CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, space shuttle Atlantis' main engines and solid rocket boosters ignite on Launch Pad 39A leaving behind a billow of steam as it lifts off on its STS-135 mission to the International Space Station. Atlantis with its crew of four; Commander Chris Ferguson, Pilot Doug Hurley, Mission Specialists Sandy Magnus and Rex Walheim, lifted off at 11:29 a.m. EDT on July 8, 2011 to deliver the Raffaello multi-purpose logistics module packed with supplies and spare parts for 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 is 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.

KENNEDY SPACE CENTER, FLA. -- Space Shuttle Atlantis rockets into the blue sky above Launch Pad 39A after liftoff. Beneath Atlantis' main engines are blue cones of light, known as shock or mach diamonds. They are a formation of shock waves in the exhaust plume of an aerospace propulsion system. Liftoff of Atlantis on mission STS-117 to the International Space Station was on time at 7:38:04 p.m. EDT. The shuttle is delivering a new segment to the starboard side of the International Space Station's backbone, known as the truss. Three spacewalks are planned to install the S3/S4 truss segment, deploy a set of solar arrays and prepare them for operation. STS-117 is the 118th space shuttle flight, the 21st flight to the station, the 28th flight for Atlantis and the first of four flights planned for 2007.

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. -- 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. 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.

CAPE CANAVERAL, Fla. -- At the Merritt Island Launch Annex (MILA) Spaceflight Tracking and Data Network Station at NASA's Kennedy Space Center in Florida, the Patrick Air Force Base Color Guard presents the U.S. flag which flew over the station to David Carter, Near Earth Network project manager at Goddard Space Flight Center, during a closing ceremony recognizing the station's 45 years of service. The flag will be displayed in a Network Integration Center display cabinet at Goddard. The station was originally established by NASA's Goddard Space Flight Center as one of 17 Space Flight Tracking and Data Network stations around the world. Commissioned for the Apollo Program, the first launch it supported was the Apollo/Saturn 203 test flight from Launch Complex 37 on July 5, 1966. It also provided orbital support for low earth-orbiting scientific satellites. In recent history, the station has been used almost exclusively for space shuttle launch and landing support. Following the final launch and landing of the Space Shuttle Program in July 2011, the MILA station is officially decommissioned.

CAPE CANAVERAL, Fla. -- Liberty Star, one of NASA's solid rocket booster retrieval ships, tows the right spent booster from space shuttle Atlantis' final launch, as it is taken to Port Canaveral in Florida. The shuttle's two solid rocket booster casings and associated flight hardware are recovered in the Atlantic Ocean after every launch by Freedom Star and Liberty Star. The boosters impact the Atlantic about seven minutes after liftoff and the retrieval ships are stationed about 10 miles from the impact area at the time of splashdown. After the spent segments are processed, they will be transported to Utah, where they will be deserviced and stored, if needed. Atlantis began its final flight at 11:29 a.m. EDT on July 8 to deliver the Raffaello multi-purpose logistics module packed with supplies and spare parts for the International Space Station. Atlantis also delivers the Robotic Refueling Mission experiment that will investigate the potential for robotically refueling existing satellites in orbit to the station.

CAPE CANAVERAL, Fla. -- At the Merritt Island Launch Annex (MILA) Spaceflight Tracking and Data Network Station at NASA's Kennedy Space Center in Florida, the Patrick Air Force Base Color Guard folds the U.S. flag for the last time at a closing ceremony recognizing the station's 45 years of service. The station was originally established by NASA's Goddard Space Flight Center as one of 17 Space Flight Tracking and Data Network stations around the world. Commissioned for the Apollo Program, the first launch it supported was the Apollo/Saturn 203 test flight from Launch Complex 37 on July 5, 1966. It also provided orbital support for low earth-orbiting scientific satellites. In recent history, the station has been used almost exclusively for space shuttle launch and landing support. Following the final launch and landing of the Space Shuttle Program in July 2011, the MILA station is officially decommissioned.

KENNEDY SPACE CENTER, FLA. -- Noted physicist Stephen Hawking arrives at the Kennedy Space Center Shuttle Landing Facility for his first zero-gravity flight. The flight will be aboard a modified Boeing 727 aircraft owned by Zero Gravity Corp., a commercial company licensed to provide the public with weightless flight experiences. Hawking developed amyotrophic lateral sclerosis disease in the 1960s, a type of motor neuron disease which would cost him the loss of almost all neuromuscular control. At the celebration of his 65th birthday on January 8 this year, Hawking announced his plans for a zero-gravity flight to prepare for a sub-orbital space flight in 2009 on Virgin Galactic's space service.

CAPE CANAVERAL, Fla. -- During a tanking test on June 15 at Launch Pad 39A at NASA's Kennedy Space Center in Florida, there was an apparent liquid hydrogen leak in the main fuel valve in Atlantis' space shuttle main engine No. 3. Technicians now are replacing the suspect valve and a leak check of the valve and associated systems will be conducted. 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. 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.

CAPE CANAVERAL, Fla. -- Shuttle Atlantis' three main engines take center stage in this image as Atlantis is being moved to the Vehicle Assembly Building (VAB) from Orbiter Processing Faciity-1 at NASA's Kennedy Space Center in Florida. The move called "rollover" is a major milestone in processing for the STS-135 mission to the International Space Station. Inside the VAB, the shuttle will be attached to its external fuel tank and solid rocket boosters. Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim are targeted to launch in early July, taking with them the Raffaello multipurpose logistics module packed with supplies, logistics and spare parts. The STS-135 mission also will fly a system to investigate the potential for robotically refueling existing spacecraft 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.
