NASA's Space Shuttle Processing Status Report
Note: NASA's Kennedy Space Center issues Space Shuttle Processing Status Reports each week, and is the source for information regarding processing activities associated with the vehicles and payloads. This report does not necessarily reflect the chronological order of future Space Shuttle missions. If you are a member of the media and would like further information, visit

Discovery (OV-103)

Mission: STS-121 - 18th International Space Station Flight, second test mission
Payload: Multi-Purpose Logistics Module
Location: Orbiter Processing Facility Bay 3
Launch Date: No earlier than May 2006
Launch Pad: 39B
Crew: Lindsey, Kelly, Sellers, Fossum, Nowak, Wilson and Reiter

Main landing gear wheel and tire assembly and installation are complete. Pyrotechnic connection completed this week, and the drag chute installed. Water spray boilers No. 1 and 3 were serviced and are both undergoing a 24-hour decay check.

Atlantis (OV-104)

Mission: STS-115 - 19th International Space Station Flight
Payload: P3/P4 Solar Arrays
Location: Orbiter Processing Facility bay 1
Launch Date: TBD
Launch Pad: 39B
Crew: Jett, Ferguson, Tanner, Burbank, MacLean and Stefanyshyn-Piper

S-band antenna installation complete. Thermal protection system gap filler inspections and rework continue in the forward and mid-body areas. All zones are identified and mapping is complete in three of the 10 zones. Mapping will be complete in all zones by Thanksgiving and pull tests will begin. This work is being performed due to two gap fillers protruding from the underside of Discovery on the first return to flight mission, STS-114.

Endeavour (OV-105)

In Orbiter Processing Facility bay 2, the orbiter continues processing following a nearly two-year major modification period. In the payload bay, drive shaft installation on manipulator positioning mechanisms is under way. The mechanisms are the pedestals that hold the remote manipulator system, or shuttle arm, in the payload bay.

Work continues to reinstall both the body flap and the rudder speed brake. The speed brake was removed to ensure the gears in the actuators were installed in the proper configuration prior to flight.
