WALLOPS ISLAND, Va. (AP) - NASA is hoping weather conditions will permit the launch of two rockets from the Eastern Shore of Virginia.
NASA plans to launch the Black Brant V and Terrier-Improved Orion 15 seconds apart on Friday 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
Previous launch attempts scheduled for earlier in the week were scrubbed because of poor weather and because conditions in the ionosphere weren't what scientists needed to carry out their experiments.
