The X-33 Program will demonstrate the key design and operational aspects of a Single Stage to Orbit (SSTO) Reusable Launch Vehicle (RLV) rocket system so as to reduce the risk to the private sector in developing such a commercially viable system. The X-33 program will implement the National Space Transportation Policy, specifically Section III, paragraph 2(a): "The objective of NASA's technology development and demonstration effort is to support government and private sector decisions by the end of this decade on development of an operational next-generation reusable launch system."

As of March 1, 2001, the x-33 project as well as the x-34 project were discontinued by NASA. See the following

On August 28, 1996, NASA awarded to Orbital Sciences Corporation (OSC) a contract for the design, development, and testing of the X-34 technology testbed demonstrator vehicle. The intent of the X-34 program is to demonstrate "key technologies" integratable to the Reusable Launch Vehicle program. This vehicle is the bridge between the Clipper Graham (DC-XA) and the X-33. This contract will be managed by the Marshall Space Flight Center (MSFC).

As of March 1, 2001, the x-33 project as well as the x-34 project were discontinued by NASA. See the following

The NASA Advanced Space Transportation Program (ASTP) is focused on enabling the threshold characteristic of 100 times reduction in cost and improved reliability and safety. The ASTP is structured in four major elements (or projects) which correlated with the three technology needs proposed by the 1986 Report of the National Commission on Space. The commission stated the needs of the first technology area in two parts that would result in four technology need areas. These are (1) “significantly lowering the cost to achieve low-Earth orbit” by (a) “lowering the cost of unpiloted launches” and (b) “reusable vehicles that are reliable and robust,” (2) “safe, reliable, low-cost transportation in space,” and (3) “increased propulsion performance to allow higher velocity changes in space to reach distant locations.
