It's hard to know how long ago liquid water would have been there because there's no mechanism to date the rocks that rovers find on Mars, Squyres said.
Bristling with sensors, antennas, a laser and a robotic arm, the Curiosity robot, about the size of a small SUV, is twice the length and four times the weight of any of the three prior rovers that explored Mars.
