Officials at the American space agency say that the weather forecast for tomorrow shows 70 percent chance of clear skies. If the prediction holds, then the twin Radiation Belt Storm Probes (RBSP) could finally launch on August 30.

The identical spacecraft were originally supposed to take off from the Cape Canaveral Air Force Station (CCAFS), in Florida, last week, but technical glitches and weather violations forced NASA officials to postpone the event four times.

Currently,there is only a 30 percent chance that the weather requirements for tomorrow's launch will not be met. The launch window opens at 4:05 am EDT (0805 GMT), and will remain open for around 20 minutes or so.

The first stage of the United Launch Alliance (ULA) Atlas V delivery system that will carry RBSP to orbit has already been fueled up, and is awaiting checkout testing. At the time of this news, the launch clock was at T-16 hours, 40 minutes.
