Launch vehicle:  Soyuz-U (No. Ts15000-276)
Spacecraft:  Soyuz T-7 (7K-ST No. 12L)


Launch from the Baikonur Cosmodrome and landing with Soyuz T-5 spacecraft 70 km northeast of Arkalyk .

Following a one-day solo flight Soyuz T-7 docked with the Salyut 7 space station on August 20, 1982.

During the next five days the crew performed common work with the first resident crew. The crew delivered experiments and mail to the station. The crew also conducted scientific and technical research and experiments, especially in the field of microgravity.

Svetlana Savitskaya was the first woman to visit space in 20 years, and was included in the crew specifically to upstage the Americans from accomplishing the same feat. She was given the orbital module of Soyuz T-7 for privacy. The Soyuz T-7 crew delivered experiments and mail from home to the first resident crew of Salyut 7 crew. On August 21, 1982 the five cosmonauts traded seat liners between the Soyuz-T's. The Soyuz T-7 crew undocked in Soyuz T-5, leaving the newer Soyuz T-7 spacecraft as a lifeboat for the long-duration crew.

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.
The deorbit burn lasted about 3 to 4 minutes. Having shed two-thirds of its mass, the Soyuz reached Entry Interface - a point 400,000 feet (121.9 kilometers) 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 (230 meters) per second. Before it touched down, its speed slowed to only 5 feet (1.5 meter) 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 (230 meters) per second to 262 feet (80 meters) per second.
The main parachute was the last to emerge. It is the largest chute, with a surface area of 10,764 square feet (1,000 square meters). 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 (7.3 meters) 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.
