CYGNSS Hurricane Mission Measures "First Light" Science Data

NASA's Cyclone Global Navigation Satellite System (CYGNSS) constellation of eight spacecraft made its "first light" measurements of the ocean surface on Jan. 4, 2017. Measurements were made by one of the eight spacecraft, and mission scientists plan to activate the science instruments on the other seven in the near future. Direct measurements are made of the GPS power reflected by the ocean surface, from which near-surface wind speed can be derived over tropical oceans and, in particular, inside hurricanes.
