Live at Cape: Delta IV fueling continues

Update, 3:15 p.m.: The upper stage is being loaded with liquid oxygen propellant.

United Launch Alliance is chilling down fuel lines before beginning to load super-cold liquid hydrogen and liquid oxygen into the upper stage of a Delta IV rocket.

The rocket is still targeting a 6:14 p.m. liftoff from Launch Complex 37 at Cape Canaveral Air Force Station, carrying a next-generation weather satellite.

A weather update reported that the proximity of anvil clouds currently presents a "red" condition for launch, but that it was expected to clear within 30 to 40 minutes.

Lightning and cumulus cloud build-up had been upgraded to "green" status, meaning no obstacle to the launch.
