Mysterious doughnut-shaped rock spotted on red planet by the Mars Perseverance Rover
This fascinating find adds to the ongoing mission of the rover, which aims to uncover ancient signs of microbial life in the vast expanse of Mars.
According to SETI, the rock could potentially be a “large meteorite alongside smaller pieces,” but the Perseverance team has not made any attempts to examine it up close. But the rock’s true origins remains shrouded in mystery.
Jim Rice, an assistant research scientist at Arizona State University’s School of Earth and Space Exploration, was the first to spot the doughnut-shaped rock on June 14. While Rice cannot completely rule out the possibility of it being a meteorite, he deems it highly unlikely based on the characteristics of the region.
Rice explains that the area where the rock was found is known for housing rocks with hollowed-out interiors. These sedimentary sandstones, estimated to be billions of years old, were likely transported by floods through the Neretva Vallis, a significant river channel responsible for depositing water, rocks, and sediment in the vicinity.
The scientist speculates that the wind may have played a role in gradually enlarging any pre-existing pits or cavities in the rock. Alternatively, the rock could have had a weaker center. Ultimately, from a scientific standpoint, the doughnut-shaped rock does not appear to possess any extraordinary features.
The Perseverance rover continues its tireless quest to unveil the secrets hidden within the Martian terrain, inching us closer to understanding the mysteries of our neighboring planet and the possibility of extraterrestrial life.
