It is the original bag with the initials WCW, which was included in the portable survival kit of Russian cosmonaut Sharipov during his space mission (Expedition 10) onboard the spacecraft Soyuz TMA-5, where he served as the commander. The Soyuz TMA-5 mission was directed to the International Space Station from October 14, 2004, to April 24, 2005. This bag serves as a life preserver in the event of a splashdown of the lander, providing emergency escape and maintaining positive buoyancy for the cosmonaut with the help of inflatable floats.
