Flight

Launch from the Baikonur Cosmodrome; landing with Soyuz TM-2 spacecraft 80 km northeast of Arkalyk.

After launch the Soyuz TM-3 maneuvered from an initial 231 X 217 km orbit to MIR's 311 x 359 km orbit.
Following a two day solo flight Soyuz TM-3 docked the with the rear port of the MIR space station on July 24, 1987. The spacecraft automatically docked to the Kvant1 port, but they had to use a lever to break the hatch's seal.

Aleksandr Aleksandrov became Aleksandr Laveykin's replacement aboard MIR, becoming Yuri Romanenko's new partner. The visiting expedition observed Syria (Euphrat experiment) and conducted materials processing experiments, but also biological experiments.

Syrian guest cosmonaut Muhammed Faris and Soviet cosmonaut Aleksandr Viktorenko returned to Earth in Soyuz TM-2 with Aleksandr Laveykin, who was diagnosed by ground based doctors as having minor heart problems.

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.

The spacecraft undocked from MIR at 08:34 UTC on July 29, 1987. The Orbital Module was jettisoned before retrofire and left in a 308 x 356 km orbit. Soyuz TM-2 landed at 01:04 UTC with the crew of Muhammed Faris, Aleksandr Laveykin and Aleksandr Viktorenko aboard.

Note

Aleksandr Aleksandrov landed on December 29, 1987 at 09:16 UTC with Soyuz TM-3 spacecraft.
