Dialogue: 0,0:00:00.61,0:00:05.05,Default,,0000,0000,0000,,As a kid, I was fascinated with all things air and space.
Dialogue: 0,0:00:05.05,0:00:07.59,Default,,0000,0000,0000,,I would watch Nova on PBS.
Dialogue: 0,0:00:07.59,0:00:10.54,Default,,0000,0000,0000,,Our school would show Bill Nye the Science Guy.
Dialogue: 0,0:00:10.54,0:00:14.67,Default,,0000,0000,0000,,When I was in elementary school, my next door neighbor,
Dialogue: 0,0:00:14.67,0:00:16.52,Default,,0000,0000,0000,,he gave me a book for my birthday.
Dialogue: 0,0:00:16.52,0:00:17.69,Default,,0000,0000,0000,,It was an astronomy book,
Dialogue: 0,0:00:17.69,0:00:20.64,Default,,0000,0000,0000,,and I poured over that thing for hours on end,
Dialogue: 0,0:00:20.64,0:00:23.24,Default,,0000,0000,0000,,and it was a combination of all these things
Dialogue: 0,0:00:23.24,0:00:26.91,Default,,0000,0000,0000,,that inspired me to pursue space exploration
Dialogue: 0,0:00:26.91,0:00:31.38,Default,,0000,0000,0000,,as my own personal dream, and part of that dream was,
Dialogue: 0,0:00:31.38,0:00:33.99,Default,,0000,0000,0000,,I always wanted to just fly around the solar system
Dialogue: 0,0:00:33.99,0:00:37.38,Default,,0000,0000,0000,,and visit different planets and visit moons and spacecraft.
Dialogue: 0,0:00:37.38,0:00:42.08,Default,,0000,0000,0000,,Well, a number of years later, I graduated from UCLA
Dialogue: 0,0:00:42.08,0:00:44.26,Default,,0000,0000,0000,,and I found myself at NASA,
Dialogue: 0,0:00:44.26,0:00:46.36,Default,,0000,0000,0000,,working for the jet propulsion laboratory,
Dialogue: 0,0:00:46.36,0:00:49.06,Default,,0000,0000,0000,,and there our team was challenged
Dialogue: 0,0:00:49.06,0:00:53.45,Default,,0000,0000,0000,,to create a 3D visualization of the solar system,
Dialogue: 0,0:00:53.45,0:00:57.32,Default,,0000,0000,0000,,and today I want to show you what we've done so far.
Dialogue: 0,0:00:57.32,0:01:00.71,Default,,0000,0000,0000,,Now, the kicker is, everything I'm about to do here
Dialogue: 0,0:01:00.71,0:01:04.51,Default,,0000,0000,0000,,you can do at home, because we built this
Dialogue: 0,0:01:04.51,0:01:07.32,Default,,0000,0000,0000,,for the public for you guys to use.
Dialogue: 0,0:01:07.32,0:01:09.24,Default,,0000,0000,0000,,So what you're looking at right now is the Earth.
Dialogue: 0,0:01:09.24,0:01:11.22,Default,,0000,0000,0000,,You can see the United States and California
Dialogue: 0,0:01:11.22,0:01:13.99,Default,,0000,0000,0000,,and San Diego, and you can use the mouse
Dialogue: 0,0:01:13.99,0:01:16.05,Default,,0000,0000,0000,,or the keyboard to spin things around.
Dialogue: 0,0:01:16.05,0:01:19.49,Default,,0000,0000,0000,,Now, this isn't new. Anyone who's used Google Earth
Dialogue: 0,0:01:19.49,0:01:22.50,Default,,0000,0000,0000,,has seen this before, but one thing we like to say
Dialogue: 0,0:01:22.50,0:01:26.31,Default,,0000,0000,0000,,in our group is, we do the opposite of Google Earth.
Dialogue: 0,0:01:26.31,0:01:30.36,Default,,0000,0000,0000,,Google Earth goes from this view down to your backyard.
Dialogue: 0,0:01:30.36,0:01:33.89,Default,,0000,0000,0000,,We go from this view out to the stars.
Dialogue: 0,0:01:33.89,0:01:36.82,Default,,0000,0000,0000,,So the Earth is cool, but what we really want to show
Dialogue: 0,0:01:36.82,0:01:38.69,Default,,0000,0000,0000,,are the spacecraft,
Dialogue: 0,0:01:38.69,0:01:41.43,Default,,0000,0000,0000,,so I'm going to bring the interface back up,
Dialogue: 0,0:01:41.43,0:01:44.15,Default,,0000,0000,0000,,and now you're looking at a number of satellites
Dialogue: 0,0:01:44.15,0:01:45.09,Default,,0000,0000,0000,,orbiting the Earth.
Dialogue: 0,0:01:45.09,0:01:48.37,Default,,0000,0000,0000,,These are a number of our science space Earth orbiters.
Dialogue: 0,0:01:48.37,0:01:50.69,Default,,0000,0000,0000,,We haven't included military satellites and weather satellites
Dialogue: 0,0:01:50.69,0:01:52.70,Default,,0000,0000,0000,,and communication satellites and reconnaissance satellites.
Dialogue: 0,0:01:52.70,0:01:55.20,Default,,0000,0000,0000,,If we did, it would be a complete mess,
Dialogue: 0,0:01:55.20,0:01:57.26,Default,,0000,0000,0000,,because there's a lot of stuff out there.
Dialogue: 0,0:01:57.26,0:02:01.06,Default,,0000,0000,0000,,And the cool thing is, we actually created 3D models
Dialogue: 0,0:02:01.06,0:02:04.33,Default,,0000,0000,0000,,for a number of these spacecraft, so if you want to visit
Dialogue: 0,0:02:04.33,0:02:07.36,Default,,0000,0000,0000,,any of these, all you need to do is double-click on them.
Dialogue: 0,0:02:07.36,0:02:10.59,Default,,0000,0000,0000,,So I'm going to find the International Space Station,
Dialogue: 0,0:02:10.59,0:02:15.60,Default,,0000,0000,0000,,double-click, and it will take us all the way down to the ISS.
Dialogue: 0,0:02:15.60,0:02:18.21,Default,,0000,0000,0000,,And now you're riding along with the ISS
Dialogue: 0,0:02:18.21,0:02:21.40,Default,,0000,0000,0000,,where it is right now.
Dialogue: 0,0:02:21.40,0:02:23.19,Default,,0000,0000,0000,,And the other cool thing is, not only can we
Dialogue: 0,0:02:23.19,0:02:26.47,Default,,0000,0000,0000,,move the camera around, we can also control time,
Dialogue: 0,0:02:26.47,0:02:28.58,Default,,0000,0000,0000,,so I can slide this jog dial here
Dialogue: 0,0:02:28.58,0:02:30.88,Default,,0000,0000,0000,,to shuttle time forward, and now
Dialogue: 0,0:02:30.88,0:02:35.31,Default,,0000,0000,0000,,we can see what a sunset on the ISS would look like,
Dialogue: 0,0:02:35.31,0:02:40.76,Default,,0000,0000,0000,,and they get one every 90 minutes. (Laughter)
Dialogue: 0,0:02:40.76,0:02:43.35,Default,,0000,0000,0000,,All right, so what about the rest of it?
Dialogue: 0,0:02:43.35,0:02:45.99,Default,,0000,0000,0000,,Well, I can click on this home button over here,
Dialogue: 0,0:02:45.99,0:02:48.95,Default,,0000,0000,0000,,and that will take us up to the inner solar system,
Dialogue: 0,0:02:48.95,0:02:51.08,Default,,0000,0000,0000,,and now we're looking at the rest of the solar system.
Dialogue: 0,0:02:51.08,0:02:53.62,Default,,0000,0000,0000,,You can see, there's Saturn, there's Jupiter,
Dialogue: 0,0:02:53.62,0:02:56.74,Default,,0000,0000,0000,,and while we're here, I want to point out something.
Dialogue: 0,0:02:56.74,0:02:59.30,Default,,0000,0000,0000,,It's actually pretty busy.
Dialogue: 0,0:02:59.30,0:03:01.39,Default,,0000,0000,0000,,Here we have the Mars Science Laboratory
Dialogue: 0,0:03:01.39,0:03:03.93,Default,,0000,0000,0000,,on its way to Mars, just launched last weekend.
Dialogue: 0,0:03:03.93,0:03:07.91,Default,,0000,0000,0000,,Here we have Juno on its cruise to Jupiter, there.
Dialogue: 0,0:03:07.91,0:03:09.87,Default,,0000,0000,0000,,We have Dawn orbiting Vesta,
Dialogue: 0,0:03:09.87,0:03:11.88,Default,,0000,0000,0000,,and we have over here New Horizons
Dialogue: 0,0:03:11.88,0:03:14.34,Default,,0000,0000,0000,,on a straight shot to Pluto.
Dialogue: 0,0:03:14.34,0:03:16.30,Default,,0000,0000,0000,,And I mention this because
Dialogue: 0,0:03:16.30,0:03:19.10,Default,,0000,0000,0000,,there's this strange public perception that
Dialogue: 0,0:03:19.10,0:03:21.89,Default,,0000,0000,0000,,NASA's dead, that the space shuttles stopped flying
Dialogue: 0,0:03:21.89,0:03:24.48,Default,,0000,0000,0000,,and all of the sudden there's no more spacecraft out there.
Dialogue: 0,0:03:24.48,0:03:29.06,Default,,0000,0000,0000,,Well, a lot of what NASA does is robotic exploration,
Dialogue: 0,0:03:29.06,0:03:31.66,Default,,0000,0000,0000,,and we have a lot of spacecraft out there.
Dialogue: 0,0:03:31.66,0:03:33.93,Default,,0000,0000,0000,,Granted, we're not sending humans up at the moment,
Dialogue: 0,0:03:33.93,0:03:36.74,Default,,0000,0000,0000,,well at least with our own launch vehicles,
Dialogue: 0,0:03:36.74,0:03:38.98,Default,,0000,0000,0000,,but NASA is far from dead,
Dialogue: 0,0:03:38.98,0:03:42.31,Default,,0000,0000,0000,,and one of the reasons why we write a program like this
Dialogue: 0,0:03:42.31,0:03:44.80,Default,,0000,0000,0000,,is so that people realize that there's so many other things
Dialogue: 0,0:03:44.80,0:03:46.49,Default,,0000,0000,0000,,that we're doing.
Dialogue: 0,0:03:46.49,0:03:48.21,Default,,0000,0000,0000,,Anyway, while we're here, again,
Dialogue: 0,0:03:48.21,0:03:50.14,Default,,0000,0000,0000,,if you want to visit anything,
Dialogue: 0,0:03:50.14,0:03:52.06,Default,,0000,0000,0000,,all you need to do is double-click.
Dialogue: 0,0:03:52.06,0:03:54.63,Default,,0000,0000,0000,,So I'm just going to double-click on Vesta,
Dialogue: 0,0:03:54.63,0:03:58.72,Default,,0000,0000,0000,,and here we have Dawn orbiting Vesta,
Dialogue: 0,0:03:58.72,0:04:00.91,Default,,0000,0000,0000,,and this is happening right now.
Dialogue: 0,0:04:00.91,0:04:05.12,Default,,0000,0000,0000,,I'm going to double-click on Uranus, and we can see
Dialogue: 0,0:04:05.12,0:04:08.43,Default,,0000,0000,0000,,Uranus rotating on its side along with its moons.
Dialogue: 0,0:04:08.43,0:04:12.22,Default,,0000,0000,0000,,You can see how it's tilted at about 89 degrees.
Dialogue: 0,0:04:12.22,0:04:16.18,Default,,0000,0000,0000,,And just being able to visit different places
Dialogue: 0,0:04:16.18,0:04:17.46,Default,,0000,0000,0000,,and go through different times,
Dialogue: 0,0:04:17.46,0:04:20.56,Default,,0000,0000,0000,,we have data from 1950 to 2050.
Dialogue: 0,0:04:20.56,0:04:22.78,Default,,0000,0000,0000,,Granted, we don't have everything in between,
Dialogue: 0,0:04:22.78,0:04:24.54,Default,,0000,0000,0000,,because some of the data is hard to get.
Dialogue: 0,0:04:24.54,0:04:28.46,Default,,0000,0000,0000,,Just being able to visit places in different times,
Dialogue: 0,0:04:28.46,0:04:32.12,Default,,0000,0000,0000,,you can explore this for hours,
Dialogue: 0,0:04:32.12,0:04:34.08,Default,,0000,0000,0000,,literally hours on end,
Dialogue: 0,0:04:34.08,0:04:36.96,Default,,0000,0000,0000,,but I want to show you one thing in particular,
Dialogue: 0,0:04:36.96,0:04:39.34,Default,,0000,0000,0000,,so I'm going to open up the destination tab,
Dialogue: 0,0:04:39.34,0:04:42.73,Default,,0000,0000,0000,,spacecraft outer planet missions, Voyager 1,
Dialogue: 0,0:04:42.73,0:04:45.73,Default,,0000,0000,0000,,and I'm going to bring up the Titan flyby.
Dialogue: 0,0:04:45.73,0:04:48.52,Default,,0000,0000,0000,,So now we've gone back in time.
Dialogue: 0,0:04:48.52,0:04:51.46,Default,,0000,0000,0000,,We're now riding along with Voyager 1.
Dialogue: 0,0:04:51.46,0:04:54.86,Default,,0000,0000,0000,,The date here is November 11, 1980.
Dialogue: 0,0:04:54.86,0:04:57.18,Default,,0000,0000,0000,,Now, there's a funny thing going on here.
Dialogue: 0,0:04:57.18,0:04:59.38,Default,,0000,0000,0000,,It doesn't look like anything's going on.
Dialogue: 0,0:04:59.38,0:05:01.48,Default,,0000,0000,0000,,It looks like I've paused the program.
Dialogue: 0,0:05:01.48,0:05:03.50,Default,,0000,0000,0000,,It's actually running at real rate right now,
Dialogue: 0,0:05:03.50,0:05:05.50,Default,,0000,0000,0000,,one second per second, and in fact,
Dialogue: 0,0:05:05.50,0:05:09.06,Default,,0000,0000,0000,,Voyager 1 here is flying by Titan at
Dialogue: 0,0:05:09.06,0:05:13.17,Default,,0000,0000,0000,,I think it's 38,000 miles per hour.
Dialogue: 0,0:05:13.17,0:05:15.87,Default,,0000,0000,0000,,It only looks like nothing's moving because, well,
Dialogue: 0,0:05:15.87,0:05:18.68,Default,,0000,0000,0000,,Saturn here is 700,000 miles away,
Dialogue: 0,0:05:18.68,0:05:21.52,Default,,0000,0000,0000,,and Titan here is 4,000 to 5,000 miles away.
Dialogue: 0,0:05:21.52,0:05:25.61,Default,,0000,0000,0000,,It's just the vastness of space makes it look like nothing's happening.
Dialogue: 0,0:05:25.61,0:05:27.48,Default,,0000,0000,0000,,But to make it more interesting,
Dialogue: 0,0:05:27.48,0:05:30.33,Default,,0000,0000,0000,,I'm going to speed up time, and we can watch
Dialogue: 0,0:05:30.33,0:05:32.99,Default,,0000,0000,0000,,as Voyager 1 flies by Titan,
Dialogue: 0,0:05:32.99,0:05:35.20,Default,,0000,0000,0000,,which is a hazy moon of Saturn.
Dialogue: 0,0:05:35.20,0:05:37.50,Default,,0000,0000,0000,,It actually has a very thick atmosphere.
Dialogue: 0,0:05:37.50,0:05:40.77,Default,,0000,0000,0000,,And I'm going to recenter the camera on Saturn, here.
Dialogue: 0,0:05:40.77,0:05:44.66,Default,,0000,0000,0000,,I'm going to pull out, and I want to show you
Dialogue: 0,0:05:44.66,0:05:47.88,Default,,0000,0000,0000,,Voyager 1 as it flies by Saturn.
Dialogue: 0,0:05:47.88,0:05:50.14,Default,,0000,0000,0000,,There's a point to be made here.
Dialogue: 0,0:05:50.14,0:05:52.78,Default,,0000,0000,0000,,With a 3D visualization like this,
Dialogue: 0,0:05:52.78,0:05:56.56,Default,,0000,0000,0000,,we can not only just say Voyager 1 flew by Saturn.
Dialogue: 0,0:05:56.56,0:05:58.18,Default,,0000,0000,0000,,There's a whole story to tell here.
Dialogue: 0,0:05:58.18,0:06:01.04,Default,,0000,0000,0000,,And even better, because it's an interactive application,
Dialogue: 0,0:06:01.04,0:06:03.02,Default,,0000,0000,0000,,you can tell the story for yourself.
Dialogue: 0,0:06:03.02,0:06:05.22,Default,,0000,0000,0000,,If you want to pause it, you can pause it.
Dialogue: 0,0:06:05.22,0:06:06.71,Default,,0000,0000,0000,,If you want to keep going, if you want to change
Dialogue: 0,0:06:06.71,0:06:09.03,Default,,0000,0000,0000,,the camera angle, you can do that,
Dialogue: 0,0:06:09.03,0:06:11.56,Default,,0000,0000,0000,,and because of that, I can show you
Dialogue: 0,0:06:11.56,0:06:14.38,Default,,0000,0000,0000,,that Voyager 1 doesn't just fly by Saturn.
Dialogue: 0,0:06:14.38,0:06:18.36,Default,,0000,0000,0000,,It actually flies underneath Saturn.
Dialogue: 0,0:06:18.36,0:06:21.72,Default,,0000,0000,0000,,Now, what happens is, as it flies underneath Saturn,
Dialogue: 0,0:06:21.72,0:06:24.64,Default,,0000,0000,0000,,Saturn grabs it gravitationally and flings it up
Dialogue: 0,0:06:24.64,0:06:26.93,Default,,0000,0000,0000,,and out of the solar system,
Dialogue: 0,0:06:26.93,0:06:29.96,Default,,0000,0000,0000,,so if I just keep letting this go,
Dialogue: 0,0:06:29.96,0:06:34.62,Default,,0000,0000,0000,,you can see Voyager 1 fly up like that.
Dialogue: 0,0:06:34.62,0:06:36.75,Default,,0000,0000,0000,,And, in fact, I'm going to go back to the solar system.
Dialogue: 0,0:06:36.75,0:06:39.66,Default,,0000,0000,0000,,I'm going to go back to today, now,
Dialogue: 0,0:06:39.66,0:06:43.31,Default,,0000,0000,0000,,and I want to show you where Voyager 1 is.
