Photos: Atlas 5 rolls out for launch

Cape Canaveral was the departure point for more space launches in 2015 than in any year since 2003, with 17 takeoffs by Atlas, Falcon and Delta rockets hoisting U.S. military satellites, commercial payloads and cargo for the International Space Station.

An antenna-covered communications spacecraft that will bring more bandwidth and capacity to the U.S. military’s global information grid than any single satellite ever before was successfully launched Wednesday atop a Delta 4 rocket.

The launch of a Boeing-built Mexican communications satellite on a Proton rocket has been postponed after engineers discovered an anomaly on a similar spacecraft.
