Curiosity Captures Stunning Views of a Changing Mars Landscape

Mars Imaged by Hubble

For the past year, NASA's Curiosity Mars rover has been traveling through a transition zone from a clay-rich region to one filled with a salty mineral called sulfate.

InSight Gets a Few Extra Weeks of Mars Science

As the power available to NASA's InSight Mars lander diminishes by the day, the spacecraft's team has revised the mission's timeline in order to maximize the science they can conduct.

A Long History of Flowing Water Recorded in Clay-Bearing Sediments on Mars

A region on Mars may have been repeatedly habitable until relatively late in Martian history, says a new paper by Planetary Science Institute Senior Scientist Catherine Weitz.

Spring Fans And Polygons On Mars

Both water and dry ice have a major role in sculpting Mars' surface at high latitudes. Water ice frozen in the soil splits the ground into polygons.

Perseverance Examines Martian Cliffs

NASA's Mars Perseverance rover acquired this image using its Left Mastcam-Z camera.

Uplifted Rocks In The Center Of A Martian Crater

Impacts forming craters excavate holes deep into the ground, exposing rocks from far below the present surface.

Sinuous Aeolis Serpens and a Crater Rim On Mars

Long, amazing, Aeolis Serpens "fluvial ridge" intersects a crater rim in this observation.

Layering in Far Eastern Candor Chasma On Mars

Context Camera images suggest that sedimentary layers here are organized into bundles of quasi-periodic beds.

Layers in Galle Crater On Mars

This image shows a layered deposit in Galle Crater, located in the southern cratered highlands.

Possible Opaline Silica in the Central Uplift of Elorza Crater On Mars

Elorza Crater is an approximately 40-kilometer diameter complex crater located at 304.8 degrees east, 8.76 degrees north, about 300 kilometers north of Coprates Chasma.

Among The Yardangs Of Medusae Fossae On Mars

Is the sinuous ridge here a "fluvial-ridge," i.e., an inversion of a fluvial sediment deposit?

NASA's MAVEN Spacecraft Resumes Science & Operations, Exits Safe Mode

NASA's Mars Atmosphere and Volatile EvolutioN, or MAVEN, mission returned to normal science and relay operations on May 28, 2022, after recovering from an extended safe mode event.

Cerberus Fossae Slopes On Mars

The fossae have long been proposed to be very tectonically active. Our goal is to look for new rockfalls that might indicate current seismic shaking.

Depressions Near Coogoon Valles On Mars

This feature likely formed by collapse.

Perseverance Studies The Wild Winds Of Jezero Crater

During its first couple hundred days in Jezero Crater, NASA's Perseverance Mars rover saw some of the most intense dust activity ever witnessed by a mission sent to the Red Planet's surface.
