nov 3, 1957 - Sputnik 2

Description:

First dog in space died within hours. The dog Laika, the first living creature to orbit the Earth, did not live nearly as long as Soviet officials led the world to believe. The animal, launched on a one-way trip on board Sputnik 2 in November 1957, was said to have died painlessly in orbit about a week after blast-off.
