NASA's Space Shuttle Processing Status Report
Note: NASA's Kennedy Space Center issues Space Shuttle Processing Status Reports periodically and is the source for information regarding processing activities associated with the vehicles and payloads. If you are a member of the media and would like further information, visit:

Mission: STS-118 - 22nd International Space Station Flight - S5 Truss Segment
Vehicle: Endeavour (OV-105)
Location: Launch Complex 39A
Launch Date: Targeted for Aug. 7, 2007
Crew: Kelly, Hobaugh, Williams, Morgan, Mastracchio, Caldwell and Drew
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

Shortly after 8 p.m. Monday, Endeavour rolled out of the Vehicle Assembly Building, arriving at Launch Pad 39A about seven hours later. Connection of the shuttle and mobile launch platform systems to the pad systems immediately began, and validation of the systems is complete. A test firing of the auxiliary power units on the orbiter showed that they operated normally. Following this hot fire test, the rotating service structure was moved into the mate position, wrapping around the orbiter to provide weather protection and access for workers. Checkouts of the shuttle systems are under way. The hydraulic main engine and aerosurface frequency response test is complete.

The orbiter payload bay doors will be opened tonight, with payload installation scheduled for Sunday.

Mission: STS-120 - 23rd International Space Station Flight - U.S. Node 2
Vehicle: Discovery (OV-103)
Location: Orbiter Processing Facility Bay 3
Launch Date: Targeted for Oct. 20, 2007
Launch Pad: 39A
Crew: Melroy, Zamka, Parazynski, Wheelock, Wilson, Nespoli and Tani
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

In Orbiter Processing Facility bay No. 3, checkout of the flash evaporator system heater is complete. Testing of the engine cutoff sensor system, payload pre-mate testing and rigging of the latching mechanism for the orbiter boom sensor system are all under way. Workers are preparing the orbiter for installation of two of the three engines, scheduled for this weekend.

Stacking of the STS-120 solid rocket boosters in the Vehicle Assembly Building is scheduled to begin next week.

Mission: STS-122 - 24th International Space Station Flight - Columbus Laboratory Module
Vehicle: Atlantis (OV-104)
Location: Orbiter Processing Facility Bay 1
Launch Date: Targeted for Dec. 6, 2007
Launch Pad: 39A
Crew: Frick, Poindexter, Schlegel, Eyharts, Love, Melvin and Walheim
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

In Orbiter Processing Facility bay No. 1, overall inspection of the orbiter's thermal protection system is about 80 percent complete. This includes thermography inspection of the left and right wing reinforced carbon-carbon panels, along with the chin panel and nose cap. The main landing gear tires have been removed, the strongbacks were installed on the payload bay doors, and the doors have been opened. The forward reaction control system thruster and vernier inspection began this week, as did removal of the main engine dome heat shields. Preparations for engine removal are under way.
