Doomsday Machine, also known as Escape from Planet Earth (video title), is an American science fiction film filmed in 1967 but completed without the original cast or sets in 1972.
A spy (Essie Lin Chia (fr)) discovers that the Chinese government has created a doomsday device (the “key” to which, “only Chairman Mao has”) capable of destroying the Earth and it will be activated in 72 hours. Soon after, Astra – a two-year return mission to Venus by the United States Space Program – has its time of launch speeded up and half of the male flight crew are replaced by women shortly before take-off, including one Russian. Shortly before blastoff military alerts are put into effect.
