Mission: STS-117 - 21st International Space Station Flight (13A) -
S3/S4 Truss Segment Solar Arrays
Vehicle: Atlantis (OV-104)
Location: Launch Pad 39A
Launch Date: Targeted for March 15, 2007
Launch Pad: 39A
Crew: Sturckow, Archambault, Reilly, Swanson, Forrester and Olivas
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

The STS-117 crew arrived at Kennedy Space Center Wednesday to
participate in the Terminal Countdown Demonstration Test (TCDT), a
launch dress rehearsal. The rehearsal includes emergency egress
training at the launch pad and a practice run of the final launch
countdown, during which the crew climbs aboard Atlantis and executes
the checklist for the final hours of the simulated countdown.

Earlier in the week, the STS-117 payload was installed into Atlantis'
cargo bay. In addition, technicians continued their preparations for
the hypergolic propellant load, scheduled for next week. Shuttle
interface testing and validation testing of launch pad systems are
also under way.

Mission: STS-118 - 22nd International Space Station Flight (13A.1) -
S5 Truss Segment
Vehicle: Endeavour (OV-105)
Location: Orbiter Processing Facility Bay 2
Launch Date: Targeted for June 28, 2007
Launch Pad: 39A
Crew: Kelly, Hobaugh, Williams, Morgan, Mastracchio, Caldwell and
Anderson
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

Endeavour remains in Orbiter Processing Facility bay 2, and
technicians continue preparing the vehicle for its first launch in
more than four years. The vehicle has undergone an extensive
modification period, including the addition of all of the
return-to-flight safety upgrades added to both Discovery and
Atlantis.

This week, technicians completed preparations for the mating of the
aft orbital maneuvering system pod to the reaction control system.
Final mate and interface verification is scheduled for the weekend.
Work is also under way to prepare the orbiter for installation of the
orbiter boom sensor system, which is a robotic arm extension. Final
testing of the orbiter's fuel cells was completed this week.

Mission: STS-122
Vehicle: Discovery

Processing of Discovery, which returned from the STS-116 mission on
Dec. 22, continues in Orbiter Processing Facility bay 3. The
right-hand orbital maneuvering system pod was removed this week.
Technicians are busy working on Discovery's electrical system,
preparing for the installation of the new station-to-shuttle power
transfer system (SSPTS) modification. This system will allow the
orbiter and International Space Station to share power, which will
enable the orbiter to remain docked for longer periods of time. Work
is also under way to change out Discovery's cockpit windows, with the
removal and replacement of window No. 8 completed this week.
