On July 14, 1999 NASA and Boeing completed negotiations on a $173 million cooperative agreement to develop an experimental space plane called the X-37, which will serve as a test bed for new reusable launch vehicle technologies. The reusable vehicle (formerly known as the Future-X Pathfinder) can be ferried into orbit by the Space Shuttle or launched by an expendable rocket. It will be unpiloted, autonomously operated and capable of speeds up to Mach 25 while demonstrating aircraft-like operations. The design, based on the Boeing X-40A space maneuver vehicle, will incorporate advanced technologies and processes from throughout the company.
