Mars rover hoping to yield more secrets, one year on

WASHINGTON, D.C.: The dazzling success of NASA’s rover Curiosity has paved the way for a human conquest of Mars, scientists say, almost one year after the groundbreaking probe first touched down on the Red Planet.

Since it successfully alighted on the Martian surface on August 6, 2012, Curiosity has gathered and beamed back to Earth a treasure trove of information expected to be vital when a manned mission to Mars eventually takes place.
