To fly an airborne test bed instrument (MABEL) and ICESat-2

 Comparing in summer and winter, sea ice looks dramatically different. In these weekends, NASA ready to investigate the features of ice in Fairbanks, Alaska, with the help of Flying Laser Altimeter. NASA going to launches the ICESat-2; it will measure the elevation of Earth through the out pluses of green laser light and timing how long it takes individual photons to bounce off Earth’s surface and return. MABEL (Multiple Altimeter Beam Experiment) collects data with lasers and photon-detectors.

Thorsten Markus given a statement, "We need to give scientists data to enable them to develop algorithms that work during summer." He is a project scientist in ICESat-2 at NASA's Goddard Space Flight Center in Greenbelt, Maryland. With the help of ICESat-2 like data, we can study about the features like areas where snow has melted, pooling up in low spots of the sea ice or glaciers and also bare ice with no snow coverage.
