HiPOD: Beyond Arakeen

This observation of dunes in the northern polar region of Mars was taken to monitor seasonal changes. The dark spots are the results of sublimating ice that exposes darker material under the top layer.

HiPOD: At the Margins

This observation is based on coverage over existing high-resolution CRISM data that shows a sliver of residual carbon dioxide ice and its margins.

HiPOD: Layers Northeast of Antoniadi Crater

Also visible in Context Camera image data, the objective of this observation is to examine layers near an impact crater. The shape of this particular formation is striking in its mesa-like appearance.

HiPOD: Landforms in Noachis Terra

From our public suggestion tool HiWish: “There are some elevations in the middle of what seems to be plain ground. Should be of interest to find out how it formed.”

Here’s an annotated version of our comet image.

We also want to thank our downlink and uplink teams who spent a huge amount of time working on this. Our camera was not designed to image interstellar objects 19 million miles away, but their hard work and planning paid off.

HiRISE Image of Exocomet 3I/ATLAS!

On 2 October 2025, MRO turned away from Mars to image 3I/ATLAS, only the third interstellar object ever observed passing through our solar system!

HiRISE 3D: A Possible Sulfate-Rich Deposit

Learning more about this terrain needs HiRISE stereo DTMs in areas where layers are well-exposed over wide range of elevations, such as this knob in east Candor Chasma.

HiPOD: The Shifting Winds of Hellas Plantia

This region hosts remarkably complex dunes like this field in the Hellespontus Montes mountain range. Dunes here migrate both east and west, converging at a central area.

HiPOD: A Ridge North of Mamers Valles

The objective of this observation is to take a cloesr look at a ridge. In some spots, the surfaces on either side of this ridge seem different.

HiPOD: Colorful Bedrock in the Central Uplift of an Impact Crater

This bedrock has greater compositional diversity than the surface layers, because they are from greater depths, older, jumbled, and altered, and very diverse.

HiPOD: A Colorful Landslide in Eos Chasma

A massive landslide has transported diverse rocks from the canyon’s wall layers down onto its floor, jumbling them up in the process. The range of colors implies that many other minerals are present here.

CaSSIS data show pale pinkish deposits here, which may possibly be interpreted as potential chlorides.

HiRISE 3D: Double Impact Crater!

Glacier fill in two craters now separated, but looks like the flow went north at some point, and there is a suprising lack of erosion in some areas of the rim.

HiPOD: Ridge Crossings

The simplicity of this observation contrasts with the formation we see here: two parallel, curvilinear ridges (one crossing an impact crater) that have a similar shape to other examples attributed to carbon dioxided glaciers.

In this image, the dunes are partially free of seasonal ice, with the contrast making it easy to see the ripples. Deep alcoves have been carved at the crest of the dune.
