Pegasus XL CYGNSS Microsats Installation on Deployment Module

Inside Building 1555 at Vandenberg Air Force Base in California, NASA’s Cyclone Global Navigation Satellite System (CYGNSS) deployment module is inspected prior to installation of eight spacecraft that will be part of the program’s constellation of spacecraft. Processing activities will prepare the spacecraft for launch aboard an Orbital ATK Pegasus XL rocket. When preparations are competed at Vandenberg, the rocket will be transported to NASA’s Kennedy Space Center in Florida attached to the Orbital ATK L-1011 carrier aircraft with in its payload fairing. CYGNSS will launch on the Pegasus XL rocket from the Skid Strip at Cape Canaveral Air Force Station. CYGNSS 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 critical role in the beginning and intensification of hurricanes.
