00:00:46,363 working for the jet propulsion laboratory, 16 00:00:46,363 --> 00:00:49,058 and there our team was challenged 17 00:00:49,058 --> 00:00:53,447 to create a 3D visualization of the solar system, 18 00:00:53,447 --> 00:00:57,321 and today I want to show you what we've done so far. 19 00:00:57,321 --> 00:01:00,707 Now, the kicker is, everything I'm about to do here 20 00:01:00,707 --> 00:01:04,513 you can do at home, because we built this 21 00:01:04,513 --> 00:01:07,323 for the public for you guys to use. 22 00:01:07,323 --> 00:01:09,244 So what you're looking at right now is the Earth. 23 00:01:09,244 --> 00:01:11,215 You can see the United States and California 24 00:01:11,215 --> 00:01:13,994 and San Diego, and you can use the mouse 25 00:01:13,994 --> 00:01:16,049 or the keyboard to spin things around. 26 00:01:16,049 --> 00:01:19,488 Now, this isn't new. Anyone who's used Google Earth 27 00:01:19,488 --> 00:01:22,499 has seen this before, but one thing we like to say 28 00:01:22,499 --> 00:01:26,312 in our group is, we do the opposite of Google Earth. 29 00:01:26,312 --> 00:01:30,361 Google Earth goes from this view down to your backyard. 30 00:01:30,361 --> 00:01:33,894 We go from this view out to the stars. 31 00:01:33,894 --> 00:01:36,821 So the Earth is cool, but what we really want to show 32 00:01:36,821 --> 00:01:38,687 are the spacecraft, 33 00:01:38,687 --> 00:01:41,432 so I'm going to bring the interface back up, 34 00:01:41,432 --> 00:01:44,154 and now you're looking at a number of satellites 35 00:01:44,154 --> 00:01:45,091 orbiting the Earth. 36 00:01:45,091 --> 00:01:48,373 These are a number of our science space Earth orbiters. 37 00:01:48,373 --> 00:01:50,691 We haven't included military satellites and weather satellites 38 00:01:50,691 --> 00:01:52,704 and communication satellites and reconnaissance satellites. 39 00:01:52,704 --> 00:01:55,203 If we did, it would be a complete mess, 40 00:01:55,203 --> 00:01:57,259 because there's a lot of stuff out there. 41 00:01:57,259 --> 00:02:01,064 And the cool thing is, we actually created 3D models 42 00:02:01,064 --> 00:02:04,329 for a number of these spacecraft, so if you want to visit 43 00:02:04,329 --> 00:02:07,355 any of these, all you need to do is double-click on them. 44 00:02:07,355 --> 00:02:10,591 So I'm going to find the International Space Station, 45 00:02:10,591 --> 00:02:15,598 double-click, and it will take us all the way down to the ISS. 46 00:02:15,598 --> 00:02:18,207 And now you're riding along with the ISS 47 00:02:18,207 --> 00:02:21,402 where it is right now. 48 00:02:21,402 --> 00:02:23,194 And the other cool thing is, not only can we 49 00:02:23,194 --> 00:02:26,469 move the camera around, we can also control time, 50 00:02:26,469 --> 00:02:28,582 so I can slide this jog dial here 51 00:02:28,582 --> 00:02:30,877 to shuttle time forward, and now 52 00:02:30,877 --> 00:02:35,310 we can see what a sunset on the ISS would look like, 53 00:02:35,310 --> 00:02:40,763 and they get one every 90 minutes. (Laughter) 54 00:02:40,763 --> 00:02:43,346 All right, so what about the rest of it? 55 00:02:43,346 --> 00:02:45,987 Well, I can click on this home button over here, 56 00:02:45,987 --> 00:02:48,954 and that will take us up to the inner solar system, 57 00:02:48,954 --> 00:02:51,081 and now we're looking at the rest of the solar system. 58 00:02:51,081 --> 00:02:53,624 You can see, there's Saturn, there's Jupiter, 59 00:02:53,624 --> 00:02:56,740 and while we're here, I want to point out something. 60 00:02:56,740 --> 00:02:59,297 It's actually pretty busy. 61 00:02:59,297 --> 00:03:01,386 Here we have the Mars Science Laboratory 62 00:03:01,386 --> 00:03:03,929 on its way to Mars, just launched last weekend. 63 00:03:03,929 --> 00:03:07,911 Here we have Juno on its cruise to Jupiter, there. 64 00:03:07,911 --> 00:03:09,873 We have Dawn orbiting Vesta, 65 00:03:09,873 --> 00:03:11,883 and we have over here New Horizons 66 00:03:11,883 --> 00:03:14,341 on a straight shot to Pluto. 67 00:03:14,341 --> 00:03:16,296 And I mention this because 68 00:03:16,296 --> 00:03:19,101 there's this strange public perception that 69 00:03:19,101 --> 00:03:21,894 NASA's dead, that the space shuttles stopped flying 70 00:03:21,894 --> 00:03:24,478 and all of the sudden there's no more spacecraft out there. 71 00:03:24,478 --> 00:03:29,057 Well, a lot of what NASA does is robotic exploration, 72 00:03:29,057 --> 00:03:31,656 and we have a lot of spacecraft out there. 73 00:03:31,656 --> 00:03:33,929 Granted, we're not sending humans up at the moment, 74 00:03:33,929 --> 00:03:36,736 well at least with our own launch vehicles, 75 00:03:36,736 --> 00:03:38,980 but NASA is far from dead, 76 00:03:38,980 --> 00:03:42,310 and one of the reasons why we write a program like this 77 00:03:42,310 --> 00:03:44,797 is so that people realize that there's so many other things 78 00:03:44,797 --> 00:03:46,488 that we're doing. 79 00:03:46,488 --> 00:03:48,210 Anyway, while we're here, again, 80 00:03:48,210 --> 00:03:50,140 if you want to visit anything, 81 00:03:50,140 --> 00:03:52,057 all you need to do is double-click. 82 00:03:52,057 --> 00:03:54,627 So I'm just going to double-click on Vesta, 83 00:03:54,627 --> 00:03:58,721 and here we have Dawn orbiting Vesta, 84 00:03:58,721 --> 00:04:00,911 and this is happening right now. 85 00:04:00,911 --> 00:04:05,118 I'm going to double-click on Uranus, and we can see 86 00:04:05,118 --> 00:04:08,426 Uranus rotating on its side along with its moons. 87 00:04:08,426 --> 00:04:12,218 You can see how it's tilted at about 89 degrees. 88 00:04:12,218 --> 00:04:16,178 And just being able to visit different places 89 00:04:16,178 --> 00:04:17,464 and go through different times, 90 00:04:17,464 --> 00:04:20,559 we have data from 1950 to 2050. 91 00:04:20,559 --> 00:04:22,776 Granted, we don't have everything in between, 92 00:04:22,776 --> 00:04:24,542 because some of the data is hard to get. 93 00:04:24,542 --> 00:04:28,457 Just being able to visit places in different times, 94 00:04:28,457 --> 00:04:32,125 you can explore this for hours, 95 00:04:32,125 --> 00:04:34,081 literally hours on end, 96 00:04:34,081 --> 00:04:36,959 but I want to show you one thing in particular, 97 00:04:36,959 --> 00:04:39,344 so I'm going to open up the destination tab, 98 00:04:39,344 --> 00:04:42,731 spacecraft outer planet missions, Voyager 1, 99 00:04:42,731 --> 00:04:45,731 and I'm going to bring up the Titan flyby. 100 00:04:45,731 --> 00:04:48,521 So now we've gone back in time. 101 00:04:48,521 --> 00:04:51,458 We're now riding along with Voyager 1. 102 00:04:51,458 --> 00:04:54,855 The date here is November 11, 1980. 103 00:04:54,855 --> 00:04:57,184 Now, there's a funny thing going on here. 104 00:04:57,184 --> 00:04:59,377 It doesn't look like anything's going on. 105 00:04:59,377 --> 00:05:01,477 It looks like I've paused the program. 106 00:05:01,477 --> 00:05:03,503 It's actually running at real rate right now, 107 00:05:03,503 --> 00:05:05,503 one second per second, and in fact, 108 00:05:05,503 --> 00:05:09,061 Voyager 1 here is flying by Titan at 109 00:05:09,061 --> 00:05:13,171 I think it's 38,000 miles per hour. 110 00:05:13,171 --> 00:05:15,874 It only looks like nothing's moving because, well, 111 00:05:15,874 --> 00:05:18,680 Saturn here is 700,000 miles away, 112 00:05:18,680 --> 00:05:21,522 and Titan here is 4,000 to 5,000 miles away. 113 00:05:21,522 --> 00:05:25,607 It's just the vastness of space makes it look like nothing's happening. 114 00:05:25,607 --> 00:05:27,485 But to make it more interesting, 115 00:05:27,485 --> 00:05:30,331 I'm going to speed up time, and we can watch 116 00:05:30,331 --> 00:05:32,986 as Voyager 1 flies by Titan, 117 00:05:32,986 --> 00:05:35,201 which is a hazy moon of Saturn. 118 00:05:35,201 --> 00:05:37,505 It actually has a very thick atmosphere. 119 00:05:37,505 --> 00:05:40,766 And I'm going to recenter the camera on Saturn, here. 120 00:05:40,766 --> 00:05:44,655 I'm going to pull out, and I want to show you 121 00:05:44,655 --> 00:05:47,885 Voyager 1 as it flies by Saturn. 122 00:05:47,885 --> 00:05:50,135 There's a point to be made here. 123 00:05:50,135 --> 00:05:52,777 With a 3D visualization like this, 124 00:05:52,777 --> 00:05:56,558 we can not only just say Voyager 1 flew by Saturn. 125 00:05:56,558 --> 00:05:58,180 There's a whole story to tell here. 126 00:05:58,180 --> 00:06:01,036 And even better, because it's an interactive application, 127 00:06:01,036 --> 00:06:03,016 you can tell the story for yourself. 128 00:06:03,016 --> 00:06:05,221 If you want to pause it, you can pause it. 129 00:06:05,221 --> 00:06:06,708 If you want to keep going, if you want to change 130 00:06:06,708 --> 00:06:09,032 the camera angle, you can do that, 131 00:06:09,032 --> 00:06:11,555 and because of that, I can show you 132 00:06:11,555 --> 00:06:14,376 that Voyager 1 doesn't just fly by Saturn. 133 00:06:14,376 --> 00:06:18,355 It actually flies underneath Saturn. 134 00:06:18,355 --> 00:06:21,725 Now, what happens is, as it flies underneath Saturn, 135 00:06:21,725 --> 00:06:24,636 Saturn grabs it gravitationally and flings it up 136 00:06:24,636 --> 00:06:26,926 and out of the solar system, 137 00:06:26,926 --> 00:06:29,964 so if I just keep letting this go, 138 00:06:29,964 --> 00:06:34,621 you can see Voyager 1 fly up like that. 139 00:06:34,621 --> 00:06:36,753 And, in fact, I'm going to go back to the solar system. 140 00:06:36,753 --> 00:06:39,661 I'm going to go back to today, now, 141 00:06:39,661 --> 00:06:43,307 and I want to show you where Voyager 1 is. 142 00:06:43,307 --> 00:06:47,910 Right there, above, way above the solar system, 143 00:06:47,910 --> 00:06:50,450 way beyond our solar system. 144 00:06:50,450 --> 00:06:53,037 And here's the thing. Now you know how it got there. 145 00:06:53,037 --> 00:06:54,665 Now you know why, and to me, 146 00:06:54,665 --> 00:06:56,453 that's the point of this program. 147 00:06:56,453 --> 00:06:59,726 You can manipulate it yourself. 148 00:06:59,726 --> 00:07:03,022 You can fly around yourself and you can learn for yourself. 149 00:07:03,022 --> 00:07:06,513 You know, the theme today is "The World In Your Grasp." 150 00:07:06,513 --> 00:07:07,935 Well, we're trying to give you 151 00:07:07,935 --> 00:07:09,532 the solar system in your grasp — (Laughter) — 152 00:07:09,532 --> 00:07:11,081 and we hope once it's there, 153 00:07:11,081 --> 00:07:13,334 you'll be able to learn for yourself 154 00:07:13,334 --> 00:07:15,528 what we've done out there, and what we're about to do. 155 00:07:15,528 --> 00:07:19,027 And my personal dream is for kids to take this 156 00:07:19,027 --> 00:07:21,712 and explore and see the wonders out there 157 00:07:21,712 --> 00:07:24,721 and be inspired, as I was as a kid, 158 00:07:24,721 --> 00:07:26,279 to pursue STEM education 159 00:07:26,279 --> 00:07:29,029 and to pursue a dream in space exploration. 160 00:07:29,029 --> 00:07:32,251 Thank you. (Applause)
