Mars' Frozen Silence: Unique Formation on the Hillside seen by NASA's Perseverance, Curiosity, MRO

On Mars, as seen by NASA's Perseverance and Curiosity Rovers, ice subjected to frigid temperatures undergoes a singular metamorphosis. Known as sublimation, the transition from solid ice directly into vapor occurs due to the planet's rarefied atmosphere and feeble solar radiation. This atmospheric condition, significantly thinner than Earth's, permits the direct conversion of frozen water or carbon dioxide into gaseous state, bypassing the liquid phase entirely.

The consequence of this unique phenomenon is a sculpted Martian landscape. Ephemeral channels known as "spiders," spanning kilometers in length, appear across ancient riverbeds and crater floors on Mars. These formations, arising over several Martian seasons, contain useful information about past water activity and the distribution of subsurface ice. Atmospheric dynamics are further entwined with sublimation.

Ascending vapor cools and condenses high above the surface, creating clouds that modulate Mars' temperature by reflecting a substantial portion of incoming sunlight back into space. In this video you can see how Martian clouds look like according to Perseverance's onboard cameras. This process influences the planet's climate through feedback loops, altering solar energy absorption and potentially impacting the rate of ice sublimation itself.

It's so amazing what the rovers have been able to do on Mars, can't wait to see what what people can do there in the hopefully not too distant future.👍👍

belo vídeo no Canal imagens incríveis impressionante de Marte pelo rolver perseverance da NASA, é um mundo deserto árido e frio chão argiloso pedras e poeiras haja mistérios

Le Soleil est toujours de la partie . Mars ❤👍

Mars has clouds as well as weather and wind! Wow!

Anstelle der Musikuntermalung, hat denn die Raumfähre keine Micros um Geräusche, aus dem Kosmus aufzunehmen und Hörbar zu machen?

Nuestro sistema solar está en constante variación en cuanto al clima y sus horizontes.

At the end of this video, I saw something that looked like a ramp. No Rover tracks on it. Not natural!

Come sentire il silenzio di Marte se fate tutto questo rumore !

[DianaLindeman-ml]

Stone ramp with walls on the sides isn't natural! The rectangular rocks aren't, either! A cliff with a layer of green rock was beautiful. When will someone tell us what those pretty green rocks are? Holes in a line done by Rover, that always includes selfies.

Is this an informational video about Mars, or an Art project? Too much filler, and useless 'music', thanks.
