Photos: Atlas 5 on the pad at sunset

An unpiloted demonstration flight of Boeing’s Starliner crew capsule ended prematurely Sunday with a smooth airbag-cushioned predawn landing in New Mexico after a timing glitch prevented it from docking with the International Space Station, leaving some test objectives incomplete as NASA begins analyzing data to determine if astronauts should fly on the next Starliner mission.

The next satellite for the U.S. military’s communications network, this one purchased by five international allies, has arrived in Florida for its launch in March atop a Delta 4 rocket.

United Launch Alliance is preparing an Atlas 5 rocket to boost an undercover satellite into orbit for national security later this month.
