Curiosity Observes Unusual Rock on Mars

On Mars, as on Earth, sometimes things take on an unusual appearance. One example is a shiny-looking rock seen in a recent image from NASA’s Curiosity Mars rover.

Some casual observers might see a resemblance to a car door handle, hood ornament or some other metallic object. To Ronald Sletten of the University of Washington, Seattle, a collaborator on Curiosity’s science team, the object is an interesting study in how wind and the natural elements cause erosion and other effects on various types of rocks.
