Mysterious Martian Rock with a Hole Baffles Scientists

NASA's Perseverance Mars rover has discovered a donut-shaped rock with a hole through the middle on the planet's surface, leaving scientists puzzled about its origins. Some experts believe it could be a meteorite that eroded over time, while others suggest it may be evidence of past rivers on Mars. However, one scientist argues that similar rocks in the area were likely brought in by floods. The team operating the rover has not announced plans to further investigate the rock, leaving its origins a mystery.
