S81-33179 (12 April 1981) --- Though their STS-1 task has been performed, the two solid rocket boosters (SRB) still glow following their jettisoning from the space shuttle Columbia on its way to many firsts. Among the history recorded by the spacecraft is the marking of a mission in a reusable spacecraft. STS-1 is NASA's first manned mission since the Apollo-Soyuz Test Project in 1975. Inside the cabin of the climbing spacecraft are astronauts John W. Young and Robert L. Crippen. Photo credit: NASA

S73-27666 (May-June 1973) --- A close-up view of the Soyuz spacecraft which was part of the Apollo-Soyuz Test Project exhibit at the 30th International Aeronautics and Space Exhibition held May 24 ? June 3, 1973 at the Le Bourget Airport in Paris, France. The ASTP exhibit was co-sponsored by the United States and the Union of Soviet Socialist Republics. An agreement between the U.S. and the USSR provides for the docking in Earth orbit of the Soyuz and Apollo in the summer of 1975. The Apollo spacecraft is out of view to the left. At the far left, a mock-up of a Docking Module connects the Apollo with the Soyuz. The spherical-shaped portion of the Soyuz is called the orbital section. The middle section with the lettering ?CCCP? (USSR) on it is called the cosmonauts? cabin. Two solar panels extend out from the machines and panel section.
