CAPE CANAVERAL, Fla. - The space shuttle Atlantis arrived at its launch pad at NASA's Kennedy Space Center, Fla., at 3:09 p.m. EST on top of the giant vehicle known as the crawler transporter. The next milestone for the upcoming mission, STS-117, is a full launch dress rehearsal as the six-member crew prepares to continue building the International Space Station.

The crawler transporter began carrying Atlantis out of Kennedy's Vehicle Assembly Building at 8:19 a.m. It traveled just under 1 mph during the 3.4 mile journey.

While at the pad, the shuttle will undergo final testing, payload installation and a "hot fire" test of auxiliary power units. When testing is completed, the rotating service structure will be moved around the vehicle for protection.

Atlantis' targeted launch date is March 15. During the 11-day mission, the crew will install a new truss segment, retract a set of solar arrays and unfold a new set on the starboard side of the station. The launch marks the first liftoff from Pad 39A in four years.

The astronauts and ground crews for the mission will participate in a launch dress rehearsal, known as the terminal countdown demonstration test, Feb. 21 to 23 at Kennedy. The test provides the crew of each shuttle mission with an opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency egress training.

Permanently badged media interested in attending the demonstration test events should contact the Kennedy News Center at 321-867-2468 by 4 p.m. Feb. 20. If media have been approved to cover the STS-117 mission, there is no need to reapply for credentials for the demonstration test events. STS-117 mission badges will be available for pick up beginning Feb. 21 from 8 a.m. to noon at the NASA Pass and Identification Building on State Road 3.

Accreditation for foreign news media for this event is closed. U.S. media without Kennedy credentials may apply for accreditation online through 4 p.m. Feb. 20 at: https://media.ksc.nasa.gov

The crew includes Commander Rick Sturckow, Pilot Lee Archambault and mission specialists Jim Reilly, Patrick Forrester, Steven Swanson and John "Danny" Olivas.
