NASA is ready to test a new student-designed rover at the Summit Camp in Greenland, a research station sitting on a two-mile thick sheet of ice. The Goddard Remotely Operated Vehicle for Exploration and Research, or GROVER, carries ground-penetrating radar capable of measuring snow accumulation 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."Robots like GROVER will give us a new tool for glaciology studies," said Lora Koenig, a glaciologist at Goddard and science advisor on the project.
GROVER will be joined on the ice sheet in June by another robot, named Cool Robot, developed at Dartmouth College, Hanover, N.H., with funding from the National Science Foundation. This rover can tow a variety of instrument packages to conduct glaciological and atmospheric sampling studies.
GROVER was developed in 2010 and 2011 by teams of students participating in summer engineering boot camps at Goddard. The students were interested in building a rover and approached Koenig about whether a rover could aid her studies of snow accumulation on ice sheets. This information typically is gathered by radars carried on snowmobiles and airplanes. Koenig suggested putting a radar on a rover for this work.
