NASA spacecraft discovered traces of water on Mars, evidence of rivers in pictures

A spacecraft of the US space agency NASA has sent evidence of water on Mars. After analyzing it, scientists have told that water used to flow on the surface of Mars 2 billion years ago. Salt Minerals on Mars, which came with this water, are still present in the way of its flow. NASA's Mars Reconnaissance Orbiter has also sent pictures of minerals present in the path of water flow on the surface of Mars. Scientists believe that millions of years ago there was a huge reservoir of rivers and ponds on Mars. Scientists at the Caltech Institute said that the presence of water on Mars raises the possibility of microbial life. As the atmosphere of Mars became thinner over time, the water present there evaporated away. Due to this Mars turned into a desert. NASA's Mars Reconnaissance Orbiter (MRO) is trying to understand this atmosphere of Mars. It is generally believed that the water of Mars evaporated about 3 billion years ago. But, two scientists studying data collected via MRO on Mars over the past 15 years have found evidence that significantly shortens that timeline. His research showed that liquid water existed on Mars between 2 and 2.5 billion years ago. This shows a difference of about a billion years compared to previous estimates. Research published in AGU Advances on December 27, 2021 states that chloride salt has been found in the flow path after water evaporated from Mars. The shape of some of the basins on Mars indicate that water once flowed on this planet. Solid salt found on Mars has become the first mineral evidence to confirm the presence of liquid water. Elon Musk, the world's richest man, wants to establish a human city on Mars. Musk has predicted that his company SpaceX will be able to take humans to Mars within the next 10 years. Musk recently made this bold claim on the Lex Friedman podcast. Musk reiterated his idea and said that humanity should become a 'multi-planet species'.
