STS031-S-131 (29 April 1990) --- Low angle view of the Space Shuttle Discovery as it approaches for landing on a concrete runway at Edwards Air Force Base to complete a highly successful five-day mission. It was a long awaited Earth orbital flight during which the Hubble Space Telescope (HST) was sent toward its 15-year mission. Discovery's wheels came to a complete stop at 6:51:00 a.m. (PDT), April 29, 1990. The landing gear was deployed just moments after this frame was exposed. Inside the spacecraft for STS-31 were astronauts Loren J. Shriver, Charles F. Bolden, Bruce McCandless II, Kathryn D. Sullivan and Steven A. Hawley.

KENNEDY SPACE CENTER, FLA. -- In high bay No. 1 of the Vehicle Assembly Building, Space Shuttle Atlantis awaits its return to Launch Pad 39A. In late February, Atlantis' external tank received hail damage during a severe thunderstorm that passed through the Kennedy Space Center Launch Complex 39 area. The hail caused visible divots in the giant tank's foam insulation, as well as minor surface damage to about 26 heat shield tiles on the shuttle's left wing. The launch of Space Shuttle Atlantis on mission STS-117 is now targeted for June 8. A flight readiness review will be held on May 30 and 31. Photo credit: NASA/Troy Cryder

CAPE CANAVERAL, Fla. - STS-130 Mission Specialist Kathryn Hire, left, and Pilot Terry Virts inspect the thermal protection system tiles under space shuttle Endeavour following its successful landing on Runway 15 at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. After 14 days in space, Endeavour's 5.7-million-mile STS-130 mission was completed on orbit 217. Main gear touchdown was at 10:20:31 p.m. EST followed by nose gear touchdown at 10:20:39 p.m. and wheels stop at 10:22:10 p.m. It was the 23rd night landing in shuttle history and the 17th at Kennedy. During Endeavour's STS-130 mission, astronauts installed the Tranquility node, a module that provides additional room for crew members and many of the station's life support and environmental control systems. Attached to Tranquility is a cupola with seven windows that provide a panoramic view of Earth, celestial objects and visiting spacecraft. The module was built in Turin, Italy, by Thales Alenia Space for the European Space Agency. The orbiting laboratory is approximately 90 percent complete now in terms of mass. STS-130 was the 24th flight for Endeavour, the 32nd shuttle mission devoted to ISS assembly and maintenance, and the 130th shuttle mission to date.

KENNEDY SPACE CENTER, FLA. -- Viewed across an arm of the Banana River, Space Shuttle Atlantis sits on Launch Pad 39A. At right of the pad is the 300,000-gallon water tower that provides the water for sound suppression during liftoff. Atlantis rolled out to the pad for the second time before dawn. First motion out of the Vehicle Assembly Building was at 5:02 a.m. EDT. In late February, while Atlantis was on the launch pad, Atlantis' external tank received hail damage during a severe thunderstorm that passed through the Kennedy Space Center Launch Complex 39 area. The hail caused visible divots in the giant tank's foam insulation, as well as minor surface damage to about 26 heat shield tiles on the shuttle's left wing. The shuttle was returned to the VAB for repairs. The launch of Space Shuttle Atlantis on mission STS-117 is now targeted for June 8. A flight readiness review will be held on May 30 and 31.

KENNEDY SPACE CENTER, FLA. -- Space Shuttle Atlantis, mounted on a mobile launch platform, finally rests on the hard stand of Launch Pad 39A after an early morning rollout. This is the second rollout for the shuttle. Seen on either side of the main engine exhaust hole on the launcher platform are the tail service masts. Their function is to provide umbilical connections for liquid oxygen and liquid hydrogen lines to fuel the external tank from storage tanks adjacent to the launch pad. Other umbilical lines carry helium and nitrogen, as well as ground electrical power and connections for vehicle data and communications.

KENNEDY SPACE CENTER, FLA. - Lights on Launch Pad 39B put Space Shuttle Discovery in the spotlight after the rollback of the Rotating Service Structure (at left). The Space Shuttle sits on the Mobile Launcher Platform (MLP), which is 25 ft. high, 160 ft. long and 135 ft. wide. An MLP weighs 8,230,000 pounds. At the launch pad, with a fueled Shuttle on the 6-inch-thick decks, it weighs approximately12,700,000 pounds. There are three exhaust openings in the main deck of an MLP. Two are for the exhaust of the SRBs at launch and the third, a center opening, is for the exhaust from the main engines. SRB exhaust holes are 42 ft. long and 20 ft. wide. The main engine hole is 34 ft. long and 31 ft. wide. Discovery is scheduled to launch on the historic Return to Flight mission STS-114 at 3:51 p.m. July 13 with a crew of seven. On the mission to the International Space Station the crew will perform inspections on orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission Specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay. During two additional spacewalks, the crew will install the External Stowage Platform-2, equipped with spare part assemblies, and a replacement Control Moment Gyroscope contained in the Lightweight Multi-Purpose Experiment Support Structure.

CAPE CANAVERAL, Fla. - From left, STS-130 Commander George Zamka, Mission Specialist Kathryn Hire and Pilot Terry Virts inspect the thermal protection system tiles under space shuttle Endeavour following its successful landing on Runway 15 at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. After 14 days in space, Endeavour's 5.7-million-mile STS-130 mission was completed on orbit 217. Main gear touchdown was at 10:20:31 p.m. EST followed by nose gear touchdown at 10:20:39 p.m. and wheels stop at 10:22:10 p.m. It was the 23rd night landing in shuttle history and the 17th at Kennedy. During Endeavour's STS-130 mission, astronauts installed the Tranquility node, a module that provides additional room for crew members and many of the station's life support and environmental control systems. Attached to Tranquility is a cupola with seven windows that provide a panoramic view of Earth, celestial objects and visiting spacecraft. The module was built in Turin, Italy, by Thales Alenia Space for the European Space Agency. The orbiting laboratory is approximately 90 percent complete now in terms of mass. STS-130 was the 24th flight for Endeavour, the 32nd shuttle mission devoted to ISS assembly and maintenance, and the 130th shuttle mission to date.

KENNEDY SPACE CENTER, FLA. -- Space Shuttle Atlantis, mounted on a mobile launch platform, finally rests on the hard stand of Launch Pad 39A, straddling the flame trench. This is the second rollout for the shuttle. The flame trench transecting the pad's mound at ground level is 490 feet long, 58 feet wide and 40 feet high. It is made of concrete and refractory brick. Pad structures are insulated from the intense heat of launch by the flame deflector system, which protects the flame trench floor and the pad surface along the top of the flame trench. On the left of the shuttle are the fixed service structure and rotating service structure in open position. When closed, the rotating structure provides protected access to the orbiter for changeout and servicing of payloads at the pad. It is supported by a rotating bridge that pivots about a vertical axis on the west side of the pad's flame trench. The white area in the center is the Payload Changeout Room, an enclosed, environmentally controlled portion of the rotating service structure that supports payload delivery at the launch pad and subsequent vertical installation in the orbiter payload bay. First motion out of the Vehicle Assembly Building was at 5:02 a.m. EDT. In late February, while Atlantis was on the launch pad, Atlantis' external tank received hail damage during a severe thunderstorm that passed through the Kennedy Space Center Launch Complex 39 area. The hail caused visible divots in the giant tank's foam insulation, as well as minor surface damage to about 26 heat shield tiles on the shuttle's left wing.
