NASA’S SPACE SHUTTLE PROCESSING STATUS REPORT: S06-004

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
Module
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

The forward reaction control system is scheduled to be delivered to
the bay next week for installation into the vehicle. The control
system provides the thrust for attitude (rotational) maneuvers
(pitch, yaw and roll) and for small velocity changes along the
orbiter axis.

Following shuttle main engine installation, leak checks were performed
on the interfaces per standard procedure. Engines No. 2 and 3 did not
pass the leak check. Those two engines were removed from the vehicle
and were returned to the main engine processing facility for
evaluations. Technicians in the engine facility will lap, or polish,
the engine interfaces to remove any possible microscopic
imperfections. Once completed, the engines will be reinstalled into
the vehicle and leak checks repeated. The additional work will not
impact the overall processing schedule.

In the Vehicle Assembly Building, solid rocket booster stacking was
placed on hold until Monday due to an issue with the 325-ton crane
controller. Booster stacking is scheduled to be complete on the right
booster in mid-February and the left booster by the end of the month.
At this time, the additional work will not impact the overall
processing schedule.

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

Preparations continue for the installation of the orbiter boom sensor
system inside the payload bay. About 200 gap fillers have been
removed and replaced on the underside of Atlantis. Once gap filler
work is completed on Discovery, the entire gap filler team will move
to Atlantis to continue the work at a rate of about 350 gap fillers
per week. New installation procedures were developed to ensure the
gap fillers stay in place and do not pose any hazard on re-entry to
the atmosphere.

Endeavour (OV-105)

In Orbiter Processing Facility bay 2, processing continues on
Endeavour following an extensive modification period. On Jan. 27, the
vehicle was powered up to support system testing. Body flap hardware
reinstallation continues.

Thermal protection system blanket installation continues in the nose
cap. Nose cap installation for flight is planned for late February.
Work continues on the new modification called the “station to shuttle
power transfer system,” which will allow the shuttle to remain docked
to the station longer.
