NASA rover finds traces of water on Mars rocks

New Delhi NASA’s Perseverance Rover has discovered important evidence on Mars, which clearly shows that the Red Planet once had a water-filled world. The discovery of rocks that may contain traces of life in Jezero Crater on Mars is important. Scientists believe that the surface of Mars was once filled with water. And these rocks are believed to have been replaced by water, leading them to believe that the Red Planet was actually a water world. The samples collected have been preserved by a robot and are being prepared for the journey to Earth. A report in Newsweek has given information about this.

The report said that NASA has specifically chosen the landing site of the Perseverance rover to reside in Jezero Crater. It is actually a 45 km wide crater located on the western edge of Isidis Planitia. It is located slightly north of the equator of Mars and is a flat plain. NASA wanted to investigate ancient lakes and rivers. It is about 2,300 miles (3,700 km) from the Curiosity rover’s landing site in Gale Crater. A study titled ‘Exactly Altered Igneous Rocks on the Floor of Jezero Crater, Mars’ has been published in the journal Science Advances. This discovery suggests that there are two different types of igneous rocks. Its discovery has surprised experts, who expected that sedimentary rocks could be found here.

I came upon the ancient lake of Jezero Crater expecting a lot of sedimentary rocks. I see them now in the old river delta, but the crater floor was a surprise: lots of volcanic rock.

Now my science team is sharing some of what they found together: https://t.co/HO0zRMue4h pic.twitter.com/z8ZOwqRPGG

These rocks contain sulfates and perchlorates, which were probably formed later by near-surface brine evaporation, the study said. According to NASA, it came as a surprise to scientists in the spring of 2021 when its Mars rover began examining rocks on the floor of Jezero Crater. The official handle of NASA’s Perseverance rover shared a post on Twitter with pictures of the rocks. It said I came across the ancient lake at Jezero Crater rather than a lot of sedimentary rocks. I see them now in the river delta, but it was a surprise.’
