Three aerospace innovators Lockheed Martin, Northrop Grumman and Orbital
Sciences Combine strengths to design and build NASA's Orbital Space Plane

DENVER, Colo., October 14, 2003 - Lockheed Martin Corporation (NYSE: LMT)
announced today that Orbital Sciences Corporation (NYSE: ORB) will join the
Lockheed Martin/Northrop Grumman team that is competing for full-scale
development of NASA's Orbital Space Plane (OSP). Lockheed Martin will lead
the team as the system prime contractor. Northrop Grumman's role will be as
principal teammate while Orbital Sciences Corporation will serve as teammate
and subcontractor. NASA is expected to choose a prime contractor team by
August 2004 for full-scale development of an OSP.

"I am very pleased that our companies have agreed to combine our
capabilities on this extremely important program for NASA," said Michael
Coats, vice president of Lockheed Martin Space Systems' Advanced Space
Transportation programs. "Together, we will be able to design, develop and
provide whole systems integration and build a safe, reliable and credibly
cost-effective Orbital Space Plane for NASA. With the combination of
Lockheed Martin, Northrop Grumman and Orbital Sciences, we will bring to
bear the most significant concentration of space flight experience and
expertise that NASA can rely upon in developing the next human space flight
system."

The Orbital Space Plane system will provide a crew rescue capability for the
International Space Station by 2008 and two-way crew transfer capability by
2012. The OSP will be launched into space aboard an Atlas V or Delta IV
launch vehicle system.

"We are very happy to be joining the Lockheed Martin team," said G. David
Low, vice president and deputy general manager of Orbital's Advanced
Programs Group. "The Lockheed Martin, Northrop Grumman and Orbital Sciences
team collectively brings a wealth of experience to the OSP program. We are
looking forward to continuing our contribution to this next human space
flight vehicle as part of a strong team. Together, we are committed to
making it safe, simple and soon."
