SOL4992-Turtl_Rock.jpgTurtle Rock (Credits: NASA/JPL-Caltech/MSSS; Processing & License: Thomas Thomopoulos)130 visiteIs this a fossilized turtle on Mars? No. Although resembling a large Earth tortoise, this is a layered rock outcrop on Mars that is estimated to span about 15 meters, making it much larger than turtles on Earth. NASA’s robotic Curiosity rover came across this unusual mound, dubbed Miraflores, last month during its 4922nd Martian day exploring Mars. The small butte may survive because it was somehow more resistant to erosion than surrounding rock. More recent wind has now covered its top with orange Martian sand. Below the top shell, many layers of stratified rock are visible, possibly indicating a long history of intermittent wind-blown sand being deposited and then hardened by ground water. Similar wind-eroded layered landforms, such as yardangs in the Qaidam Desert of China, exist here on Earth. Curiosity and its companion rover Perseverance continue to investigate the ancient history of Mars as well as searching for signs of primeval life.
(Note: It's with great pain that I note the increasingly ridiculous color processing of images coming from Mars. However, if they and the Space Enthusiasts are happy, that's fine...)MareKromiumLug 24, 2026

SOL4887-PIA26724.pngAtacama - Sol 4877 (Credits: NASA/JPL-Caltech)127 visiteNASAs Curiosity Mars rover used its Mast Camera, or Mastcam, to capture this view of a rock nicknamed Atacama on May 6, 2026, the 4,877th Martian day, or sol, of the mission. The rock had gotten stuck to the drill on the end of Curiositys robotic arm on April 25. Engineers spent several days repositioning the arm and vibrating the drill to try and get the rock loose, finally detaching the rock on May 1.
Atacama is estimated to be 1.5 feet in diameter at its base and 6 inches thick. It would weigh roughly 28.6 pounds (13 kilograms) on Earth (and about a third of that on Mars). The circular hole produced by Curiositys drill is visible in the rock.
This mosaic is made up of eight images that were stitched together after being sent back to Earth. The color has been approximately white-balanced to resemble how the scene would appear under daytime lighting conditions on Earth.
Curiosity was built by NASAs Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASAs Science Mission Directorate in Washington as part of NASAs Mars Exploration Program portfolio. Malin Space Science Systems in San Diego built and operates Mastcam.MareKromiumMag 12, 2026

SOL4887-PIA26696_figA.pngNevado Sajama - Horizon116 visiteThe image was taken at a ridgetop site nicknamed Nevado Sajama, where Curiosity collected a rock sample using a drill on the end of its Robotic Arm.
Since May 2025, Curiosity has been exploring a region full of geologic formations called boxwork, which crisscross the surface for miles and look like giant spiderwebs when viewed from space.
The new panorama shows them as they really are: low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall and about 30 feet (9 meters) across with sandy hollows in between.MareKromiumMag 07, 2026

SOL3075_-_Don_Davis.jpgClouds over Curiosity (Credits: NASA/JPL; Credits for the additional process. and color: Don Davis)142 visiteL'immagine, in s, potrebbe anche essere carina. Ma questo tipo di colorizzazione non esiste. Nemmeno su Marte. Evidentemente anche il "Grande " Don Davis - di cui ho apprezzato molto il lavoro negli anni, sta invecchiando o si piegato alle logiche cromatiche NASA.

SOL3724-27338_PIA25740-web.jpgIcy Feather - Sol 3724153 visiteNASA’s Curiosity Mars rover captured this feather-shaped iridescent cloud just after sunset on Jan. 27, 2023, the 3,724th Martian day, or sol, of the mission. Studying the colors in iridescent clouds tells scientists something about particle size within the clouds and how they grow over time.
These clouds were captured as part of a follow-on imaging campaign to study noctilucent, or "night-shining" clouds, which started in 2021. While most Martian clouds hover no more than 37 miles (60 kilometers) above the ground and are composed of water ice, these clouds appear to be higher in elevation, where it’s very cold. That suggests these clouds are made of carbon dioxide, or dry ice.
This scene is made up of 28 individual images captured by the rover’s Mast Camera, or Mastcam. The images have been processed to emphasize the highlights.MareKromiumGiu 30, 2023

SOL0738-1581_PIA25821-web.gif159 visiteNASA’s Perseverance Mars rover used one of its navigation cameras to take a series of images of drifting clouds just before sunrise on March 18, 2023, the 738th Martian day, or sol, of the mission.
Scientists on both the Perseverance mission and NASA's Curiosity rover mission are studying the formation process of Martian clouds.
A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).
Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.MareKromiumGiu 30, 2023

SOL3730-27337_PIA25739-web.jpgMartian Twilight - Sol 3730152 visiteNASA’s Curiosity Mars Rover captured these "Sun Rays" shining through clouds at sunset on Feb. 2, 2023, the 3,730th Martian Day, or Sol, of the mission. It was the first time that sun rays, also known as crepuscular rays, have been viewed so clearly on Mars. Crepuscular is taken from the Latin word for “Twilight,” as these rays appear near Sunset or Sunrise.
These clouds were captured as part of a follow-on imaging campaign to study noctilucent, or "night-shining" clouds, which started in 2021. While most Martian clouds hover no more than 37 miles (60 kilometers) above the ground and are composed of water-ice, these clouds appear to be higher in elevation, where it’s very cold. That suggests these clouds are made of carbon dioxide, or dry ice.
