Doomsday Machine

Spies discover that the Red Chinese have built a "doomsday machine" capable of destroying the surface of the Earth, and that they plan to use it within a matter of days. Meanwhile, Project Astra, a manned U.S. space mission to Venus, is in its final hours before launch when it is taken over by the military and nearly half of its all-male crew is replaced by women.
