In the Mission Director's Center at Cape Canaveral Air Force Station, Greg Robinson, deputy associate administrator for Programs in the NASA Science Mission Directorate, right, congratulates, Tim Dunn, who was launch director for launch of eight Cyclone Global Navigation Satellite System, or CYGNSS, spacecraft. The 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 enable 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.
