View of NASA's CYGNSS Hurricane Mission Launch From Chase Plane
Hurricane forecasters will soon have a new tool to better understand and forecast storm intensity. A constellation of eight microsatellites, called NASA’s Cyclone Global Navigation Satellite System mission, or CYGNSS, got a boost into Earth orbit aboard an Orbital ATK Pegasus XL rocket, deployed from an L-1011 aircraft.
