Oklahoma City, OK, September 28, 2006 – Rocketplane Kistler (RpK) and Andrews Space, Inc. (Andrews) announced today that they have entered into a strategic relationship to support the NASA Commercial Orbital Transportation Services (COTS) program and other applications of RpK's innovative space transportation system.

Andrews will join the RpK industrial contractor team with supporting responsibility for systems engineering and integration and safety & mission assurance. In addition, David Little, Andrews Sr. Vice President, will lead the Andrews effort as Deputy Program Manager for the K-1 Program. As part of this agreement, Andrews also plans to make a strategic investment in RpK.

Rocketplane Kistler and its K-1 space transportation system were awarded one of two Space Act Agreements under the NASA COTS program. RpK will use its fully reusable K-1 to provide cost-effective and reliable delivery and return of cargo and science payloads to and from the International Space Station. The K-1 is in an advanced stage of development and will be capable of providing end-to-end ISS servicing beginning as early as 2009.
