They figured that something would come up and we're going to have another shuttle and another shuttle. 8 00:00:42,390 --> 00:00:45,520 But I guess all good things have to end at one point. 9 00:00:45,540 --> 00:00:49,580 And lift-off of the Delta II with the NPP satellite. 10 00:00:49,600 --> 00:00:55,680 Blazing the way at new technology for climate research and weather forcasting. 11 00:00:55,700 --> 00:01:01,860 If you were to go looking for water on the moon, how would you find a good place to start digging? 12 00:01:01,880 --> 00:01:04,970 NASA's Lunar Reconnaissance Orbiter has a pretty unique answer. 13 00:01:04,989 --> 00:01:07,149 Count the neutrons coming from the moon. 14 00:01:07,170 --> 00:01:10,320 LRO's LEN instrument or Lunar Explorer Neutron Detector 15 00:01:10,340 --> 00:01:12,500 is specifically designed to do just this. 16 00:01:12,520 --> 00:01:15,619 But how does counting neutrons help you find water? 17 00:01:15,640 --> 00:01:19,670 The answer lies in hydrogen, the smallest atom, and how those neutrons interact with it. 18 00:01:19,690 --> 00:01:22,840 So where do those neutrons come from and what do they do? 19 00:01:22,860 --> 00:01:33,020 [ music ] 20 00:01:33,040 --> 00:01:43,110 [ music ] 21 00:01:43,130 --> 00:01:48,289 [ music ] 22 00:01:48,310 --> 00:01:53,340 [ music ] 23 00:01:53,360 --> 00:01:58,530 24 00:01:58,550 --> 00:02:03,880 Two weeks ago we had another mission over Pine Island glacier. 25 00:02:03,900 --> 00:02:10,070 When looking out of the window of the aircraft we noticed a farly large crack in the ice shelf. 26 00:02:10,090 --> 00:02:16,260 And I talked back to colleagues in the US that downloaded satellite images 27 00:02:16,280 --> 00:02:22,430 and they reported that this crack has formed sometime between end of September or early October. 28 00:02:22,450 --> 00:02:28,540 At the moment the crack is about 80 meters wide. If the crack continues to propagate 29 00:02:28,560 --> 00:02:34,680 It's about an iceberg that has area of about 800 square kilometer that will eventually break 30 00:02:34,700 --> 00:02:36,679 from the Pine Island glacier. 31 00:02:36,700 --> 00:02:46,760 [ music ] 32 00:02:46,780 --> 00:02:56,950 [ music ] 33 00:02:56,970 --> 00:03:07,120 [ music ] 34 00:03:07,140 --> 00:03:17,119 [ music ] 35 00:03:17,140 --> 00:03:21,290 [ music ] 36 00:03:21,310 --> 00:03:24,480 So this has implications for the origin of life on Earth. 37 00:03:24,500 --> 00:03:29,510 We know that meteorites contain amino acids which are the building blocks of proteins 38 00:03:29,530 --> 00:03:35,700 and now from our research nucleobases which are the building blocks of genetic material, 39 00:03:35,720 --> 00:03:38,880 like DNA and RNA, are also found in meteorites. 40 00:03:38,900 --> 00:03:42,990 So these things together could have seeded an early Earth with these really important 41 00:03:43,010 --> 00:03:47,109 molecules that could have built up to the larger molecules that you see today 42 00:03:47,130 --> 00:03:51,109 that are essential for biology. 43 00:03:51,130 --> 00:04:01,109 [ music ] 44 00:04:01,130 --> 00:04:11,290 [ music ] 45 00:04:11,310 --> 00:04:21,459 [ music ] 46 00:04:21,480 --> 00:04:31,830 [ music ] 47 00:04:31,850 --> 00:04:33,010 48 00:04:33,030 --> 00:04:38,080 When we started working on the part there was a lot that was aready in place before we begain actually conceptualizing 49 00:04:38,100 --> 00:04:43,220 what it would look like.
