Photos: Atlas 5 rolls out for launch

A SpaceX Falcon 9 rocket, powered by a previously-flown booster, lifts off from launch pad 39A at NASA’s Kennedy Space Center in Florida at 6:27 p.m. EDT (2227 GMT) on March 30, 2017, carrying the SES 10 communications satellite. The launch marked the first time SpaceX has reused the first stage of one of its Falcon 9 rockets.

The ocean-sailing ship that transports rocket stages from United Launch Alliance’s factory to U.S. launch sites completed its latest voyage overnight, pulling into port to deliver the Atlas 5 that will send a cargo freighter to the International Space Station in March.

Persistent problems with a seismometer instrument package will keep NASA’s InSight Mars lander from departing for the red planet during a March launch period, and officials said they will consider shelving the $675 million project if the issues prove too costly to fix.
