Snapshots from Atlas 5 launch

United Launch Alliance will need to lure commercial customers to ensure the economic viability of its new Vulcan rocket, which is set to debut in 2019 just as the rate of U.S. military satellite launches is due to take a dip.

A roster of representatives from the commercial space industry, astronauts, retired military officers and politicians will advise the National Space Council as the top-level government panel seeks to reshape U.S. space policy, regulations and exploration strategies.

Eric Boe, one of three astronauts assigned to the first piloted test flight of a Boeing CST-100 Starliner commercial crew ship later this year has been removed from the mission due to unspecified medical issues, NASA announced Tuesday. He will be replaced by veteran astronaut Mike Fincke.
