Digital Map of Alaska Seeing Progress

Alaska officials celebrated the progress of a long-standing mission to upgrade a dated and often-erroneous digital map of the state. The new map is being created with interferometric synthetic aperture radar (IfSAR) technology.

NASA Satellite Mission to Improve Hurricane Forecasting

NASA Satellite Mission to Improve Hurricane Forecasting

Ten years after Hurricane Katrina formed in the Atlantic Ocean, construction of NASA's next-generation hurricane-observing satellite mission is underway. NASA's Cyclone Global Navigation Satellite System (CYGNSS), a constellation of eight microsatellites, will improve hurricane forecasting by measuring ocean surface winds in and near the eye wall of tropical cyclones, typhoons and hurricanes throughout their lifecycle.
