In the early 1960s, the Soviet Union began its Vostok program with a series of unmanned test flights to investigate the possibilities and means for a crewed mission, before sending Yuri Gagarin into space. Korabl-Sputnik 1, known as "Sputnik 4" in the West, was the first test flight of the Vostok program. The 4.5-ton spacecraft carried a variety of scientific instruments, including a television camera and a self-contained biological cabin with a dummy astronaut. The purpose of the mission was to study the operation of life support systems and the stresses of flight.
Claire's tests came out fine. Thanks to those who emailed.
