The Boeing Orbital Space Plane (OSP) will seat 4 to 6 crew and will serve as a crew rescue vehicle and crew transfer vehicle for the International Space Station. Boeing is pursuing a variety of configuration alternatives for OSP including derivatives of the X-37 and Apollo capsule. The Boeing Company has nearly 50 years of experience producing human-rated spacecraft for NASA and will put that expertise to good use in designing the OSP for NASA.
