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:

Mission: STS-115 - 19th International Space Station Flight (12A) - P3/P4 Truss Segment and Solar Arrays
Vehicle: Atlantis (OV-104)
Location: Launch Pad 39B
Launch Date: Aug. 27, 2006, 4:30 p.m. EDT
Crew: Jett, Ferguson, Tanner, Burbank, MacLean and Stefanyshyn-Piper
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

At Launch Pad 39B, workers have completed hypergolic propellant loading of the orbiter and solid rocket boosters. Following a decision by Space Shuttle Program managers to remove and replace two Ku-band antenna actuator bolts in the forward section of the orbiter payload bay, workers spent the weekend preparing access platforms, performing the bolt replacement and then removing the temporary access equipment. The bolt replacement was completed early Sunday. Later on Sunday, the orbiter's payload bay doors were closed and ordnance installation was initiated, with completion early on Monday. Technicians are now closing out the orbiter's aft compartments and pressurization of the orbiter's maneuvering system, reaction control system and main propulsion system will begin tomorrow. Stowage of flight crew equipment in the crew module is ongoing.

In Houston, the STS-115 crew began their health stabilization period in preparation for the Aug. 27 launch.
