      Test Stand Construction Collection: Stennis Space Center Collection Title: Test Stand Construction Creator: NASA/Stennis Space Center Description: Construction crews install steel reinforcing rods at the base of what became the A-2 test stand. The excavation for the stand went down 50 feet with steel H-beams driven 100 feet deeper to form a foundation for the huge piers of the test stand.

            STS-131 Discovery Launch Collection: STS-131 Gallery Title: STS-131 Discovery Launch Creator: NASA/Bill Ingalls Description: Contrails are seen as workers leave the Launch Control Center after the launch of the space shuttle Discovery and the start of the STS-131 mission at NASA Kennedy Space Center in Cape Canaveral, Fla. on Monday April 5, 2010. Discovery is carrying a multi-purpose logistics module filled with science racks for the laboratories aboard the station. The mission has three planned spacewalks, with work to include replacing an ammonia tank assembly, retrieving a Japanese experiment from the station's exterior, and switching out a rate gyro assembly on the station's truss structure.

              Magnetic Launch Assist System Demonstration Test Collection: NASA Marshall Space Flight Center Collection Name of Image: Magnetic Launch Assist System Demonstration Test Full Description: Engineers at the Marshall Space Flight Center (MSFC) have been testing Magnetic Launch Assist Systems, formerly known as Magnetic Levitation (MagLev) technologies. To launch spacecraft into orbit, a Magnetic Launch Assist system would use magnetic fields to levitate and accelerate a vehicle along a track at a very high speed. Similar to high-speed trains and roller coasters that use high-strength magnets to lift and propel a vehicle a couple of inches above a guideway, the launch-assist system would electromagnetically drive a space vehicle along the track. A full-scale, operational track would be about 1.5-miles long and capable of accelerating a vehicle to 600 mph in 9.5 seconds. This photograph shows a subscale model of an airplane running on the experimental track at MSFC during the demonstration test. This track is an advanced linear induction motor. Induction motors are common in fans, power drills, and sewing machines. Instead of spinning in a circular motion to turn a shaft or gears, a linear induction motor produces thrust in a straight line. Mounted on concrete pedestals, the track is 100-feet long, about 2-feet wide, and about 1.5- feet high. The major advantages of launch assist for NASA launch vehicles is that it reduces the weight of the take-off, the landing gear, the wing size, and less propellant resulting in significant cost savings. The US Navy and the British MOD (Ministry of Defense) are planning to use magnetic launch assist for their next generation aircraft carriers as the aircraft launch system. The US Army is considering using this technology for launching target drones for anti-aircraft training. Date of Image: 2001-03-01

                STS-112 Shuttle Mission Collection: NASA Human Spaceflight Collection General Description: STS-112 Shuttle Mission Imagery Description: KSC-02PD-1455 (10/07/2002) --- KENNEDY SPACE CENTER, FLA. - Looking like a star balanced on a stem of smoke, Space Shuttle Atlantis shoots through the clear blue sky after launch on mission STS-112, the 15th assembly flight to the International Space Station. Liftoff from Launch Pad 39B occurred at 3:46 p.m. EDT. Atlantis carries the S1 Integrated Truss Structure and the Crew and Equipment Translation Aid (CETA) Cart A. The CETA is the first of two human-powered carts that will ride along the ISS railway, providing mobile work platforms for future spacewalking astronauts. On the 11-day mission, three spacewalks are planned to attach the S1 truss.

                  Return to Flight Collection: NASA Kennedy Center Media Archive Collection Description: KENNEDY SPACE CENTER, FLA. - Spectators at the NASA News Center at Kennedy Space Center get a birds-eye-view of Space Shuttle Discovery as it roars through a stray cloud after liftoff at 10:39 a.m. EDT from NASA Kennedy Space Center's Launch Pad 39B on the historic Return to Flight mission STS-114. It is the 114th Space Shuttle flight and the 31st for Discovery. The 12-day mission is expected to end with touchdown at the Shuttle Landing Facility on Aug. 7. On this 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.
