TORTOISE
On September 15, 1968, the Soviet Union launched the spacecraft Zond 5 with a biological payload that includes two male turtles. On September 18, Zond 5 makes rounds around the moon and safely return to Earth on 21.
Turtles experienced a slight weight loss, but it was very much better than erupting in flames and burned to death at the launch. The mission of the Soviet Soyuz 20 (17 November 1975-16 February 1976) turtles kept in space for 90.5 days, a record for the longest duration for animals.
