Mission highlights

With the Salyut 3 space station successfully launched on 24 June 1974, Soyuz 14 was sent into orbit nine days later, on 3 July 1974. The craft docked with the space station the next day, performing a manual approach for the last 100 metres. The crew tested the suitability of Salyut 3 as a crewed military reconnaissance platform. They also tested Almaz station systems, such as the solar arrays. Increased solar activity raised safety issues, but it was decided radiation levels were within safe limits, so the flight continued.

Experiments were described by the Soviets, but analysts presumed that much time was taken up with unreported military activities. Claims were made in the aerospace press that objects were laid out at the Baikonur Cosmodrome to photograph to test a high-resolution camera system on board. Some of the experiments the Soviets described included studies of the heart and circulatory systems in orbit, studies of intracranial pressure, monitoring of blood composition, measuring of lung capacity and inhalation/exhalation rates and the testing of a water purification system which condensed moisture from the station's atmosphere.

The cosmonauts exercised for two hours each day to counter the effects of weightlessness. Because of this, they were able to climb from their Soyuz descent module without assistance when their flight ended on 19 July 1974. The crew left enough supplies on Salyut 3 to last the next crew at least six months.
