WEBVTT FILE 1 00:00:00.000 --> 00:00:08.640 [ MUSIC ] 2 00:00:08.640 --> 00:00:12.480 My first mission to the Hubble space telescope was in 1999. 3 00:00:12.480 --> 00:00:15.759 I'd been training for years for that mission but 4 00:00:15.759 --> 00:00:21.039 more personally i felt like I'd been training for that mission from birth. 5 00:00:21.039 --> 00:00:25.279 Because I loved taking things apart putting them back together as a kid, 6 00:00:25.279 --> 00:00:30.400 I liked to work on cars, and then fell in love with science. 7 00:00:30.400 --> 00:00:34.399 Studied to be an astronomer and astrophysicist and my job 8 00:00:34.399 --> 00:00:39.120 in training to be an astronomer was to build new scientific instruments 9 00:00:39.120 --> 00:00:42.879 to explore the universe. 10 00:00:42.879 --> 00:00:46.239 "Veteran spacewalker John Grunsfeld out of the 11 00:00:46.239 --> 00:00:50.480 airlock recognizable by the red stripes around his pant legs and up on the 12 00:00:50.480 --> 00:00:55.280 backpack of his suit the backpack housing all of his life support..." 13 00:00:55.280 --> 00:00:59.039 It was an amazing time growing up on the south side of Chicago 14 00:00:59.040 --> 00:01:02.879 and there was kind of a serendipity that I think set me on the path 15 00:01:02.880 --> 00:01:06.880 that I eventually followed which is I remember seeing the Gemini 16 00:01:06.880 --> 00:01:11.119 astronauts, I remember seeing the Apollo astronauts and Neil Armstrong and Buzz 17 00:01:11.119 --> 00:01:16.159 Aldrin landing on the moon. my ability to experience that 18 00:01:16.160 --> 00:01:20.360 space race going on and our success on the moon 19 00:01:20.360 --> 00:01:24.920 inspired me to tell my mom I want to be an astronaut. 20 00:01:24.920 --> 00:01:29.600 "Enhance the vision of Hubble into the deepest grandeur of our universe..." 21 00:01:29.600 --> 00:01:33.280 I was also very interested in science though and it was the science that 22 00:01:33.280 --> 00:01:37.360 propelled me through my young career going to high school getting involved 23 00:01:37.360 --> 00:01:40.479 with the science teachers and math teachers and then going on to college 24 00:01:40.480 --> 00:01:44.560 to study physics. And as a college student 25 00:01:44.560 --> 00:01:48.480 I approached a group that was doing research in astrophysics and said hey 26 00:01:48.480 --> 00:01:52.000 I'd like to work in astrophysics and so I started working with NASA 27 00:01:52.000 --> 00:01:56.479 missions, Small Astronomy Satellite 3 and then building instruments that went 28 00:01:56.480 --> 00:02:01.439 on high altitude balloons to look at neutron stars and black holes 29 00:02:01.440 --> 00:02:05.680 and so I was absolutely driven by learning about the universe. 30 00:02:05.680 --> 00:02:10.000 When I got my doctorate in physics at the university of Chicago 31 00:02:10.000 --> 00:02:14.560 I thought you know maybe having a doctorate in physics doing astronomy 32 00:02:14.560 --> 00:02:18.319 building instruments for astrophysics would be the kind of thing 33 00:02:18.319 --> 00:02:23.920 that might interest NASA in me as a potential astronaut. I filled 34 00:02:23.920 --> 00:02:26.879 out an application and sent it in to Houston 35 00:02:26.879 --> 00:02:31.519 and about six months later I got a call from Houston saying... 36 00:02:31.519 --> 00:02:35.760 "Would you be interested in an astronaut interview?" and I said "Of course!" 37 00:02:35.760 --> 00:02:41.599 That was 1989, I was not selected in that application process but I kept doing 38 00:02:41.600 --> 00:02:45.920 science, I worked with the Compton Gamma Ray Observatory looking at 39 00:02:45.920 --> 00:02:52.160 neutron stars and applied again and in 1992 was selected as an astronaut 40 00:02:52.160 --> 00:02:58.660 in the 14th group of astronauts. 41 00:02:58.660 --> 00:03:02.720 I got assigned to the Hubble mission, got to orbit 42 00:03:02.720 --> 00:03:06.240 in my space suit with Steve Smith, my space walking partner, 43 00:03:06.240 --> 00:03:09.600 and we went out of the hatch into a vacuum and I looked up and there was 44 00:03:09.600 --> 00:03:14.159 Hubble for real! I was on the robotic arm on the space 45 00:03:14.159 --> 00:03:18.000 shuttle and moving back towards the Hubble I got 46 00:03:18.000 --> 00:03:21.760 about three feet away from the Hubble and just had one of these surreal 47 00:03:21.760 --> 00:03:24.879 moments where I thought I just can't believe 48 00:03:24.879 --> 00:03:29.599 this is happening this is too cool! And I reached out with a finger and 49 00:03:29.599 --> 00:03:33.120 touched the Hubble just to prove you know that it was all real now of 50 00:03:33.120 --> 00:03:36.000 course I believed it was real but it was one of those moments where I felt 51 00:03:36.000 --> 00:03:39.760 like I had to go you know knock knock knock and say yeah 52 00:03:39.760 --> 00:03:44.400 yep we're really here and then went went off to work 53 00:03:44.400 --> 00:03:48.960 the space walk and we upgraded the Hubble. 54 00:03:48.960 --> 00:03:54.239 "This is a really tremendous adventure that we've been on a very challenging 55 00:03:54.239 --> 00:03:59.519 mission. Hubble isn't just a satellite it's about humanity's quest for 56 00:03:59.519 --> 00:04:03.040 knowledge. As Arthur C Clark says... "The only way of 57 00:04:03.040 --> 00:04:07.599 finding the limits of the possible is by going beyond them into the 58 00:04:07.599 --> 00:04:11.200 impossible." And on this mission we tried some things 59 00:04:11.200 --> 00:04:14.799 that many people said was impossible: Fixing STIS, 60 00:04:14.799 --> 00:04:20.959 repairing ACS, achieving all the content that we have in this mission but we've 61 00:04:20.959 --> 00:04:24.560 achieved that."
