Les paysages qui entourent Perseverance sont vraiment majestueux ces temps-ci. Le rover remonte le lit asséché de la rivière Neretva, qui perce le rempart du cratère Jezero, rempart qu'on voit ici en arrière-plan. Il s'élève à plusieurs centaines de mètres de haut !

Le rover Perseverance continue de longer le lit asséché de la rivière Neretva, qui alimentait autrefois le lac du cratère Jezero. Les rides d'eau ont été remplacées par des dunes de sable, où repose Ingenuity 🚁.

Some mind-boggling details of a Martian impact crater taken by NASA's HiRISE camera onboard the Mars Reconnaissance Orbiter. This image has everything: layers, boulders, dunes, and maybe some polygonal terrain, too. The blue filter is used here to learn about morphologies, textures, and composition.
Check out this Martian panorama, captured by Curiosity two days ago, on Sol 4174. It is made of 50 adjacent images, each 1328x1184 pixels. Let's go for some zooms👇

A research team using the ChemCam instrument onboard NASA’s Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in a river, delta, or near the shoreline of an ancient lake. The results were published today in Journal of Geophysical Research: Planets.
NASA’s Curiosity has recently discovered that Mars may have been habitable billions of years ago. The rover found rocks in Mars' Gale Crater that contain a surprising amount of manganese oxide — a mineral commonly found in lakes on Earth.

Let me disabuse you of the idea that a Martian colony is the way to save mankind.
Survival on Mars is 1000x more difficult with no free flowing water, no atmosphere, no ozone, no magnetosphere, much less solar radiation to power anything including biological life.
Choosing Mars is picking the absolute worst probability to beat gambler's ruin.
Even a 3' warmer Earth is better.
The first IQ test is to stop pursuing stupid ideas as a magic bullet.
This is Alyssa Carson, a 19-year-old astronaut who has become the youngest person in history to pass all NASA's aerial tests and is preparing to become the first human to travel to Mars.
Spread this far and wide ... boost it!
Make her a household name!

The shore of Glenelg Bay at Glenelg in Lochalsh, which since 2012 has been twinned with Glenelg on Mars. This Glenelg is reached by crossing the Mam Ratagan pass or by ferry from the Isle of Skye. More pics and info: https://www.undiscoveredscotland.co.uk/glenelg/glenelg/index.html

"This phenomenon appears when spring sunlight warms layers of carbon dioxide deposited during the dark Martian winter. In turn, carbon dioxide ice in the bottom layer turns into gas, which builds up and eventually breaks through overlying ice up to 3.3 feet (1 meter) thick,"
