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.

Features on Mars may be the edge of ice sheets over 100 meters thick

Quote:
Indications of layering suggest they may trap some of the planet’s climate history.

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

https://www.nytimes.com/2018/01/12/scie ... -soil.html

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.

Methane Seepage on Mars: Where to Look and Why

http://online.liebertpub.com/doi/full/1 ... .2017.1657

Quote:
We emphasize that generated methane could be ancient or recent, and either biotic or abiotic.


No paywall for this article, fyi.

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."
