Alliant Techsystems and NASA plan to announce on Tuesday they have reached an agreement to accelerate the development of commercial services within the private sector that could be used to transport crew and cargo to the International Space Station and low-Earth orbit.

NASA and ATK, which is perhaps best-known for producing the solid-fuel rocket booster motors for the recently terminated space shuttle program, plan to release the details live on NASA television at 1 p.m. MDT.

Participants in the broadcast from NASA's Kennedy Space Center in Florida will include Ed Mango, NASA's commercial crew program manager; Kent Rominger, vice president of strategy and business development at ATK Aerospace; and John Schumacher, vice president of space programs for EADS North America.
