Two suborbital rockets were successfully launched 15 seconds apart on July 4, 2013 from the NASA Wallops Flight Facility. NASA's Fourth of July rocket launches were part of the Daytime Dynamo mission, a joint project with the Japan Aerospace Exploration Agency to study how electrical currents move in Earth's ionosphere between 30 and 600 miles (48 and 965 kilometers) above the surface.
