The Space Launch Initiative (SLI) was a NASA and U.S. Department of Defense joint research and technology project to determine the requirements to meet all the nation’s hypersonics, space launch and space technology needs. The program began with the award of reusable launch vehicle study contracts in 2000.
The primary goal of this research was to increase safety and reliability and to reduce overall costs associated with building, flying and maintaining the nation’s next generation of space launch vehicles. NASA anticipated that these advances would revitalize the nation’s space transportation capabilities, and dramatically improve NASA’s ability to conduct science and exploration missions in space.|This program was ended with the cancellation of the X-33 and X-34 and the conclusion of the X-43 programs. NASA changed its focus to Constellation Program.
The Space Launch Initiative Propulsion Office -- managed by NASA’s Marshall Space Flight Center in Huntsville, Ala., -- sought to advance technologies and explore new avenues of space propulsion to develop safer, more reliable and affordable propulsion solutions. Four main engine candidates for a second generation reusable launch vehicle emerged, including two hydrogen-fueled (COBRA, RS-83, TR-106) and two kerosene-fueled (RS-84, TR-107) staged combustion engines.
California Poly Pomona's Professor Steven Dobbs was the Lead Systems Engineer on the project, making significant use of the program as an example for failed systems engineering.

Famous quotes containing the words space, launch and/or initiative:
“What a phenomenon it has been—science fiction, space fiction—exploding out of nowhere, unexpectedly of course, as always happens when the human mind is being forced to expand; this time starwards, galaxy-wise, and who knows where next.”
—Doris Lessing (b. 1919)
“Now launch the small ship, now as the body dies
and life departs, launch out, the fragile soul
in the fragile ship of courage, the ark of faith
with its store of food and little cooking pans
and change of clothes,”
—D.H. (David Herbert)
“I am firmly opposed to the government entering into any business the major purpose of which is competition with our citizens ... for the Federal Government deliberately to go out to build up and expand ... a power and manufacturing business is to break down the initiative and enterprise of the American people; it is the destruction of equality of opportunity amongst our people, it is the negation of the ideals upon which our civilization has been based.”
—Herbert Hoover (1874–1964)
