STS081-E-05145 (13 Jan. 1997) --- Astronaut John M. Grunsfeld, mission specialist, works with a Passive Thermal Conditioning Unit (PTCU), the cylindrical device suspended between the mission specialist and the nearby biorack glovebox onboard the Spacehab Double Module (DM). He holds a container of experiment samples in his left hand. This image was recorded with an Electronic Still Camera (ESC) and was later downlinked to flight controllers in Houston, Texas. Grunsfeld and five astronaut crew mates are preparing for a scheduled mid-week docking with Russia's Mir Space Station.
