NASA Exploration Systems' managers will host a press conference at 4 p.m. EDT Friday, Aug. 18, to announce the organizations selected to develop and demonstrate commercial orbital transportation services. The services could pave the way for contracts to launch and deliver crew and cargo to the International Space Station.

The press conference will be in the NASA Headquarters auditorium, 300 E Street S.W., Washington, and it will air live on the Web and NASA TV. Reporters may ask questions from participating NASA locations. Reporters should coordinate with local agency centers by 4 p.m. EDT Thursday, Aug. 19 for access information.
