Mars Wear and Tear: Curiosity's Wheel Damage: Photos DEC 20, 2013 11:33 PM ET  //  BY  IAN O'NEILL BEFORE - SEPT. 9, 2012 (SOL 34) On Friday (Dec. 20), NASA's Mars Science Laboratory team announced that they were monitoring Curiosity's wheels. The rover's six wheels appear to have sustained accelerated damage as the one-ton rover drives over the rocky terrain inside Gale Crater. Although the aircraft-grade aluminum is designed to withstand some dents and holes, some of the rips and gashes in between the wheels' treads are causing concern. In this selection of "before and after" photos from Curiosity's raw image archive, we've pulled some photos taken by Curiosity's robotic-arm mounted MAHLI camera.

ROCKS & FOSSILS Top 10 Sinkhole Facts That Can Save Your Life MAR 1, 2013 06:30 PM ET  //  BY  CHRISTINA REED PREVIOUS  /  NEXT Sinkholes Usually Don't Kill Firemen secure the perimeter of a sinkhole that left a huge crater in the middle of a residential area in Schmalkalden, Germany, Nov. 1, 2010. No one was hurt. The hole was about 20 meters (66 feet) deep.   STEFAN THOMAS/CORBIS Sinkholes are a common feature in Florida's limestone-rich bedrock as groundwater easily dissolves the calcium carbonate into solution turning the ground into a slushy mix that washes out under the structures built on top of it. But rarely do they kill. On Thursday night, a sinkhole in Tampa opened up and swallowed the bedroom where Jeffrey Bush, 37, was sleeping. Rescue crews and his brother acted quickly to try and save him, but Friday morning, listening devices and cameras placed in the hole failed to pick up any signs of l...
