WALLOPS ISLAND, Va. (AP) - NASA is rescheduling its planned launch of two rockets from the Eastern Shore of Virginia to Friday.
The launch originally scheduled for Monday from Wallops Island was scrubbed again Tuesday because conditions weren't what scientists needed to carry out their experiments.
NASA plans to launch the Black Brant V and Terrier-Improved Orion 15 seconds apart in support of the Daytime Dynamo experiment.
NASA says the project is designed to study a global electrical current called the dynamo, which sweeps through the ionosphere.
The ionosphere stretches from about 30 to 600 miles above Earth. A disruption in the ionosphere can disrupt communication signals from satellites.
Each sounding rocket will go for a five-minute flight to about 100 miles up in the ionosphere.
