WEBVTT 00:00:49.780 --> 00:00:51.780 Enough. 00:00:51.780 --> 00:00:53.320 Walk with me. 00:00:55.359 --> 00:00:58.719 Perhaps we should find you something a little less challenging. 00:00:58.740 --> 00:01:02.020 I don't understand, I planned everything. 00:01:02.020 --> 00:01:04.019 Let me do it again. 00:01:14.780 --> 00:01:17.620 Once upon a time... Really? 00:01:17.799 --> 00:01:20.679 This is a good one, I promise. 00:01:22.739 --> 00:01:25.439 What is the key to life on Earth? 00:01:25.879 --> 00:01:27.079 Water. 00:01:27.920 --> 00:01:29.480 Water. 00:01:44.239 --> 00:01:52.159 For a long time the origins of water and indeed life on our home planet remained an absolute mystery. 00:01:52.239 --> 00:01:59.359 So we began searching for answers beyond Earth. "Where could all this water have come from?" 00:01:59.359 --> 00:02:02.420 In time we turned to comets, 00:02:02.420 --> 00:02:10.960 one trillion celestial balls of ice, dust, complex molecules, left over from the birth of our Solar System 00:02:10.960 --> 00:02:17.360 Once thought of as messengers of doom and destruction and yet so enchanting, if we were to catch one, 00:02:17.360 --> 00:02:22.260 A staggeringly ambitious plan. 00:02:22.259 --> 00:02:24.379 Are you talking about the Rosetta mission? 00:02:25.240 --> 00:02:27.280 Throw me the probe. 00:02:35.680 --> 00:02:40.360 We harnessed whole planets and their gravity to chase down a comet 00:02:46.139 --> 00:02:48.599 So many things could've gone wrong 00:02:48.840 --> 00:02:55.319 A failure at launch, an error in the calculations, collisions, so many unknowns. 00:02:56.159 --> 00:03:01.259 With the technology we had back then, we may as well have been shooting from a slingshot. 00:03:02.500 --> 00:03:05.400 and tell me, what was it all for? 00:03:07.900 --> 00:03:08.800 Knowledge. 00:03:09.719 --> 00:03:10.580 Yes, 00:03:11.180 --> 00:03:14.719 But we also wanted to show what was possible. 00:03:33.560 --> 00:03:37.740 I know all this from the archives. There were bigger missions after. 00:03:37.740 --> 00:03:40.360 Yes, it was the first one to catch a comet. 00:03:41.639 --> 00:03:42.519 Ambition. 00:03:43.500 --> 00:03:44.900 Stubbornness. 00:03:45.180 --> 00:03:46.860 Nothing has changed. 00:03:47.139 --> 00:03:48.479 We fall, 00:03:48.479 --> 00:03:50.479 we pick ourselves up again, 00:03:50.860 --> 00:03:52.520 and we adapt 00:03:52.939 --> 00:03:54.819 I was watching you earlier, 00:03:54.819 --> 00:03:56.819 you actually did everything right. 00:03:57.419 --> 00:03:59.299 I destroyed your rock. 00:04:01.000 --> 00:04:03.180 I needed to see how you would react. 00:04:03.659 --> 00:04:04.799 You're ready. 00:04:07.960 --> 00:04:09.020 Reset. 00:04:26.600 --> 00:04:27.900 Nicely done. 00:04:29.339 --> 00:04:30.679 Let's begin. 00:04:32.680 --> 00:04:33.800 *whispers* Water.
