Pegasus XL CYGNSS - "Days to Launch" Sign

A sign just inside the gate to NASA's Kennedy Space Center in Florida notes that in seven days a Pegasus XL rocket is scheduled to launch with eight agency Cyclone Global Navigation Satellite System, or CYGNSS, spacecraft. On Dec. 12, 2016, the Orbital ATK L-1011 Stargazer, with a Pegasus XL rocket mated to the underside of the aircraft, will take off from the Skid Strip at Cape Canaveral Air Force Station. CYGNSS will launch on the Pegasus XL rocket with the L-1011 flying off shore. CYGNSS satellites will make frequent and accurate measurements of ocean surface winds throughout the life cycle of tropical storms and hurricanes. The data that CYGNSS provides will help scientists to probe key air-sea interaction processes that take place near the core of storms, which are rapidly changing and play a crucial role in the beginning and intensification of hurricanes.
