First Men in The Moon (1964 Film) - Spacesuits Used

Spacesuits Used

Two types of spacesuits are featured. During the events of the story, which take place in the 1890s, standard diving dresses, each fitted with a 1960s-type aqualung cylinder-worn backpack instead of a NASA-type life support backpack, and no lifeline or airline from outside, are used as spacesuits. No provision is made to heat the suit, prevent suit ballooning in space vacuum, or to protect the hands from space vacuum. Volatile organics in the diving suit's gutta percha/rubber would boil away rapidly in a space vacuum.

Cavor and Bedford have no radio and must make their helmets touch each other to talk in the vacuum (although the filmmakers violate this rule several times). It is not clear whether the Selenites have radio. The history of radio was only just starting when the 1890s events were set. Wireless communication from Cavor in the Moon appears in H.G. Wells's novel.
