NASA complete the impact analysis for the delay Space Shuttle program. Columbia
(NASA Orbiter Vehicle Designation: OV-102) would be the first spaceworthy space shuttle in NASA's orbital fleet, and its first mission, STS-1, was reprogrammed for quarter two, 1981. Trouble was SkyLab had entered a dangerous orbit. If no further action was taken, SkyLab would re-enter the Earth's atmosphere sometime in 1979 and almost certainly break up on entry. The plan works and SkyLab is shifted into a higher orbit. But the 1982 mission from the Shuttle is a disaster and the Soviet Union has to rescue the American astronauts. Their success sets a precedent that was established with Apollo-Soyuz, and the the two nations merge their Space programs.
