The Delta 4 rocket that will launch the U.S. military’s highest capacity communications satellite ever built was rolled to the pad this week.

A day after launching from the Kennedy Space Center, NASA astronauts Doug Hurley and Bob Behnken docked with the International Space Station aboard SpaceX’s Crew Dragon spacecraft at 10:16 a.m. EDT (1416 GMT) Sunday to complete a 19-hour transit on the new commercial crew capsule.

Atlas 5 rocket hardware and a U.S. Air Force communications satellite have arrived at Cape Canaveral for United Launch Alliance’s next mission, scheduled for liftoff June 27.
