A peculiar, white-colored rock seems weirdly out-of-place on the Purple Planet.

NASA’s Perseverance rover, which has been on Mars since February 2021, lately discovered a light-colored boulder on the floor of Mount Washburn, a hill inside Jezero Crater. Measuring 18 by 14 inches (45 by 35 centimeters), the rock is now named “Atoko Level,” as a result of it resembles, in shade, a equally named cliff inside Arizona’s Grand Canyon.
However whereas the earthbound characteristic is product of limestone, a sedimentary rock, Atoko Point on the Red Planet consists of pyroxene and feldspar, elements of igneous and metamorphic rocks. Researchers have provided two concepts about this one-of-a-kind discovery. Both the rock shaped elsewhere and was transported to Jezero Crater way back by a martian river, or it shaped underground and ultimately made its option to the floor.
The science group answerable for Perseverance’s exploits was trying ahead to finding out the wide range of rocks on Mount Washburn. Co-lead Brad Garczynski of Western Washington College says they signify a “seize bag of geologic items,” however that Atoko Level was the one which stood out.
Once I first noticed the picture of Atoko Level, I believed it resembled the light-colored interiors of a number of meteorites in my assortment. For instance, the inside of Camel Donga, which fell on the Nullarbor Plain in Western Australia, appears to be like eerily comparable. And, certainly, its foremost minerals are pyroxene and plagioclase, a sort of feldspar, the identical constituents that make up Atoko Level. Camel Donga is assessed as a eucrite, a sort of meteorite that may be a piece of the asteroid 4 Vesta.
