Mars InSight Still Hunting Marsquakes as Power Levels Diminish

Mars InSight Covered With Dust

Dusty solar panels and darker skies are expected to bring the Mars lander mission to a close around the end of this year.

Cliffs of Crumbling, Layered Sediments On Mars

Mars Imaged by Hubble

Massive deposits of sediments rich in hydrated sulfates are found in central Valles Marineris. Such deposits on Earth are soft and easily eroded, and that appears to be true on Mars as well.

Solar Heat Is The Likely Cause Of Dust Storms On Mars

A study indicates there are seasonal energy imbalances in the amount of solar energy absorbed and released by Mars which is a likely cause of dust storms and could play an important role in understanding the climate and atmosphere of the red planet.

Dunes In Meridiani Planum On Mars

HiRISE monitors dune fields across Mars to track how they are changing.

The Caldera of Olympus Mons

HiRISE is not able to capture the entire caldera at the summit of Olympus Mons, so we try to get as many images as possible to create a potential mosaic.

Stunning Slopes In Juventae Chasma On Mars

Even though this observation was acquired after a large dust storm, there are numerous and large example of recurring slope lineae (RSL), even on the bedrock.

HiRISE Spots Slope Streaks Fanning Out On Mars

These dark streaks, also known as "slope streaks," on Mars resulted from dust avalanches.

InSight Records A Large Quake on Mars

Estimated to be magnitude 5, the quake is the biggest ever detected on another planet.

Equatorial Gullies On Mars

Although gullies are most common in the middle latitudes of Mars, they are also found in equatorial regions.

Ingenuity Is In Contact With Perseverance Rover After Communications Dropout

On Thursday, May 5, mission controllers at NASA's Jet Propulsion Laboratory received confirmation that the agency's Ingenuity Mars Helicopter had re-established communications with the Perseverance rover.

Mars Helicopter Scouts Fortun Ridge

NASA's Ingenuity Mars Helicopter recently surveyed an intriguing ridgeline near the ancient river delta in Jezero Crater.

Solving The Mystery of Frost Hiding On Mars

Scientists were baffled last year when studying images of the Martian surface taken at dawn by NASA's Mars Odyssey orbiter.

Gullies in Promethei Terra Crater On Mars

Gullies are visible on the southwest wall of this crater in Context Camera (CTX) images, but no previous HiRISE coverage for them exists.

Dunes In Nectaris Montes On Mars

Sand dunes in Valles Marineris can be impressive in size, with steep slopes that seem to climb and descend.

Recent Gullies in Equatorial Valles Marineris

Although actively-forming gullies are common in the middle latitudes of Mars, there are also pristine-looking gullies in equatorial regions.

Enigmatic Rock Layer in Mars' Gale Crater Awaits Measurements by the Curiosity Rover

Scientists have been studying the sediments within Mars' Gale crater for many years using orbital data sets, but thanks to the Curiosity rover driving across these deposits we can also obtain up-close observations and detailed measurements of the rocks, similar to field work done by geologists on Earth.
