NASA COMPLETES ORBITAL SPACE PLANE DESIGN REVIEW 

NASA's Orbital Space Plane (OSP) program is one step closer to becoming
the
nation's next space vehicle with the successful completion of its
Systems
Requirements Review. The review evaluated the vehicle's concept design
for
providing crew rescue and transfer for the International Space Station.

The NASA-led review evaluated contractor designs based on the primary
design
criteria, or Level 1 requirements, set by the agency in February. The
contractor teams designing the OSP, The Boeing Company, Seal Beach,
Calif.;
Lockheed Martin, Denver; and a team including Orbital Sciences Corp.,
Dulles, Va., and Northrop Grumman, El Segundo, Calif., have been working
to
develop system specifications, including systems analysis, trade
studies,
and concept feasibility in preparation for the review.

The System Requirements Review includes analysis of requirements and
supporting technical documentation to ensure the system is safe,
reliable,
maintainable and affordable. It is one in a series of reviews that
occurs
before the Orbital Space Plane system is built. 

In addition, the review set Level 2 requirements, guidelines that
further
narrow the scope and add a level of detail to the system design. The
Level 2
requirements address guidelines for safety, launch, emergency-return and
crew-transfer missions, mission frequency, on-orbit mission duration,
contingency cargo requirements, and docking and interfacing with the
Space
Station. The requirements also include limits on the gravitational loads
on
the crew, health monitoring of the crew, communications with the Space
Station and mission control on Earth, reliability, system lifetime, and
logistics. Each level of requirements provides a narrower parameter for
the
design of the vehicle system.

"This review is a critical step in making the Orbital Space Plane a
reality," said Dennis Smith, Orbital Space Plane program manager. "These
requirements are the instruction manual for designing the entire system
that
will provide safe, reliable access to and from the International Space
Station," he said. 

The Level 2 requirements are contained in a package of technical
documents
and plans, which include the Orbital Space Plane Systems Requirements
Document, the International Space Station Interface Requirements
Document,
the Orbital Space Plane to Expendable Launch Vehicle Interface
Definition
Document, and the Orbital Space Plane Human Rating Plan, along with
other
reference and guidance documentation. An executive summary of the Level
2
requirements is on the OSP Web site. Following review of the
documentation
for export-control and security issues, the Level 2 documentation also
will
be available online.

A System Definition Review is scheduled for November 2003. It will
include a
further, more focused evaluation of the concept design including risk
reduction and breakdown of the functional elements of the system based
on
the Level 2 requirements. The review also will set Level 3 requirements
for
the Orbital Space Plane system based on evaluation of the program
objectives
and contractor feedback.

The program is scheduled to issue a request for proposal to the three
contractor teams in November 2003. A decision to develop a full-scale
vehicle system is expected in 2004.
