Watch It Live: Delta Set For Launch At 6:14 PM


LIVE IMAGES: The images above are from NASA TV (left) and a live video feed at Cape Canaveral Air Force Station (right), where the Delta IV rocket and a new weather satellite are poised for launch. They will refresh to the most up-to-the-minute image every 30 seconds.

BLOGGER UPDATE, 5:29 p.m.: Less than an hour to a planned 6:14 p.m. launch and the weather is "go" at Cape Canaveral Air Force Station. Mission managers are tracking storms to the west of the Cape but all weather launch commit criteria are green at this time. Engineers are now completing standard engine steering tests in advance of the launch. The window tonight will extend to 7:14 p.m.

A Delta IV rocket and a new national weather satellite are poised for launch from Cape Canaveral Air Force Station today but mission managers are watching storms approaching the area from the west.

The 206-foot-tall rocket and its payload -- a Geostationary Operational Environmental Satellite -- remain scheduled to blast off from Launch Complex 37 during a one-hour window that opens at 6:14 p.m.

The Delta IV launch countdown so far is going along relatively smoothly with no major technical issues being worked.

Engineers fueled the rocket during a nasty thunderstorm earlier this afternoon and all propellant tanks on the two-stage rocket are being continuously topped as some of the cryogenic propellants boil off, or change from a liquid to a gaseous state.

The weather forecast calls for conditions near-identical those that caused a launch scrub on Friday. Meteorologists say there is a 70-percent chance thunderstorms will push electrically charged clouds into the area during the launch window.

The storm cells that swept through the area earlier have now moved off to the south and east and are over the Atlantic Ocean.

Two separate cells for thunderstorms, however, are approaching the Cape from the west, and their position relative to the launch pad during the launch window will determine whether United Launch Alliance will be able to press ahead with a liftoff tonight.
