1 00:00:04,789 --> 00:00:03,030 winds on mars can both help and hurt 2 00:00:06,789 --> 00:00:04,799 spacecraft so we're getting really 3 00:00:08,500 --> 00:00:06,799 creative in how to study winds on the 4 00:00:14,150 --> 00:00:08,510 surface of mars over a large region 5 00:00:15,829 --> 00:00:14,160 [Music] 6 00:00:18,070 --> 00:00:15,839 we're here at nasa's jet propulsion 7 00:00:20,710 --> 00:00:18,080 laboratory in the space flight 8 00:00:23,349 --> 00:00:20,720 operations facility also known as the 9 00:00:25,830 --> 00:00:23,359 dark room this is where engineers send 10 00:00:27,990 --> 00:00:25,840 commands and receive data from jpl 11 00:00:30,870 --> 00:00:28,000 missions including nasa's mars 12 00:00:32,790 --> 00:00:30,880 reconnaissance orbiter now detailed 13 00:00:34,709 --> 00:00:32,800 images from the orbiter are helping 14 00:00:35,910 --> 00:00:34,719 scientists better understand martian 15 00:00:38,869 --> 00:00:35,920 winds 16 00:00:40,869 --> 00:00:38,879 leslie tamperi is mro's deputy project 17 00:00:42,950 --> 00:00:40,879 scientist leslie what are we seeing in 18 00:00:44,790 --> 00:00:42,960 these images so what you can see here 19 00:00:46,630 --> 00:00:44,800 are dark patches on the surface of the 20 00:00:48,709 --> 00:00:46,640 ice near the south polar region and 21 00:00:50,950 --> 00:00:48,719 they're created by gas jets that come 22 00:00:53,830 --> 00:00:50,960 from under that ice up through cracks 23 00:00:56,069 --> 00:00:53,840 and deliver that dust out onto the ice 24 00:00:58,549 --> 00:00:56,079 and the wind will carry that dust and 25 00:00:59,990 --> 00:00:58,559 lay it on the surface forming these fans 26 00:01:01,670 --> 00:01:00,000 and what we can do with this information 27 00:01:02,630 --> 00:01:01,680 is we can look at the directions and the 28 00:01:04,070 --> 00:01:02,640 sizes 29 00:01:06,550 --> 00:01:04,080 and we can try to understand what the 30 00:01:08,870 --> 00:01:06,560 wind field is doing and i understand 31 00:01:11,990 --> 00:01:08,880 that volunteers played a large role in 32 00:01:15,030 --> 00:01:12,000 this research yes they did we have taken 33 00:01:18,070 --> 00:01:15,040 about 75 000 images over all of mars 34 00:01:21,749 --> 00:01:18,080 with our mro highrise camera we used 35 00:01:23,749 --> 00:01:21,759 citizen scientists 80 000 volunteers to 36 00:01:25,109 --> 00:01:23,759 map these fans and map their directions 37 00:01:27,190 --> 00:01:25,119 and sizes 38 00:01:29,670 --> 00:01:27,200 why is it important to study wind 39 00:01:31,590 --> 00:01:29,680 direction on mars some of our landers 40 00:01:33,510 --> 00:01:31,600 and rovers have had wind measurements 41 00:01:34,950 --> 00:01:33,520 but only in a few locations at a few 42 00:01:36,550 --> 00:01:34,960 different times but winds are very 43 00:01:38,950 --> 00:01:36,560 important for understanding today's 44 00:01:40,550 --> 00:01:38,960 climate on mars but also for trying to 45 00:01:43,190 --> 00:01:40,560 understand how the climate was different 46 00:01:44,870 --> 00:01:43,200 in the past we also have huge dust 47 00:01:47,190 --> 00:01:44,880 storms that occur on mars sometimes but 48 00:01:49,749 --> 00:01:47,200 we don't understand why some storms 49 00:01:51,510 --> 00:01:49,759 become global and some don't so we're 50 00:01:52,950 --> 00:01:51,520 trying to understand the wind field to 51 00:01:55,109 --> 00:01:52,960 try to put all these pieces together to 52 00:01:57,429 --> 00:01:55,119 understand mars better and how does that 53 00:01:59,910 --> 00:01:57,439 information help protect nasa's 54 00:02:01,670 --> 00:01:59,920 spacecraft right it's very important for 55 00:02:03,910 --> 00:02:01,680 not only spacecraft but probably future 56 00:02:06,230 --> 00:02:03,920 human exploration as well because dust 57 00:02:08,389 --> 00:02:06,240 it can be dangerous to hardware 58 00:02:10,070 --> 00:02:08,399 for example on the perseverance rover 59 00:02:12,710 --> 00:02:10,080 we're fortunate enough to have a wind 60 00:02:14,229 --> 00:02:12,720 sensor and we're measuring dust devils 61 00:02:16,070 --> 00:02:14,239 and a couple of these dust devils and 62 00:02:18,309 --> 00:02:16,080 wind events were so large they picked up 63 00:02:20,309 --> 00:02:18,319 not only dust but bigger particles sand 64 00:02:21,510 --> 00:02:20,319 sized particles and in fact some of the 65 00:02:24,229 --> 00:02:21,520 wind sensors were damaged on the 66 00:02:26,630 --> 00:02:24,239 perseverance rover in other locations we 67 00:02:29,110 --> 00:02:26,640 see hardly any dust devils for example 68 00:02:30,790 --> 00:02:29,120 the inside lander has solar panels the 69 00:02:33,589 --> 00:02:30,800 solar panels are completely covered with 70 00:02:34,869 --> 00:02:33,599 dust and so the power is waning and we'd 71 00:02:36,150 --> 00:02:34,879 really like to see some dust devils 72 00:02:37,910 --> 00:02:36,160 coming by so that they could clean off 73 00:02:39,430 --> 00:02:37,920 those solar panels and provide insight 74 00:02:41,110 --> 00:02:39,440 with some more power 75 00:02:42,470 --> 00:02:41,120 so learning about the winds and the 76 00:02:44,630 --> 00:02:42,480 different environments and how they 77 00:02:46,630 --> 00:02:44,640 change across mars will really help us 78 00:02:48,710 --> 00:02:46,640 plan not only for the conditions for 79 00:02:51,750 --> 00:02:48,720 today's spacecraft there but also plan 80 00:02:54,390 --> 00:02:51,760 better for the future thank you leslie 81 00:02:58,070 --> 00:02:54,400 to get the latest updates follow at nasa 82 00:02:59,750 --> 00:02:58,080 jpl and at nasa mars on social media or 83 00:03:03,400 --> 00:02:59,760 take a deeper dive on
