The hydraulic pressure generated was also used to control all of the orbiter's flight control surfaces (the elevons, rudder, speed brake, etc.), to deploy the landing gear of the orbiter, and to retract the umbilical hose connection doors located near the rear landing gear, which supplied the orbiter's SSMEs with liquid hydrogen and oxygen from ...
A final flare maneuver reduced the orbiter vehicle's descent rate to 0.9 m/s (3 ft/s), with touchdown occurring at 100–150 m/s (195–295 kn), depending on the weight of the orbiter vehicle. After the landing gear touched down, the crew deployed a drag chute out of the vertical stabilizer, and began wheel braking when the orbiter was ...
Atlantis' main gear touched down at 06:21:30 EDT on Runway 33 at the Space Shuttle Landing Facility at Kennedy Space Center, with the nose gear following 6 seconds later at 06:21:36 EDT, and, 8,000,000 kilometres (5,000,000 mi) after launch, the Orbiter's wheels came to a stop at 06:22:16 EDT, bringing mission STS-115 to an end.
Images taken by the Lunar Reconnaissance Orbiter mission beginning in July 2009 show the six Apollo Lunar Module descent stages, Apollo Lunar Surface Experiments Package (ALSEP) science experiments, astronaut footpaths, and lunar rover tire tracks. These images are the most effective proof to date to rebut the "landing hoax" theories.
NASA did not expect this to hurt the mission because it did not hit the orbiter, and because the vehicle was traveling relatively slowly at the time. A small fragment of thermal tile, estimated to be around 1.5 inches (38 mm) in size, was ejected from an edge tile of the front landing gear door at some point before SRB separation. A small white ...
Other safety changes included a new escape system for use when the orbiter was in controlled flight, improved landing gear tires and brakes, and the reintroduction of pressure suits for Shuttle astronauts (these had been discontinued after STS-4; astronauts wore only coveralls and oxygen helmets from that point on until the Challenger accident).
After a day on the lunar surface the LK's engine would fire again, using its landing leg structure as a launch pad. To save weight, the engine used for landing would also blast the LK back to lunar orbit for an automated docking with the LOK, using the Soyuz Kontakt docking system. The cosmonaut would then spacewalk back to the LOK carrying the ...
Space Shuttle Enterprise (Orbiter Vehicle Designation: OV-101) was the first orbiter of the Space Shuttle system. Rolled out on September 17, 1976, it was built for NASA as part of the Space Shuttle program to perform atmospheric test flights after being launched from a modified Boeing 747. [1]
