Preparations for Next Moonwalk Simulations Underway (and Underwater)
Use your mouse to explore this 360-degree view of Gediz Vallis channel, a region of Mars that NASA’s Curiosity rover surveyed before heading west to new adventures. NASA/JPL-Caltech/MSSS The rover captured a 360-degree panorama before leaving Gediz Vallis channel, a feature it’s been exploring for the past year.
NASA’s Curiosity rover is preparing for the next leg of its journey, a monthslong trek to a formation called the boxwork, a set of weblike patterns on Mars’ surface that stretches for miles. It will soon leave behind Gediz Vallis channel, an area wrapped in mystery. How the channel formed so late during a transition to a drier climate is one big question for the science team. Another mystery is the field of white sulfur stones the rover discovered over the summer.
Curiosity imaged the stones, along with features from inside the channel, in a 360-degree panorama before driving up to the western edge of the channel at the end of September.
The rover is searching for evidence that ancient Mars had the right ingredients to support microbial life, if any formed billions of years ago, when the Red Planet held lakes and rivers. Located in the foothills of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain, Gediz Vallis channel may help tell a related story: what the area was like as water was disappearing on Mars. Although older layers on the mountain had already formed in a dry climate, the channel suggests that water occasionally coursed through the area as the climate was changing.
Scientists are still piecing together the processes that formed various features within the channel, including the debris mound nicknamed “Pinnacle Ridge,” visible in the new 360-degree panorama. It appears that rivers, wet debris flows, and dry avalanches all left their mark. The science team is now constructing a timeline of events from Curiosity’s observations.
NASA’s Curiosity captured this panorama using its Mastcam while heading west away from Gediz Vallis channel on Nov. 2, 2024, the 4,352nd Martian day, or sol, of the mission. The Mars rover’s tracks across the rocky terrain are visible at right.NASA/JPL-Caltech/MSSS The science team is also trying to answer some big questions about the sprawling field of sulfur stones. Images of the area from NASA’s Mars Reconnaissance Orbiter (MRO) showed what looked like an unremarkable patch of light-colored terrain. It turns out that the sulfur stones were too small for MRO’s High-Resolution Imaging Science Experiment (HiRISE) to see, and Curiosity’s team was intrigued to find them when the rover reached the patch. They were even more surprised after Curiosity rolled over one of the stones, crushing it to reveal yellow crystals inside.
Science instruments on the rover confirmed the stone was pure sulfur — something no mission has seen before on Mars. The team doesn’t have a ready explanation for why the sulfur formed there; on Earth, it’s associated with volcanoes and hot springs, and no evidence exists on Mount Sharp pointing to either of those causes.
“We looked at the sulfur field from every angle — from the top and the side — and looked for anything mixed with the sulfur that might give us clues as to how it formed. We’ve gathered a ton of data, and now we have a fun puzzle to solve,” said Curiosity’s project scientist Ashwin Vasavada at NASA’s Jet Propulsion Laboratory in Southern California.
NASA’s Curiosity Mars rover captured this last look at a field of bright white sulfur stones on Oct. 11, before leaving Gediz Vallis channel. The field was where the rover made the first discovery of pure sulfur on Mars. Scientists are still unsure exactly why theses rocks formed here. Spiderwebs on Mars
Curiosity, which has traveled about 20 miles (33 kilometers) since landing in 2012, is now driving along the western edge of Gediz Vallis channel, gathering a few more panoramas to document the region before making tracks to the boxwork.
Viewed by MRO, the boxwork looks like spiderwebs stretching across the surface. It’s believed to have formed when minerals carried by Mount Sharp’s last pulses of water settled into fractures in surface rock and then hardened. As portions of the rock eroded away, what remained were the minerals that had cemented themselves in the fractures, leaving the weblike boxwork.
On Earth, boxwork formations have been seen on cliffsides and in caves. But Mount Sharp’s boxwork structures stand apart from those both because they formed as water was disappearing from Mars and because they’re so extensive, spanning an area of 6 to 12 miles (10 to 20 kilometers).
Scientists think that ancient groundwater formed this weblike pattern of ridges, called boxwork, that were captured by NASA’s Mars Reconnaissance Orbiter on Dec. 10, 2006. The agency’s Curiosity rover will study ridges similar to these up close in 2025.NASA/JPL-Caltech/University of Arizona This weblike crystalline structure called boxwork is found in the ceiling of the Elk’s Room, part of Wind Cave National Park in South Dakota. NASA’s Curiosity rover is preparing for a journey to a boxwork formation that stretches for miles on Mars’ surface. “These ridges will include minerals that crystallized underground, where it would have been warmer, with salty liquid water flowing through,” said Kirsten Siebach of Rice University in Houston, a Curiosity scientist studying the region. “Early Earth microbes could have survived in a similar environment. That makes this an exciting place to explore.”

Over the years, numerous mysterious events have been witnessed in the sky, defying explanation. Recently, yet another unusual sky phenomenon was observed over Southern Australia capturing attention and sparking curiosity.
Video footage reveals what appears to be a dome-shaped structure, with an even stranger detail: lightning seems to bounce off or perhaps even originate from within the dome.
The mysterious formation has led to numerous theories. Some viewers suggest it could be a unique (red) rainbow or a rare weather event like a haboob (sandstorm). Others speculate it might be the result of weather manipulation or even an energy field projected over the region.
Opinions also vary on the lightning, some say it’s bouncing off the dome, while others believe it could be emanating from within. Although it may just be an unusual natural phenomenon, the seemly strange interaction with the lightning remains unexplained.

A strange image has been circulating across social media in Thailand, showing a large, dark pillar-like structure mysteriously appearing in the sky over Ubon Ratchathani. According to the photographer, the picture was taken on Sunday, October 20, 2024, while they were trying to capture the "beautiful, colorful sky.
This peculiar sighting isn't entirely unprecedented. Similar strange phenomena have been reported before. On October 7, 2015, a mysterious "floating city" with skyscrapers appeared in the clouds over Foshan, Guangdong province in China. Again, on March 18, 2016, ghostly buildings were seen above the sea along the port of Dalian, in Liaoning Province, China, lingering in the sky for several minutes.
Most recently, on September 11, 2020, an eerie image resembling the Hogwarts School from Harry Potter was spotted hovering over modern buildings in Jinan, Shandong Province. On July 14, 2022, a bizarre occurrence was also witnessed by residents in Haikou, Hainan, where a mysterious floating city appeared in the sky.
Scientists suggest that these events are most likely optical illusions, with mirages being the leading theory. Mirages occur when light rays bend, causing distant objects or parts of the sky to appear displaced. One specific type, known as a Fata Morgana, can create towering, distorted images of distant objects, contributing to these surreal sights.
Although the sightings between 2015 and 2022 were witnessed by many, the photographer in Thailand later realized that the mysterious pillar hadn't been visible to the naked eye at the time. This discovery has led some to speculate that the phenomenon might have been caused by a Project Blue Beam test, holographic technology, or even a temporary vortex connected to a parallel universe.

A photo recently captured by NASA's Perseverance rover on Mars has revealed a surprising object that stands out from the planet's natural landscape.
The object in question looks like an artificial piece of glass or eventual a mirror, (the contours of the glass/mirror are clearly visible), partially located behind a rock formation.
The fact that it could be a mirror is because the reflection in the mirror seems to show a part of what appears to be a metallic rectangular object what lies in front of the mirror.
Both the glass/mirror and the metallic object seem to be remnants of something either abandoned or wrecked long ago. They clearly do not belong to the rover's equipment or any known NASA gear.
This discovery joins a growing list of mysterious objects found on Mars hinting at the possibility that intelligent civilizations may have once existed on the planet potentially wiped out due to a catastrophic event which made life on the planet impossible.

Reports of alien abductions first became widespread during the 1960s and 70s. Alleged abductees frequently described undergoing experimental procedures performed by extraterrestrial beings. Some even claimed that these aliens had inserted unknown objects into their bodies.
In many cases, these so-called "alien implants" are metallic and have been reported to emit radio frequency waves. Often, they are found attached to nerve endings within the body.
One of the most prominent figures in this field of research was Dr. Roger Leir, who passed away on March 14, 2014. Along with his surgical team, Dr. Leir performed 17 surgeries on individuals who claimed to have been abducted by aliens, removing 13 distinct objects suspected to be alien implants.
These objects were subjected to scientific analysis by prestigious laboratories, including Los Alamos National Labs, New Mexico Tech, and the University of California at San Diego. The findings have been puzzling, with some comparisons made to meteorite samples, and isotopic ratios in some tests suggesting materials not of Earthly origin.
One such case is that of Terry Lovelace, a former Air Force medic, who kept a disturbing secret for 40 years. In 2012, a routine x-ray revealed a small square object about the size of a fingernail which was buried deep in Terry's right leg the doctor had never see anything like it.
Then Terry suddenly remembered the terrifying experience he had tried to forget - an event during a camping trip at Devil's Den State Park that he had never spoken of, knowing no one would believe him without proof. Yet the evidence had always been there: a strange metal object embedded in his leg, something that was not man-made.
In 1977, Terry and a friend had an extraordinary encounter at Devil's Den State Park, where they witnessed a massive triangular craft. This experience resulted in missing time and unexplained injuries. Years later, Terry was faced with a difficult choice: reveal his story of alien contact or remain silent. His decision led him into conflict with powerful forces and uncovered a conspiracy that extended beyond our world.
While some remain skeptical, believing these implants are man-made and part of a secretive human agenda, Dr. Leir’s work, along with Terry Lovelace's experience at Devil’s Den and the mysterious object found in his leg, suggests that 'alien' implants may not be mere fiction.
