Retro 51 - Apollo-Soyuz Project (Rollerball)

The Space Race, an era of fierce competition between American and Soviet space programs, was bookended by two events: the launch of Sputnik in 1957, and the Apollo-Soyuz Test Project in 1975. 

After almost 20 years of breakneck progress from both sides, which gave us the first man in space, the first spacewalk, the moon landings, and countless other achievements unimaginable a generation before, NASA and their Soviet counterpart the Soviet Academy of Sciences worked together on the Apollo-Soyuz Test Project to kick off a new age of international cooperation in space.
