Document Summary
Early development during the late apollo program. In the u. s. nasa reports directly to the president (presidents have huge say in what happens) Wanted it to be cheaper and more available. Needed something just to get to orbit and back. Not reusable and very expensive to launch. Capsule of the saturn v is replaced by the orbiter". Originally there was some discussion around having a jet powered the gilder. For reusability and so that it has its own landing ability. Challenge: spacecraft has to withstand the extremely high heat of reentry. Solution: thermal tile (24,000 - 35,000 tiles) However, the tiles are only on the bottom of the spacecraft. Thus, it must enter at a specific angle during reentry. Also first time commands over the components are digital instead of analogue. To figure out if the craft is aerodynamic and if the pilots could fly and land safely. A mostly disposable launch system (solid rocket boosters)
