1 00:00:00,118 --> 00:00:03,737 Is there life on Mars? 2 00:00:04,270 --> 00:00:06,774 NASA. 3 00:00:06,774 --> 00:00:07,952 We Asked a NASA Scientist. 4 00:00:08,317 --> 00:00:11,344 So we've been looking for life on Mars for a long time. 5 00:00:11,644 --> 00:00:15,115 And while NASA hasn't found any evidence of life now, 6 00:00:15,248 --> 00:00:19,519 we found lots of evidence that Mars could have supported life in the past. 7 00:00:19,853 --> 00:00:22,322 There's lots of pieces of evidence that say there was once 8 00:00:22,322 --> 00:00:26,493 a huge ocean on Mars and an atmosphere that could have supported life. 9 00:00:26,893 --> 00:00:29,629 But there's still a lot of Mars left to explore. 10 00:00:29,829 --> 00:00:33,733 There are places that are potentially habitable, like the deep subsurface. 11 00:00:33,901 --> 00:00:38,371 There are places underground that could have fluids in them or organisms could live, 12 00:00:38,571 --> 00:00:42,308 and they'd be protected from the radiation that's so harmful on the surface. 13 00:00:42,642 --> 00:00:46,046 We're just now getting instruments onto the Martian surface 14 00:00:46,246 --> 00:00:49,482 that can help us understand these potentially habitable places 15 00:00:49,682 --> 00:00:53,653 and we can ask deeper questions about the potential for habitability 16 00:00:53,953 --> 00:00:55,588 in those rock cores. 17 00:00:55,588 --> 00:00:57,690 So is there life on Mars? 18 00:00:57,690 --> 00:01:01,828 Not that we've found yet, but there's still a lot of Mars left to explore.
