Salyut 1, the first space station ever, was launched by the Soviet Union April 19, 1971. After Apollo 11 landed on the moon in July 1969, the Soviets shifted the emphasis of their space program to orbiting stations, with a possible moon landing later in the 1970s.
They began construction of Salyut 1 in early 1970 and planned to launch on April 12 to
coincide with Yuri Gagarin’s history flight on Vostok 1 technical problems postponed the launch until April 19.
The first crew to arrive was aboard Soyuz 10, launched April 22 with Vladimir Shatalov, Aleksei
Yeliseyev and Nikolai Rikavishnikov.
They managed to ‘soft-dock’ with Salyut
1 but hard-docking had to be aborted due to technical malfunctions. However, after undocking, toxic fumes began
to fill the capsule during re-entry and Rukavishnikov lost consciousness, but
all crew members were recovered successfully.
The second crew, Georgy Dobrovolsky, Vladislav Volkov and
Viktor Patsayev, launched in Soyuz 11
June 6, 1971 and docked with Salyut 1
and transferred to the space station.
They were able to carry out some of their tasks but after 23 days, their
mission was cut short due to problems aboard the station. They transferred back to Soyuz 11 and re-entered Earth’s atmosphere. A pressure relief valve malfunctioned during
the descent, depressurizing the capsule, suffocating the crew.
The Soviets then moved Salyut
1 to a higher orbit to be sure it would not be destroyed too early through
orbital decay. While this maneuver was
being fulfilled, the Soviets worked on an effort to redesign the capsules so
pressure suits could be worn during launch, docking, re-entry, etc.
Their efforts took too much time and in September, Salyut 1 was running low on attitude
control gas. On October 11, 1971, the
Soviets fired the main engines for a deorbit maneuver and the space station
burned up over the Pacific Ocean.
