Appears to seem like it is two separate different types of rock/meteorite that have some how been bonded together!
Mars donut! Perseverance rover spots holey Red Planet rock
NASA's Perseverance Mars rover has rolled up on a rocky donut that may have fallen from the sky.
On Friday (June 23), Perseverance snapped a photo of a big, dark stone with a hole in its center. The intriguing rock is surrounded by others of a similar hue, suggesting a common origin — one that may extend beyond Mars.
The donut rock "could be a large meteorite alongside smaller pieces," representatives of the SETI (Search for Extraterrestrial Intelligence) Institute.
