CAPE CANAVERAL, Fla. -- A canister, carrying the Alpha Magnetic Spectrometer-2 (AMS) and Express Logistics Carrier-3 for space shuttle Endeavour's STS-134 mission, arrives at Launch Pad 39A at NASA's Kennedy Space Center in Florida. Next, crews at the pad will move the payload into the Payload Ground Handling Mechanism (PGHM), and the rotating service structure (RSS) that protects the shuttle from the elements and provides access to its components will be rotated back into place. The payload is scheduled to be installed into the shuttle's cargo bay March 25. Endeavour and its six-member STS-134 crew are targeted to lift off April 19 at 7:48 p.m. EDT to deliver the payload to the International Space Station. This is Endeavour's final scheduled mission.

CAPE CANAVERAL, Fla. -- Space shuttle Atlantis, attached to its external fuel tank and solid rocket boosters atop a mobile launcher platform, makes its final debut outside the Vehicle Assembly Building. "Rollout," as it's called, to Launch Pad 39A at NASA's Kennedy Space Center in Florida began at 8:42 p.m. EDT. It will take the crawler-transporter about six hours to carry the shuttle stack to its seaside launch pad. The milestone move paves the way for the launch of the STS-135 mission to the International Space Station, targeted for July 8. 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.

CAPE CANAVERAL, Fla. -- Xenon lights illuminate space shuttle Atlantis' unfurled drag chute as the vehicle rolls to a stop on the Shuttle Landing Facility's Runway 15 at NASA's Kennedy Space Center in Florida for the final. Securing the space shuttle fleet's place in history, Atlantis marked the 26th nighttime landing of NASA's Space Shuttle Program and the 78th landing at Kennedy. Main gear touchdown was at 5:57:00 a.m. EDT, followed by nose gear touchdown at 5:57:20 a.m., and wheelstop at 5:57:54 a.m. On board are STS-135 Commander Chris Ferguson, Pilot Doug Hurley, and Mission Specialists Sandra Magnus and Rex Walheim. On the 37th shuttle mission to the International Space Station, STS-135 delivered more than 9,400 pounds of spare parts, equipment and supplies in the Raffaello multi-purpose logistics module that will sustain station operations for the next year. STS-135 was the 33rd and final flight for Atlantis, which has spent 307 days in space, orbited Earth 4,848 times and traveled 125,935,769 miles.

CAPE CANAVERAL, Fla. -- The container that carries the Raffaello multi-purpose logistics module (MPLM), secured on its transportation vehicle, begins its journey from the Canister Rotation Facility to Launch Pad 39A at NASA's Kennedy Space Center in Florida. Once there, the canister will be lifted to the payload changeout room. The payload ground-handling mechanism then will be used to transfer Raffaello out of the canister into space shuttle Atlantis' payload bay. Next, the rotating service structure that protects the shuttle from the elements and provides access will be rotated back into place. Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim are targeted to lift off on Atlantis July 8, taking with them the MPLM packed with supplies, logistics and spare parts to the station.

CAPE CANAVERAL, Fla. -- A Hyster forklift moves NASA's Juno spacecraft into Astrotech's payload processing facility in Titusville, Fla. to begin final testing and preparations for launch. The solar-powered spacecraft will orbit Jupiter's poles 33 times to find out more about the gas giant's origins, structure, atmosphere and magnetosphere and investigate the existence of a solid planetary core. Juno is scheduled to launch aboard an Atlas V rocket from Cape Canaveral, Fla. Aug. 5. For more information visit, www.nasa.gov/juno. Photo credit: NASA/Jack Pfaller It will splash down into the Atlantic Ocean where the ship and its crew will recover it and tow it back through Port Canaveral for refurbishing for another launch. The STS-124 mission is the second of three flights launching components to complete the Japan Aerospace Exploration Agency's Kibo laboratory.

The structure provides weather protection and access to the shuttle while it awaits lift off on the pad. RSS "rollback," as it's called, began at 11:44 a.m. EDT on May 15 and was completed at 12:24 p.m. STS-134 will deliver the Alpha Magnetic Spectrometer-2 (AMS), Express Logistics Carrier-3, a high-pressure gas tank and additional spare parts for the Dextre robotic helper to the International Space Station. May 16 at 8:56 a.m. will be the second launch attempt for Endeavour. The first attempt on April 29 was scrubbed because of an issue associated with a faulty power distribution box called the aft load control assembly-2 (ALCA-2).

CAPE CANAVERAL, Fla. - Backdropped by a beautiful blue sky and the crystal-clear Atlantic Ocean, space shuttle Endeavour is revealed 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 lift off on the pad. RSS "rollback," as it's called, began at 11:44 a.m. EDT on May 15 and was completed at 12:24 p.m. STS-134 will deliver the Alpha Magnetic Spectrometer-2 (AMS), Express Logistics Carrier-3, a high-pressure gas tank and additional spare parts for the Dextre robotic helper to the International Space Station. May 16 at 8:56 a.m. will be the second launch attempt for Endeavour. The first attempt on April 29 was scrubbed because of an issue associated with a faulty power distribution box called the aft load control assembly-2 (ALCA-2).

The STS-135 mission also will fly a system to investigate the potential for robotically refueling existing satellites and return 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.

The work is expected to take about a week, which still would support Atlantis' targeted July 8 launch date. STS-135 Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandy Magnus and Rex Walheim are targeted to lift off on space shuttle Atlantis July 8, taking with them the MPLM packed with supplies, logistics and spare parts to the International Space Station.

CAPE CANAVERAL, Fla. -- The STS-135 crew members express their gratitude to the thousands of workers who have processed, launched and landed the space shuttles for more than three decades during an employee appreciation event. From left, are Mission Specialists Rex Walheim and Sandy Magnus, Commander Chris Ferguson, and Pilot Doug Hurley. Space shuttle Atlantis' final return from space at 5:57 a.m. EDT secured the space shuttle fleet's place in history and brought a close to the STS-135 mission and America's Space Shuttle Program. STS-135 delivered spare parts, equipment and supplies to the International Space Station. STS-135 was the 33rd and final flight for Atlantis, which has spent 307 days in space, orbited Earth 4,848 times and traveled 125,935,769 miles.
