Photos: Atlas 5 rolls out for launch

Trouble has befallen the U.S. Navy’s new communications satellite that was launched from Cape Canaveral two weeks ago, suspending orbit raising maneuvers and leaving the craft half-way between its rocket deployment orbit and a circular geosynchronous orbit.

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.

The launch of NASA’s Parker Solar Probe, on the verge of kicking off a seven-year mission culminating in passages through the sun’s atmosphere, has been delayed to Aug. 6 to resolve a technical snag encountered during encapsulation of the spacecraft inside the nose shroud of its United Launch Alliance Delta 4-Heavy rocket.
