EArceh may be home to the most glorious beaches in the solar system today, but 3 billion years ago, Mars may have claimed the crown. This is a conclusion New study In the facts of the National Academy of Sciences, based on the work of a Chinese and American team from the researchers working from the data collected by China Zhurong Mars Rover. When there is a beach, researchers suggest, perhaps there was life.
Everything has long been the stable science that Mars was previously home to abundant water. Its surface was sealed with ocean and sea ponds, and with the bottom of the old rivers, delta, and general fans. The water has not been long for a long time – the first 1.5 billion years of the planet, which is 4.5 billion years old. Early in its history, Mars lost its magnetic field, which allowed solar winds to rid most of its atmosphere; However, a lot of water was settled in space. In the water sites that disappeared that NASA Chinese National Space Administration They landed their Rover, and they studied not only ancient geology, but the possibility of signs of ancient biology. One like, Utopia PlantiaA great plain was chosen in the northern hemisphere of Mars, as a landing location in Zhurong, which fell on Mars on May 15, 2021. The northern low lands were believed to have been home to the oceans that covered up to a third of the surface of Mars.

Zhurong made some of its past in the Planitia past in Utopia with high -resolution cameras, which took pictures of the rocks that have a look of sedimentary objects. But it was the hesitant Rover Rover that brought back most of the journalist’s discoveries. Tool Creating penetration Up to 330 feet below the surface, but Chirong was almost this deep to hit Paydirt. Along the extension of 0.8 miles in Plantia Utopia, discovered 76 geological reflectors-or separate areas of rocks that wear seismic waves or radar to the surface. The reflectors are barely uncommon under the ground. They are what they do in the first place. But these reflectors were private.
For one reason, they were all inclined in the same direction, at an angle of six to 20 degrees. It also extends to depths between 30 to 115 feet. This made them look remarkably similar to depth and inclination of formations on the beach underground on Earth. The researchers cited the Bay of Bengal as a worldly analog of Mars’s reflectors, but they also confused them with 21 other beaches on Earth, which tend to have angles from four to 26 degrees.

“We find places on Mars, which seemed to be ancient beaches and the ancient river’s delse,” Benjamin Kardinas, a geology professor at Pennsylvania State University and a co -author of the paper, said in a statement accompanied by its issuance. “We have found evidence of wind and waves, and there is no shortage of sand-beach similar to holidays.”
It was not given that the angle reflectors were already formed by the ocean that disappeared. They could have been carved by wind, but researchers excluded this because there was a chaotic contrast in the corners along the extension of 0.8 miles, instead of the gradual slope that documented Zhurong. Rivers could have also been responsible, but the area studied by Zhurong was lacking in the valleys of the Telltale River that could have been left after the water was folded.

So, “The authors wrote,” We conclude that DIP reflectors under the ZHURONG landing site are the most consistent with those formed in a coastal environment. “
Can this coastal environment lead to life? The authors do not exclude it. “This has emerged for us immediately because it indicates the presence of waves, which means that there is a dynamic interface of air and water,” Cardinas said. “When we look back at the place where the first life evolved on Earth, it was in the interaction between the oceans and the earth, so this is to draw a picture of ancient home -based environments, capable of harboring friendly conditions towards microbial life.”
