RELEASE : S04-12
Space Shuttle Processing Status Report: S04-12
The Space Shuttle fleet is housed and processed at NASA's Kennedy Space Center (KSC), Fla. The order the Space Shuttles are listed in this report does not necessarily reflect the chronological order of future missions.

Discovery (OV-103)

Processing of Discovery continues in the Orbiter Processing Facility (OPF) for its Return to Flight mission, STS-114, to the International Space Station (ISS). Following the installation of the left-hand Orbital Maneuvering System pod on the vehicle, technicians began installing the thrusters.

The Forward Reaction Control System is scheduled for delivery to the OPF early next week. The four Rudder Speed Brake (RSB) actuators and panels have been reinstalled on the vehicle following a complete inspection, bead blasting and painting of the panels. Bead blasting is a process using a pressurized pneumatic gun containing silica carbide, plastic pellets or glass beads to remove primer, paint and corrosion from orbiter vehicle surfaces.

Atlantis (OV-104)

Atlantis was powered up in support of mission processing for its future flight to the ISS. The four RSB actuators were removed from the vehicle and X-rayed at the Titan X-ray Facility at Cape Canaveral Air Force Station. All four actuators showed the gears were assembled in the proper orientation. At the vendor, the actuators are undergoing a complete inspection. Thermal Protection System blanket installation continues on Reinforced Carbon-Carbon nose cap. The nose cap was removed from the vehicle and sent back to the vendor for thorough Non-Destructive Engineering evaluation and recoating. The blankets are being reinstalled prior to technicians re-hanging the nose cap on the vehicle.

Endeavour (OV-105)

Endeavour is in its Orbiter Major Modification period, which began in December 2003. Electrical modifications continue in the crew module. Wire inspections are ongoing in the Environmental Control and Life Support System bay.

Right-hand radiator No. 1 installation is scheduled for today, with right-hand radiator No. 2 scheduled for no earlier than the middle of next week.
