Apollo 22

Apollo 22 was a lunar mission launched in July, 1976, around the same time as the Viking missions to Mars. 

The mission consisted of the command module Rigil Kentaurus and lunar excursion module Arcturus. It is not revealed to the general public that a Slaver stasis box was discovered, containing a flying belt. Years later, the secret of synthetically generated gravity was derived from this discovery.

Background
One of the astronauts of this mission was named Calavicci, after Dean Stockwell's character in the series Quantum Leap.
