NASA Rover Prototype Set To Explore Greenland Ice Sheet

NASA’s newest scientific rover is set for testing May 3 through June 8 in the highest part of Greenland.

The robot known as GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, will roam the frigid landscape collecting measurements to help scientists better understand changes in the massive ice sheet.

This autonomous, solar-powered robot carries a ground-penetrating radar to study how snow accumulates, adding layer upon layer to the ice sheet over time.

Greenland’s surface layer vaulted into the news in summer 2012 when higher than normal temperatures caused surface melting across about 97 percent of the ice sheet. Scientists at NASA’s Goddard Space Flight Center in Greenbelt, Md., expect GROVER to detect the layer of the ice sheet that formed in the aftermath of that extreme melt event.

Research with polar rovers costs less than aircraft or satellites, the usual platforms.
