NASA's Curiosity rover found evidence for an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here, which the science team has named "Hottah" after Hottah Lake in...

NASA's Curiosity finds that the Red Planet doesn't have the same atmosphere it used to.

This graph presents information from the NASA Curiosity Mars rover's onboard analysis of rock powder drilled from the "Buckskin" and "Greenhorn" target locations on lower Mount Sharp.

This image from NASA's Curiosity Rover shows a high-resolution view of an area that is known as Goulburn Scour, a set of rocks blasted by the engines of Curiosity's descent stage on Mars.

This map shows the path on Mars of NASA's Curiosity rover toward Glenelg, an area where three terrains of scientific interest converge.

About the size of a small toaster, the Radiation Assessment Detector will look skyward and use a stack of silicon detectors and a crystal of cesium iodide to measure galactic cosmic rays and solar ...

This image shows an example of a thin-laminated, evenly stratified rock type that occurs in the "Pahrump Hills" outcrop at the base of Mount Sharp on Mars. The Mastcam on NASA's Curiosity Mars rove...

The Curiosity Cam live video feed allows the public to watch technicians assemble and test NASA's next Mars rover in a clean room at the Jet Propulsion Laboratory, Pasadena, Calif.

The red "X" marks the spot where NASA's Curiosity rover landed on Mars.

This set of images compares test images taken by four cameras on NASA's Curiosity rover at NASA's Jet Propulsion Laboratory before launch.

This oblique view of the lower mound in Gale crater on Mars shows an area of top scientific interest for the Mars Science Laboratory mission.

Wheels were first attached to NASA's Mars Science Laboratory rover in August 2008.

Curiosity prepares for a second drilling and a tutorial on the complicated choreography to get the drill sample to her instruments.

Five years of Martian discoveries after seven minutes of terror.

This plot shows the first-ever look at the deuterium to hydrogen ratio measured from the surface of Mars, as detected by the Sample Analysis at Mars instrument, or SAM, on NASA's Curiosity rover.

A "scarecrow" rover at NASA's JPL drives over a sensor while testing a new driving algorithm. Engineers created the algorithm to reduce wheel wear on the Mars Curiosity rover.

This cropped image from NASA's Curiosity rover shows one set of marks on the surface of Mars where blasts from the descent-stage rocket engines blew away some of the surface material.

This movie from NASA's Curiosity rover shows most of the high-resolution frames acquired by the Mars Descent Imager between the jettison of the heat shield and touchdown. The video, obtained on Aug...
