This mosaic from the Mast Camera on NASA's Curiosity rover shows the view looking toward the "Glenelg" area, where three different terrain types come together.

This diagram depicts rivers entering a lake. Where the water's flow decelerates, sediments drop out, and a delta forms, depositing a prism of sediment that tapers out toward the lake's interior. Pr...

On this image of the broken rock called "Tintina," color coding maps the amount of mineral hydration indicated by a ratio of near-infrared reflectance intensities measured by the Mast Camera (Mastc...

This animation depicts the location of the ChemCam instrument at the top of the mast on NASA's Mars rover Curiosity and the field of view of the instrument's camera, called the Remote Micro-Imager....

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 ...

This close-up view shows darkened radial jets caused by the impact of Curiosity's sky crane, which helped deliver the rover to the surface of Mars.

NASA's Curiosity Mars rover took this selfie at a location nicknamed "Mary Anning" after a 19th century English paleontologist. Curiosity snagged three samples of drilled rock at this site on its w...

A dust storm continues to envelop the Red Planet and Curiosity’s labs are back in action.

The payload fairing containing NASA's Mars Science Laboratory (MSL) spacecraft arrives at the Vertical Integration Facility at Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

This image from Curiosity's Mastcam shows inclined beds of sandstone interpreted as the deposits of small deltas fed by rivers flowing down from the Gale Crater rim and building out into a lake whe...

So, you want to study Mars with a lander or rover - but where exactly do you send it? Learn how scientists and engineers tackle this question in this 60-second video from NASA's Jet Propulsion Labo...

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.

This color-enhanced view shows the terrain around the rover's landing site within Gale Crater on Mars.

Scientist Jennifer Eigenbrode used a soil simulant — material that closely resembles material found on the martian surface — to test the effectiveness of a sample-preparation method that was added ...

This image of terrain inside Mars' Gale Crater and the inset of the calibration target for the Mast Camera (Mastcam) on NASA's Mars rover Curiosity illustrate how the calibration target aids resear...

Since landing on Mars in August 2012, NASA's Curiosity rover has been exploring 3-mile-high Mt. Sharp in Gale Crater.

The sinuous rock feature in the lower center of this mosaic of images recorded by the NASA Mars rover Curiosity is called "Snake River."

Engineers and technicians have been planning for months and working for weeks on the big move for NASA's Mars Curiosity rover.

Cross-bedding seen in the layers of this Martian rock is evidence of movement of water recorded by waves or ripples of loose sediment the water passed over.

The heat shield for NASA's Mars Science Laboratory is the largest ever built for a planetary mission.

This mosaic of nine images, taken by the Mars Hand Lens Imager (MAHLI) camera on NASA's Mars rover Curiosity, shows detailed texture in a conglomerate rock bearing small pebbles and sand-size parti...

This full-resolution image from NASA's Curiosity shows the turret of tools at the end of the rover's extended robotic arm on Aug. 20, 2012. The Navigation Camera captured this view.

It takes a whole team to operate Curiosity's arm. Pictured here are just a few of the team members who put their "muscle" to work every day to help operate Curiosity's arm on Mars.

After four years on Mars, Curiosity rover and her operations team are now seasoned explorers, anxious to climb to greater heights on Mount Sharp.
