An unmanned Atlas 5 rocket blasted off from Florida on Sunday, sending a long-awaited Orbital ATK cargo ship on its way to the International Space Station for NASA.
The Atlas 5, built and flown by United Launch Alliance (ULA), a partnership of Lockheed Martin and Boeing, lifted off from Cape Canaveral Air Force Station at 4:44 p.m. EST (2104 GMT) after three days of delays to wait out poor weather and high winds.
Sunday's launch reopens one of two U.S. supply lines to the station, a $100 billion research laboratory circling 250 miles (400 km) above Earth. Both cargo lines had been shut down by failed rocket launches.
