Preparation for Testing of Mars Landing Radar

Light material emplaced within darker vein material is seen in this view of a mineral vein at the "Garden City" site on lower Mount Sharp, Mars. The Mars Hand Lens Imager (MAHLI) on the arm of NAS...

This image shows a closeup view of the two pairs of camera lenses on a shelf. The left-hand pair are larger than the right-hand pair, go to the hazard avoidance camera, and have a larger, fish-eye ...

This stereo mosaic of images from the Navigation Camera (Navcam) on NASA's Mars rover Curiosity shows the terrain surrounding the rover's position on the 524th Martian day, or sol, of the mission (...

This graphic shows proportions of minerals identified by the Curiosity Mars rover's CheMin instrument in mudstone outcrops at "Yellowknife Bay" in 2013 and at "Murray Buttes" in 2016. For example, ...

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

The 197-foot-tall United Launch Alliance Atlas V rocket seems surrounded by lightning masts as it arrives at the launch pad at Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida...

This graphic shows the flux of radiation detected by NASA's Mars Science Laboratory on the trip from Earth to Mars from December 2011 to July 2012.

In this image, a large, six-wheeled rover sits on a concrete floor in a laboratory against a light-blue background. The rover's 'legs,' or mobility system are a medium blue color and the large, cle...

The reclosable dust cover on Curiosity's Mars Hand Lens Imager (MAHLI) was opened for the first time during the 33rd Martian day, or sol, of the rover's mission on Mars (Sept. 8, 2012), enabling MA...

This artist's concept animation depicts key events in NASA's Mars Science Laboratory mission, including launch; cruise; entry, descent & landing; and, surface operations.

This rock encountered by NASA's Curiosity Mars rover is an iron meteorite called "Lebanon," similar in shape and luster to iron meteorites found on Mars by the previous generation of rovers, Spirit...

This image contributed to an interpretation by NASA's Mars rover Curiosity science team that some of the bright particles on the ground near the rover are native Martian material.

In this activity, you’ll learn how NASA studies rocks on Earth and other planets. Then, play the role of NASA scientist to match images of "rocks" made of candy bars with their correct descriptions.
