1 00:00:00,033 --> 00:00:03,336 Although the moon is a relatively primitive body geologically, 2 00:00:03,336 --> 00:00:07,307 its arrested development provides insights into the early evolution 3 00:00:07,307 --> 00:00:10,310 of other rocky bodies like Venus, Earth, and Mars 4 00:00:17,851 --> 00:00:19,052 The Lunar Magnetotelluric 5 00:00:19,052 --> 00:00:23,523 Sounder is a geophysical instrument designed to probe the moon's deep interior 6 00:00:23,523 --> 00:00:24,791 and provide new information 7 00:00:24,791 --> 00:00:28,561 on the structure and geological evolution of our companion world. 8 00:00:28,695 --> 00:00:31,564 signals that we're looking at from the solar wind 9 00:00:31,564 --> 00:00:35,135 and the Earth's magnetosphere have frequencies that are way below 10 00:00:35,135 --> 00:00:37,270 what you might be familiar with as radio waves. 11 00:00:37,270 --> 00:00:40,874 These signals take minutes or even hours to complete a single cycle. 12 00:00:40,874 --> 00:00:41,875 The benefit of these 13 00:00:41,875 --> 00:00:45,612 very low frequency signals is that they penetrate deeply into the moon, 14 00:00:45,712 --> 00:00:47,380 This allows us to determine 15 00:00:47,380 --> 00:00:50,517 the temperature and composition of the interior of the moon. 16 00:00:50,617 --> 00:00:53,553 The magnetic fields are measured by a magnetometer 17 00:00:53,553 --> 00:00:56,556 The electric fields are measured between four probes 18 00:00:56,556 --> 00:00:59,893 that are deployed at 90 degree angles around the lander. 19 00:01:00,060 --> 00:01:02,028 LMS will be among the first 20 00:01:02,028 --> 00:01:05,465 geophysical measurements to assess interior properties of the moon 21 00:01:05,632 --> 00:01:08,701 Since Apollo. LMS is both simpler to operate 22 00:01:08,802 --> 00:01:13,139 and has better performance than these Apollo era experiments, Its demonstration 23 00:01:13,139 --> 00:01:16,843 paves the way for an even better version on a later CLPS mission, 24 00:01:17,143 --> 00:01:20,447 as well as opportunities for other worlds, including Mars. 25 00:01:20,547 --> 00:01:24,284 Our team at Southwest Research Institute, Heliospace Corporation, 26 00:01:24,284 --> 00:01:26,319 and NASA Goddard all contributed 27 00:01:26,319 --> 00:01:29,989 to this first extraterrestrial magneto measurement. 28 00:01:30,090 --> 00:01:34,594 Commercial Lunar Payload Services NASA and American companies working together.
