Mars atmosphere well protected from the solar wind

Quote:
"It has long been thought that this induced magnetosphere is insufficient to protect the Martian atmosphere," says Robin Ramstad. "However, our measurements show something different."


Research on clay formation could have implications for how to search for life on Mars

https://theconversation.com/research-on ... mars-88507

Quote:
Now a new study by a group from Brown University, Rhode Island, published in Nature, further challenges the idea that clay on Mars formed just like that on Earth. The team has done experiments suggesting that the origin of most of Mars’s clays was even earlier. They considered the likely conditions on the hot, infant Mars, 4.5 billion years ago. At that time, the primordial magma ocean that once covered the planet was still cooling, and the first crystals had floated to the surface to grow Mars’s original “primary crust”.

Curiosity Rover Spots Weird Tube-Like Structures on Mars

https://www.space.com/39294-mars-rover- ... tures.html

Quote:
Vasavada reported that the eye-catching features are very small, probably on the order of a millimeter or two (0.04 to 0.08 inches) in width, with the longest of the features stretching to roughly 5 millimeters (0.2 inches). "So, they are tiny," he told Inside Outer Space.

Think Mountain Time’s Confusing? Try Living on Martian Time

https://www.smithsonianmag.com/smithson ... 180967799/

It's a podcast. Also IIRC, a Martian second is 1.027 Earth seconds long. I did the math ages ago and only have a vague memory. But basically you can use an Earth timekeeping device but you need to push it forward a little less than 40 minutes a day.

If We Ever Get to Mars, the Beer Might Not Be Bad

Quote:
Martian soil is different from dirt on Earth. It is dense, full of iron and dries out quickly. But with some work, plants can grow well.


Keep in mind my little presentation about my martian garden a few months ago.

Mars Volcano Died at Same Time As Dinosaurs

https://www.space.com/36138-mars-volcan ... saurs.html

Quote:
"We estimate that the peak activity for the volcanic field at the summit of Arsia Mons probably occurred approximately 150 million years ago — the late Jurassic period on Earth — and then died out around the same time as Earth’s dinosaurs," Richardson said in a statement. "It’s possible, though, that the last volcanic vent or two might have been active in the past 50 million years, which is very recent in geological terms."

Tiny Crystal Shapes Get Close Look From Mars Rover

https://www.jpl.nasa.gov/news/news.php?feature=7057

Quote:
The features are about the size of a sesame seed. Some are single elongated crystals. Commonly, two or more coalesce into V-shaped "swallowtails" or more complex "lark's foot" or star configurations. "These shapes are characteristic of gypsum crystals," said Sanjeev Gupta, a Curiosity science-team member at Imperial College, London, who has studied such crystals in rocks of Scotland. Gypsum is a form of calcium sulfate. "These can form when salts become concentrated in water, such as in an evaporating lake."

Curiosity Rover Discovers Clue in 'Rock Stripes' That Mars Has Its Own Water Cycle

Quote:
"Perseverance Valley is a special place, like having a new mission again after all these years. We already knew it was unlike any place any Mars rover has seen before, even if we don't yet know how it formed, and now we're seeing surfaces that look like stone stripes. It's mysterious. It's exciting,"

If Bacteria Can Survive the Atacama, Maybe They Can Survive Mars

http://blogs.discovermagazine.com/d-bri ... -survival/

Except for the whole 1/100th Earth atmosphere pressure, increased radiation, perchlorates and other interesting compounds sprinkled throughout martian regolith.

Why... if Mars was just a little more Earthlike then maybe life on Earth could thrive on Mars!
