Holden Crater

This engineering drawing shows the arm on NASA's Curiosity's rover in its "ready- for-action" position, or "ready out" as engineers say, in addition to the position it assumes to drop off samples.

This simulation shows planned movements of the arm on NASA's Curiosity rover for round one of its robotic arm checkouts, expected to run on Sol 33 (Sept. 8, 2012). This so-called "teach point" che...

This set of images from NASA's Curiosity rover shows a patch of rock before and after it was cleaned by Curiosity's Dust Removal Tool (DRT).

This graphic offers comparisons between the amount of an organic chemical named chlorobenzene detected in the "Cumberland" rock sample and amounts of the same compound in samples from three other M...

Delta II rocket lifts off the launch pad with the Phoenix spacecraft onboard.

NASA has selected Gale crater as the landing site for the Mars Science Laboratory mission.

This video clip shows the first Martian material collected by the scoop on the robotic arm of NASA's Mars Curiosity rover, being vibrated inside the scoop after it was lifted from the ground on Oct...

One priority target for a closer look by NASA's Mars rover Curiosity before the rover departs the "Glenelg" area east of its landing site is the pitted outcrop called "Point Lake," in the upper hal...

Since landing on Mars in August 2012, NASA's Curiosity Mars rover has fired the laser on its Chemistry and Camera (ChemCam) instrument more than 100,000 times at rock and soil targets up to about 2...

The cruise stage will have support ribs, solar arrays, a radiator, and an adapter for connecting the vehicle to the rockets that will launch it from Earth.

By monitoring weather through two Martian years since landing in Gale Crater, NASA's Curiosity Mars rover has documented seasonal patterns in variables such as temperature, water-vapor content and ...

Over the years, NASA has sent five robotic vehicles, called rovers, to Mars. The names of the five rovers are: Sojourner, Spirit and Opportunity, Curiosity, and Perseverance.

This image shows the robotic arm of NASA's Mars rover Curiosity with the first rock touched by an instrument on the arm.

This scene combines seven images from the telephoto-lens camera on the right side of the Mast Camera (Mastcam) instrument on NASA's Mars rover Curiosity.

This is a view of the third (left) and fourth (right) trenches made by the 1.6-inch-wide (4-centimeter-wide) scoop on NASA's Mars rover Curiosity in October 2012.

The "Shaler" outcrop is dramatically layered, as seen in this mosaic of telephoto images from the right Mast Camera (Mastcam) on NASA's Mars rover Curiosity.

This image graphs four gases released ("evolved") when powdered rock from the target rock "Cumberland" was heated inside the Sample Analysis at Mars (SAM) instrument suite on NASA's Curiosity Mars ...

This close-up view of "Tintina" was taken by the rover's Mars Hand Lens Imager (MAHLI) on Sol 160 (Jan. 17, 2013) and shows interesting linear textures in the bright white material on the rock.

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.

On the second anniversary of NASA Curiosity on Mars, the rover navigates a sandy valley on its way to Mount Sharp

This video, taken by one of the Navigation Cameras, or Navcams, on NASA's Curiosity Mars rover, shows the rover's robotic arm as it rotates to take a selfie. A camera at the end of the arm captured...

This evenly layered rock photographed by the Mast Camera (Mastcam) on NASA's Curiosity Mars Rover on Aug. 7, 2014, shows a pattern typical of a lake-floor sedimentary deposit not far from where flo...

This view combines several frames taken by the Mast Camera (Mastcam) on NASA's Mars rover Curiosity, looking into a valley to the west from the eastern side of a dune at the eastern end of the valley.

This view of the head of the remote sensing mast on the Mars Science Laboratory mission's rover, Curiosity, shows seven of the 17 cameras on the rover.

As NASA's Curiosity heads to Mount Sharp, the rover is using autonomous navigation to pick the best route.
