Current weather conditions at the launch pad include clear skies, unrestricted visibility and northwesterly winds of 9 knots. The weather outlook continues to be perfect for launch, with continued clear skies, good visibility, north-northwesterly winds of 5-10 knots and a temperature around 60 degrees F. There's a zero percent chance violating the weather rules tonight.

The first stage fuel tank of the Delta 2 rocket has been fully loaded for today's planned launch. The tank was filled with a highly refined kerosene, called RP-1, during a 19-minute, 50-second process. The next major task in the count will be loading supercold cryogenic liquid oxygen into the first stage.
The kerosene and liquid oxygen will be consumed by the stage's Pratt & Whitney Rocketdyne RS-27A main engine and twin vernier steering thrusters during the initial four-and-a-half minutes of flight.

Rapid-loading of the RP-1 tank has concluded with 9,800 gallons already aboard the rocket. Fine load is continuing to finish filling the tank.
