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. We really had take a created approach to come up with the geometer that we needed. 50 00:04:43.240 --> 00:04:48.410 And try to meet all of our requirements for interfaces and scientific requirements. 51 00:04:48.430 --> 00:04:51.540 When they start working on it they machine it out of a solid block of titanium. 52 00:04:51.560 --> 00:04:56.730 And what they do is they use a milling machine and actually mill away 53 00:04:56.750 --> 00:04:59.730 slight layers until they get the basic shape. 54 00:04:59.750 --> 00:05:09.730 [ music ] 55 00:05:09.750 --> 00:05:19.910 [ music ] 56 00:05:19.930 --> 00:05:29.910 [ music ] 57 00:05:29.930 --> 00:05:43.070 [ music ] 58 00:05:43.090 --> 00:05:50.250 OSIRIS REx is the acronym for Origins Spectral Interpretation Resource Identification Security Regolith Explorer 59 00:05:50.270 --> 00:05:56.440 Scheduled for launch in 2016 the mission will collect the first sample from this special type of asteroid 60 00:05:56.460 --> 00:05:58.799 that holds clues to the origin of the solar system. 61 00:05:58.820 --> 00:06:03.870 And just possibly the kinds of organic molecules that may have planted the seeds of life on Earth. 62 00:06:03.890 --> 00:06:12.240 In 2023 the OSIRIS REx mission will return a sample to Earth where it will be studied by scientist for generations to come. 63 00:06:12.260 --> 00:06:16.330 MAVEN is the Mars Atmosphere and Volatile EvolutioN mission. 64 00:06:16.350 --> 00:06:19.530 We're trying to understand basically why the climate changed on Mars, 65 00:06:19.550 --> 00:06:24.610 why Mars appears to have gone from an environment that was habitalble, to microorganisms 66 00:06:24.630 --> 00:06:29.790 at least, to the one that is the cold, dry, unihabitable environment we see today. 67 00:06:29.810 --> 00:06:33.930 By looking at the nature of the upper atmosphere today 68 00:06:33.950 --> 00:06:39.099 and how gases can be lost out of the atmosphere to space today. 69 00:06:39.120 --> 00:06:44.170 We learn about the processes that control the atmosphere and we are going to have a good understand of 70 00:06:44.190 --> 00:06:47.170 what the history of the atmosphere has been. 71 00:06:47.190 --> 00:06:47.340 [ music ] 72 00:06:47.360 --> 00:06:57.480 [ music ] 73 00:06:57.500 --> 00:07:07.530 [ music ] 74 00:07:07.550 --> 00:07:10.670 [ music ] 75 00:07:10.690 --> 00:07:14.770 A next generation space telescope 76 00:07:14.790 --> 00:07:18.930 designed to cause yet another giant leap forward in our 77 00:07:18.950 --> 00:07:21.099 understanding of the cosmos. 78 00:07:21.120 --> 00:07:28.280 It will carry some of the most advanced technologies ever placed on an orbiting observatory. 79 00:07:28.300 --> 00:07:35.450 [ music ] 80 00:07:35.470 --> 00:07:37.600 18 articulating mirror segments 81 00:07:37.620 --> 00:07:41.740 2.75 times the diameter of Hubble's primary mirror. 82 00:07:41.760 --> 00:07:44.789 Microshuttles.
