NASA CHANGES 2008 SHUTTLE TARGET LAUNCH DATES, SCHEDULES TCDT

HOUSTON - NASA has adjusted the target launch dates for the two remaining space shuttle missions in 2008 Shuttle Atlantis' STS-125 mission to the Hubble Space Telescope is targeted for Oct 10, while Endeavour's STS-126 supply mission to the International Space Station has moved to Nov 12

Shuttle managers made the decision after Atlantis was rolled to the launch pad and the effects of Tropical Storm Hanna were beyond NASA's Kennedy Space Center in Florida That allowed managers to more accurately assess the impacts of recent tropical systems on the launch schedule

Atlantis began rolling from Kennedy's Vehicle Assembly Building to Launch Pad 39A Thursday at 9:19 a m EDT The shuttle arrived at the pad at approximately 2 p m and was secured at 3:52 p m Atlantis now is targeted to launch at approximately 12:33 a m EDT, Friday, Oct 10 NASA Television coverage of launch will begin at 7:30 p m EDT on Thursday, Oct 9 The 11-day flight will include five spacewalks to repair and upgrade the Hubble telescope Atlantis is scheduled to land at approximately 10:21 p m , Oct 20

Scott Altman will command STS-125, with Gregory C Johnson serving as pilot Mission specialists include veteran spacewalkers John Grunsfeld and Mike Massimino, and first-time space fliers Andrew Feustel, Michael Good and Megan McArthur

Endeavour will close 2008 with a 15-day mission to deliver supplies and cargo to the space station During the STS-126 mission, NASA astronaut Sandra Magnus will replace Greg Chamitoff as an Expedition 18 crew member on the station Chamitoff will return to Earth after five months in space The mission's targeted launch time is 8:43 p m EST, Nov 12 Landing will occur at approximately 2:45 p m , Nov 27

Chris Ferguson will command STS-126, with Eric Boe serving as pilot Mission specialists will be Steve Bowen, Shane Kimbrough, Heidemarie Stefanyshyn-Piper, Donald Pettit, Magnus and Chamitoff

The formal launch dates for space shuttle flights are determined during the Flight Readiness Review, which is conducted about two weeks before launch The STS-125 review is scheduled for Sept 22-23 The review for STS-126 is scheduled for Oct 30

An STS-125 launch dress rehearsal, known as the terminal countdown demonstration test, or TCDT, is scheduled to take place at Kennedy Sept 22-24 The test provides each shuttle crew with an opportunity to participate in simulated countdown activities, including equipment familiarization and emergency training
