NASA’s space shuttle fleet is housed and processed at Kennedy Space
Center, Fla.

Mission: STS-121 - 18th ISS Flight (ULF1.1) - Multi-Purpose Logistics
Vehicle: Discovery (OV-103)
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
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

Thermal protection system blanket installation continues on the
orbiter boom sensor system. The sensor package was installed Tuesday
on the boom.

Engineers are analyzing information and hardware following failed leak
checks of shuttle main engines number 2 and 3. The two are in the
main engine processing facility for evaluations. The engines will be
reinstalled in the vehicle when analysis is completed; tentatively
set for early next week.

In the Vehicle Assembly Building, solid rocket booster stacking
continues today; the left aft center segment is being lifted onto the
stack on the mobile launcher platform. Right booster stacking is
scheduled for mid-February completion; left booster by the end of the

Endeavour (OV-105)

In Orbiter Processing Facility bay 2, standard mission processing
continues and return-to-flight modifications. Heads-up display
alignment is scheduled for the commander’s seat this weekend and
pilot’s seat next week. The display is an optical mini-processor that
cues the commander and/or pilot during the final phase of atmosphere
re-entry and during the final approach to the runway.

Mission: STS-115 - 19th ISS Flight (12A) - P3/P4 Solar Arrays
Vehicle: Atlantis (OV-104) Location: Orbiter Processing Facility
Bay 1 Launch Date: To be determined Launch Pad: 39B Crew: Jett,
Ferguson, Tanner, Burbank, MacLean and Stefanyshyn-Piper
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

Atlantis is in a power-down period. More than 400 gap fillers have
been removed and replaced on the shuttle underside. When gap filler
work is completed on Discovery, the entire team will move to Atlantis
to continue the work at approximately 350 fillers weekly. New
installation procedures were developed to ensure the gap fillers stay
in place and do not pose any hazard on atmosphere re-entry.
