The Curiosity rover should be ready to start drilling on Mars soon, the National Aeronautics and Space Administration (NASA) said Tuesday of the most highly anticipated move since the six-wheel nuclear-powered rover landed near the Martian equator five months ago. Outlining the drilling plan, project manager Richard Cook said in Los Angeles that the team has chosen the site where Curiosity will test its drill for the first time. The location contains a diverse sample of rocks that the rover can choose from. Curiosity, on a two-year mission to determine whether the cold planet was habitable, will drive to the spot in the next several days and begin drilling in the next two weeks, mission managers said
