As launch preparations resumed at NASA's Kennedy Space Center's Launch Pad 39B on Thursday, mission managers set Sept. 6 as the new date for the launch of Atlantis on Mission STS-115 to the International Space Station. Liftoff time would be 12:29 p.m. EDT.
No damage to facilities or flight hardware is reported at the Kennedy Space Center following the exit of Ernesto from Florida. As the tropical depression passed through the area on Wednesday, the peak wind recorded on Launch Pad 39B, where Space Shuttle Atlantis stands, was measured at 44 miles per hour at 4:45 p.m. EDT. The shuttle was surrounded by the rotating service structure as NASA decided to protect it in place when weather forecasts improved.
On Tuesday, mission managers halted a rollback of the space shuttle to the protection of the Vehicle Assembly Building as the projected path of the tropical storm skirted further west than first expected, allowing a sufficient decrease in winds to permit the shuttle to ride out the storm at the pad.
The STS-115 crew consists of Commander Brent W. Jett Jr., Pilot Christopher J. Ferguson and Mission Specialists Heidemarie M. Stefanyshyn-Piper, Joseph R. Tanner, Daniel C. Burbank and Steven G. MacLean, who represents the Canadian Space Agency.
With this mission, NASA is ready to get back to building the International Space Station, marking the first time in almost four years that a space station component has been added to the orbiting outpost. That also means the shuttle program is coming up on some of the most challenging space missions ever.
During their three spacewalks, crew members of Atlantis will install the P3/P4 integrated truss and a second set of solar arrays on the space station, doubling the station's current ability to generate power from sunlight and adding 17.5 tons to its mass.
