From 1KM1KT description:
Russia ushered in the space age on October 4, 1957 with the launch Sputnik. That original 58cm metal sphere would in turn lead to a race between the superpowers to put men on the moon. After America won, all references to the Soviet moon program were denied, until the glasnost period of the early 199s.
Sputnik Lost is a reconstruction of an attempt to put men on the moon, less than two weeks before the launch of Apollo 11.
