CAPE CANAVERAL, Fla. — Space shuttle Atlantis’ rollout to Launch Pad 39A at NASA’s Kennedy Space Center in Florida has been rescheduled to begin at 4 a.m. EDT on Tuesday, March 31, as preparations for the STS-125 mission move forward. Atlantis is targeted to lift off May 12 to service NASA’s Hubble Space Telescope.

NASA Television’s live coverage of the event will begin at 6:30 a.m. Video highlights will air on the NASA TV Video File.

Journalists are invited to a photo opportunity of the shuttle’s move to the pad and an interview opportunity with Atlantis Flow Director Angie Brewer at 8:30 a.m. Tuesday. Dates and times of this event are subject to change. Updates are available by calling 321-867-2525.

Reporters must arrive at Kennedy’s news center by 6:30 a.m. Tuesday for transportation to the viewing area. Media accreditation for this event has closed. Badges can be picked up through Tuesday at the Kennedy Badging Office on State Road 405. The badging office opens at 6 a.m.

The fully assembled space shuttle, consisting of the orbiter, external fuel tank and twin solid rocket boosters is mounted on a mobile launcher platform and will be delivered to the pad atop a crawler-transporter. The crawler will travel slower than 1 mph during the 3.4-mile journey. The process is expected to take approximately six hours.

During Atlantis’ 11-day mission, the crew of seven astronauts will make the final shuttle flight to Hubble. During five spacewalks, they will install two new instruments, repair two inactive ones and replace components. The result will be six working, complementary science instruments with capabilities beyond what is now available, and an extended operational lifespan for the telescope through at least 2014.

Scott Altman will be the commander of Atlantis. Gregory C. Johnson will be the pilot. Mission specialists will be John Grunsfeld, Mike Massimino, Megan McArthur, Andrew Feustel and Michael Good.
