Pictured here is an artist's depiction of Rockwell's Vertical Landing Single-Stage-to-Orbit (SSTO) Reusable Launch Vehicle (RLV) deploying a satellite concept. The development of the RLV is essential in the cost reduction of future space travel.

Pictured here is an artist's depiction of Lockheed Martin's Lifting Body Single-Stage-to-Orbit (SSTO) Reusable Launch Vehicle (RLV) concept servicing the International Space Station. The development of the RLV is essential in the cost reduction of future space travel.

Pictured here is an artist's depiction of the McDornel Douglas' wing body Single-Stage-to-Orbit (SSTO) Reusable Launch Vehicle (RLV) servicing the Hubble Space Telescope (HST) concept. The development of the RLV is essential in the cost reduction of future space travel.

Pictured is a component of the Rocket Based Combined Cycle (RBCC) engine. This engine was designed to ultimately serve as the near term basis for Two Stage to Orbit (TSTO) air breathing propulsion systems and ultimately a Single Stage to Orbit (SSTO) air breathing propulsion system.

Artist John Frassanito's concept of three Single-Stage-to-Orbit (SSTO) Reusable Launch Vehicles (RLV's). Depicted from the left are: The Lockheed-Martin lifting body configuration that uses an integrated linear aerospike main engine; the McDornell Douglas vertical landing configuration; and the Rockwell wing body configuration that uses liquid oxygen and hydrogen bell engines.

Pictured is an artist's concept of the Rocket Based Combined Cycle (RBCC) launch. The RBCC's overall objective is to provide a technology test bed to investigate critical technologies associated with opperational usage of these engines. The program will focus on near term technologies that can be leveraged to ultimately serve as the near term basis for Two Stage to Orbit (TSTO) air breathing propulsions systems and ultimately a Single Stage To Orbit (SSTO) air breathing propulsion system.
