Mystery Mars rock on is most likely an interstellar visitor | World | News
NASA scientists were left scratching their heads after the Perseverance Rover discovered a strange rock on Mars that apparently didn’t belong there; Its composition suggested a possible interstellar origin.
“This rock has been identified as an intriguing target,” NASA said in a recent blog post detailing the potential cosmic rock.
According to the post, the Perseverance Rover, which has been scanning the Red Planet for five years, encountered the geological oddity while exploring the Vernodden region of the 28-mile-wide Jezero Crater.
The interesting rock, christened “Phippsaksla,” was an impressive 31 inches wide.
While spotting a rock on Mars might not seem earth-shattering, this particular specimen stood out due to its “sculpted, towering appearance that stood out from the low, flat, and fragmented rocks around it.”
“Phippsaksla” creates a metallic effect
Further analysis by the Rover’s SuperCam revealed that the Martian pebble contained high levels of iron and nickel; this is a combination of elements more associated with “iron-nickel” meteorites than ordinary rocks.
Unlike their rocky counterparts, these metallic space rocks typically originate from the heart of large asteroids, as reported by Science Alert.
Forged in the early days of the Solar System, these unique rocks were formed when heavy minerals were embedded in heated rocks.
Interstellar origins?
The distinctive composition seemed to indicate that “Phippsaksla” did not originate from Mars, but instead was part of a meteor that crash-landed on the planet in the distant past.
Interestingly, although other iron-nickel meteorites have been discovered on Mars before – including the “Cocoa” meteorite detected in 2023 – this marks the first time Perseverance has encountered one of these interstellar rolling stones.
Uncovering the secrets of the Red Planet
Scientists will need to do more testing to confirm that the metal-rich stone is indeed a meteorite.
If interstellar origins are confirmed, the rock could provide invaluable insight into the history of the Red Planet.
This isn’t the only groundbreaking geological discovery the Perseverance Rover has made recently. Just last year, it uncovered speckled rocks that may offer some of the most convincing evidence yet of life on Mars.
