NASA officials announced plans to build a new rover that would join Curiosity and Opportunity on Mars’ surface in 2020, potentially to collect soil or rock samples that could later be sent back to Earth.
The objectives are not yet set, nor are the tools the rover would wield, said John Grunsfeld, head of NASA’s Science Mission Directorate. But Grunsfeld’s remarks Tuesday raised the hopes of planetary scientists that NASA is 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 Opportunity rover, which landed on the planet in 2004. “The vehicle that John Grunsfeld just described for launch in 2020 is fully capable of doing that job.”
The announcement electrified many of the roughly 18,000 researchers attending the American Geophysical Union’s meeting this week in San Francisco.
Before Curiosity landed on Mars this summer, NASA was unsure of its future direction in exploring the solar system. Flagship missions to Mars seemed politically unpalatable after Curiosity’s $2.5 billion price tag.
But the rover’s dramatic landing and early scientific exploits have rejuvenated enthusiasm for Martian exploration.
Rather than reinventing the rover all over again, Grunsfeld said NASA will base designs for the new machine on Curiosity.
