6th Year Anniversary Graphic

Mars is experiencing large regional dust storms over its northern hemisphere during the past week.

This is one of the first images beamed back to Earth shortly after the Mars Exploration Rover Spirit landed on the red planet.

This 360-degree panorama was taken by "Dusty," a fully-working replica of NASA's Opportunity rover at the agency's Jet Propulsion Laboratory. The panorama was taken as part of a software test. Memb...

Dr. Ed Weiler, associate administrator, Office of Space Science, NASA Headquarters and Mars Exploration Program manager, Dr. Firouz Naderi (right) are delighted with the news of Opportunity's safe...

This artist's illustration shows NASA's four successful Mars rovers (from left to right): Sojourner, Spirit and Opportunity, and Curiosity. The image also shows the upcoming Mars 2020 rover and a h...

At an event celebrating the end of NASA’s Mars Exploration Rovers (MER) mission on Feb. 13, 2019, engineer Jennifer Trosper shared how working on the rovers Spirit and Opportunity taught her lesson...

In this photo, engineers are preparing the rover for vibration testing to ensure that it can undergo the rigors of launch and entry into the martian atmosphere. The rovers are scheduled to launch n...

Some of the team members from NASA's Mars Exploration Rover project were still in college -- or even high school -- when the rovers landed in 2004. Hear their stories of becoming part of this remar...

This is a zoomed in view on Spirit 's "Lookout" panorama on the drive up to the summit "Husband Hills."

This animation features the Mars Exploration Rover's entry into the martian atmosphere and final soft landing using airbags. (Audio: mechanical sounds only)

This image shows a portion of the rim of "Erebus Crater" in the Meridiani Planum region of Mars.

These two thumbnail images, with the ghostly dot of a faint Sun near the middle of each, are the last images NASA's Opportunity rover took on Mars.

Protected by large airbags, the lander falls away from the parachute, landing safely on Mars.

This image taken by the panoramic camera onboard Opportunity shows the rover's now-empty lander, the Challenger Memorial Station, at Meridiani Planum, Mars.

Rover 1 sits atop the deployed lander with its solar arrays and wheels stowed.

This view from the Mars Exploration Rover Opportunity's panoramic camera is a false-color composite rendering of the first seven holes that the rover's rock abrasion tool dug on the inner slope of ...

The pointy features, dubbed "Razorback," in this image may only be a few centimeters high but they generate major scientific interest.

A grooved ridge called "Rocheport" on the rim of Mars' Endeavour Crater spans this scene from the Pancam on NASA's Mars rover Opportunity. This version of the scene is presented in enhanced color t...

NASA's Mars Exploration Rover Opportunity has been working on Mars since landing inside Eagle Crater on Jan. 25, 2004 (Universal Time; evening of Jan. 24, Pacific Standard Time).

Late on Feb. 12, 2019, mission controllers at NASA’s Jet Propulsion Laboratory in Pasadena, California, sent the last commands to ask NASA’s Opportunity rover on Mars to call home. 

This self-portrait from Opportunity shows dust accumulation on the rover's solar panels as the mission approached its fifth Martian winter.

The component images for this stereo, 360-degree panorama were taken by the navigation camera on NASA's Mars Exploration Rover Opportunity after the rover drove about 97 feet (29.5 meters) during t...

The "Columbia Hills" flank Spirit's path in this view.

The designated landing site for the second Mars Exploration Rover mission is Meridiani Planum, seen here in its geological context from NASA Viking images.
