Photos: Tuesday’s Atlas 5 rollout

NOAA’s latest weather satellite, a new-generation geostationary observatory named GOES-S, landed at the Kennedy Space Center’s former space shuttle runway Monday aboard a U.S. Air Force transport jet, ready to begin final preparations for launch March 1 on top of a United Launch Alliance Atlas 5 rocket.

A rocket engine that could power United Launch Alliance’s next-generation rocket has passed a major design review, clearing the way for full-scale hotfire testing starting next year and certification for test flights in 2019, according to Aerojet Rocketdyne, the powerplant’s developer.

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.
