The true story of the Russian lunar robots, which remained secret for more than two decades, can finally be told! These robots traversed over 31 miles across the lunar surface between 1970 and 1973, yet almost nothing was publicly known about them. One of the greatest technological achievements for the Soviet Union from the Space Race era, yet it was overshadowed by the success of the American Apollo program. This documentary tells the tale of the team of scientists that developed this technology detailing their triumphs and challenges. Personal accounts from the team of developers that worked on the various aspects of the rover and archival footage of tests reveal the size of this monumental task.
