WEBVTT FILE 1 00:00:00.150 --> 00:00:04.280 My name is Tom Williams; I'm a systems engineer working on the TDRS program 2 00:00:04.280 --> 00:00:08.450 since 1975. I was working at Goddard here doing, 3 00:00:08.450 --> 00:00:12.610 ah, research in electric propulsion back in the, in the 4 00:00:12.610 --> 00:00:16.820 late 60s and in 1975 they called me, 5 00:00:16.820 --> 00:00:21.000 the TDRS project did ask if I would take on the engineering 6 00:00:21.000 --> 00:00:25.060 job as a propulsion engineer for that program that was just getting started. 7 00:00:25.060 --> 00:00:29.100 Well the launch of the first TDRS, We had an anomaly with the launch vehicle 8 00:00:29.100 --> 00:00:33.150 and normally they're supposed to drop us off and we immediately 9 00:00:33.150 --> 00:00:37.220 go into configuring the spacecraft and deploying all 10 00:00:37.220 --> 00:00:41.350 the appendages and instead we were spinning end over end at 30 11 00:00:41.350 --> 00:00:45.540 rpm and we weren't in the right orbit. So, what happened then we tried 12 00:00:45.540 --> 00:00:49.600 to figure out what we could do about it and eventually figured out a way we could 13 00:00:49.600 --> 00:00:53.680 actually get in the correct orbit with the small thrusters that we had 14 00:00:53.680 --> 00:00:57.820 on board. We did a burn every, every day and it took us 30 days and we eventually 15 00:00:57.820 --> 00:01:02.010 got there and that spacecraft lasted 27 years. I think the biggest thing 16 00:01:02.010 --> 00:01:06.190 about TDRS and I don't know why this is true and it's probably true to other programs too. 17 00:01:06.190 --> 00:01:10.370 But it really did turn into like a family. We had a lot of 18 00:01:10.370 --> 00:01:14.550 picnics for the families, parties. Our working relationship in those 19 00:01:14.550 --> 00:01:18.680 days you could argue face to face with people and then go have lunch. It was, 20 00:01:18.680 --> 00:01:22.830 I think kind of unique for a big program like that it was a very close 21 00:01:22.830 --> 00:01:25.030 relationship with all those employees. 22 00:01:25.030 --> 00:01:29.230 Beep, Beep, Beep.. 23 00:01:29.230 --> 00:01:30.400
