Flights

Launch from the Baikonur Cosmodrome; landing 65 km northeast of Arkalyk.

Following a one day solo flight Soyuz T-6 docked manually with the Salyut 7 space station on June 25, 1982 because of problems with the automatic docking systems. Common work with the first resident crew was done.

Several joint Soviet-French scientific research and experiments, including a series of French echography cardiovascular monitoring system experiments, were performed. Jean-Loup Chrétien was the first French and West European astronaut. While aboard the station, the resident crew afforded him the opportunity to eject Salyut 7's weekly bag of waste into space through the station's small trash airlock. Valentin Lebedev, writing in his diary, quoted Jean-Loup Chrétien as saying Salyut 7 "is simple, doesn't look impressive, but is reliable."

The Soyuz spacecraft is composed of three elements attached end-to-end - the Orbital Module, the Descent Module and the Instrumentation/Propulsion Module. The crew occupied the central element, the Descent Module. The other two modules are jettisoned prior to re-entry. They burn up in the atmosphere, so only the Descent Module returned to Earth.
Having shed two-thirds of its mass, the Soyuz reached Entry Interface - a point 400,000 feet above the Earth, where friction due to the thickening atmosphere began to heat its outer surfaces. With only 23 minutes left before it lands on the grassy plains of central Asia, attention in the module turned to slowing its rate of descent.
Eight minutes later, the spacecraft was streaking through the sky at a rate of 755 feet per second. Before it touched down, its speed slowed to only 5 feet per second, and it lands at an even lower speed than that. Several onboard features ensure that the vehicle and crew land safely and in relative comfort.
Four parachutes, deployed 15 minutes before landing, dramatically slowed the vehicle's rate of descent. Two pilot parachutes were the first to be released, and a drogue chute attached to the second one followed immediately after. The drogue, measuring 24 square meters (258 square feet) in area, slowed the rate of descent from 755 feet per second to 262 feet per second.
The main parachute was the last to emerge. It is the largest chute, with a surface area of 10,764 square feet. Its harnesses shifted the vehicle's attitude to a 30-degree angle relative to the ground, dissipating heat, and then shifted it again to a straight vertical descent prior to landing.
The main chute slowed the Soyuz to a descent rate of only 24 feet per second, which is still too fast for a comfortable landing. One second before touchdown, two sets of three small engines on the bottom of the vehicle fired, slowing the vehicle to soften the landing.
