Launch Weather Office Clay Flinn briefed the Orbital ATK CRS-4 launch team in advance of fueling the United Launch Alliance Atlas V rocket. Conditions at Cape Canaveral Air Force Station Space Launch Complex 41 have improved, as has the forecast. There now is a 70 percent chance of favorable weather for the launch of the Atlas V and Orbital ATK’s Cygnus spacecraft to the international Space Station at 4:44:57 p.m. EST.
There is a lower chance of showers or cumulus clouds and ground winds are predicted to be lower and within launch rule limits. Winds at the launch site have dropped dramatically in recent hours, but are predicted to increase slightly through the launch window.
The forecast calls for scattered clouds at 2,500 feet, scattered clouds at 30,000 feet, seven miles visibility, an isolated coastal shower, winds from the North (020) 16 knots, gusting to 20 and a temperature of 73 or 74.
There currently are no launch commit criteria violations and there is only a 30 percent chance that any will occur during the terminal countdown.
Countdown coverage here on the NASA Blog and on NASA TV will begin at 3:45 p.m. NASA TV can be streamed here or at www.nasa.gov/nasatv
