Mission: STS-118 - 22nd International Space Station Flight - S5 Truss Segment
Vehicle: Endeavour (OV-105)
Official Launch Date: Aug. 8, 2007
Official KSC Landing Date: Aug. 21, 2007
Crew: Kelly, Hobaugh, Williams, Morgan, Mastracchio, Caldwell and Drew
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

Endeavour touched down at Kennedy Space Center at 12:32 p.m. EST on Aug. 21, completing a 13-day journey to the International Space Station. The mission was cut short by a day because of the potential threat to the Houston area posed by Hurricane Dean. Prior to the Sunday undocking from the station, Mission Specialist Dave Williams and station Flight Engineer Clay Anderson conducted the final spacewalk of the mission on Saturday. They installed the external wireless instrumentation system antenna, attached a stand for the shuttle's robotic arm extension boom and retrieved two materials experiment containers. The spacewalk was trimmed by two hours to allow for a day-early hatch closing. Endeavour is now in Orbital Processing Facility bay No. 2, where post-flight inspections and processing are under way. Endeavour's payload will be removed this weekend.

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. 23, 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 this week, forward, midbody and aft closeout work continues. Final payload bay door closing is scheduled for next week. The orbiter docking system pyro testing is under way. The external door functional testing is complete, as is final testing of the engine cutoff sensor wiring modifications.

Stacking and closeout of the STS-120 solid rocket boosters in the Vehicle Assembly Building has finished. Mating of the external tank to the boosters has been postponed, pending completion of foam repair work that will be done on the tank's liquid oxygen feedline support brackets.

Mission: STS-122 - 24th International Space Station Flight - Columbus 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, technicians continue making modifications to the orbiter's engine cutoff sensor wiring. This work involves rerouting new wires and installing new resistors. Workers also continued installing new, stronger tiles, known as Boeing Reusable Insulation (BRI) tiles, around the main landing gear doors. Installation of the main propulsion system tanks is complete, with leak checks planned next week. Waterproofing of the orbiter's thermal protection system is planned for Sunday. The left-hand orbital maneuvering system pod was removed to allow for a valve replacement.
