NASA officials plan to build a new rover that would follow Curiosity on the surface of Mars. The announcement electrified many of the roughly 18,000 researchers attending the American Geophysical Union's fall meeting this week in San Francisco. The objectives are not yet set, nor are the tools the rover would wield, said John Grunsfeld, head of NASA's Science Mission Directorate in Washington. But Grunsfeld's remarks Tuesday raised the hopes of planetary scientists that NASA would be focusing its efforts on the complex and costly task of retrieving a piece of Mars. "Collecting a cache of samples is difficult -- it requires a very capable vehicle," said Steve Squyres, lead scientist for the Mars exploration rover mission, which put Opportunity on the planet in 2004. "The vehicle that John Grunsfeld just described for launch in 2020 is fully capable of doing that job." Before Curiosity landed on Mars this summer, NASA was unsure of its future direction in exploring the solar system. Big-budget missions to Mars seemed politically unpalatable after Curiosity's $2.5-billion price tag, and no other major missions had been scheduled, even as the next launch window in 2018 approached. But the rover's dramatic landing and early scientific exploits have rejuvenated enthusiasm for Martian exploration.
