Some are as big as 3 00:00:18.390 --> 00:00:22.020 a bus with giant solar panels and bristling with cameras and detectors. 4 00:00:22.020 --> 00:00:26.160 Others are as small as a football with a single instrument. Well satellites have 5 00:00:26.160 --> 00:00:30.500 to be designed for a purpose. It's all about the how. It's all about the why. 6 00:00:30.500 --> 00:00:34.440 Scientists and engineers get together to design satellites for the purpose of 7 00:00:34.440 --> 00:00:39.480 exploring space. It's kind of like building a science laboratory without 8 00:00:39.480 --> 00:00:44.550 people. How exactly do we build the right spacecraft to capture the observations 9 00:00:44.550 --> 00:00:48.749 we need? How can we make sure the satellite will work without breaking or 10 00:00:48.749 --> 00:00:53.309 falling apart? That's the job of the scientists and engineers who work in the 11 00:00:53.309 --> 00:00:58.900 Mission Design Lab: to design for that purpose so they'll work in space. 12 00:00:58.900 --> 00:01:01.660 (music)
