A week in Iceland wrapped up NASA's six-week airborne radar expedition to study Arctic glaciers, ice streams and map surface topography. In total, the two JPL-built radars, the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) and Glacier and Land Ice Surface Topography Interferometer (GLISTIN), imaged about 250,000 square kilometers (97,000 square miles) of land and collected about six terabytes of data, which will now be processed.
