While NASA’s Curiosity rover explores Mars, its cousin GROVER is about to embark on a mission much closer to home. From May 3 to June 8, it will roam the ice sheet of Greenland and measure the changes occurring there. The autonomous, solar-powered robot carries a ground-penetrating radar to study how snow accumulates and adds layers to the ice sheet.

During the summer of 2012, temperatures that were higher than normal caused surface melting across about 97% of the ice sheet. GROVER will detect the layer of the ice sheet that formed as a result. Researchers compare annual accumulation to the volume of ice lost to the sea each year to calculate the ice sheet’s overall mass balance and its contribution to the rise in sea levels.
