The Space Shuttle
NASA's next major project was the
space shuttle, which the agency promoted as a means of reliable and economical
access to space. As it developed the shuttle during the 1970s, NASA also pursued
the Apollo-Soyuz Test Project with the Soviets, Skylab, and a series of unmanned
exploratory missions, including the Viking probe of Mars. The shuttle began
flying in 1981. Although the shuttle proved not to be as efficient as NASA
promised, more than twenty flights had taken place by the end of 1985.
Space Shuttle Columbia, April
On 28 January 1986, tragedy struck. The shuttle Challenger exploded
seventy-three seconds after liftoff, killing all seven astronauts aboard. The
disaster stunned NASA and the nation. A presidential commission investigating
the accident sharply criticized NASA's management and safety procedures. After
revamping the program, shuttle flights resumed in 1988.
The Space Station
The 1990s saw NASA make significant improvements to the shuttle program,
pursue a variety of unmanned missions (including the impressive Hubble Space
Telescope), continue research in aeronautics and space science, and work on its
next major project, an orbiting space station. Hampered by budgetary restraints
and widespread criticisms of the initial station design, the project progressed
slowly. In the mid-1980s, NASA had announced that the station would be a
cooperative effort. Fifteen other nations-including Russia, America's former
rival in space-eventually joined with the United States to develop the
International Space Station (ISS). Russia's own space station, Mir, orbited the
Earth from 1986 to 2001.
In late 1998, the first of more than forty space flights needed to transport
and assemble the station in orbit took place. Plans originally called for
international crews of up to seven astronauts to stay on the station for three
to six months at a time. However, unexpectedly high development costs, plus
unexpectedly low financial contributions from Russia, forced NASA to scale back
the project to save money. The first crew to inhabit the station arrived in
November 2000. Assembly of the station was scheduled for completion around 2004.
