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.
