Description


Salyut 6, launched on a Proton 8K82K rocket on 1977-09-29, marked the switch from engineering development stations to routine operations, and united the most effective elements from each of the previous stations. Her navigation system, made up of the Delta semi-automatic computer to depict the station's orbit and the Kaskad system to control its orientation, was based on that used on Salyut 4
Salyut 4
Salyut 4 was a Salyut space station launched on December 26, 1974 into an orbit with an apogee of 355 km, a perigee of 343 km and an orbital inclination of 51.6 degrees. It was essentially a copy of the DOS 3, and unlike its ill-fated sibling it was a complete success...

 together producing a peak of 4 kilowatts of power over 51 metres². The station's thermal regulation systems, which made use of a sophisticated arrangement of insulation and radiators, was also derived from that used on Salyut 4. In addition, Salyut 6 made use of environmental systems first used on Salyut 3

, and controlled her orientation using gyrodenes first tested on that station.

The most important feature on Salyut 6, however, was the addition of a second docking port on the aft end of the station, which allowed two spacecraft to be docked at once. This, in turn, allowed resident crews to receive shorter, 'visiting' expeditions whilst they remained on board, and for crew handovers to take place. Such handovers, with one expedition vacating the station only after the next had arrived, permitted the long sought-after aim of continuous occupation to move a step closer.

. These freighters, which brought supplies and extra equipment to keep the station replenished, helped ensure that the crew were always able to carry out useful scientific work aboard the station. In all, twelve Progress flights delivered over 20 tonnes of equipment, supplies and fuel.

, drawn from a common set of pressurised tanks, allowing the refuelling capabilities of the visiting Progress tankers to be exploited to the maximum effect. The entire engine and fuel storage assembly was contained within an unpressurised bay at the rear of the station, which was the same diameter as the main pressurised compartment. However, the replacement of the Soyuz

s, Salyut 6 was equipped with an inward-opening EVA hatch for on the side of the forward transfer compartment, which could be used as an airlock in a similar way to the system used on Salyut 4. This compartment contained two new semi-rigid spacesuits which allowed much greater flexibility than earlier suits, and could be donned within five minutes in case of an emergency. Finally, the station offered considerable improvements in living conditions over previous outposts, with machinery being soundproofed, the crews being provided with designated 'cots' for sleeping and the equipping of the station with a shower and extensive gymnasium.

Instruments


The primary instrument carried aboard the station was the BST-1M multispectral telescope, which could carry out astronomical observations in the infrared, ultraviolet and submillimetre spectra using a 1.5 metre-diameter mirror which was operated in cryogenic conditions at around −269 °C
Celsius

. The telescope could be operated only when Salyut 6 was on the night side of the Earth, and had its cover closed for the rest of the time.

The second major instrument was the MKF-6M multispectral camera, which carried out Earth-resources observations. An improved form of a camera first tested on Soyuz 22

To further expand its scientific capabilities, Salyut 6 was equipped with 20 portholes for observations, two scientific airlocks to expose equipment to space or eject rubbish, and various pieces of apparatus to carry out biological experiments. Later on during her flight, a Progress spacecraft delivered an external telescope, the KRT-10 radio observatory, which incorporated a directional antenna

s. The antenna was deployed on the rear docking assembly, with the controller remaining inside the station, and was used for both astronomical and meteorological observations.

Support craft



Salyut 6 was primarily supported by the manned Soyuz spacecraft

, which carried out crew rotations and would also have been used in the event of an emergency evacuation. The ferries docked automatically to the station, making use of the new Igla automatic docking system, and were used by departing crews to return to Earth at the end of their flight.

The station was the first to be able to be resupplied by the newly-developed unmanned Progress

 freighters, although they could only dock at the rear port, as the plumbing which allowed the spacecraft to replenish the station's fluids was not available at the front port. The freighters docked automatically to the station via the Igla, and were then opened and emptied by the cosmonauts on board, whilst transfer of fuel to the station took place automatically under supervision from the ground.

In addition to the Soyuz and Progress spacecraft, after her final crew had left, Salyut 6 was visited by an experimental transport logistics spacecraft called Cosmos 1267
