ICESat 2: Ice, Cloud, and Land Elevation Satellite 2 (ICESat-2)

The Ice, Cloud, and Land Elevation Satellite-2, or ICESat-2, measures the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. Launched September 15, 2018, ICESat-2 carries a photon-counting laser altimeter that allows scientists to measure the elevation of ice sheets, glaciers, sea ice and more - all in unprecedented detail.
