Perseverance Rover Discovers Mysterious Rock on Mars
Full Transcript
NASA's Perseverance rover has identified a peculiar shiny rock on the Martian surface, which scientists speculate could be a meteorite originating from an ancient asteroid. This rock, nicknamed 'Phippsaksla', was noted for its distinctiveness against the flat, broken terrain surrounding it, prompting a closer examination.
According to a recent blog post on the rover's mission page, tests indicated high levels of iron and nickel, elements commonly found in meteorites that have impacted both Mars and Earth. While previous Mars rovers like Curiosity, Opportunity, and Spirit have documented metallic rocks, this is potentially the first metallic rock identified by Perseverance, highlighting the rover's ongoing exploration success.
NASA's report states that Phippsaksla is located just beyond the rim of a crater, resting on ancient impact-formed bedrock, which could provide insights into both its formation and its journey to its current location.
The rover's SuperCam instrument, which is capable of firing a laser to analyze the chemical composition from several meters away, was directed at the rock, revealing its unusual metallic makeup. This discovery is significant because iron and nickel are typically associated with meteorites formed in the cores of ancient asteroids, not with normal Martian rocks.
If confirmed as a meteorite, Phippsaksla would join a lineup of notable meteorite finds recorded by earlier missions, including Curiosity's notable samples 'Lebanon' and 'Cacao', as well as fragments noted by Opportunity and Spirit.
Each of these findings has contributed to a deeper understanding of how meteorites interact with the Martian surface over time. The location of Phippsaksla outside Jezero crater could also yield clues about its formation and the processes that transported it to its current site.
NASA's team continues to investigate the rock's composition to confirm its extraterrestrial origins. If the evidence supports a meteorite classification, it would represent a milestone for the Perseverance mission, reinforcing that the Martian surface still holds surprises for scientists.
Perseverance, which launched from Cape Canaveral Space Station on July 30, 2020, and touched down in Jezero crater on February 18, 2021, has been on a four-year mission to search for signs of ancient microbial life and explore the Martian landscape.
Built at NASA's Jet Propulsion Laboratory and costing approximately two point seven billion dollars, Perseverance is equipped with advanced scientific instruments, including a seven-foot robotic arm and a rock drill for sample collection, supporting future human exploration goals for the 2030s.
