Since the 1980s NASA has struggled to develop a new launch system to provide safe routine and less expensive access to space. Over the years numerous concepts have been studied but few have made it beyond concept definition and none have flown in space. In March 2001 NASA canceled the X-33 single-stage-to-orbit program and the X-34 technology demonstrator after spending $1.4 billion. NASA concluded that the technical barriers of the X-33 were too great and that the benefits of the X-34 did not justify the cost. Last year NASA canceled the X-38 a prototype of a Crew Return Vehicle CRV because it was believed that a multi-purpose vehicle would be a better use of its resources. NASA is continuing to move forward with the X-37 flight demonstration but its value and relevance as a technology demonstrator is questionable because the on-orbit demonstration would not occur until after NASA made its decision for full-scale development. NASA submitted a budget amendment to its FY 2003 request to restructure and refocus the ISTP. The budget amendment proposed to extend the life of the Space Shuttle by creating a Service Life Extension Program SLEP to establish a program to develop an OSP for crew rescue and crew transportation to Space Station and to establish a technology program called the Next Generation Launch Technology NGLT program. Because the budget amendment was submitted late in the 107th Congress the Omnibus appropriations report specifically stated that the ''funding level is not endorsed or denied'' but wanted to examine the details of the proposal especially cost. The Omnibus bill did provide funding for the OSP at the requested level of $296 million for FY 2003. Other than minor changes NASA's FY 2004 budget request reflects the program proposed in the budget amendment. This is the first hearing held by any committee on NASA's ISTP and OSP plans. U. S.
