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, final launch preparations continue. The payload bay doors were closed for flight last night, and loading of the fuel for the power reactant storage and distribution system is now under way. Weather delays interrupted the PRSD loading earlier this afternoon, but the task is expected to be completed later this evening. No impact to the remaining schedule is expected. Also, the Tyvek ring covers have been installed on the forward reaction control system thrusters. These covers protect the thrusters from inclement weather. They are designed to release from the orbiter shortly after launch, as the shuttle clears the tower.
Mission managers met at KSC this afternoon to further discuss progress made and give final approval to continue with launch activities. No problems were discussed that would prevent an on-time launch on Sunday.
Weather forecasters indicate the launch day probability of weather prohibiting launch is 40 percent. A Bermuda high pressure ridge located over the Florida Straits is creating a southwesterly flow over Central Florida, bringing afternoon thunderstorms for the next two days. The primary concerns on Sunday are anvil clouds, showers and thunderstorms within 20 nautical miles of the Shuttle Landing Facility.
