KENNEDY SPACE CENTER, FLA. -- On Launch Pad 39A at NASA's Kennedy Space Center, the rotating service structure is rolling on its axis to uncover space shuttle Endeavour. First motion was at 8:23 a.m. and rollback was complete at 8:55 a.m. The structure provides protected access to the orbiter for changeout and servicing of payloads at the pad. The structure is supported by a rotating bridge that pivots about a vertical axis on the west side of the pad's flame trench. After the RSS is rolled back, the orbiter is ready for fuel cell activation and external tank cryogenic propellant loading operations. The pad is cleared to the perimeter gate for operations to fill the external tank with about 500,000 gallons of cryogenic propellants used by the shuttle’s main engines. This is done at the pad approximately eight hours before the scheduled launch. Endeavour and its crew will deliver the first section of the Japan Aerospace Exploration Agency's Kibo laboratory and the Canadian Space Agency's two-armed robotic system, Dextre.

CAPE CANAVERAL, Fla. - In Orbiter Processing Facility 1 at NASA's Kennedy Space Center in Florida, United Space Alliance technicians roll the test equipment away from an external tank door on space shuttle Atlantis following the successful completion of a push test. Two umbilical doors, located on the shuttle's aft fuselage, close after external tank separation following launch. The test confirms that the door's actuators are functioning properly and that signals sent from the actuators correctly indicate that the doors have closed, creating the necessary thermal barrier for reentry. Atlantis is next slated to deliver an Integrated Cargo Carrier and Russian-built Mini Research Module to the International Space Station on the STS-132 mission.

CAPE CANAVERAL, Fla. -- In the Press Site auditorium at NASA's Kennedy Space Center in Florida, Shuttle Launch Director Mike Leinbach briefs media about the launch status of space shuttle Endeavour's STS-134 mission and announces a new launch date. Technicians replaced and tested the aft load control assembly-2 (ALCA-2) and wiring located in Endeavour's aft avionics bay 5. ALCA-2 distributes power to nine shuttle systems and is believed to have caused fuel line heaters for Endeavour's auxiliary power unit-1 (APU-1) to fail April 29 during the first launch attempt. Launch now is scheduled for May 16 at 8:56 a.m. EDT. Endeavour and its crew will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer-2 (AMS), a high-pressure gas tank and additional spare parts for the Dextre robotic helper to the station.

The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate an orbiter's cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiter's atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. Because the orbiter is unpowered during re-entry and landing, its high-speed glide must be perfectly executed the first time. The crew for space shuttle Endeavour's STS-123 mission is at Kennedy for a full launch dress rehearsal, known as the terminal countdown demonstration test or TCDT. The terminal countdown demonstration test provides astronauts and ground crews with an opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency training. Endeavour is targeted to launch March 11 at 2:28 a.m. EDT on a 16-day mission to the International Space Station. On the mission, Endeavour and its crew will deliver the first section of the Japan Aerospace Exploration Agency's Kibo laboratory and the Canadian Space Agency's two-armed robotic system, Dextre.

CAPE CANAVERAL, Fla. -- STS-134 Pilot Greg H. Johnson talks to media as the space shuttle that will take Johnson and his crewmates to the International Space Station slowly rolls past. Endeavour began its move from High Bay 3 in the Vehicle Assembly Building to Launch Pad 39A at NASA's Kennedy Space Center in Florida at 7:56 p.m. EST. The 3.4-mile trek, known as "rollout," will take about seven hours to complete. This is the final scheduled rollout for Endeavour, which is attached to its external fuel tank and solid rocket boosters atop a crawler-transporter. STS-134 crew members will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer-2 (AMS), a high-pressure gas tank, additional spare parts for the Dextre robotic helper and micrometeoroid debris shields to the orbiting outpost on the shuttle's final spaceflight.
