NASA says it has signed a space commercialization contract with PlanetSpace Inc. of Chicago and the Transformational Space Corp. of Reston, Va.

The National Aeronautics and Space Administration said the agreements signed Wednesday are designed to facilitate the commercialization of low-Earth orbit as capabilities are developed to transport goods and people to orbital destinations.

Under the agreements, NASA will share information that will help the companies understand projected requirements for space station crew and cargo transportation launch vehicles, spacecraft and NASA human rating criteria.

"NASA is proud to reach agreements with two more private companies dedicating their own resources toward establishment of a robust commercial launch industry," said Scott Horowitz, NASA associate administrator for exploration systems. "By stimulating the growth of commercial space enterprise, NASA will free itself to focus on long-range exploration of the moon and Mars."
