This May 29, 2015, view of a Martian sandstone target called "Big Arm" covers an area about 1.3 inches wide in detail that shows differing shapes and colors of sand grains in the stone. It is from ...

For at least a couple of days, the science team of NASA's Mars rover Curiosity is focused on a full-bore science campaign at a tantalizing, rocky site informally called "Darwin."

This close-up view of a stone found in San Diego was taken by a testing twin -- the "life test unit" -- of the Mars Hand Lens Imager (MAHLI) camera for NASA's Mars Science Laboratory.

This image illustrates the principals of a technique called "laser-induced breakdown spectroscopy," which the Chemistry and Camera (ChemCam) instrument will use on Mars.

NASA's Curiosity rover and its powered descent vehicle pose for photographs prior to being integrated for launch at JPL's Spacecraft Assembly Facility.

This map shows the route driven by NASA's Mars rover Curiosity through the 561st Martian day, or sol, of the rover's mission on Mars (March 5, 2014).

These three versions of the same image taken by the Mast Camera (Mastcam) on NASA's Mars rover Curiosity illustrate different choices that scientists can make in presenting the colors recorded by t...
