Photos: Final ULA mission of the year blasts off successfully

A Russian military communications satellite launched Friday from the Baikonur Cosmodrome in Kazakhstan, riding a Proton rocket and Breeze M upper stage into orbit on just the second Proton flight this year, the lowest annual flight rate for Russia’s most powerful operational launcher since the 1960s.

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.

Propelled by five strap-on solid rocket boosters and a Russian-made kerosene-fueled RD-180 main engine, a United Launch Alliance Atlas 5 rocket lifted off from Cape Canaveral Air Force Station on March 26 with the U.S. military’s sixth AEHF communications satellite.
