In April, the MRO (Mars Reconnaissance Orbiter) discovered an impact crater, which earned astronomers’ attention. Astronomers estimate that the impact happened between February 18th 2017 and March 20th 2019. The crater looks nothing like the circular depression we all are used to see on different planets; it is an artwork in itself.
In contrast with Mars’ reddish aspect, the crater exhibits hues of black and blue. What is more amazing is its proportion and the impact waves that resulted.
WHAT CREATED THIS CRATER?
While Mars is covered in impact craters from the hundreds of asteroids and comets that fall on its surface every year, some of them creating some impressive craters, according to Dr. Veronica Bray, planetary scientist and spacecraft operations engineer at the University of Arizona, the outcome of the impact is remarkable.
The space rock that hit Mars was quite small, approximately 1.5 meters wide (5 feet), but the mark that it left on the surface of the Red Planet is exceptional, about 16 meters wide (around 50 feet). A rock that small usually burns down in Earth’s atmosphere or in Mars’. But this one was unusual in the sense that it must have had a dense physical composition that made it possible to hit the surface of Mars without shattering and to create such a big impact crater.
The impact dispelled the reddish dust of Mars in order to reveal a coal-black rocky mantle and blue ice that was until now hidden. The space scientist believe that the cruts is most likely basalt.
