Mouse into Space

Mouse into Space is a 1962 Tom and Jerry cartoon made in 1961 and directed by Gene Deitch and produced by William L. Snyder. It is the fifth of the thirteen cartoons made in Prague, Czechoslovakia (now known as Prague, Czech Republic).

Summary
Jerry, tired of Tom's repeated attempts to kill him, leaves the house to join a space program. Tom tries to convince Jerry to stay, but to no avail.

While Jerry is tested for the space program, Tom becomes so distraught that he becomes an alcoholic. However, he falls asleep in a large hose that then gets used to fill a rocket Jerry is in with rocket fuel. Miraculously, he survives, and climbs the outside of the rocket to find Jerry in the nose capsule. He proceeds to torment Jerry by spinning him in his sphere-shaped cockpit, but his success is short-lived when he accidentally steps on a button that ejects him into outer space. After brief encounters with a Soviet rocket with a bulldog and an asteroid field, Tom returns to Earth (not shown in space), soon followed by Jerry. The two then return to the house where the cartoon began, with Jerry now wearing a rocket-shaped badge. Tom places a lighter to the rocket, and it takes flight. Jerry then uses the rocket-shaped badge as a jet pack to chase after Tom. Tom packs his things and leaves while Jerry waves goodbye to him.
