The Space Shuttle’s ambitious schedule

Space ShuttleNASA prepares a preliminary schedule of Space Shuttle launches, covering the years 1979-1982 (and assuming the shuttle will be ready to launch in 1979). The ambitious schedule (which also assumes, in line with current planning, that the test orbiter Enterprise will be upgraded to spaceworthiness) includes almost-monthly flights from 1979 onward to deploy communications and weather satellites already on the drawing board, as well as frequent science missions with the cargo-bay-mounted Spacelab. On only the second test flight, the schedule has OV-102 (yet to be named Columbia) slated for a mission to the abandoned early 1970s space station Skylab, using a teleoperator retrieval system which also exists only on paper. While many of the schedule’s goals will be met, the delay in the shuttle program will be longer than NASA anticipates at this time.
