WEBVTT FILE 1 00:00:00.000 --> 00:00:04.129 (music throughout) 2 00:00:04.166 --> 00:00:07.750 Nope, Lucy, still a little way to go before 3 00:00:07.750 --> 00:00:10.166 you get to your first Trojan asteroid. 4 00:00:10.583 --> 00:00:14.833 But it looks like you're coming up to the main belt asteroid, Donald Johanson. 5 00:00:16.000 --> 00:00:19.333 Right. This will give you a chance to check in on your instrumentation 6 00:00:19.583 --> 00:00:21.666 before you get out to the Trojans. 7 00:00:21.666 --> 00:00:23.750 This first instrument is called L'Ralph. 8 00:00:24.083 --> 00:00:26.666 It will take color images of the Trojan asteroids 9 00:00:26.833 --> 00:00:30.083 using visible and infrared light, helping scientists 10 00:00:30.083 --> 00:00:34.333 map craters and mountains and figure out what the asteroids are made out of. 11 00:00:34.750 --> 00:00:36.750 Next, this is L'LORRI. 12 00:00:36.750 --> 00:00:38.916 The long range reconnaissance imager. 13 00:00:39.500 --> 00:00:40.833 This camera will provide 14 00:00:40.833 --> 00:00:44.833 the most detailed images of the surfaces of the Trojan asteroids. 15 00:00:44.833 --> 00:00:49.250 To help scientists figure out what's been happening since our Solar System formed. 16 00:00:49.416 --> 00:00:52.750 This is L'TES, the thermal emission spectrometer, 17 00:00:53.166 --> 00:00:55.166 basically a touchless thermometer. 18 00:00:55.166 --> 00:00:58.500 It will measure the temperatures on the Trojan asteroids' surfaces 19 00:00:58.500 --> 00:01:01.916 to tell scientists whether the surfaces are rocky or dusty. 20 00:01:02.500 --> 00:01:05.916 Lastly, you couldn't get the job done without your tracking cameras 21 00:01:05.916 --> 00:01:10.333 or the T2CAMS to make sure the asteroids are always in view 22 00:01:10.916 --> 00:01:14.083 and the high gain antenna that lets you communicate with Earth. 23 00:01:14.250 --> 00:01:17.416 The scientists back at home will use your radio signals 24 00:01:17.583 --> 00:01:20.750 to measure the mass of each asteroid as you fly past it. 25 00:01:22.083 --> 00:01:24.416 That's right, Lucy. 26 00:01:24.500 --> 00:01:25.666 How could I forget? 27 00:01:25.666 --> 00:01:28.416 You also have two huge solar panels 28 00:01:28.666 --> 00:01:32.250 to give you electrical power as you fly out to the Trojan asteroids. 29 00:01:32.750 --> 00:01:36.166 Farther from the Sun than any previous solar powered mission. 30 00:01:36.750 --> 00:01:39.916 Just a bit longer now before you get to your first target. 31 00:01:40.666 --> 00:01:44.333 Rest up and get ready to put all of those instruments to good use. 32 00:01:45.083 --> 00:01:48.750 I'll check back in with you once you make it out to your first Trojan asteroid.
