NASA's newest rover won't be exploring another planet, but will take a look at part of our own. Named Grover (short for Goddard Remotely Operated Vehicle for Exploration and Research), the rover will explore Greenland's ice sheets to better understand how they form, and how quickly they may be melting.
The device is solar-powered and semi-autonomous, and will embark on its first mission beginning tomorrow (May 3), and continuing until June 8. It was developed from 2010-2011 by teams of students in summer engineering boot camps at Goddard Space Flight Center in Maryland, according to a release from NASA.

the animals can, and do, make a living underground.
The study found that Iberian frogs can breed and live their entire lives in cavelike chambers, the first time this has been seen for a frog in Western Europe. The creatures were observed breeding in underground drainage compartments built beneath Portugal's Serra da Estrela Natural Park; aboveground the animals are also found in "small ponds, humid meadows and soaked fields," the authors wrote in a study.
Alaska's frigid winter refuses to release its grip on America's northernmost state.
In interior Alaska yesterday and today (May 1), residents hauled out handheld ice scrapers to excavate cars and trucks blanketed by a late-season snowstorm. The National Weather Service said 6 to 10 inches (15 to 25 centimeters) of snow fell between Monday and Wednesday in the Fairbanks region.

the world's oceans, zombie worms are quite adept at making the bones of whales and other large marine animals look like Swiss cheese.
But these worms don't have any mouthparts with which to gnaw the holes. So how do they do it? A study published in the May 1 online edition of the journal Proceedings of the Royal Society B found that rather than being "bone-drilling" worms, they're actually "bone-dissolving" worms: The worms' skin produces acid in large quantities to break down bones.

It's the first confirmed piece of debris to wash up in the state of California from the T?hoku earthquake and tsunami that hit Japan on March 11, 2011, according to the National Oceanic and Atmospheric Administration (NOAA).
