This graphic shows the variation of radiation dose measured by the Radiation Assessment Detector on NASA's Curiosity rover over about 50 sols, or Martian days, on Mars.

A chapter of the layered geological history of Mars is laid bare in this postcard from NASA's Curiosity rover. The image shows the base of Mount Sharp, the rover's eventual science destination.

Test operators monitor how NASA's Mars rover Curiosity handles driving over a ramp during a test on Sept. 10, 2010, inside the Spacecraft Assembly Facility at NASA's Jet Propulsion Laboratory, Pasa...

The Atlas V payload fairing containing NASA's Mars Science Laboratory (MSL) spacecraft rises above the floor of the Payload Hazardous Servicing Facility at Kennedy Space Center in Florida.

This animation is a shorter clip from the video "Curiosity and MAVEN Explore Mars." While Curiosity will not be able to see MAVEN as it arrives at Mars, the rover welcomes the orbiter's discoveries...

John Grotzinger, Curiosity's principal investigator, narrates an aerial tour of the rover's past, present and future traverses on the Red Planet.

This artist concept features NASA's Mars Science Laboratory Curiosity rover, a mobile robot for investigating Mars' past or present ability to sustain microbial life.

NASA's Curiosity Mars rover used a new drill method to produce a hole on February 26 in a target named Lake Orcadie. The hole marks the first operation of the rover's drill since a motor problem be...

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...

The Mars Hand Lens Imager (MAHLI) on the arm of NASA's Mars rover Curiosity was positioned about 4 inches (10 centimeters) from the surface of the "Point Lake" outcrop when it took this image of a ...

These images from the NASA Mars Reconnaissance Orbiter show several impact scars on Mars made by pieces of the NASA Mars Science Laboratory spacecraft that the spacecraft shed just before entering ...

On Cape Canaveral Air Force Station in Florida, the 197-foot-tall United Launch Alliance Atlas V rocket is in place at Space Launch Complex 41 after rolling out from the nearby Vertical Integration...

NASA's Curiosity Mars rover documented itself in the context of its work site, an area called "Rocknest Wind Drift," on the 84th Martian day, or sol, of its mission (Oct. 31, 2012).

NASA's Mars rover Curiosity drilled into this rock target, "Cumberland," during the 279th Martian day, or sol, of the rover's work on Mars (May 19, 2013) and collected a powdered sample of 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.

This image shows a close-up of track marks from the first test drive of NASA's Curiosity rover. The rover's arm is visible in the foreground.

A day after NASA's Mars rover Curiosity drilled the first sample-collection hole into a rock on Mars, the rover's Chemistry and Camera (ChemCam) instrument shot laser pulses into the fresh rock pow...

This set of images from Mars shows the handiwork of different tools on three missions to the surface of Mars.

This color panorama shows a 360-degree view of the landing site of NASA's Curiosity rover, including the highest part of Mount Sharp visible to the rover. That part of Mount Sharp is approximately ...

This illustration depicts a concept for the possible extent of an ancient lake inside Gale Crater.

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.

Curiosity is the biggest robot explorer ever to rove Mars. How do you power something like that?

This map shows the route driven by NASA's Curiosity Mars rover (blue line) and locations where the rover's ChemCam instrument detected the element boron (dots, colored by abundance of boron accordi...

This image shows the calibration target for the Chemistry and Camera instrument on NASA's Curiosity rover before it was installed on the rover and readied for launch.

This is an artist's concept of NASA's Curiosity rover tucked inside the Mars Science Laboratory spacecraft's backshell while the spacecraft is descending on a parachute toward Mars.
