NASA LAUNCH TO RESUPPLY THE ISS GETS ANOTHER NO GO AS THE ATK CYGNUS CARGO IS HELD BACK DUE TO WEATHER AND A RETRY FOR SUNDAY AFTERNOON

The launch of Orbital ATK’s Cygnus cargo spacecraft to the International Space Station has moved to Sunday at 4:44 p.m. EST, the start of a 30-minute launch window for the uncrewed spacecraft to begin it mission. Countdown and launch coverage will begin here on the NASA Blog and on NASA TV at 3:45 p.m.

Saturday’s attempt was called off because of high winds that were expected to violate launch criteria throughout the 30-minute launch window. The weather forecast for Sunday improved to a 40 percent chance of acceptable conditions at launch time.
