0:00:00.613,0:00:05.051 As a kid, I was fascinated with all things air and space. 0:00:05.051,0:00:07.592 I would watch Nova on PBS. 0:00:07.592,0:00:10.545 Our school would show Bill Nye the Science Guy. 0:00:10.545,0:00:14.670 When I was in elementary school, my next door neighbor, 0:00:14.670,0:00:16.520 he gave me a book for my birthday. 0:00:16.520,0:00:17.689 It was an astronomy book, 0:00:17.689,0:00:20.641 and I poured over that thing for hours on end, 0:00:20.641,0:00:23.241 and it was a combination of all these things 0:00:23.241,0:00:26.909 that inspired me to pursue space exploration 0:00:26.909,0:00:31.377 as my own personal dream, and part of that dream was, 0:00:31.377,0:00:33.986 I always wanted to just fly around the solar system 0:00:33.986,0:00:37.383 and visit different planets and visit moons and spacecraft. 0:00:37.383,0:00:42.077 Well, a number of years later, I graduated from UCLA 0:00:42.077,0:00:44.259 and I found myself at NASA, 0:00:44.259,0:00:46.363 working for the jet propulsion laboratory, 0:00:46.363,0:00:49.058 and there our team was challenged 0:00:49.058,0:00:53.447 to create a 3D visualization of the solar system, 0:00:53.447,0:00:57.321 and today I want to show you what we've done so far. 0:00:57.321,0:01:00.707 Now, the kicker is, everything I'm about to do here 0:01:00.707,0:01:04.513 you can do at home, because we built this 0:01:04.513,0:01:07.323 for the public for you guys to use. 0:01:07.323,0:01:09.244 So what you're looking at right now is the Earth. 0:01:09.244,0:01:11.215 You can see the United States and California 0:01:11.215,0:01:13.994 and San Diego, and you can use the mouse 0:01:13.994,0:01:16.049 or the keyboard to spin things around. 0:01:16.049,0:01:19.488 Now, this isn't new. Anyone who's used Google Earth 0:01:19.488,0:01:22.499 has seen this before, but one thing we like to say 0:01:22.499,0:01:26.312 in our group is, we do the opposite of Google Earth. 0:01:26.312,0:01:30.361 Google Earth goes from this view down to your backyard. 0:01:30.361,0:01:33.894 We go from this view out to the stars. 0:01:33.894,0:01:36.821 So the Earth is cool, but what we really want to show 0:01:36.821,0:01:38.687 are the spacecraft, 0:01:38.687,0:01:41.432 so I'm going to bring the interface back up, 0:01:41.432,0:01:44.154 and now you're looking at a number of satellites 0:01:44.154,0:01:45.091 orbiting the Earth. 0:01:45.091,0:01:48.373 These are a number of our science space Earth orbiters. 0:01:48.373,0:01:50.691 We haven't included military satellites and weather satellites 0:01:50.691,0:01:52.704 and communication satellites and reconnaissance satellites. 0:01:52.704,0:01:55.203 If we did, it would be a complete mess, 0:01:55.203,0:01:57.259 because there's a lot of stuff out there. 0:01:57.259,0:02:01.064 And the cool thing is, we actually created 3D models 0:02:01.064,0:02:04.329 for a number of these spacecraft, so if you want to visit 0:02:04.329,0:02:07.355 any of these, all you need to do is double-click on them. 0:02:07.355,0:02:10.591 So I'm going to find the International Space Station, 0:02:10.591,0:02:15.598 double-click, and it will take us all the way down to the ISS. 0:02:15.598,0:02:18.207 And now you're riding along with the ISS 0:02:18.207,0:02:21.402 where it is right now. 0:02:21.402,0:02:23.194 And the other cool thing is, not only can we 0:02:23.194,0:02:26.469 move the camera around, we can also control time, 0:02:26.469,0:02:28.582 so I can slide this jog dial here 0:02:28.582,0:02:30.877 to shuttle time forward, and now 0:02:30.877,0:02:35.310 we can see what a sunset on the ISS would look like, 0:02:35.310,0:02:40.763 and they get one every 90 minutes. (Laughter) 0:02:40.763,0:02:43.346 All right, so what about the rest of it? 0:02:43.346,0:02:45.987 Well, I can click on this home button over here, 0:02:45.987,0:02:48.954 and that will take us up to the inner solar system, 0:02:48.954,0:02:51.081 and now we're looking at the rest of the solar system. 0:02:51.081,0:02:53.624 You can see, there's Saturn, there's Jupiter, 0:02:53.624,0:02:56.740 and while we're here, I want to point out something. 0:02:56.740,0:02:59.297 It's actually pretty busy. 0:02:59.297,0:03:01.386 Here we have the Mars Science Laboratory 0:03:01.386,0:03:03.929 on its way to Mars, just launched last weekend. 0:03:03.929,0:03:07.911 Here we have Juno on its cruise to Jupiter, there. 0:03:07.911,0:03:09.873 We have Dawn orbiting Vesta, 0:03:09.873,0:03:11.883 and we have over here New Horizons 0:03:11.883,0:03:14.341 on a straight shot to Pluto. 0:03:14.341,0:03:16.296 And I mention this because 0:03:16.296,0:03:19.101 there's this strange public perception that 0:03:19.101,0:03:21.894 NASA's dead, that the space shuttles stopped flying 0:03:21.894,0:03:24.478 and all of the sudden there's no more spacecraft out there. 0:03:24.478,0:03:29.057 Well, a lot of what NASA does is robotic exploration, 0:03:29.057,0:03:31.656 and we have a lot of spacecraft out there. 0:03:31.656,0:03:33.929 Granted, we're not sending humans up at the moment, 0:03:33.929,0:03:36.736 well at least with our own launch vehicles, 0:03:36.736,0:03:38.980 but NASA is far from dead, 0:03:38.980,0:03:42.310 and one of the reasons why we write a program like this 0:03:42.310,0:03:44.797 is so that people realize that there's so many other things 0:03:44.797,0:03:46.488 that we're doing. 0:03:46.488,0:03:48.210 Anyway, while we're here, again, 0:03:48.210,0:03:50.140 if you want to visit anything, 0:03:50.140,0:03:52.057 all you need to do is double-click. 0:03:52.057,0:03:54.627 So I'm just going to double-click on Vesta, 0:03:54.627,0:03:58.721 and here we have Dawn orbiting Vesta, 0:03:58.721,0:04:00.911 and this is happening right now. 0:04:00.911,0:04:05.118 I'm going to double-click on Uranus, and we can see 0:04:05.118,0:04:08.426 Uranus rotating on its side along with its moons. 0:04:08.426,0:04:12.218 You can see how it's tilted at about 89 degrees. 0:04:12.218,0:04:16.178 And just being able to visit different places 0:04:16.178,0:04:17.464 and go through different times, 0:04:17.464,0:04:20.559 we have data from 1950 to 2050. 0:04:20.559,0:04:22.776 Granted, we don't have everything in between, 0:04:22.776,0:04:24.542 because some of the data is hard to get. 0:04:24.542,0:04:28.457 Just being able to visit places in different times, 0:04:28.457,0:04:32.125 you can explore this for hours, 0:04:32.125,0:04:34.081 literally hours on end, 0:04:34.081,0:04:36.959 but I want to show you one thing in particular, 0:04:36.959,0:04:39.344 so I'm going to open up the destination tab, 0:04:39.344,0:04:42.731 spacecraft outer planet missions, Voyager 1, 0:04:42.731,0:04:45.731 and I'm going to bring up the Titan flyby. 0:04:45.731,0:04:48.521 So now we've gone back in time. 0:04:48.521,0:04:51.458 We're now riding along with Voyager 1. 0:04:51.458,0:04:54.855 The date here is November 11, 1980. 0:04:54.855,0:04:57.184 Now, there's a funny thing going on here. 0:04:57.184,0:04:59.377 It doesn't look like anything's going on. 0:04:59.377,0:05:01.477 It looks like I've paused the program. 0:05:01.477,0:05:03.503 It's actually running at real rate right now, 0:05:03.503,0:05:05.503 one second per second, and in fact, 0:05:05.503,0:05:09.061 Voyager 1 here is flying by Titan at 0:05:09.061,0:05:13.171 I think it's 38,000 miles per hour. 0:05:13.171,0:05:15.874 It only looks like nothing's moving because, well, 0:05:15.874,0:05:18.680 Saturn here is 700,000 miles away, 0:05:18.680,0:05:21.522 and Titan here is 4,000 to 5,000 miles away. 0:05:21.522,0:05:25.607 It's just the vastness of space makes it look like nothing's happening. 0:05:25.607,0:05:27.485 But to make it more interesting, 0:05:27.485,0:05:30.331 I'm going to speed up time, and we can watch 0:05:30.331,0:05:32.986 as Voyager 1 flies by Titan, 0:05:32.986,0:05:35.201 which is a hazy moon of Saturn. 0:05:35.201,0:05:37.505 It actually has a very thick atmosphere. 0:05:37.505,0:05:40.766 And I'm going to recenter the camera on Saturn, here. 0:05:40.766,0:05:44.655 I'm going to pull out, and I want to show you 0:05:44.655,0:05:47.885 Voyager 1 as it flies by Saturn. 0:05:47.885,0:05:50.135 There's a point to be made here. 0:05:50.135,0:05:52.777 With a 3D visualization like this, 0:05:52.777,0:05:56.558 we can not only just say Voyager 1 flew by Saturn. 0:05:56.558,0:05:58.180 There's a whole story to tell here. 0:05:58.180,0:06:01.036 And even better, because it's an interactive application, 0:06:01.036,0:06:03.016 you can tell the story for yourself. 0:06:03.016,0:06:05.221 If you want to pause it, you can pause it. 0:06:05.221,0:06:06.708 If you want to keep going, if you want to change 0:06:06.708,0:06:09.032 the camera angle, you can do that, 0:06:09.032,0:06:11.555 and because of that, I can show you 0:06:11.555,0:06:14.376 that Voyager 1 doesn't just fly by Saturn. 0:06:14.376,0:06:18.355 It actually flies underneath Saturn. 0:06:18.355,0:06:21.725 Now, what happens is, as it flies underneath Saturn, 0:06:21.725,0:06:24.636 Saturn grabs it gravitationally and flings it up 0:06:24.636,0:06:26.926 and out of the solar system, 0:06:26.926,0:06:29.964 so if I just keep letting this go, 0:06:29.964,0:06:34.621 you can see Voyager 1 fly up like that. 0:06:34.621,0:06:36.753 And, in fact, I'm going to go back to the solar system. 0:06:36.753,0:06:39.661 I'm going to go back to today, now, 0:06:39.661,0:06:43.307 and I want to show you where Voyager 1 is. 0:06:43.307,0:06:47.910 Right there, above, way above the solar system, 0:06:47.910,0:06:50.450 way beyond our solar system. 0:06:50.450,0:06:53.037 And here's the thing. Now you know how it got there. 0:06:53.037,0:06:54.665 Now you know why, and to me, 0:06:54.665,0:06:56.453 that's the point of this program. 0:06:56.453,0:06:59.726 You can manipulate it yourself. 0:06:59.726,0:07:03.022 You can fly around yourself and you can learn for yourself. 0:07:03.022,0:07:06.513 You know, the theme today is "The World In Your Grasp." 0:07:06.513,0:07:07.935 Well, we're trying to give you 0:07:07.935,0:07:09.532 the solar system in your grasp — (Laughter) — 0:07:09.532,0:07:11.081 and we hope once it's there, 0:07:11.081,0:07:13.334 you'll be able to learn for yourself 0:07:13.334,0:07:15.528 what we've done out there, and what we're about to do. 0:07:15.528,0:07:19.027 And my personal dream is for kids to take this 0:07:19.027,0:07:21.712 and explore and see the wonders out there 0:07:21.712,0:07:24.721 and be inspired, as I was as a kid, 0:07:24.721,0:07:26.279 to pursue STEM education 0:07:26.279,0:07:29.029 and to pursue a dream in space exploration. 0:07:29.029,0:07:32.251 Thank you. (Applause)
