When Was the First Animal in Space?

SpaceHistory

Quick Answer

Fruit flies became the first animals in space on 20 February 1947, launched aboard a US V-2 rocket; the first mammal in orbit was Laika, a Soviet dog launched on Sputnik 2 on 3 November 1957.

The Full Story

The history of animals in space began with fruit flies in 1947, sent aloft in a captured German V-2 rocket to study the effects of cosmic radiation. They were recovered alive. In 1949, Albert II (a rhesus monkey) became the first primate in space aboard a V-2, reaching 134 km altitude, but died on impact when his parachute failed. The most famous animal astronaut was Laika, a stray dog from Moscow launched aboard Sputnik 2 on 3 November 1957 — the first animal to orbit Earth. Soviet officials initially claimed she survived for a week, but it was revealed in 2002 that she died from overheating and stress within 5-7 hours. Her mission had no re-entry plan; the spacecraft was not designed to return. Ham the chimpanzee (1961) and Enos the chimp (1961) successfully orbited and returned for NASA. These animal missions provided crucial data on the physiological effects of microgravity and radiation before human spaceflight.

Key Facts

1.Fruit flies launched on a V-2 rocket on 20 February 1947 were the first animals to reach space (past the 100 km Karman line) and were recovered alive.
2.Laika the dog orbited Earth in Sputnik 2 on 3 November 1957 but died within hours from overheating — her spacecraft had no re-entry capability.
3.Ham the chimpanzee successfully performed tasks during his suborbital spaceflight on 31 January 1961, proving that living beings could function in microgravity — he lived until 1983.
