BEREZOVOY ON PRESSURIZED PANTS.
Autograph Manuscript Signed ("A. Berezovoy"), 2 pp recto and verso, 11 x 7½ inches, on grid paper.
Berezovoy spent 211 days on the space station Salyut 7 in 1982. One side of this manuscript is a lengthy description of the purpose of the "Karkas" ("Skeleton") compression trousers that Berezovoy wore on his return flight to Earth in Soyuz T-7 on December 10. They were a critical part of flight attire for cosmonauts who had been in space for longer than 30 days. Their extremely tight fit prevented excess blood from flowing to the lower body during the descent to Earth, when G-forces reached 5 or 6 Gs. He explains that the trousers would also be worn for the first few days back on terra firm as the body adjusted to gravity. The reverse of the document, dated November 5, 1987, is a list of "Dynamic Regimes" relating to the Mir space station.
