The Soviet space program had experienced great success in its early years, but by the mid-1960s the pace of success had slowed. While the
Voskhod programme achieved the first multi-crewed spaceflight and first
extravehicular activity (EVA), problems encountered led to its termination after only two flights, allowing the
United States to surpass the Soviet achievements with the
Project Gemini. The
Soyuz programme was intended to rejuvenate the program by developing
space rendezvous and
docking capability, and practical extravehicular activity without tiring the cosmonaut, as had been demonstrated by the United States Gemini. These capabilities would be required for the Soviet manned Lunar landing program and the
Salyut programme (space station).
Soyuz 1 had been launched with the goal of docking with the crewed
Soyuz 2 craft, but even before the second craft was launched, problems with Soyuz 1 made it clear that Soyuz 2 had to be cancelled before the landing of Soyuz 1. This saved the lives of the three-man Soyuz 2 crew; Soyuz 1 ended with the death of cosmonaut
Vladimir Komarov on 23 April 1967, due to a faulty parachute system. Soyuz 2 would have flown with the same defective system as Soyuz 1. As a result, the Soyuz spacecraft was revised for Soyuz 2 and Soyuz 3 in 1968. == Spaceflight ==
