Space Shuttle design process. Before the Apollo 11 Moon landing in 1969, NASA began studies of Space Shuttle designs as early as October 1968. The early studies were denoted "Phase A", and in June 1970, "Phase B", which were more detailed and specific. The primary intended use of the Phase A Space Shuttle was supporting the future space station ...
Studied Space Shuttle designs. Artist's concept of 35-foot-diameter (10.6 m) Hammerhead configuration at launch. During the lifetime of the Space Shuttle, Rockwell International and many other organizations studied various Space Shuttle designs. These involved different ways of increasing cargo and crew capacity, as well as investigating ...
During the design of the Space Shuttle, the Phase B proposals were not as cheap as the initial Phase A estimates indicated; Space Shuttle program manager Robert Thompson acknowledged that reducing cost-per-pound was not the primary objective of the further design phases, as other technical requirements could not be met with the reduced costs. [21]:
The partial reusability of the Space Shuttle was one of the primary design requirements during its initial development. [65]: 164 The technical decisions that dictated the orbiter's return and re-use reduced the per-launch payload capabilities. The original intention was to compensate for this lower payload by lowering the per-launch costs and ...
The Space Shuttle orbiter is the spaceplane component of the Space Shuttle, a partially reusable orbital spacecraft system that was part of the discontinued Space Shuttle program. Operated from 1981 to 2011 by NASA, [ 1 ] the U.S. space agency, this vehicle could carry astronauts and payloads into low Earth orbit, perform in-space operations ...
The Space Shuttle Orbiter mockup was constructed by North American Rockwell in 1972. It was shown to NASA and Congress to win approval for the Space Shuttle program. The mockup is approximately the same size and shape as an actual Orbiter. It was also used to design cable harnesses for production shuttle Orbiters and to test-fit flight hardware.
NASA started the Space Shuttle design process in 1968, with the vision of creating a fully reusable spaceplane using a crewed fly-back booster. This concept proved expensive and complex, therefore the design was scaled back to reusable solid rocket boosters and an expendable external tank.
The Space Shuttle Solid Rocket Booster (SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. [1] A pair of these provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent.
