SAN FRANCISCO NASA will launch a new Mars rover in 2020, agency officials announced today (Dec. 4).
The unmanned rover's chassis and landing system will be based heavily on NASA's $2.5 billion Curiosity rover, which has been tooling around the Red Planet since August of this year, said John Grunsfeld, NASA's associate administrator for science.
"We have a whole new Mars mission, and I'm very excited about that," Grunsfeld said here today at the annual fall meeting of the American Geophysical Union.
The similarity to Curiosity's basic design should allow the agency to save significant amounts of money on the 2020 rover mission, bringing its estimated cost down to about $1.5 billion, give or take $200 million or so, Grunsfeld said. [The Boldest Mars Missions in History]
Some basic guidelines for the mission are already in place. The 2020 rover should help NASA prepare for its eventual goal of bringing samples from Mars back to Earth an effort most scientists regard as the best way to look for signs of life on the Red Planet.
"I think, no question, we want to advance sample handling, coring, analysis of samples to determine caching [of samples]," Grunsfeld said.
The new rover should also land at a site selected for its ability to preserve potential signs of life, according to Grunsfeld's presentation.
The precise details of the new mission, however, remain up in the air. They will be determined over the coming months by a "science definition team," with a call for instrument proposals from the scientific community expected by mid-summer next year.
"While 2020 may seem a long way off, it's really not," Grunsfeld said. "Curiosity was about a decade in the works."
The White House's proposed 2013 federal budget cut funding for NASA's Mars program considerably, spurring the agency to scale back and replan its Red Planet activities. The 2020 rover emerged after this fundamental rethink, and NASA should be able to mount the mission under its current budget scenario, Grunsfeld said.
