Cargo bay and aft section of the Space Shuttle orbiter Columbia photographed through the flight deck's aft windows. In the lower right corner is one of the vehicle's radiator panels. Some of the thermal tiles are missing from the orbital maneuvering system OMS pods which flank the vertical stabilizer at left edge of the photograph. A collection of possible support equipment is housed in the box-like devices lower left known as the development flight instrument pallet. The pentagon-shaped glare at upper left is caused by window reflection.
