SOL3167.jpgFunny Sky... - Sol 3167147 visiteLa NASA ci dice che si tratta di "false colors" (od anche "white balanced"). Va bene. Ci credo. O forse no...
Caption NASA originale: "Images of knobbly rocks and rounded hills are delighting scientists as NASA’s Curiosity Rover climbs Mount Sharp, a 5-mile-tall (such as approx. 8-Km tall) mountain within the 96-mile-wide (such as about 154-Km wide) basin of Mars’ Gale Crater. The rover’s Mast Camera, a.k.a. MastCam, highlights those features in a panorama captured on July, 3rd, 2021 (i.e. the 3167th Martian Day, or Sol, of the Mission)".
This location is particularly exciting: Spacecraft orbiting Mars show that Curiosity is now somewhere between a Region enriched with clay minerals and one dominated by salty minerals called Sulfates. The mountain’s layers in this area may reveal how the ancient environment within Gale Crater dried up over time. Similar changes are seen across the planet, and studying this Region up close (---> da vicino) has been a major long-term goal for the mission.
"The rocks here will begin to tell us how this once-wet planet changed into the dry Mars of today, and how long habitable environments persisted even after that happened,” said Abigail Fraeman, Curiosity’s deputy project scientist, at NASA’s Jet Propulsion Laboratory in Southern California".
The "Dry Mars of today"... Mmmmmhhhhh.... Are we really sure about that?!? I am not. And You?!?MareKromium

SOL3049-Mont_Mercou-2-pia24266-comboadjust-350.gifMont Mercou - Sol 3049 (GIF - Movie)126 visite"NASA’s Curiosity Mars rover used its Mastcam instrument to take the 32 individual images that make up this panorama of the outcrop nicknamed “Mont Mercou.” It took a second panorama, rolling sideways 13 feet (4 meters), to create a stereoscopic effect similar to a 3D viewfinder. The effect helps scientists get a better idea of the geometry of Mount Mercou’s sedimentary layers, as if they’re standing in front of the formation.
Both panoramas were taken on March 4, 2021, the 3,049th Martian day, or sol, of the mission, from a distance of about 130 feet (40 meters) from the cliff face, which is about 20 feet (6 meters) tall. They have been white-balanced so that the colors of the rock materials resemble how they would appear under daytime lighting conditions on Earth".MareKromium

SOL2400-PIA23242.jpgNoctilucent Clouds over Gale Crater - Sol 2400127 visiteCaption NASA Originale:"NASA's Curiosity Mars rover imaged these drifting clouds on May 7, 2019, the 2400th Martian Day, or Sol, of the mission, using its black-and-white Navigation Cameras (NavCams).
These are likely water-ice clouds about 19 miles (such as approx. 31,577 Km) above the Surface. They are also "Noctilucent" Clouds, meaning they are so high that they are still illuminated by the Sun, even when it's night at Mars' surface. Scientists can watch when light leaves the Clouds and use this information to infer their altitude".MareKromium

SOL3418-PIA25177.gifWInds... - Sol 3418 (GIF-Movie)86 visiteCaption NASA Originale:"NASA’s Curiosity Mars rover used one of its Hazard-Avoidance Cameras (Hazcams) to catch this dusty wind gust blowing overhead on March 18, 2022, the 3,418th Martian day, or sol, of the mission. Scientists believe it’s a wind gust rather than a dust devil since it doesn’t appear to have the trademark vorticity, or twisting, of a dust devil.
The series of images captured by the Hazcam is viewable in the top image; the bottom image shows the frames after they’ve been processed by change-detection software, which helps the viewer see how the wind gust moves over time.".MareKromium
