During the next two decades, more than 1,600 spacecraft of all varieties were launched, mostly into the earth's orbit In addition, twelve men walked on the moon and returned home. By the end of the 1980s, there were more than 300 operational spacecraft and thousands of orbiting objects, mostly the spent, upper stages of launch vehicles and inert spacecraft.
