Space Rocket History #11 – Sputnik 2 – Laika: The Space Dog

Sputnik 2 was the second spacecraft launched into Earth orbit and was the first to launch a living creature. The satellite was a 4 meter high cone-shaped capsule with a base diameter of 2 meters. It contained several compartments for radio transmitters, a telemetry system, a programming unit, a regeneration and temperature control system for the cabin, and scientific instruments. A separate sealed cabin contained the first space passenger Laika, the space dog. Engineering and biological data were transmitted by the telemetry system to Earth for 15 minutes of each 103 minute orbit.  Two spectrophotometers were on board for measuring solar radiation and cosmic rays. A television camera was mounted in the passenger compartment to observe Laika.
