Curiosity Blog, Sols 4568-4569: A Close Look at the Altadena Drill Hole and Tailings
NASA’s Mars rover Curiosity acquired this image of the “Altadena” drill hole using its Mast Camera (Mastcam) on June 8, 2025 — Sol 4564, or Martian day 4,564 of the Mars Science Laboratory mission — at 13:57:45 UTC. NASA/JPL-Caltech/MSSS Written by Sharon Wilson Purdy, Planetary Geologist at the Smithsonian National Air and Space Museum
Earth planning date: Wednesday, June 11, 2025
As we near the end of our Altadena drill campaign, Curiosity continued her exploration of the Martian bedrock within the boxwork structures on Mount Sharp. After successfully delivering a powdered rock sample to both the CheMin (Chemistry and Mineralogy) and SAM (Sample Analysis at Mars) instruments, the focus for sols 4568 and 4569 was to take a closer look at the drill hole itself — specifically, the interior walls of the drill hole and the associated tailings (the rock material pushed out by the drill).
In the image above, you can see that the tone (or color) of the rock exposed within the wall of the drill hole appears to change slightly with depth, and the drill tailings are a mixture of fine powder and more solid clumps. If you compare the Altadena drill site with the 42 drill sites that came before, one can really appreciate the impressive range of colors, textures, and grain sizes in the rocks that Curiosity has analyzed over the past 12 years. Every drill hole marks a window into the past and can help us understand how the ancient environment and climate on Mars evolved over time.
In this two-sol plan, the ChemCam, Mastcam, APXS, and MAHLI instruments coordinated their observations to image and characterize the chemistry of the wall of the drill hole and tailings before we drive away from this site over the coming weekend. Outside of our immediate workspace, Mastcam created two stereo mosaics that will image the boxwork structures nearby as well as the layers within Texoli butte. ChemCam assembled three long-distance RMI images that will help assess the layers at the base of the “Mishe Mokwa” hill, complete the imaging of the nearby boxwork structures, and image the very distant crater rim (about 90 kilometers, or 56 miles away) and sky to investigate the scattering properties of the atmosphere. The environmental theme group included observations that will measure the properties of the atmosphere and also included a dust-devil survey.

The photograph was captured by the Mast Camera (Mastcam) aboard NASA’s Curiosity rover on Sol 3551 (August 2, 2022, at 20:43:28 UTC).
What stands out in the image are two objects, that appear strikingly out of place amid the natural Martian landscape of rocks and boulders. Their sharp edges, right angles, flat surfaces, and geometric symmetry suggest they may have been shaped by advanced cutting tools rather than natural erosion.
Could these ancient remnants be part of a destroyed structure or sculpture? If so, they may serve as yet another piece of evidence pointing to the possibility that Mars was once home to an intelligent civilization, perhaps even the advanced humanoid beings who, according to some theories, fled the catastrophic destruction of planet Maldek and sought refuge on the Red Planet.

Evidence points to the existence of a massive planet once located between Mars and Jupiter, known to some as Maldek. This ancient world is believed to have had a large moon, complete with oceans, an atmosphere, and possibly even life, orbiting it for millions of years.
Maldek is thought to have once been home to a highly advanced humanoid civilization before meeting a cataclysmic end, likely the result of either internal collapse, through nuclear war, technological abuse, or spiritual decline, or an external force, whether natural or engineered. Its destruction scattered debris across the solar system, forming what we now know as the asteroid belt.
As for its large moon, it was cast adrift and eventually settled into a new orbit around the Sun. Today, we know that moon as Mars.
This theory sheds light on several of Mars’ mysteries: the stark contrast between its two hemispheres, the presence of tidal bulges typically seen in moons, and the unusual nuclear isotopes in its soil, matching those produced by atomic explosions.
For decades, government scientists have suppressed this information. But the truth remains, etched into planetary scars, buried beneath ancient monuments, and encoded in the mathematical patterns of our solar system’s violent past.
Additional: According to some alternative theories, a remnant of Maldek’s civilization escaped the planet’s cataclysmic destruction, seeking refuge on Mars, a world that once pulsed with life and bore a striking resemblance to Earth. For a time, they thrived. But Mars, too, would not remain untouched. Whether through the slow unraveling of its atmosphere or the lingering shadows of interplanetary war, Mars fell into decline. And so, the survivors journeyed again, this time to Earth. Shrouded in mystery, their presence may have shaped early human consciousness, remembered through the ages as ancient gods or sky beings.

Arsia Mons, an ancient Martian volcano, was captured before dawn on May 2, 2025, by NASA’s 2001 Mars Odyssey orbiter while the spacecraft was studying the Red Planet’s atmosphere, which appears here as a greenish haze.NASA/JPL-Caltech/ASU The 2001 Odyssey spacecraft captured a first-of-its-kind look at Arsia Mons, which dwarfs Earth’s tallest volcanoes.
A new panorama from NASA’s 2001 Mars Odyssey orbiter shows one of the Red Planet’s biggest volcanoes, Arsia Mons, poking through a canopy of clouds just before dawn. Arsia Mons and two other volcanoes form what is known as the Tharsis Montes, or Tharsis Mountains, which are often surrounded by water ice clouds (as opposed to Mars’ equally common carbon dioxide clouds), especially in the early morning. This panorama marks the first time one of the volcanoes has been imaged on the planet’s horizon, offering the same perspective of Mars that astronauts have of the Earth when they peer down from the International Space Station.
Launched in 2001, Odyssey is the longest-running mission orbiting another planet, and this new panorama represents the kind of science the orbiter began pursuing in 2023, when it captured the first of its now four high-altitude images of the Martian horizon. To get them, the spacecraft rotates 90 degrees while in orbit so that its camera, built to study the Martian surface, can snap the image.
Arsia Mons is the southernmost of the three volcanoes that make up Tharsis Montes, shown in the center of this cropped topographic map of Mars. Olympus Mons, the solar system’s largest volcano, is at upper left. The western end of Valles Marineris begins cutting its wide swath across the planet at lower right.NASA/JPL-Caltech The angle allows scientists to see dust and water ice cloud layers, while the series of images enables them to observe changes over the course of seasons.
“We’re seeing some really significant seasonal differences in these horizon images,” said planetary scientist Michael D. Smith of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It’s giving us new clues to how Mars’ atmosphere evolves over time.”
Understanding Mars’ clouds is particularly important for understanding the planet’s weather and how phenomena like dust storms occur. That information, in turn, can benefit future missions, including entry, descent and landing operations.
Volcanic Giants
While these images focus on the upper atmosphere, the Odyssey team has tried to include interesting surface features in them, as well. In Odyssey’s latest horizon image, captured on May 2, Arsia Mons stands 12 miles (20 kilometers) high, roughly twice as tall as Earth’s largest volcano, Mauna Loa, which rises 6 miles (9 kilometers) above the seafloor.
The southernmost of the Tharsis volcanoes, Arsia Mons is the cloudiest of the three. The clouds form when air expands as it blows up the sides of the mountain and then rapidly cools. They are especially thick when Mars is farthest from the Sun, a period called aphelion. The band of clouds that forms across the planet’s equator at this time of year is called the aphelion cloud belt, and it’s on proud display in Odyssey’s new panorama.
“We picked Arsia Mons hoping we would see the summit poke above the early morning clouds. And it didn’t disappoint,” said Jonathon Hill of Arizona State University in Tempe, operations lead for Odyssey’s camera, called the Thermal Emission Imaging System, or THEMIS.
The THEMIS camera can view Mars in both visible and infrared light. The latter allows scientists to identify areas of the subsurface that contain water ice, which could be used by the first astronauts to land on Mars. The camera can also image Mars’ tiny moons, Phobos and Deimos, allowing scientists to analyze their surface composition.
