Scientists listen intently for status updates prior to Curiosity's landing.

NASA's Curiosity rover gets its first taste of Mars and finds plagioclase feldspar, pyroxene, and olivine minerals.

This engineering animation depicts the moves that NASA's rover Curiosity made on Sept. 22, 2012, when the rover touched a Martian rock with its robotic arm for the first time. Curiosity examined th...

This map shows where NASA's Mars rover Curiosity landed in August 2012 at "Bradbury Landing"; the area where the rover worked from November 2012 through May 2013 at and near the "John Klein" target...

This image from NASA's Curiosity rover shows the great diversity of grains found on the surface of a Martian rock.

NASA's Curiosity Mars rover and its tracks are visible in this view combining information from three observations by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Re...

This color image from NASA's Curiosity rover looks south of the rover's landing site on Mars towards Mount Sharp. This is part of a larger, high-resolution color mosaic made from images obtained by...

After three action-packed years on Mars, the Curiosity rover is ready to take on higher slopes of Mount Sharp.

Twenty-one times during the first 12 weeks that NASA's Mars rover Curiosity worked on Mars, the rover's Rover Environmental Monitoring Station (REMS) detected brief dips in air pressure that could ...

This Sept. 16, 2017, image from the Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover shows effects of using the rover's wire-bristled Dust Removal Tool on a rock target called "C...

On this image of the rock target "Knorr," color coding maps the amount of mineral hydration indicated by a ratio of near-infrared reflectance intensities measured by the Mast Camera (Mastcam) on NA...

This mosaic of images from the Navigation Camera (Navcam) on NASA's Mars rover Curiosity shows the scene from the rover's position on the 376th Martian day, or sol, of the mission (Aug. 27, 2013).

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

The heritage for investigations with the Dynamic Albedo of Neutrons instrument on NASA's Curiosity rover comes from NASA's Odyssey orbiter.

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...

This photo mosaic shows the scour mark, dubbed Goulburn, left by the thrusters on the sky crane that helped lower NASA's Curiosity rover to the Red Planet.

This computer-generated view based on multiple orbital observations shows Mars' Gale crater as if seen from an aircraft north of the crater.

This sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance ch...

This image taken by the Mast Camera (MastCam) on NASA's Curiosity rover highlights the interesting geology of Mount Sharp, a mountain inside Gale Crater, where the rover landed.

This image from the NASA Mars Reconnaissance Orbiter shows an impact scar on Mars made by pieces of the NASA Mars Science Laboratory spacecraft that the spacecraft shed just before entering the Mar...

This wide-angle view shows the High Bay 1 cleanroom inside the Spacecraft Assembly Facility at NASA's Jet Propulsion Laboratory, Pasadena, Calif. Specialists are working on components of the Mars S...

This view shows grains of sand where NASA's Curiosity Mars rover was driven into a shallow sand sheet near a large dune. The scene covers an area 1.3 inches wide, imaged by Curiosity's Mars Hand Le...

The Curiosity rover mission to Mars is one of NASA's most complex and incredible successes. This 45-second trailer from the Jet Propulsion Laboratory takes you from designing and testing the rover ...

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.
