Orbital ATK’s Antares rocket will deliver the commercial Cygnus supply ship to an orbit with an altitude between 130 miles and 179 miles within about nine minutes of liftoff from Virginia’s Eastern Shore.

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Cape Canaveral with the commercial Orbital ATK Cygnus cargo freighter headed to the International Space Station. Launch is scheduled for Tuesday at 11:11 a.m. EDT (1511 GMT).
