1 00:00:12,259 --> 00:00:17,940 This mission is going to kick off a breathtakingly ambitious campaign to 2 00:00:17,940 --> 00:00:24,119 return samples from Mars to earth and as an astrobiologist who spends my life 3 00:00:24,119 --> 00:00:29,640 working on biosignatures, there could be nothing better. So, just to understand, 4 00:00:29,640 --> 00:00:33,840 you know, most of what we do now is we try to work with data that's coming back from 5 00:00:33,840 --> 00:00:39,450 orbiters, coming back from rovers, and the idea of having actual samples from Mars 6 00:00:39,450 --> 00:00:43,140 that have been carefully selected and returned to our planet in our 7 00:00:43,140 --> 00:00:46,950 laboratories where we can scour them and hit them with everything we've got 8 00:00:46,950 --> 00:00:51,560 I mean, it's just gonna be a huge paradigm shift for the kind of work we do. 9 00:00:54,660 --> 00:00:58,500 Well, there's plenty of amazing things that this mission could discover but 10 00:00:58,500 --> 00:01:03,539 like every astrobiologist you ask I'm going to say, of course, evidence for life 11 00:01:03,539 --> 00:01:08,790 and I guess I should qualify that like there are different types of life we 12 00:01:08,790 --> 00:01:13,380 could find evidence for ancestrally related life the the same kind of life 13 00:01:13,380 --> 00:01:17,189 we have here on earth that perhaps are just caught from the next planet over 14 00:01:17,189 --> 00:01:21,810 and of course that would be tremendously exciting in its own right it would give 15 00:01:21,810 --> 00:01:25,259 us a chance to replay the tape of evolution on another planet and 16 00:01:25,259 --> 00:01:31,110 rerun that experiment and see what turns out but what gets me most excited is 17 00:01:31,110 --> 00:01:35,850 this idea of an independent Genesis; a kind of life that's unlike any life 18 00:01:35,850 --> 00:01:39,900 that we've ever seen before and specifically when I think about the 19 00:01:39,900 --> 00:01:45,840 work that my group does we're really interested in this idea of agnostic biosignatures 20 00:01:46,020 --> 00:01:50,780 or a type of like evidence for life that doesn't presuppose the 21 00:01:50,790 --> 00:01:54,770 same molecular framework as life here on earth or the same underlying 22 00:01:54,770 --> 00:02:00,050 biochemistry and sometimes it feels like trying to imagine a color that 23 00:02:00,050 --> 00:02:04,130 you've never seen before. You know, figuring out ways that we could look for 24 00:02:04,130 --> 00:02:08,930 chemical complexity or unexpected accumulations or elements or isotopes 25 00:02:08,930 --> 00:02:14,600 that would be suggestive of life that could be just completely different 26 00:02:14,600 --> 00:02:18,820 from anything we'd seen before and I just think that would be better than
