Curiosity Aces Tests–Set to Resume Trek
September 14, 2012
After “flawlessly” completing a series of instrument tests this week, Curiosity, NASA’s newest Mars rover, was scheduled to resume its journey across the surface of the red planet Friday evening. So far, Curiosity has traveled 269 feet (82 meters) across Gale Crater, its landing site. After this short drive, Curiosity’s controllers began testing its operating systems and 10 scientific instruments. Curiosity’s next target is Glenelg, a rocky spot in the crater. The rover will study the area with a high-resolution camera and a spectrometer, which determines the level of chemical elements in rock and soil. The largest and most advanced robotic laboratory ever sent to another planet, Curiosity is designed to answer one of the most important questions in planetary science–whether Mars is, or ever has been, capable of supporting microbial life.
The rover’s prime target is Mount Sharp (also known as Aeolis Mons), a mysterious 3-mile- (5-kilometer-) high mountain in Gale Crater. Mount Sharp consists of layers of rock that may have been laid down over billions of years. Although the mountain looks similar to layered mountains on Earth, scientists do not know how it formed. As the rover scales the mountain, it will analyze the layers in an attempt to discover how Mars, which was once warmer and wetter, became so cold and dry.
