Two astronauts and a cosmonaut, all mission specialists, float onboard Spacehab. They are astronauts Daniel C. Burbank (top left) and Richard A. Mastracchio (top right), along with cosmonaut Yuri I. Malenchenko. The Spacehab double module is as 'empty' as it was at any other time during the STS-106 mission in this scene, photographed during mission's end. The seven-man crew had moved a large amount of supplies and hardware to the International Space Station (ISS).
