Sputnik 2 Carries Laika into Earth Orbit
Following the successful launch of Sputnik 1 in October 1957, Soviet leader Nikita Khrushchev sought another propaganda triumph to coincide with the 40th anniversary of the October Revolution. Engineers rapidly adapted the Sputnik design into a larger capsule capable of sustaining a living passenger. On November 3, 1957, the Soviet Union launched Sputnik 2 from the Baikonur Cosmodrome carrying Laika, a stray dog from Moscow streets. The 508-kilogram satellite entered orbit successfully, marking the first time a living creature orbited Earth. Telemetry confirmed Laika survived the launch stresses but died hours later from overheating caused by inadequate thermal control. The mission demonstrated that biological organisms could endure spaceflight conditions despite the tragic outcome for the animal.
