Launch from the Baikonur Cosmodrome; landing
200 km southeast of Dzheskasgan.
Soyuz T-2 was a manned testflight of
the new developed Soyuz T spacecraft. The craft had new engine systems and
could launch three cosmonauts. Additionally, the Soyuz was equipped with a new
Argon computer which controlled docking and reentry procedures. Six unmanned
spacecraft of this new type had been tested before. Following a one day solo
flight Soyuz T-2 docked with the Salyut 6 space station on June 06, 1980 and
common work with the
fourth resident
crew followed.
The main goal of this flight was the testing and
development of onboard systems in the improved Soyuz T series transport vehicle
under piloted conditions. As the craft approached Salyut 6, solar cells,
re-introduced to the Soyuz, were tested. The approach was completed
automatically, while the final 180 metres were achieved manually on June 06,
1980. The Argon docking computer had failed, leaving the craft perpendicular to
the station. The computer failure was later explained as being caused by the
crew and controllers failing to have practiced the particular approach the
computer chose. The crew had therefore chose to dock manually to be safe; the
computer would have successfully docked if allowed to, said the Soviets.
However, failures during the automatic approach was a recurring problem in
future Soyuz T missions.
During their short stay, Yuri
Malyshev and Vladimir
Aksyonov seemed to have carried out a minimum of experiments,
including participating in some medical tests and using the Salyut's
MKF-6M camera. They undocked in the craft they arrived
on only two days after first greeting the resident crew. As they left, the
Salyut turned around and the Soyuz T-2 crew photographed and visually inspected
the space station. The Soyuz then departed and landed about three hours
later.
