WEBVTT FILE 1 00:00:00.867 --> 00:00:03.703 As the Artemis missions journey to the Moon, 2 00:00:03.703 --> 00:00:05.605 finding and understanding water 3 00:00:05.605 --> 00:00:08.575 will be key to establishing a renewed presence there. 4 00:00:08.708 --> 00:00:10.410 Water is critical to life 5 00:00:10.410 --> 00:00:12.946 and can be broken into Hydrogen and Oxygen, 6 00:00:12.946 --> 00:00:15.448 which can serve as rocket fuel. 7 00:00:15.515 --> 00:00:17.117 The Lunar IceCube mission, 8 00:00:17.117 --> 00:00:18.885 led by Morehead State University, 9 00:00:18.918 --> 00:00:21.688 will carry a NASA instrument called BIRCHES 10 00:00:21.688 --> 00:00:24.657 to investigate water ice on the Moon. 11 00:00:24.657 --> 00:00:27.627 Lunar IceCube is a small satellite 12 00:00:27.627 --> 00:00:30.597 designed to provide observations at diverse lunar regions 13 00:00:30.597 --> 00:00:33.233 to better understand the Moon's water cycle. 14 00:00:33.633 --> 00:00:36.236 NASA scientists will use BIRCHES data 15 00:00:36.236 --> 00:00:38.038 to understand where water is, 16 00:00:38.038 --> 00:00:39.172 what its origins are, 17 00:00:39.205 --> 00:00:40.907 and how we can use it. 18 00:00:41.174 --> 00:00:44.010 BIRCHES will also help map water in the exosphere, 19 00:00:44.010 --> 00:00:46.479 an extremely thin volume of atmosphere 20 00:00:46.546 --> 00:00:48.181 surrounding the Moon. 21 00:00:48.181 --> 00:00:50.183 Scientists are interested in understanding 22 00:00:50.183 --> 00:00:53.153 the absorption and release of water in the Moon's regolith, 23 00:00:53.219 --> 00:00:55.555 dust and rocks on the lunar surface. 24 00:00:55.588 --> 00:00:57.857 This research will help scientists and engineers 25 00:00:57.857 --> 00:01:00.827 better understand changes to water on the Moon over time. 26 00:01:01.728 --> 00:01:03.863 BIRCHES uses a similar technology 27 00:01:03.863 --> 00:01:06.166 that flew on the OSIRIS-REx mission, 28 00:01:06.199 --> 00:01:08.301 which studied the asteroid Bennu. 29 00:01:08.334 --> 00:01:10.570 However, BIRCHES has been miniaturized 30 00:01:10.603 --> 00:01:13.573 to 1/6 the mass of the instrument on OSIRIS-REx 31 00:01:13.573 --> 00:01:16.543 and is roughly the size of an eight-inch tisssue box. 32 00:01:17.343 --> 00:01:20.013 The Lunar IceCube spacecraft and BIRCHES instrument 33 00:01:20.013 --> 00:01:21.748 will launch as a secondary payload 34 00:01:21.748 --> 00:01:23.416 on the Artemis I mission, 35 00:01:23.416 --> 00:01:26.586 helping pave the way for future crewed exploration missions 36 00:01:26.619 --> 00:01:28.721 to the lunar surface.
