Science and Technology, Reusable Launch Vehicle

NASA's Reusable Launch Vehicle (RLV) program has dual objectives: to demonstrate technologies leading to a new generation of space boosters capable of delivering payloads at significantly lower cost,

and to provide a technology base for development of advanced commercial launch systems that will make U.S. aerospace manufacturers more competitive in the global market. x33-3_072.jpg (72 dpi) - 30027 Bytes x33-3_300.jpg (300 dpi) - 187346 Bytes

Launched in 1994, the RLV program moved ahead on two fronts in 1996 with a restructuring of the X-34 air-launched small booster project and selection of a contractor for development of the larger X-33 technology demonstrator.

In development for first flight in 1999 is the NASA/Lockheed Martin X-33 Advanced Technology Demonstrator, intended as the prototype of a 21st century low-cost-to-orbit reusable launch vehicle.

Ames Research Center will contribute thermal protection technology and Langley Research Center will handle computational fluid dynamics and aerodynamic testing.

Industry firms participating include AlliedSignal Aerospace, Torrance, California, which is developing advanced avionics and hydraulic power systems; Oceaneering Space Systems, Houston, Texas (re-entry thermal control); and Charles Stark Draper Laboratory, Cambridge, Massachusetts (navigation and guidance technology).

Description: Albert Einstein during a lecture in Vienna in 1921. Date: 1921. Author: Ferdinand Schmutzer (1870–1928) Permission: Public Domain.

This image (or other media file) is in the public domain because it's copyright has expired. This applies to the United States, where Works published prior to 1978 were copyright protected for a maximum of 75 years. See Circular 1 "COPYRIGHT BASICS" PDF. Works published before 1923, in this case 1921, are now in the public domain.

This image is also in the public domain in countries that figure copyright from the date of death of the artist (post mortem auctoris), in this case, Ferdinand Schmutzer (1870–1928), and that most commonly runs for a period of 50 to 70 years from the last day of that year.
