ICESat-2 orbiting Earth: starting with global view building up ground track, then riding the satellite view, then back to a global view with full ground track ICESat-2 is a spacecraft designed to accurately measure land and ice elevations on Earth. By comparing observations from different times, scientists will be able to study changes in elevations. ICESat-2 will be in a polar orbit which will provide high coverage near the poles where ice elevations are changing relatively quickly. This visualization shows ICESat-2 s global coverage which repeats about once every 90 days.The ATLAS lidar on ICESat-2 uses 3 pairs of laser beams to measure the earth’s elevation and elevation change. As a global mission, ICESat-2 will collect data over the entire globe, however the ATLAS instrument is optimized to measure land ice and sea ice elevation in the polar regions.For more information on ICESat-2 click here.
