In Orbiter Processing Facility bay 2, during crew equipment interface test activities, STS-118 crew members get a close look at the orbiter boom sensor system in Endeavour's payload bay. At center are Commander Scott Kelly and Mission Specialist Barbara Morgan. The STS-118 mission will be delivering the third starboard truss segment, the ITS S5, to the International Space Station, as well as the SPACEHAB single cargo module filled with supplies and equipment.
