Gefangene des ewigen Kreises (1960)

The drama is set in a future where remote-controlled rockets orbit planets, and automated vehicles land on the moon, but humans haven’t ventured beyond. The Soviet Union announces a manned moon mission, prompting the US to rush its own mission to maintain its image. Three Americans are chosen for this dangerous task. The story suggests that international cooperation in space travel is essential and beneficial, but only possible if the Cold War ends.
