NASA's Perseverance rover recently identified a peculiar rock formation named Phippsaksla during its ongoing exploration of the Jezero Crater region on Mars. Located at Vernodden, this sizable boulder measures approximately 80 cm and was photographed using the Left Mastcam Z camera on September 19, 2025. Unlike the common low-lying and fragmented rocks typically found in the area, Phippsaksla's distinct shape and size have intrigued scientists, prompting further analysis and discussion within the scientific community, highlighted in NASA's blog post titled 'A Stranger in Our Midst.'

The rock's unusual appearance has raised questions about its origin. Its distinctive form sharply contrasts with the native Martian crust, leading scientists to investigate the geological history of this formation. Initial analysis using the SuperCam laser revealed significant concentrations of iron and nickel within the boulder. These elements are commonly associated with iron-nickel meteorites that typically originate from large asteroid cores. This discovery raises intriguing possibilities regarding the rock's potential extraterrestrial roots.

Measuring roughly 31 inches, Phippsaksla resembles the size of a small desk, further accentuating its solitary position amid the Martian terrain. Scientists are now exploring the hypothesis that this rock could be a long-lost meteorite that impacted Mars in the distant past. Given its metallic signature, the inquiry into its history is of paramount importance.

Researchers are also considering why Perseverance discovered this potential meteorite outside Jezero Crater, rather than within its bounds. The boulder is situated atop bedrock likely formed by previous impact events, indicating that it may have been preserved from extensive geological activity for an extended period. Ongoing investigations will be essential to unravel the origins of Phippsaksla and its significance in understanding Martian geology and solar system history.
