NASA'S SPACE SHUTTLE PROCESSING STATUS REPORT

Note: NASA's Kennedy Space Center issues Space Shuttle Processing Status Reports periodically 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: http://www nasa gov/centers/kennedy/news/index html

Mission: STS-121 - 18th International Space Station Flight (ULF1 1) - Multi-Purpose Logistics Module Vehicle: Discovery (OV-103) Location: Launch Pad 39B Launch Date: Launch Processing Window July 1-19, 2006 Launch Pad: 39B Crew: Lindsey, Kelly, Sellers, Fossum, Nowak, Wilson and Reiter Inclination/Orbit Altitude: 51 6 degrees/122 nautical miles

Discovery was powered up to support the prelaunch loading this week of hypergolic propellants into the forward and aft reaction control system and the orbital maneuvering system pods Fuel loading for the orbiter's auxiliary power units is scheduled for the weekend Testing of the reaction jet driver - electrical control system for the reaction control system jets - was successfully completed The loading of hypergolic fuel into the solid rocket booster hydraulic power units is scheduled for next week On Monday, the payload bay doors will be opened for payload testing and sensor installation in the Orbiter Boom Sensor System

Mission: STS-115 - 19th International Space Station Flight (12A) - P3/P4 Solar Arrays Vehicle: Atlantis (OV-104) Location: Orbiter Processing Facility Bay 1 Launch Date: No earlier than Aug 28, 2006 Launch Pad: 39B Crew: Jett, Ferguson, Tanner, Burbank, MacLean and Stefanyshyn-Piper Inclination/Orbit Altitude: 51 6 degrees/122 nautical miles

In Orbiter Processing Facility bay 1, Atlantis was powered up this week to support payload testing Early in the week, the auxiliary power controller unit verification testing was successfully completed Preparations for installing engine No 3 are finished, with installation scheduled for Monday Engines No 1 and No 2 already are in place on the orbiter

On Thursday, stacking for STS-115 began with the transfer of the right aft booster segment from the Rotation Processing and Surge Facility to the Vehicle Assembly Building, where it was lifted into high bay 3 and placed on mobile launcher platform No 2 The left aft booster was transported to the Vehicle Assembly Building and lifted into high bay 3 on Friday

Endeavour (OV-105)

Powered-up system testing continues on Endeavour in Orbiter Processing Facility bay 2 following an extensive modification period Main propulsion system leak and functional testing continues, and the potable water leak checks also are ongoing Technicians are performing tests and checkouts of the manipulator positioning mechanisms prior to installing the Orbiter Boom Sensor System The manipulator positioning mechanisms are the pedestals that support the boom inside the payload bay On Thursday, workers finished installing hardware in the rudder speed brake, allowing installation of thermal blankets to begin on the brake The orbiter's drag chute was installed and the drag chute doors will be installed today
