Bay 3 at NASA's Kennedy Space Center in Florida removed from Discovery is lowered toward a storage platform.

In Orbiter Processing Facility bay 3 at NASA's Kennedy Space Center in Florida, the remote manipulator system, or RMS, removed from space shuttle Discovery is lowered toward a storage platform. The RMS is used to grab, or grapple, the payload as well as retrieve, repair and deploy satellites; provide a mobile extension ladder for spacewalking crewmembers; and be used as an inspection aid to allow flight crew members to view the orbiter’s or payload’s surfaces through a TV camera on the arm. Discovery is targeted to launch Aug. 6 on the STS-128 mission. Photo credit: NASA/Jack Pfaller
