Experimentalists: Sorry, no oxygen required to make these minerals on Mars
Washington University in St. Louis

Scientists at Washington University in St. Louis discovered that under Mars-like conditions, manganese oxides can be readily formed without atmospheric oxygen. The study from the laboratory of Jeffrey Catalano in Arts & Sciences was published Dec. 22 in Nature Geoscience.

Scientists get first-ever sound recording of dust devils (tiny tornadoes of dust, grit) on Mars
Purdue University

When the rover Perseverance landed on Mars, it was equipped with the first working microphone on the planet’s surface. Scientists have used it to make the first-ever audio recording of an extraterrestrial whirlwind.

Microbial miners could help humans colonize the moon and Mars
University of California, Irvine

The biochemical process by which cyanobacteria acquire nutrients from rocks in Chile’s Atacama Desert has inspired engineers at the University of California, Irvine to think of new ways microbes might help humans build colonies on the moon and Mars.

Newswise: Martian Dust Devil Analogues in the Mojave Desert #ASA183

Acoustical Society of America (ASA)

Louis Urtecho and his team hope to study dust devils in the Mojave Desert on Earth, then extend the analysis to scale for the different atmosphere on Mars. Based on microbarometer data from the Mojave, they built an algorithm to look for the pressure activity indicative of a dust devil. The vortices have a distinct drop in pressure near their centers, and their pressure fluctuates to look like an electrocardiogram signal over time. The team hopes to learn more about the convective vortices and how they move, which will improve the accuracy of Martian weather models.

Newswise: Tiny Underwater Sand Dunes May Shed Light on Larger Terrestrial and Martian Formations

Tiny Underwater Sand Dunes May Shed Light on Larger Terrestrial and Martian Formations
American Institute of Physics (AIP)

In Physics of Fluids, researchers have been studying the dynamics of how crescent-shaped sand dunes are formed. Known as barchans, these formations are commonly found in various sizes and circumstances, on Earth and on Mars. Using a computational fluid dynamics approach, the team carried out simulations by applying the equations of motion to each grain in a pile being deformed by a fluid flow, showing the ranges of values for the proper computation of barchan dunes down to the grain scale.

Planetary science: Mars megatsunami may have been caused by Chicxulub-like asteroid impact
Scientific Reports

A Martian megatsunami may have been caused by an asteroid collision similar to the Chicxulub impact – which contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years ago – in a shallow ocean region, according to a study published in Scientific Reports.

Space exploration goes underground
Northern Arizona University

In two connected studies, cave ecologist Jut Wynne, along with dozens of co-authors including engineers, astrophysicists, astrobiologists and astronauts, lay out the research that needs to be done to get us closer to answering the old-age question about life beyond Earth.

New study improves the chances of finding life on Mars
Uniformed Services University of the Health Sciences (USU)

If in fact there is or has been life on Mars, it would likely still be there today, billions of years later, according to a new study published Oct. 25 in Astrobiology led by the Uniformed Services University of the Health Sciences (USU).

Layering, not liquid: Astronomers explain Mars’ watery reflections
Cornell University

Cornell astronomers believe bright reflections beneath the surface of Mars’ South Pole are not necessarily evidence of liquid water, but instead geological layers.

Martian rock-metal composite shows potential of 3D printing on Mars
Washington State University

A little Martian dust appears to go a long way. A small amount of simulated crushed Martian rock mixed with a titanium alloy made a stronger, high-performance material in a 3D-printing process that could one day be used on Mars to make tools or rocket parts.
