A large number of the valley networks scarring Mars’s surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today (August 3, 2020) in Nature Geoscience. The findings effectively throw cold water on the dominant “warm and wet ancient Mars” hypothesis, which postulates that rivers, rainfall, and oceans once existed on the red planet.
To reach this conclusion, lead author Anna Grau Galofre, former PhD student in the department of earth, ocean and atmospheric sciences, developed and used new techniques to examine thousands of Martian valleys. She and her co-authors also compared the Martian valleys to the subglacial channels in the Canadian Arctic Archipelago and uncovered striking similarities.
The similarity between many Martian valleys and the subglacial channels on Devon Island in the Canadian Arctic motivated the authors to conduct their comparative study. “Devon Island is one of the best analogs we have for Mars here on Earth — it is a cold, dry, polar desert, and the glaciation is largely cold-based,” says co-author Gordon Osinski, professor in Western University’s department of earth sciences and Institute for Earth and Space Exploration.
In total, the researchers analyzed more than 10,000 Martian valleys, using a novel algorithm to infer their underlying erosion processes. “These results are the first evidence for extensive subglacial erosion driven by channelized meltwater drainage beneath an ancient ice sheet on Mars,” says co-author Mark Jellinek, professor in UBC’s department of earth, ocean, and atmospheric sciences.

" All green of skin... 800 centuries ago, their bodily fluids include the birth of half-breeds. For the fundamental truth self-determination of the cosmos, for dark is the suede that mows like a harvest."
What could it mean?
The twin peaks of Mars.
I’ll vote for her. I guess I’m a “sexist”.
They didn't even use any soil samples from the many expeditions to Mars. Even if they're right that the surface is made by Ice sheets that means NOTHING to Mars ancient past.
Here is the original article NOT even a report
Early Mars was covered in ice sheets, not flowing rivers

We are suppose to not believe what we see?
Chest a minute there! Maybe she’s right.
I was better looking than the guy that played me.
BTW, I came across that movie flipping through the streaming options on Amazon Prime a couple of years ago. I’d never heard of it, but I thought I’d give it a try. That’s how poorly it was marketed.
I was blown away.
FWIW, I’m going to spend a few decades on Titan in a couple hundred years. It’s nicer than a lot of people think if you don’t mind spending a lot of time under a dome.

People from earth think he is representative of us. He’s a mental institution escapee.
It would be like your Joe Biden being used by us as a typical specimen for your world. I say “your” because I’m only here on a 400 year assignment and then its back home to the wife and kids.
These long distance relationships are killer, even with the portable conjugal hyper-chambers.
Yup. A sure sign to be skeptical.
All located, no doubt, in Chappaqua.......
Nah. It’s next to the shower in my bathroom. :)

Each.
And they have your time travel machine as well.......allows them to return to the glory days of Epstein's island......:-)
