Bulletin of the Atomic Scientists, 1973
“The most serious problems with the space shuttle can be summarized as follows: its questionable role in competing national priorities and internal NASA priorities; the lack of a clear definition of NASA's goals for shuttle use; the uncertainties in the recurring cost of the use and possible reuse of solid-fueled boosters; the questionable need for ...

Bailout from the Space Shuttle
3rd Flight Testing Conference and Technical Display, 1986Studies to investigate the bailout characteristics from the Space Shuttle Orbiter at low-subsonic speeds have been made in the Langley 12-foot Low-Speed Tunnel and the Langley 4- by 7Meter Tunnel with 0.03-scale models. The effect of crew-model exit velocity, body posture, and body weight were studied with egress from the Orbiter main side hatch and ...

14th Joint Propulsion Conference, 1978
Two Space Shuttle solid propellant rocket motor (SRM) nozzles have been tested, both successfully. This paper summarizes the results of these tests. The SRM nozzle was designed and fabricated at the Wasatch Division of Thiokol Corporation. It is over 13 ft. long, has a 54.43 in. initial throat diameter, and weighs over 11 tons.

Shuttle of approval [space launch]
Engineering & Technology, 2007The author examines the end-user effect on NASA's pioneering technologies. Conducting the myriad of space launch preparations requires innovative technologies. Although the mission of the Applied Physics Laboratory at NASA's Kennedy Space Center is to deliver gadgets to support these launch missions and operations, it is the verdict of the end-users (i.

Representative Space Shuttle missions and their impact on shuttle design
Joint Space Mission Planning and Execution Meeting, 1973Four representative Space Shuttle missions for the 1980's are described: mission 1, a third stage deployment and retrieval mission; mission 2, a combination orbiting element revisit and sortie mission; mission 3, a rapid payload retrieval and return mission; and mission 4, a 30-day earth observation sortie mission. The first three missions are proposed

Space shuttle operations experience
Acta Astronautica, 1988Abstract In twenty-five Space Shuttle flights, NASA has learned valuable lessons which will improve future operations and designs of space launch vehicles. The major lessons learned from Shuttle operations are addressed. Flight operations experience has demonstrated the reusability of the orbiter, the solid rocket boosters, and main engines. However,

A reappraisal of the Space Shuttle programme
Space Policy, 1993Abstract The conventional wisdom holds that the Space Shuttle programme has been a ‘policy failure’ because NASA compromised its original concept in the face of weak political commitment and inadequate funding. However, a detailed reappraisal of the history shows that this reasoning is ambiguous, counterfactual and contrary to experience ...

Space Shuttle orbiter and subsystems
Joint Space Mission Planning and Execution Meeting, 1973Considerable progress has been made in designing the Space Shuttle orbiter and defining its subsystems since the development contract was awarded by NASA to Rockwell International in August 1972. This paper describes the orbiter's current design characteristics and its major assemblies.
