Video: Weather causes Atlas 5 countdown hold

Just two weeks before it flies to space, the core stage of the next Atlas 5 rocket was erected aboard the mobile launcher platform this morning by United Launch Alliance technicians to kick off a streamlined vehicle assembly that will break a record.

A replay of the United Launch Alliance Atlas 5 rocket launching the Orbital ATK’s commercial Cygnus cargo freighter to the International Space Station from Cape Canaveral, Florida.

United Launch Alliance workers encapsulated the freighter on Wednesday with the 14-foot-diameter, 45-foot-long extra extended payload fairing (XEPF) at Kennedy Space Center’s Payload Hazardous Servicing Facility.
