The sign accompanying the suit. It reads
Sokol KV-2 Spacesuit
In 1971, three Soviet cosmonauts lost their lives when the Soyuz 11 spacecraft
suffered depressurization in space. They were not wearing space suits. After
that accident, the Soviets began work on a new type of suit that could be worn
for launch and landing, that could protect the cosmonauts from the vacuum of
space in an emergency. (It was not designed for "spacewalks.") This new suit,
the Sokol K, was first used on the mission of Soyuz 12 in September, 1973, and
variants have been used for Soviet/Russion space missions ever since.
The suit on display is a Sokol KV-2, developed for later versions of Soyuz TM
spacecraft. It was used in training by Russian Cosmonaut Aleksandr Kaleri, for
the Soyuz TM-30 mission, which flew to the Mir space station on April 4, 2000.
On June 16, 2000, after 72 days in space, Commander Kaleri and his pilot,
Sergey Zalyotin, left the Mir. They were the last humans to call the Mir home.
The suit was acquired in January 2002, from a dealer in Austria. Its
acquisition was made possible by a generous gift from the Michigan International Speedway.
