A metallic, turtle shaped boulder sitting upright in the dusty floor of Jezero Crater has abruptly become the most talked about stone in the solar system. NASA’s Perseverance rover has spotted a rock on Mars that appears to be an interplanetary visitor, a chunk of iron and nickel that does not match the local terrain and may have formed deep inside an ancient asteroid before crash landing on the Red Planet.
The find is more than a visual oddity. It offers scientists a rare natural sample of material forged far from Jezero, a chance to probe how fragments from elsewhere in the solar system shaped Mars, and a fresh reminder that the planet Perseverance is exploring is still being rewritten by impacts from space.
The moment Perseverance met a stranger
When NASA’s Mars Perseverance rover rolled across a relatively flat patch of Jezero Crater, mission scientists expected more of the same fractured bedrock and dust they had cataloged for years. Instead, cameras locked onto a solitary, sculpted block that stood higher than its surroundings and gleamed with a metallic sheen, prompting the team to describe it as a “stranger in our midst” in an official mission blog. The object’s isolated position and unusual texture immediately set it apart from the crater floor, which is dominated by low lying, fragmented rocks.
Coverage of the discovery on Nov 18, 2025 framed the encounter as a surprise even for a mission built to find the unexpected, with reports noting that NASA scientists made an unexpected discovery on Mars when they spotted the odd rock while continuing their search for signs of life during routine operations. In a separate account of the same timeline, Nov 18, 2025 was also cited as the moment NASA scientists made an unexpected discovery on Mars, a strange shaped rock given the name “Phippsaksla” that may not have formed on the planet at all, underscoring how quickly the object shifted from curiosity to potential meteorite candidate in mission briefings.
Why this rock “doesn’t belong” on Mars
From the outset, researchers stressed that the rock’s chemistry and shape do not fit the story told by the surrounding terrain. Reports on Nov 18, 2025 described how NASA discovers rock on Mars that shouldn’t be there and highlighted that scientists think it is a visitor from outer space, a conclusion driven by its iron rich composition and the way it stands apart from the local bedrock in Jezero Crater rather than blending in. That sense of otherness is what led mission scientists to say the rock “does not belong” to the planet’s native geology.
Instrument readings strengthened that impression. According to mission summaries dated Nov 18, 2025, the shiny rock nicknamed “Phippsaksla” showed a metallic signature that pointed to a high concentration of iron and nickel, the same family of elements that dominate many meteorites and even Earth’s core, which is why scientists quickly began referring to it as a mysterious visitor from outer space on the Martian surface rather than a local lava remnant. That combination of composition and context is what sets this object apart from the countless ordinary stones Perseverance has driven past.
Meet Phippsaksla, the 80 centimeter mystery
Scientists have now settled on a working identity for the object: a potential meteorite named Phippsaksla. Detailed descriptions on Nov 18, 2025 characterize it as an 80-centimeter (31-inch) wide rock, named Phippsaksla, that likely formed elsewhere in the solar system before ending up in Jezero Crater, a scale that makes it a substantial boulder rather than a small pebble sitting alone on the plain. That size, combined with its upright posture, helps explain why it caught the rover team’s eye so quickly.
NASA’s own technical notes add visual context, explaining that NASA’s Mars Perseverance rover acquired this image of the unusually shaped rock at a local solar time of 12:45:41, capturing its layered, sculpted sides and the way it rises above the flatter surroundings in crisp detail. A second analysis on Nov 18, 2025 reiterates that the 80-centimeter (31-inch) wide rock, named Phippsaksla, may have formed elsewhere in the solar system, reinforcing the idea that this is not just an odd local boulder but a fragment of a much larger body that once orbited the Sun far from Jezero before impact.
How scientists know it is probably a meteorite
To move from hunch to hypothesis, the Perseverance team leaned on the rover’s suite of spectrometers and cameras. Reports on Nov 19, 2025 describe how NASA scientists have been shocked by the discovery of a mysterious rock on Mars that appears to “not belong” to the planet, and note that its composition and texture match what researchers expect from a meteorite rather than from volcanic or sedimentary rocks native to Jezero based on previous surveys. That early verdict is grounded in the same kind of elemental fingerprinting that has identified iron nickel meteorites on Earth.
Video explainers released on Nov 22, 2025 have amplified that message for a wider audience, with one segment titled around a NASA rover finding a mysterious object on Mars that is not from the Red Planet and emphasizing that the object’s metallic makeup and isolated setting point strongly to a meteorite origin rather than a local rock uplifted by erosion in the crater floor. Together, these analyses sketch a consistent picture: Phippsaksla’s chemistry, structure, and context all line up with the profile of a meteorite that fell from space and has been slowly weathered by Martian winds ever since.
Why Phippsaksla matters for the Perseverance mission
For the Perseverance team, this is not just a photogenic anomaly, it is a scientific opportunity that fits squarely within the rover’s broader mandate. Earlier coverage on Nov 14, 2025 pointed out that only about 60,000 m meteorites have been identified on Earth to date and noted that the oddly sculpted rock, nicknamed Phippsaksla, marks the first such discovery for Perseverance, giving the mission a new class of target to study alongside its usual sedimentary cores in Jezero. That rarity alone makes the rock a valuable data point for understanding how often large meteorites survive on the Martian surface.
Commentary around Nov 22, 2025 has gone further, arguing that this discovery adds another intriguing chapter to the search for clues beyond Earth, framing Phippsaksla as part of a broader pattern of finds that help scientists reconstruct the bombardment history of Mars and the delivery of materials from elsewhere in the solar system to its surface. In that sense, the rock is not a distraction from Perseverance’s hunt for ancient life but a complementary thread, one that can reveal what kinds of extraterrestrial ingredients have been mixed into the Martian environment over time.
Inside the rock: iron, nickel and an asteroid’s core
Early compositional readings suggest that Phippsaksla is rich in metals that rarely dominate native Martian rocks. Analyses published on Nov 17, 2025 explain that NASA’s Perseverance rover came across a rock with a high concentration of iron and nickel elements, according to the early analysis, and that this chemistry is consistent with material that solidified in the interior of a differentiated asteroid sometime in the distant past before being shattered. That kind of metal heavy mix is what makes iron nickel meteorites so prized by planetary scientists.
Social media posts on Nov 20, 2025 added a visual twist, noting that the rock is only about 31 inches wide and describing its strange, green tinted surface as captured by NASA’s Perseverance rover on Mars, while also highlighting that its composition was studied with instruments built by teams at CNRS/IRAP/IAS/LPG to read its elemental spectrum. A separate video released on Nov 21, 2025 goes even further, stating that NASA’s Perseverance rover discovers a rare iron-nickel meteorite, named “Pip Sakla,” on Mars, indicating a journey from an asteroid’s core, a description that aligns with the idea that this rock preserves material from deep inside a long vanished parent body rather than its surface.
How Phippsaksla fits into Mars’s weird rock collection
As striking as Phippsaksla is, it is not the first time a rover has stumbled across a rock that looks out of place on Mars. NASA’s own retrospective on Nov 12, 2025 notes that this is not the first time a rover has encountered an exotic rock on Mars and points out that The Curiosity rover has identified many iron rich meteorites and unusual boulders that did not match their surroundings, building a catalog of oddities that Phippsaksla now joins as a new member. That history shows that Mars is a magnet for debris from elsewhere in the solar system.
Perseverance itself has been adding to that collection for years. A detailed feature on weird Martian rocks highlights how NASA’s Perseverance rover finds strange rocks on Mars and compares them with earlier discoveries by Curiosity, with PHOTOGRAPH captions crediting NASA, JPL, CALTECH, LANL, and CNES for documenting everything from layered sediments to odd, knobbly boulders that defy easy explanation across multiple missions. Another survey of unusual stones points to a rock informally named ‘Freya Castle,’ affectionately called ‘zebra rock’ for obvious reasons, as an example of how rover teams routinely flag and study outliers that might reveal new chapters in Mars’s geological story even when they are not meteorites.
From Jezero Crater to the search for life
Although Phippsaksla itself is unlikely to host evidence of biology, its discovery is intertwined with Perseverance’s broader search for signs of life in Jezero Crater. A detailed explainer shared on Oct 16, 2025 describes how Oct, in a video dated October 17, scientists argued that NASA’s Perseverance rover may have found the clearest hints of past habitability in a strange speckled rock in Jezero Crater, underscoring how carefully the team scrutinizes any unusual stone for chemical clues that might preserve organic signatures. In that context, a metal rich meteorite offers a different but still valuable window into the planet’s history.
Longer term, Phippsaksla could help researchers refine models of how material from asteroids and comets has altered Mars’s surface chemistry, which in turn shapes where they look for ancient biosignatures. A feature on Nov 23, 2025 notes that What makes Phippsakslan unique in this geological setting is its composition; being rich in iron and nickel, it appears to have arrived from outside the local crust, which could have implications for how often such impacts deliver new elements to the Martian environment over billions of years. That influx of foreign material is part of the backdrop against which scientists interpret more subtle chemical traces that might point to past life.
What this “alien” rock tells us about the solar system
Viewed from a wider angle, Phippsaksla is a reminder that planets do not evolve in isolation. A detailed analysis on Nov 19, 2025 describes a Strange Rock Discovered on the Martian Surface May Be a Visitor From Outer Space and emphasizes that NASA’s Perseverance Rover has found an object whose journey from elsewhere in the solar system can shed light on how debris from asteroid belts and beyond has bombarded Mars over time and altered its crust. Each such meteorite is a physical sample of a different region of space, delivered free of charge to a planetary surface.
Other reports on Nov 19, 2025 underline the stakes, noting that There are moments in space exploration when a single picture forces scientists to pause, rethink and question everything, and arguing that NASA’s Perseverance rover has discovered a rock in the Jezero Crater region that may help reconstruct Mars’s impact history and past environmental changes through its composition. A complementary segment from the same outlet stresses that NASA spots weird rock on Mars that should not exist and suggests that studying such objects can refine models of the planet’s climate history and past environmental changes, since each impact can redistribute heat and materials across the surface in ways that leave lasting traces.
A rock that reframes Perseverance’s legacy
As the dust settles around Phippsaksla, the discovery is already being woven into a broader narrative about Perseverance’s impact on Mars science. A detailed feature on Nov 17, 2025 notes that NASA Discovered a Rock on Mars That Doesn’t Belong There and reminds readers that Using an onboard drill, Perseverance is the first rover to collect Martian rock samples with a miniature lab built into the rover in a Martian crater, a capability that will eventually allow scientists on Earth to compare meteorites like Phippsaksla with cores from ancient lakebeds once sample return missions proceed. That pairing could reveal how foreign metals and native sediments interacted over time.
Other outlets have leaned into the rock’s visual drama. A Nov 22, 2025 report describes how NASA’s Perseverance Mars rover recently came across an odd rock, dubbed “Phippsaksla,” that is unlike anything else the rover has seen and likens it to a “turtle-shaped” formation that looks totally alien to the Red Planet, reinforcing the sense that this object is an outlier in both form and substance within Jezero. A separate account on Nov 17, 2025 echoes that framing, stating that NASA’s Perseverance Mars rover recently came across an odd rock, dubbed “Phippsaksla,” that likely crashed on Mars instead of forming there, a concise summary of why this single boulder has quickly become a touchstone for discussions about how the planet is shaped by material from beyond its skies as much as from within.
