NASA's Curiosity Mars rover, having already driven more than 100 meters from its landing site, is stopping for several days to check out its robotic arm, project officials said this week. The rover extended its 2.1-meter arm on Wednesday for the first time since landing as engineers test out the arm and its instruments. The rover is currently stopped while these tests take place, which are expected to last six to ten days. Curiosity has driven 109 meters since landing, and it about one-quarter the way to its first major destination, Glenelg.
