NASA’s Perseverance Rover has found on the surface of planet Mars A strange rock formation that has left perplexed scientists. They have baptized it as ‘skull hill’ (‘La Colina de la Calavera’).
The finding was made on April 11 while the rover descended by a crest called Witch Hazel Hill. The rock was found in the Jézaro cratera huge old lacustrine bed 45 kilometers wide that has been the center of NASA’s operations on the red planet.
“It seems that it shouldn’t be there”says Margaret Deahn, a doctoral researcher at the University of Purdue (USA) who works with the Perseverance team. Deahn explains that, unlike his dusty environment, ‘Skull Hill’ is darker, more angular and is covered with small holes, which leads scientists to believe that he could have reached Mars from another place.
Using the high -tech supercam laser chamber of the Rover, the scientists analyzed a nearby rock with a similar composition and discarded The presence of space metal And therefore, that it is a meteorite.
It did not contain the characteristic indications of a space rock, as high levels of iron and nickel. Even so, NASA experts have not yet given a definitive answer.
An outstanding theory suggests that ‘Skull Hill’ could be a ‘floating’, a geological term for Rocks that have moved from their place of origin. This means that it could have been thrown to the Martian surface due to the impact of an old asteroid, dragged by erosion or even dragged by water currents billions of years ago.
“Fortunately for us, Rover has instruments that can measure chemical composition From the rocks on Mars, “says Deahn.
