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: Vehicle Assembly Building
Launch Date: Launch Planning Window May 15 - June 3, 2005
Launch Pad: 39B
Crew: Collins, Kelly, Noguchi, Robinson, Thomas, Lawrence and Camarda
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

Discovery was rolled from its hanger, Orbiter Processing Facility (OPF) bay 3, to the Vehicle Assembly Building (VAB) on Tuesday, March 29. First motion of the vehicle was at 1:29 a.m. EST. Once Discovery arrived in the VAB, a sling lifted and lowered the vehicle between its twin Solid Rocket Boosters and Discovery was mated, or attached, to its redesigned External Tank.

Mating operations were completed yesterday and the sling was removed from the vehicle. Technicians are currently working final closeouts on the fully assembled Space Shuttle stack. The liquid oxygen and liquid hydrogen electrical mates continue. The installation of a new digital camera in the orbiter is scheduled for today. The Shuttle will be powered up tomorrow for the interface verification test to be performed.

Space Shuttle Discovery could begin its four-mile journey to Launch Pad 39B atop a Crawler Transporter as early as 12 a.m. Tuesday, April 5.

In the Space Station Processing Facility, cargo stowage installation into the MPLM Raffaello continues in preparation for MPLM hatch closure scheduled for mid-April. Raffaello will carry supplies such as food, clothing and spare parts to the International Space Station.

Mission: STS-121 - 18th ISS Flight (ULF1) - Multi-Purpose Logistics Module
Vehicle: Atlantis (OV-104)
Location: Orbiter Processing Facility Bay 1
Launch Date: Launch Planning Window July 12 - July 31, 2005
Launch Pad: 39B
Crew: Lindsey, Kelly, Sellers, Fossum, Nowak and Wilson
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

In OPF bay 1, technicians continue processing Atlantis for its mission to the International Space Station. The commander and pilot seat installation on the flight deck is under way. Space Shuttle Main Engine (SSME) installation began today with an engine for position No. 1 being moved from the SSME Shop to the bay installed in Atlantis. The other two engines are scheduled to be installed later today.

Atlantis' new Orbiter Boom Sensor System (OBSS) is in the Remote Manipulator System lab in the VAB for checkout and final testing before installation in Atlantis. The boom is scheduled to arrive in the bay on April 4 for installation on April 6. 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.

Solid Rocket Booster (SRB) stacking for Atlantis' launch began when the left aft booster was moved from the Rotation Processing and Surge Facility to the VAB yesterday. It will be lifted onto the Mobile Launch Platform early next week. The External Tank remains in the checkout cell for final testing. Following the completion of SRB stacking, the tank will be moved and attached to the SRBs in late April.

Endeavour (OV-105)

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