GROVER

Scientifically, glaciologists expect to get information about how snow accumulates layer by layer over time by using its ground-penetrating radar. Using humans, airplanes or satellites costs more than using rovers.^[3] It is expected that the rover will at least meet the performance by humans. Also, the rover should measure newly created layers that occurred in summer 2012, when higher-than-normal temperatures caused surface melting across 97 percent of the ice sheet.

In June, it is planned to send another accompanying rover with the name Cool Robot, which will be able to tow a variety of instruments for glaciological measurements. The solar panels of GROVER are like an A so that it can both get energy from the Sun, which does not set at all in the Arctic summer, and from the reflections. It will start to work at a location where the ice sheet is 2 miles (3.2 km) thick.^[3] It will use a preprogrammed route and will need only little interactions from the operator. Radar penetration will go up to 20 metres (66 ft), and it will be possible to get information about snow accumulation in the last 20 years.^[2]
