Taking advantage of available astronaut time, the International Space Station’s crew will cast off the commercial Orbital ATK Cygnus freighter on Sunday morning nearly six weeks ahead of schedule.

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.

The United Launch Alliance Atlas 5 rocket was transfered from its assembly building to the pad at Cape Canaveral’s Complex 41 today for Tuesday’s launch of a commercially-operated cargo ship to resupply the International Space Station.
