Photos: Atlas 5 rolls out for launch

Orbital Sciences Corp. announced Tuesday it selected United Launch Alliance’s Atlas 5 rocket to launch a Cygnus space station resupply mission in late 2015 while the company redesigns its Antares booster with a new engine following a catastrophic failure seconds after liftoff in October.

NASA announced Thursday nine companies that will be eligible to compete for up to $2.6 billion in contracts over the next decade to ferry scientific instruments and tech demo payloads to the moon aboard commercial robotic landers, a first step in what agency officials said will foster expanded private investment in deep space exploration and an eventual return of humans to the lunar surface.

The United Launch Alliance Atlas 5 rocket successfully flies to orbit Friday to deliver the U.S. Navy’s fifth Mobile User Objective System communications satellite.
