As such, spare parts may be swapped onto a craft before launch, or completed spare spacecraft may be launched if the flight model is lost. NASA has two basic types of spares, development spares and operational spares. NASA makes a determination about which parts need spares based on whether parts are custom built, and the lead-time for procurement.
The left side latch on the SAFER unit became unlatched during an EVA by astronaut Piers Sellers on STS-121 while testing shuttle repair techniques. [8] [9] The latch had been inadvertently bumped and moved to the unlatch position. As a precaution, Mike Fossum tethered it to him and the spacewalk continued. [10]
The concept for the vehicle was officially announced in a speech given by George W. Bush at NASA Headquarters on January 14, 2004. [1] The Draft Statement of Work for the CEV was issued by NASA on December 9, 2004, and slightly more than one month later, on January 21, 2005, NASA issued a Draft Request For Proposal (RFP).
The Shuttle-C was a study by NASA to turn the Space Shuttle launch stack into a dedicated uncrewed cargo launcher. The Space Shuttle external tank and Space Shuttle Solid Rocket Boosters (SRBs) would be combined with a cargo module in place of the shuttle orbiter including the RS-25 engines. Various Shuttle-C concepts were investigated between ...
The RS-25 engine consists of pumps, valves, and other components working in concert to produce thrust. Fuel (liquid hydrogen) and oxidizer (liquid oxygen) from the Space Shuttle's external tank entered the orbiter at the umbilical disconnect valves and from there flowed through the orbiter's main propulsion system (MPS) feed lines; whereas in the Space Launch System (SLS), fuel and oxidizer ...
The Shuttle Carrier Aircraft (SCA) are two extensively modified Boeing 747 airliners that NASA used to transport Space Shuttle orbiters. One (N905NA) is a 747-100 model, while the other (N911NA) is a short-range 747-100SR.
The majority of the NASA factory's history was focused on construction and production of NASA's Space Shuttle external tank (ET). Beginning with the rollout of ET-1 on June 29, 1979, which flew on STS-1 , 136 tanks were produced throughout the Space Shuttle program, ending with the flight-ready tank ET-122, which flew on STS-134 , rolled out on ...
Nuclear Ferry and Shuttle Orbiter docked to an Orbital Propellant Depot. The Space Transportation System (STS), also known internally to NASA as the Integrated Program Plan (IPP), [1] was a proposed system of reusable crewed space vehicles envisioned in 1969 to support extended operations beyond the Apollo program (NASA appropriated the name for its Space Shuttle Program, the only component of ...
