Space Shuttle Processing Status Report
Note: NASA's Kennedy Space Center issues Space Shuttle Processing Status Reports each week, and is the source for information regarding processing activities associated with the vehicles and payloads. This report does not necessarily reflect the chronological order of future Space Shuttle missions. If you are a member of the media and would like further information, visit

Mission: STS-114 - 17th ISS Flight (LF1) - Multi-Purpose Logistics Module
Vehicle: Discovery (OV-103)
Location: Orbiter Processing Facility Bay 3
Launch Date: Launch Planning Window May 12 - June 3, 2005
Launch Pad: 39B
Crew: Collins, Kelly, Noguchi, Robinson, Thomas, Lawrence and Camarda
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

In Orbiter Processing Facility (OPF) bay 3, processing continues to progress well for Discovery's Return to Flight mission, designated STS-114, to the International Space Station. Orbital Maneuvering System redundant electrical circuit verification testing is complete. Rudder Speed Brake cove panel installation is complete, and work is under way to complete the seal and Thermal Protection System blanket installation.

On Jan. 24, the new Orbiter Boom Sensor System (OBSS) was installed into the starboard side of Discovery's payload bay. Measurements of the boom and Remote Manipulator System camera clearance checks are complete. The 50-foot-long OBSS will attach to the Remote Manipulator System, or Shuttle robotic arm, and is one of the new safety measures for Return to Flight, equipping the orbiter with cameras and laser systems to inspect the Shuttle's Thermal Protection System while in space.

In the Vehicle Assembly Building, the Solid Rocket Boosters for the STS-114 mission are stacked on the Mobile Launcher Platform and final closeouts continue. Right-hand External Tank attach ring foam application is complete. The Return to Flight External Tank, ET-120, is located in the checkout cell and technicians are nearly complete with the electrical checkouts. The External Tank is scheduled to be moved to the integration cell and mated with the Solid Rocket Boosters on Feb. 9.

Mission: STS-121 - 18th ISS Flight (ULF1) - Multi-Purpose Logistics Module/Crew Rotation
Vehicle: Atlantis (OV-104)
Location: Orbiter Processing Facility Bay 1
Launch Date: Launch Planning Window July 12 - August 3, 2005
Launch Pad: 39B
Crew: Lindsey, Kelly, Sellers, Fossum, Nowak and Wilson
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

Technicians continue to process Atlantis in Orbiter Processing Facility bay 1 for its mission to the International Space Station. Preparations are under way to service water coolant loop No. 1, with servicing scheduled for this weekend. The body flap actuator installation continues with three of the four actuators installed.

The left-hand Orbital Maneuvering System (OMS) pod was removed Thursday and will be moved to the Hypergol Maintenance Facility early next week. The pod was removed so that inspections could be performed on the thrusters. Following thorough inspections of the thrusters on another OMS pod, it will be transferred to the bay for installation on the vehicle. The aft flight desk mission and event timer was installed on Wednesday. The drive shafts for the Manipulator Positioning Mechanisms that will support the new Orbiter Boom Sensor System were installed on the starboard side of Atlantis' payload bay.

Endeavour (OV-105)

Space Shuttle Endeavour is in its Orbiter Major Modification period, which began in December 2003.
