The bright rocks in this image have minerals that contain water. These water-bearing minerals are found using the companion instrument on the MRO spacecraft called CRISM.

Curiosity Rover: Two Years On Mars

NASA's most advanced roving laboratory on Mars celebrates its second anniversary since landing inside the Red Planet's Gale Crater on Aug. 5, 2012, PDT (Aug. 6, 2012, EDT).

NASA's Opportunity Mars rover, which landed on the Red Planet in 2004, now holds the off-Earth roving distance record after accruing 25 miles (40 kilometers) of driving. The previous record was held by the Soviet Union's Lunokhod 2 rover.

This Week at NASA: Next Giant Leap

It was 45 years ago that Neil Armstrong took the small step onto the surface of the moon that changed the course of history. The Apollo missions blazed a path for human exploration to the moon and today NASA is taking its Next Giant Leap to near-Earth asteroids, Mars and beyond. As we develop and test the new tools of 21st century spaceflight on the human path to Mars, we once again will change the course of history.

NASA is celebrating the 45th anniversary of the historic Apollo 11 mission to the moon. On July 20, 1969, Neil Armstrong and Buzz Aldrin, with crewmate Michael Collins manning the command service module from lunar orbit, became the first humans on the moon -- with Armstrong's historic first step onto the lunar surface becoming a symbolic giant leap for humanity.

A New Geologic Map of Mars

Beginning in the late 1960s with the Mariner 4, 6, and 7 fly-bys, spacecraft began imaging Mars from closer perspectives.

NASA's Curiosity Mars rover used the camera at the end of its arm in April and May 2014 to take dozens of component images combined into this self-portrait where the rover drilled into a sandstone target called "Windjana."

Giant Landform on Mars

Sandy landforms formed by the wind, or aeolian bedforms, are classified by the wavelength--or length--between crests.

What will it take to land heavier spacecraft on Mars? How will engineers slow large payloads traveling at supersonic speeds in a thin Martian atmosphere? Can this be done?

Researchers have discovered on the Red Planet the largest fresh meteor-impact crater ever firmly documented with before-and-after images. The images were captured by NASA's Mars Reconnaissance Orbiter (MRO).

The rim surrounding Endeavour Crater on Mars recedes southward, then sweeps around to the east in a vista obtained by NASA's Mars Exploration Rover Opportunity.

This past November, NASA launched the Mars Atmosphere and Volatile Evolution (MAVEN) mission in the hope of understanding how and why the planet has been losing its atmosphere over billions of years.

An Active Dune Field on Mars

Nili Patera is one of the most active dune fields on Mars. As such, it is continuously monitored with the HiRISE (High Resolution Imaging Science Experiment) camera, a science instrument aboard NASA's Mars Reconnaissance Orbiter, with a new image acquired about every six weeks.

Phobos Occults Mars

Mars' moon Phobos has already been extensively observed - this image is just one example, taken in 2009 - so its occultation of Mars Express on 28 April 2014 is not expected to yield dramatic discoveries.

This image from the Navigation Camera (Navcam) on NASA's Curiosity Mars rover shows a sandstone slab on which the rover team has selected a target, "Windjana," for close-up examination and possible drilling. The target is on the approximately 2-foot-wide (60-centimeter-wide) rock seen in the right half of this view.

If desert mirages occur on Mars, "Lake Gusev" belongs among them. This come-and-go body of ancient water has come and gone more than once, at least in the eyes of Mars scientists.

Images taken by NASA's Curiosity Mars rover on April 2 and April 3 include bright spots, which might be due to the sun glinting off a rock or cosmic rays striking the camera's detector.

Late afternoon lighting produced a dramatic shadow of NASA's Mars Exploration Rover Opportunity photographed by the rover's rear hazard-avoidance camera on March 20, 2014.

NASA released Thursday an image of a comet that, on Oct. 19, will pass within 84,000 miles of Mars -- less than half the distance between Earth and our moon.

A comparison of images taken by the HiRISE camera on NASA's Mars Reconnaissance Orbiter in November 2010 and May 2013 reveal the formation of a new gully channel on a crater-wall slope in the southern highlands of Mars.
