Reaching New Heights to Unravel Deep Martian History!
This is an image of the rim that the Perseverance rover took on sol 383 (March 19th, 2022) when it was traversing the crater floor. Dox Castle is located at the top of the image in the far ground. NASA/JPL-Caltech/ASU The Perseverance rover is reaching new heights as it ascends the rim of Jezero crater (over 300 meters in elevation higher than the original landing site)! The rover is now enroute to its first campaign science stop Dox Castle (image in the far ground) a region of interest for its potential to host ancient Mars’ bedrock in the exposed rocks on the rim.
Impact craters like Jezero may be the key to piecing together the early geologic history of Mars, as they provide a window into the history of the ancient crust by excavating and depositing deep crustal materials above the surface. Crater rims act as keepers of ancient Martian history, uplifting and exposing the stratigraphy of these impacted materials. Additionally, extreme heat from the impact can encourage the circulation of fluids through fractures similar to hydrothermal vents, which have implications for early habitability and may be preserved in the exposed rim bedrock. With the Perseverance rover we have the potential to explore some of the oldest exposed rocks on the planet.
Exploring such diverse terrains takes a lot of initial planning! The team has been preparing for the Crater Rim Campaign these last few months by working together to map out the types of materials Perseverance may encounter during its traverse up and through the rim. Using orbital images from the High-Resolution Imaging Science Experiment (HiRISE) instrument, the science team divided the rim area into 36 map quadrants, carefully mapping different rock units based on the morphologies, tones, and textures they observed in the orbital images. Mapping specialists then connected units across the quads to turn 36 miniature maps into one big geologic map of the crater rim. This resource is being used by the team to plan strategic routes to scientific areas of interest on the rim.
On Earth, geologic maps are made using a combination of orbital images and mapping in the field. Planetary scientists don’t typically get to check their map in the field, but we have the unique opportunity to validate our map using our very own robot geologist! Dox Castle will be our first chance to do rim science – and we’re excited to search for evidence of the transition between the margin and rim materials to start piecing together the stratigraphic history of the rocks that make up the rim of Jezero crater.

In the remote wilderness of the Shoria Mountains in southern Siberia, a long-hidden secret has remained untouched for millennia. Far from the reach of modern civilization, a discovery was made that would challenge our understanding of ancient human history.
In 2013, a team of 19 researchers, led by Georgy Sidorov, embarked on an expedition to explore this mysterious region. Their destination was Gora Shoria, a mountain towering 3,600 feet above sea level in a remote part of Russia. Intrigued by reports of strange megalithic structures, the team ventured into this secluded terrain.
What they found was extraordinary: an immense super-megalith dating back roughly 100,000 years that defied conventional history. These massive stone blocks, later known as the Gornaya Shoria Megaliths, appeared to be made of granite, featuring flat surfaces and precise right angles. The most astounding detail was the weight of the stones, exceeding 3,000 tons—making them the largest megaliths ever discovered.
The arrangement of these granite blocks suggested a deliberate design, far beyond what could be explained by natural formations. The blocks were carefully stacked, reaching a height of approximately 140 feet. This raised profound questions: how were such massive stones carved, transported, and assembled in this remote and rugged landscape?
Some researchers have speculated about the existence of a pre-flood civilization, a sophisticated society wiped out by a cataclysmic event.
Also a deep, narrow vertical shaft was uncovered. The shaft, lined with parallel stone slabs, appeared to be human-made.
The walls of the shaft were straight and polished, descending 40 meters (around 130 feet) before opening into a vast underground hall, 36 meters (around 118 feet) high. These walls were constructed from large megalithic blocks, perfectly fitted with minimal gaps. Some of the stones resembled columns, reinforcing the idea of deliberate design. The full explored length of the shaft spanned over 100 meters (approximately 350 feet).
The precision and scale of this structure left no doubt that it was an artificial creation of immense proportions. The polished walls and massive blocks bore a striking resemblance to the shafts within the Great Pyramid of Khufu in Egypt, suggesting a level of architectural sophistication that defies conventional explanations.
Speculation abounds regarding the shaft’s original purpose. Some believe it served an advanced technological function or was part of a larger, undiscovered structure. The exploration team took over an hour to reach the bottom of the shaft, which required significant climbing expertise and endurance. It is believed that additional chambers and channels, still unexplored, may lie even deeper underground.
How could these gigantic 200-ton stone blocks have been assembled with such accuracy, deep underground? What kind of technology was used to construct the shaft and underground chamber?
Some researchers have speculated that it may have been part of an ancient factory, a seismological research device, or even an energy generator. Others believe it was the underground portion of a long-lost pyramid that once stood on the surface of the mountain.
Despite differing theories, we may wonder what ancient forces or lost civilizations left their mark on this remote corner of the world?

Sols 4295-4296: A Martian Moon and Planet Earth
Using an onboard focusing process, the Mars Hand Lens Imager (MAHLI) aboard NASA’s Mars rover Curiosity created this product by merging two to eight images previously taken by the MAHLI, which is located on the turret at the end of the rover’s robotic arm. Curiosity performed the merge on Sept. 4, 2024, at 06:30:48 UTC — sol 4294, or Martian day 4,294 of the Mars Science Laboratory mission. The onboard focus merge is sometimes performed on images acquired the same sol as the merge, and sometimes using pictures obtained earlier. Focus merging is a method to make a composite of images of the same target acquired at different focus positions to bring as many features as possible into focus in a single image. The MAHLI focus merge also serves as a means to reduce the number of images sent back to Earth. Each focus merge produces two images: a color, best-focus product and a black-and-white image that scientists can use to estimate focus position for each element of the best-focus product. So up to eight images can be merged, but the number of images returned to Earth is two. NASA/JPL-Caltech/MSSS Earth planning date: Wednesday, Sept. 4, 2024
Today’s two-sol plan contains the usual science blocks filled with contact science and remote science to observe and assess the geology surrounding us. However, the Mastcam team is hoping to capture a special celestial event above the Martian skyline as one of Mars’ moons, Phobos, will be in conjunction with Earth on the evening of the first sol of this plan. So everyone look up, and smile for the camera!
Coming back to our beautiful workspace, in this plan there is a focus on targeting the different colors and tones we can see in the bedrock with our suite of instruments. In the image above we can see some of these varying tones — including gray areas, lighter-toned areas, and areas of tan-colored bedrock — with an image from the MAHLI instrument, Curiosity’s onboard hand lens.
APXS is targeting “Campfire Lake,” a lighter-toned area, and “Gemini,” a more gray-toned area situated in front of the rover. MAHLI is taking a suite of close-up images of these targets too. ChemCam is then taking two LIBS measurements of “Crazy Lake” and “Foolish Lake,” both of which appear to have lighter tones. Mastcam is documenting this whole area with a workspace mosaic and an 8×2 mosaic of “Picture Puzzle,” named after the rock in the image above that was taken during the previous plan. Mastcam will also be capturing a 6×3 mosaic of an outcrop named “Outguard Spire” that has an interesting gray rim. Looking further afield, ChemCam has planned a long-distance RMI image of the yardang unit and Navcam is taking a suprahorizon movie and dust-devil survey for our continued observations of the atmosphere to round out this plan.
