Bacteria that Can Make Humans Sick Could Survive on Mars

Future interplanetary explorers beware: Hitchhiking bacteria brought to Mars on human bodies might not only survive the harsh conditions on the Red Planet’s surface but also potentially thrive.

HiPOD: Ridge and Channel

The objective of this observation is to determine the nature of a ridge and channel. The ridge here is narrow and straight, and the channel has straight and curved portions. These features are common in this region. This scene is also available in Context Camera data.

HiPOD: Layers in the Walls of Nilokeras Fossa

The objective of this observation is to examine layers exposed in the wall of a trough. This image is probably the best view of layers also covered in a Context Camera image. Nilokeras Fossa is located on the margin of Kasei Valles. “Nilokeras” is Greek for “horn of the Nile.”

HiPOD: Light Toned Deposits in Arsinoes Chaos

The objective of this observation is to examine a light-toned deposit in a region of chaotic terrain. The deposit displays a rough surface, in contrast to the smoothness of the surrounding area. Some parts of the surface appear as if they were eroded by a fluid flowing north and south. This deposit may have formed in an ancient lake.

HiPOD Italiano: La storia di due crateri

I due crateri visibili in questa immagine di dettaglio hanno dimensioni simili, ma un aspetto molto diverso. Questo perché le loro rispettive età sono molto diverse. Quale cratere è il più vecchio?

HiPOD: Dust and Frost

Sand dunes in the North Polar regions of Mars show light coatings of pale orange dust blown partially across the dark basaltic sand. Around the edges of the dunes, patches of seasonal dry ice remain.

These patches will be gone soon as they sublimate (turn from ice to gas) in the summer sun. Some blocks of ice are visible at the foot of an alcove formed by a sand avalanche down the slipface of the dune.

HiPOD: Layers, Layers, Layers!

Unlike “Marsha, Marsha, Marsha!” or “Developers, developers, developers!”, this is something to *really* get excited about! Our objective is to examine these bright-toned layers in a crater wall, and see how far they extend. This crater is located within a much larger crater that might have at one time been a lake. The scene is also available in Context Camera data.

HiRISE 3D: Alluvial Fan in an Equatorial Crater

The ridges on these fans are inferred to be the preserved remains of the fluvial channels responsible for fan formation.

HiPOD: Snaking across in Deuteronilus Mensae

This location show ridges emanating from a lobate debris apron. High resolution and stereo images allows to study the morphology and topography of such ridges, allowing us to see if they are consistent with an ice flow origin.

HiRISE 3D: Comparing Layers

Compare layer sequence with higher latitude scarps to match layers and retrieve internal structure. For those of us of a certain age, these layers might resemble the edge of the VGER cloud in "Star Trek: The Motion Picture."

HiPOD: Preserved Meanders in a Jezero Crater Outlet

This scene is just west of an existing, spectacular HiRISE stereo pair. This location has incredibly well-preserved meander segments whose topography are critical for understanding the Jezero outlet paleohydrology. The scene is also visible in a Context Camera observation.

HiPOD: Crater-Delineating Mounds in Chryse Planitia

Similar HiRISE images of mounds around Chryse Planitia have revealed stunning and complex meter- and decameter-scale stratigraphy, indicative of widespread, regional-scale processes. This mound shares characteristics with those landforms, so is important to document.

HiPOD: Fossa in Orcus Patera

This public target from HiWish requested to investigate the relationship between the dark spots in the fossa and surrounding dark mantle deposits. Orcus Patera was first imaged by Mariner 4, and is a depression about 380 kilometers long and 140 kilometers wide. Its formation is unkown.

HiPOD: Etchings of a Barren World

These fascinating features are likely caused by sublimation that produces furrows in the surface and have not yet been filled-in with material. Our science goal for this observation was simple: to study wind direction in the spring in a sparsely sampled region at the South Pole of Mars.
