CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, a crawler-transporter keeps space shuttle Endeavour level as it travels up the five percent grade to the base of Launch Pad 39A. First motion on the 3.4-mile trip from the Vehicle Assembly Building, known as rollout, was at 4:13 a.m. EST Jan. 6. Endeavour was secure or "hard down" on the pad at 10:37 a.m. Rollout is a significant milestone in launch processing activities. The primary payload for the STS-130 mission is the International Space Station's Node 3, Tranquility, a pressurized module that will provide room for many of the station's life support systems. Attached to one end of Tranquility is a cupola, a unique work area with six windows on its sides and one on top. The cupola resembles a circular bay window and will provide a vastly improved view of the station's exterior. The multi-directional view will allow the crew to monitor spacewalks and docking operations, as well as provide a spectacular view of Earth and other celestial objects. The module was built in Turin, Italy, by Thales Alenia Space for the European Space Agency. Endeavour's STS-130 launch is targeted for 4:39 a.m. EST Feb. 7.

CAPE CANAVERAL, Fla. - At NASA's Kennedy Space Center in Florida, space shuttle Endeavour begins rolling off Launch Pad 39B for the 3.4-mile rollaround to Launch Pad 39A. First motion was at 8:28 a.m. EDT. To the left is the open rotating service structure with the Payload Changeout Room and the fixed service structure with the 80-foot-tall lightning mast on top. Endeavour is targeted to launch Nov. 14 on the STS-126 mission. On this 27th mission to the International Space Station, Endeavour will carry the Lightweight Multi-Purpose Experiment Support Structure Carrier and the Multi-Purpose Logistics Module Leonardo that will hold supplies and equipment, including additional crew quarters, additional exercise equipment, spare hardware and equipment for the regenerative life support system.

KENNEDY SPACE CENTER, FLA. -- In the early morning, the payload canister containing the Chandra X-ray Observatory, with umbilical hoses still attached, is lifted up the Rotating Service Structure (RSS). The hoses provide a controlled environment during the transfer. The canister arrived at the pad on the payload canister transporter below it. The canister will be lifted up to the Payload Changeout Room in the RSS where it will be relieved of its cargo. After the RSS rotates to a position behind Space Shuttle Columbia (at right), the observatory will then be installed vertically in the orbiter payload bay. The world's most powerful X-ray telescope, Chandra will allow scientists from around the world to see previously invisible black holes and high-temperature gas clouds, giving the observatory the potential to rewrite the books on the structure and evolution of our universe. Chandra is the primary payload on mission STS-93, scheduled to launch no earlier than July 20 aboard Space Shuttle Columbia (right) KSC-99pp0770

KENNEDY SPACE CENTER, FLA. - The rotating service structure (left) on Launch Pad 39B is ready to roll away from Space Shuttle Atlantis in preparation for launch. The RSS provides protected access to the orbiter for changeout and servicing of payloads at the pad and then is rolled away before liftoff. Atlantis is scheduled to launch Sept. 6 at 12:29 p.m. EDT on mission STS-115. During the mission, Atlantis' astronauts will deliver and install the 17.5-ton, bus-sized P3/P4 integrated truss segment on the station. The girder-like truss includes a set of giant solar arrays, batteries and associated electronics and will provide one-fourth of the total power-generation capability for the completed station. This mission is the 116th space shuttle flight, the 27th flight for orbiter Atlantis, and the 19th U.S. flight to the International Space Station. STS-115 is scheduled to last 11 days with a planned KSC landing at about 8:03 a.m. EDT on Sept. 17. Photo credit: NASA/George Shelton KSC-06pd2037

CAPE CANAVERAL, Fla. -- Employees check out space shuttle Atlantis after it was uncovered on Launch Pad 39A at NASA's Kennedy Space Center in Florida following the move of the rotating service structure (RSS). The structure provides weather protection and access to the shuttle while it awaits liftoff on the pad. RSS "rollback" marks a major milestone in Atlantis' STS-135 mission countdown. Atlantis and its crew of four; Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandy Magnus and Rex Walheim, are scheduled to lift off at 11:26 a.m. EDT on July 8 to deliver the Raffaello multi-purpose logistics module packed with supplies and spare parts to the International Space Station. Atlantis also will fly the Robotic Refueling Mission experiment that will investigate the potential for robotically refueling existing satellites in orbit. In addition, Atlantis will return with a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems. STS-135 will be the 33rd flight of Atlantis, the 37th shuttle mission to the space station, and the 135th and final mission of NASA's Space Shuttle Program.

Space Shuttle Program

The Space Shuttle program was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972. The Space Shuttle system—composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank— carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO). When its mission was complete, the orbiter would re-enter the Earth's atmosphere and lands as a glider. Although the concept had been explored since the late 1960s, the program formally commenced in 1972 and was the focus of NASA's manned operations after the final Apollo and Skylab flights in the mid-1970s. It started with the launch of the first shuttle Columbia on April 12, 1981, on STS-1. and finished with its last mission, STS-135 flown by Atlantis, in July 2011.
