Why does HiRISE take so many repeat images of the same area?

When Martian Lava Flows Attack!

While we have coverage of the eastern side of this crater, this view of the western flank shows that lava flows poured over the crater's rim and down towards the interior.

Nighttime and daytime infrared images from THEMIS suggest a consolidated deposit in the floor of this ancient crater in Terra Sabaea, potentially with some bedrock exposure.

Fans And Polygons On Mars

This is a place where fans emerge relatively late in the Martian spring from polygonal cracks owing to the process of sublimation.

Sunken And Pitted Ejecta On Mars

The objective of this observation was to examine the edge of impact ejecta from a crater to the north-west of this area (north is up, west is to the left).

The sedimentary history of Mars is important to understanding climate change and the evolution of Mars.

Physicists led by the University of Iowa have learned how a type of aurora on Mars is formed.

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.

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.

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.

Equatorial Gullies On Mars

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.
