HiPOD 21 Mar 2022: Ancient Terrain near Nili Fossae

This region of Mars has a diversity of minerals resulting in especially colorful images.

However, the geology is complex and not easy to understand. Nili Fossae has often been on the list for potential landing sites for robotic exploration, and will likely continue to be so given its rich landscape.

HiRISE 3D: A Candidate Landing Site in Firsoff Crater

This was one of the potential sites for the Mars 2020 mission. A good example of using a 3D image to characterize landing hazards!

HiPOD 18 Mar 2022: Tracking the Zhurong Rover

The Chinese Zhurong rover landed on Mars in May 2021. (It was 14 May in the United States, but 15 May China.) This HiRISE image, acquired on 11 March 2022, shows how far the rover has traveled in the 10 months since it landed.

HiRISE 10K: Inverted Topography near Juventae Chasma

This image displays several nice examples of inverted channels near Juventae Chasma, part of the Valles Marineris system. (Click link for full cutout and additional information.)

HiRISE 3D: Watch Your Step!

This anaglyph is on a portion of the middle “island” within Hebes Chasma. Just a little more to the right and that looks like a mighty steep fall…

HiPOD 17 Mar 2022: Cool as Ice

Every winter, a layer of carbon dioxide frost (dry ice) forms on the surface of Mars. At its greatest extent in mid-winter, this frost reaches from the poles down to the middle latitudes, until it is too warm and sunny to persist.

However, small patches of dry ice are found closer to the equator on pole-facing slopes, which are colder because they receive less sunlight.

HiRISE 3D: Like a Martian Sigil

This is a previously unidentified sinuous ridge from a recent global survey of such formations. Does it possibly have a fluvial origin? This ridge is located outside of an impact crater.

HiPOD 16 Mar 2022: A Large New Slump in Eos Chasma

In geology, a slump forms a mass of loosely consolidated material or a rock layer moves a short distance down a slope. The movement is characterized by sliding along a concave-upward or planar surface.

Note to future Mars explorers: setting up camp at the base of this slope is not recommended.

HiRISE 4K: A Distinctive Rayed Impact Crater in Meridiani Planum

This “fresh” (very well-preserved) impact crater has created a radial pattern of dark rays. The image was suggested to address the question of why the rays are dark. (Click the link for full cutout and additional information.)

HiRISE 3D: A Mesa in Utopia Planitia

The futuristic version of “Little House on the Prairie,” we suppose.

HiPOD 15 Mar 2022: Defrosting Dunes in Kaiser Crater

The dark sand dune at the center of this observation is covered in a blanket of white seasonal ice in the winter. In this Martian springtime image, the western slope of the dune is partly defrosted.

HiRISE 3D: Pitted Crater Ejecta

Our goal is to expand coverage of wildly pitted crater ejecta that continues up to a hill in the southwest of this location.

HiPOD 14 Mar 2022: Dark Patches Formed by Craters

In the ancient past, this area of Mars was bombarded by impactors, forming craters of various sizes in the light-toned material. Some time after that, a darker material blanketed and covered the field, filling in the craters. Eventually, that blanketed material itself became rock.

HiRISE 3D: When the Hills Look Like Eyes

While the science goal is to document and position relationships between the troughs and knobs, we also think it looks freaky.

HiPOD 11 Mar 2022: Layered Sedimentary Rocks in Candor Chasma

Candor Chasma in central Valles Marineris is a huge, deep basin that was once filled with sediments carried by water and/or the atmosphere. Erosion has exposed the intricate structures in the layering.

HiRISE 10K: Layering in Danielson Crater

This image shows a classic example of Martian sedimentary rock in Danielson Crater. The many layers of rock are regularly spaced, forming steps; this implies a series of strong cap layers alternating with weaker layers. (Click link for full cutout and additional information.)

HiRISE 3D: Troughs North of Ganges Chasma

Ganges Chasma is part of the Valles Marineris chasma system, but is north of the main section of canyons.

HiPOD 10 Mar 2022: Deposits in Iani Chaos

This image shows layered deposits in Iani Chaos, with an enhanced color cutout. Chaos terrain forms by collapse, and the depression was partly filled by sediments carried by flowing water or from the atmosphere.

Chaos terrain is typified by mesas and valleys. The initial breakup of the land is due to tectonic forces. With time and erosion the valleys widen and the mesas grow smaller.

This image of a crater in the Utopian region can be described as what happens when heat produced from an impact comes into contact with Mars’ icy surface. (Click the link for full cutout and additional information.)
