Mastcam 34: Shorter Focal-Length Eye of Mast Camera Pair for Mars Rover

This small ridge, about 3 feet long, appears to resist wind erosion more than the flatter plates around it. Such differences are among the traits NASA's Curiosity Mars rover is examining at selecte...

This panorama from the Mast Camera (Mastcam) of NASA's Curiosity Mars rover shows details of "Vera Rubin Ridge," which stretches about 4 miles (6.5 kilometers), end-to-end, on the northwestern flan...

The team operating NASA's Curiosity Mars rover is developing techniques that the rover might be able to use to resume drilling into rocks on Mars. In this June 2017 photo, JPL robotics engineer Vla...

This image from the right Mast Camera (Mastcam) of NASA's Curiosity Mars rover shows roughly spherical features.

The cruise stage of NASA's Mars Science Laboratory spacecraft is being prepared for final stacking of the spacecraft in this photograph from inside the Payload Hazardous Servicing Facility at NASA ...

This image from the Navigation Camera on NASA's Curiosity Mars rover shows a sandstone slab on which the rover team has selected a target, "Windjana," for close-up examination.

This is an artist's concept of the rover and descent stage for NASA's Mars Science Laboratory spacecraft during the final minute before the rover, Curiosity, touches down on the surface of Mars.

The two prominent mesas in this Aug. 18, 2016, view of Mars' "Murray Buttes" region from the Curiosity Mars rover's Mastcam are about 260 feet (about 80 meters) apart. The one on the right is about...

Holden Crater

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

This 360-degree vista was acquired on Aug. 5, 2016, by the Mastcam on NASA's Curiosity Mars rover as the rover neared features called "Murray Buttes" on lower Mount Sharp. The dark, flat-topped mes...

This movie begins with an expansive 360-degree view from NASA's Curiosity rover, showing the surrounding terrain within Gale Crater, then zooms in on the rover's deck. The full-resolution images we...

Lozenge-shaped crystals are evident in this magnified view of a Martian rock target called "Mojave," taken by the Mars Hand Lens Imager (MAHLI) instrument on the arm of NASA's Curiosity Mars rover.

Engineers put the rover through thousands of hours of testing. They did drop tests; pull tests; drive tests; load tests, and many other tests to get Curiosity ready for launch.

NASA's Mars rover Curiosity used its Mast Camera (Mastcam) to take the images combined into this mosaic of the drill area, called "John Klein."

How can you communicate with Mars spacecraft when the Sun is in the way? Learn more about 'solar conjunction' in this 60-second video.

This composite image, with magnified insets, depicts the first laser test by the Chemistry and Camera, or ChemCam,

Sandstone layers with varying resistance to erosion are evident in this Martian scene recorded by the Mast Camera on NASA's Curiosity Mars rover on Feb. 25, 2014, about one-quarter mile (about 400 ...

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.

The total distance driven by NASA's Mars rover Curiosity passed the one-mile mark a few days before the first anniversary of the rover's landing on Mars.

This self-portrait of NASA's Curiosity Mars rover shows the vehicle at the "Big Sky" site, where its drill collected the mission's fifth taste of Mount Sharp. It was taken on Oct. 6, 2015, PDT.

Ashwin Vasavada of NASA's Jet Propulsion Laboratory, Pasadena, California, became the project scientist for NASA's Mars Science Laboratory Project in January 2015.
