NASA’s Mars Perseverance rover has offered a nighttime picture of the Malgosa Crest abrasion patch positioned at “Serpentine Rapids.” This picture was captured utilizing the SHERLOC WATSON digicam on the rover’s robotic arm. The abrasion patch, measuring 5 centimetres in diameter, encompasses a notable inexperienced spot, roughly 2 millimetres broad. The picture was taken on August 19, 2024, in the course of the 1,243rd Martian day of the Mars 2020 mission.
Persevering with the Journey of Discovery
Following its sampling of the “leopard spots” at “Brilliant Angel,” Perseverance continued its exploration of this fascinating area. Roughly 20 sols later, after navigating south from Brilliant Angel throughout Neretva Vallis, the rover encountered putting purple rocks at Serpentine Rapids. Then there it created an abrasion patch in a purple rock formation generally known as “Wallace Butte.” This patch revealed an array of colors, together with white, black and inexperienced hues.
Understanding the Geological Significance
The invention of inexperienced spots stunned the rover crew. These spots, consisting of darkish cores surrounded by fuzzy, gentle inexperienced rims, current a singular geological characteristic. On Earth, purple rocks sometimes derive their hue from oxidized iron, much like the color of blood or rust. The formation of inexperienced spots, like these discovered at Wallace Butte, is widespread in historic “purple beds” on our planet. This course of happens when liquid water seeps by means of sediment, triggering a chemical response that alters the iron’s oxidation state, leading to a greenish tint.
Exploring Attainable Origins of Inexperienced Spots
Whereas such modifications can contain microbial exercise on Earth, they’ll additionally come up from decaying natural matter or interactions between sulfur and iron. Sadly, the rover was unable to analyse the inexperienced spots instantly because of house constraints. Consequently, their exact composition code
