1 00:00:00,010 --> 00:00:04,010 >>INTERVIEWER: Last November, NASA launched a new mission to investigate the mystery of how 2 00:00:04,030 --> 00:00:08,040 it became the red planet, and how it may have looked in the past. Now that 3 00:00:08,060 --> 00:00:12,050 mission is about to arrive, and here joining us from NASA's Goddard Space Flight Center 4 00:00:12,070 --> 00:00:16,080 in Greenbelt, Maryland is MAVEN Deputy Program Scientist Dr. 5 00:00:16,100 --> 00:00:20,120 Kelly Fast. Thank you for joining us. >>KELLY: Thank you. >>INTERVIEWER: After nearly 6 00:00:20,140 --> 00:00:24,130 a year-long journey, MAVEN is finally arriving at Mars. Tell us about the 7 00:00:24,150 --> 00:00:28,160 MAVEN mission entering Mars' atmosphere. >>KELLY: Well we're really excited because 8 00:00:28,180 --> 00:00:32,250 coming up here on Sunday, after launching last November, 9 00:00:32,270 --> 00:00:36,260 and a 10-month journey to Mars, MAVEN will finally be arriving 10 00:00:36,280 --> 00:00:40,290 at Mars coming up here on Sunday. We've got a really critical operation 11 00:00:40,310 --> 00:00:44,330 for MAVEN will be orienting itself and firing its rockets so that it can be 12 00:00:44,350 --> 00:00:48,350 captured into orbit around Mars. And after that white-knuckle 13 00:00:48,370 --> 00:00:52,360 period of time, MAVEN will settle into science 14 00:00:52,380 --> 00:00:56,400 operations and it will start studying the upper atmosphere of Mars. 15 00:00:56,420 --> 00:01:00,410 >>INTERVIEWER: What will MAVEN do as it orbits Mars? 16 00:01:00,430 --> 00:01:04,410 >>KELLY: Well MAVEN is the first mission that is designed to study Mars' 17 00:01:04,430 --> 00:01:08,430 upper atmosphere. And so MAVEN will deploy its instruments, 18 00:01:08,450 --> 00:01:12,450 that are uniquely designed for this mission, and it will make measurements 19 00:01:12,470 --> 00:01:16,460 of processes taking place in the upper atmosphere and its interaction with the Sun, 20 00:01:16,480 --> 00:01:20,560 things that lead to escape of the atmosphere, to try 21 00:01:20,580 --> 00:01:24,570 to determine what happened to Mars over time. Mars once 22 00:01:24,590 --> 00:01:28,600 was, appeared to be a warmer and wetter place with a thicker atmosphere, 23 00:01:28,620 --> 00:01:32,640 and it's not the case now. So MAVEN is going to try to answer some of those questions. 24 00:01:32,660 --> 00:01:36,650 >>INTERVIEWER: What else is NASA doing to try to better understand Mars, and what are our plans for 25 00:01:36,670 --> 00:01:40,680 the future? >>KELLY: Well, NASA has a vibrant program. We have the 26 00:01:40,700 --> 00:01:44,750 2016 launch of the InSight mission, which will 27 00:01:44,770 --> 00:01:48,790 land on Mars to study the interior. We have the 2020 rover which will be 28 00:01:48,810 --> 00:01:52,860 launched and rove Mars and make further measurements. 29 00:01:52,880 --> 00:01:56,920 And, MAVEN is part of that whole program of current missions 30 00:01:56,940 --> 00:02:00,940 and future missions that will try to characterize Mars from 31 00:02:00,960 --> 00:02:04,960 the surface out to space as part of that Journey to Mars 32 00:02:04,980 --> 00:02:09,010 to one day send future missions and humans to Mars 33 00:02:09,030 --> 00:02:13,030 one day. >>INTERVIEWER: How does studying the red planet's evolution help us 34 00:02:13,050 --> 00:02:17,070 understand the formation of other planets, including Earth? >>KELLY: Well certainly 35 00:02:17,090 --> 00:02:21,120 we look at Mars, and from all the evidence from all the other missions 36 00:02:21,140 --> 00:02:25,140 that have gone to Mars, that all these signs that Mars was a warmer 37 00:02:25,160 --> 00:02:29,230 and wetter place with a thicker atmosphere, and so if you had a planet that 38 00:02:29,250 --> 00:02:33,240 once perhaps looked more Earth-like, you want to answer those 39 00:02:33,260 --> 00:02:37,260 questions about what did happen to the planet. And so MAVEN will be looking at 40 00:02:37,280 --> 00:02:41,300 those processes in the upper atmosphere that take place that lead to escape 41 00:02:41,320 --> 00:02:45,320 of the atmosphere, to try to track that back through time to figure happened to Mars. 42 00:02:45,340 --> 00:02:49,340 >>INTERVIEWER: Sounds good, where can we learn more? >>KELLY: Well you can 43 00:02:49,360 --> 00:02:53,390 go to NASA.gov/MAVEN and you can find out 44 00:02:53,410 --> 00:02:57,390 lots of information about the MAVEN mission, animations, and 45 00:02:57,410 --> 00:03:01,430 images and such, but also links to social media so that you can go 46 00:03:01,450 --> 00:03:05,470 into orbit at Mars with us and you can find out more about the mission 47 00:03:05,490 --> 00:03:09,470 as the mission takes place. So come join us. >>INTERVIEWER: Dr. Kelly 48 00:03:09,490 --> 00:03:13,510 Fast, thank you for joining us. >>KELLY: Thank you. 49 00:03:13,530 --> 00:03:17,540 [beep beep... beep beep... beep beep...] 50 00:03:17,560 --> 00:03:21,610 [beep beep... beep beep...] 51 00:03:21,630 --> 00:03:25,670 52 00:03:25,690 --> 00:03:26,386
