Cygnus Spacecraft Hauling Science to Space Station on Return-to-Flight Mission

The first launch of the private Cygnus cargo spacecraft since an October 2014 rocket explosion aims to deliver a wealth of science equipment and experiments to the International Space Station. The uncrewed Cygnus, which is built by the aerospace company Orbital ATK, is scheduled to blast off Thursday (Dec. 3) at 5:55 p.m. EST (2255 GMT) atop a United Launch Alliance Atlas V rocket from Florida's Cape Canaveral Air Force Station.
