Pegasus XL CYGNSS Second Launch Attempt

A pathfinder aircraft touches down at the Skid Strip at Cape Canaveral Air Force Station in Florida. The airplane provided photographic and video imagery of the Orbital ATK L-1011 Stargazer aircraft carrying a Pegasus XL Rocket with eight NASA Cyclone Global Navigation Satellite System, or CYGNSS, spacecraft. With the aircraft flying off shore, the Pegasus rocket was released at 8:37 a.m. EST. Five seconds later, the solid propellant engine ignited and boosted the eight hurricane observatories to orbit. The eight CYGNSS satellites will make frequent and accurate measurements of ocean surface winds throughout the life cycle of tropical storms and hurricanes.
