Curious Mars

Mars: May 2022

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

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.

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.

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

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.

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.

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

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

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

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.

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

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

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

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

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