Korabl-Sputnik 4 was launched at 06:29:00 UTC on 9 March 1961, atop a Vostok-K carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome.[1] It was successfully placed into low Earth orbit. The spacecraft was only intended to complete a single orbit, so it was deorbited shortly after launch, and reentered on its first pass over the Soviet Union. It landed at 08:09:54 UTC, and was successfully recovered. During the descent, the mannequin was ejected from the spacecraft in a test of its ejection seat, and descended separately under its own parachute.[4]
