Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.

When dust particles rub against each other, as they do in Martian dust storms, they can become electrified. New research shows that one particularly efficient way to move chlorine from the ground to the air on Mars is by way of reactions set off by electrical discharge generated in dust activities.

According to the professor behind a new study, this means that the first life in our solar system may have been on Mars. Thu, 17 Nov 2022 10:28:06 EST //www.koonmotors.com/releases/2022/11/221117102806.htm //www.koonmotors.com/releases/2022/11/221116090006.htm For millennia, caves have served as shelters for prehistoric humans. Caves have also intrigued scholars from early Chinese naturalists to Charles Darwin. A cave ecologist has been in and out of these subterranean ecosystems, examining the unique life forms -- and unique living conditions -- that exist in Earth's many caves. But what does that suggest about caves on other planetary bodies? In two connected studies, 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.

The parts were made by researchers with as little as 5% up to 100% Martian regolith, a black powdery substance meant to mimic the rocky, inorganic material found on the surface of the red planet. While the parts with 5% Martian regolith were strong, the 100% regolith parts proved brittle and cracked easily. Still, even high-Martian content materials would be useful in making coatings to protect equipment from rust or radiation damage.

That's much what scientists expected when they landed the rover Perseverance in the Jezero Crater, a spot chosen partly for the crater's history as a lake and as part of a rich river system, back when Mars had liquid water, air and a magnetic field. What the rover found once on the ground was startling: Rather than the expected sedimentary rocks -- washed in by rivers and accumulated on the lake bottom -- many of the rocks are volcanic in nature. Specifically, they are composed of large grains of olivine, the muddier less-gemlike version of peridot that tints so many of Hawaii's beaches dark green.

Improvements in photovoltaics are upending this calculus. A new study concludes that a solar power system would weigh less than a nuclear system, and would be sufficient to power a colony at sites over nearly half the surface.
