NASA launch vehicles - The next twenty years

Abstract

Future space activities call for robust, reliable, cost-effective access to space, together with greater launch capacity. Attention is presently given to prospective developments in the field of cargo launch vehicle design, whose near-term goal for NASA is the Shuttle-C Space Shuttle-development unmanned vehicle. In the longer term, the Advanced Launch System will be developed jointly by NASA and the DOD for LEO placement of payloads of as much as 200,000 lb. NASA is studying ways of developing the current manned Space Shuttle Orbiter through incorporation of emerging technologies; eventually, a 'Shuttle-II' vehicle will be developed.
