A peculiar, white-colored rock appears weirdly out-of-place on the Pink Planet.

NASA’s Perseverance rover, which has been on Mars since February 2021, these days found a light-colored boulder on the ground of Mount Washburn, a hill inside Jezero Crater. Measuring 18 by 14 inches (45 by 35 centimeters), the rock is now named “Atoko Degree,” because of it resembles, in shade, a equally named cliff inside Arizona’s Grand Canyon.
Nonetheless whereas the earthbound attribute is created from limestone, a sedimentary rock, Atoko Degree on the Pink Planet consists of pyroxene and feldspar, components of igneous and metamorphic rocks. Researchers have equipped two ideas about this one-of-a-kind discovery. Each the rock formed elsewhere and was transported to Jezero Crater approach again by a martian river, or it formed underground and in the end made its methodology to the ground.
The science crew in charge of Perseverance’s exploits was attempting forward to discovering out the wide selection of rocks on Mount Washburn. Co-lead Brad Garczynski of Western Washington Faculty says they signify a “seize bag of geologic presents,” nonetheless that Atoko Degree was the one which stood out.
After I first seen the image of Atoko Degree, I believed it resembled the light-colored interiors of plenty of meteorites in my assortment. As an illustration, the within of Camel Donga, which fell on the Nullarbor Plain in Western Australia, seems eerily comparable. And, actually, its main minerals are pyroxene and plagioclase, a type of feldspar, the an identical constituents that make up Atoko Degree. Camel Donga is assessed as a eucrite, a type of meteorite that may very well be a chunk of the asteroid 4 Vesta.
