NASA has scheduled the next launch attempt from the Wallops Flight Facility of two suborbital sounding rockets for 9:30 a.m. to 1 p.m., Wednesday, July 13. The Black Brant V and Terrier-Improved Orion rockets, which will be launched 15 seconds apart, will be carrying experiments to study the ionosphere. Following the successful launches of two similar rockets on Sunday, launch teams today and tomorrow are preparing the next two rockets and payloads for flight.
