Sputnik 2 [SEP] Introduction
Sputnik 2 (, , "Satellite 2"), or Prosteyshiy Sputnik 2 (PS-2, , "Simplest Satellite 2") was the second spacecraft launched into Earth orbit, on 3 November 1957, and the first to carry a living animal, a Soviet space dog named Laika. Laika died on the fourth orbit due to overheating caused by an air conditioning malfunction. Launched by the U.S.S.R., Sputnik 2 was a 4 meters (13 feet) high cone-shaped capsule with a base diameter of 2 meters (6.6 feet) that weighed around 500 kg, though it was not designed to separate from the rocket core that brought it to orbit, bringing the total mass in orbit to 7.79 tonnes.
