Gallery: Antares rocket explodes

Relive the steps to stack the United Launch Alliance Atlas 5 rocket at Cape Canaveral’s Vertical Integration Facility for the Orbital ATK Cygnus cargo freighter for the space station. The first stage was erected initially, followed by the interstage and Centaur stage, then the encapsulated payload.

Northrop Grumman’s Antares rocket will deliver a Cygnus supply ship into orbit Saturday to begin a two-day pursuit of the International Space Station.

Follow the Atlas 5 rocket’s ascent into orbit from Cape Canaveral’s Complex 41 launch pad with the Orbital ATK Cygnus resupply ship for the International Space Station. Launch is scheduled for Tuesday at 11:05 p.m. EDT (0305 GMT).
