According to NASA, if you want to find evidence of life on Mars, you’ll have to dig down to exactly 6 feet. Thanks to NASA’s experiments at the Goddard Space Flight Center in Greenbelt Maryland, scientists believe that amino acids now near the surface of Mars decompose much faster than previously thought. Amino acids are the basis of life. Life on the Organic Earth uses amino acids to make proteins and uses them to make enzymes that regulate chemical reactions and structures. Amino acids can exist without life, so we can’t prove that life exists on Mars, which is strong evidence, but Martian amino acids are exposed to cosmic radiation from the Sun. The traces that have been and destroyed them, and that they have ever existed. The Earth’s magnetic field and thick atmosphere protect amino acids and all life from cosmic rays emitted by the Sun. However, Mars currently has no magnetic field, and its atmosphere is thinner and more unstable than we are. But scientists don’t believe it has always been the case. Most scientists believe that Mars once had a thick atmosphere and magnetic field. It makes them believe that the red planet may have lived long ago, with evidence that the planet once had water on its surface. Mars rover currently looking for life on the planet can only dig a few inches below the surface. .. NASA scientists believe that it takes only 20 million years, geologically speaking, to erase evidence that the harmful rays of the sun penetrate the surface and the amino acids are present there. In fact, they presume that amino acids near the surface were previously present. It may have been completely destroyed by the sun’s cosmic rays over 100 million years ago. Although 100 million years may seem like a long time, scientists believe that billions of years have passed since Mars resembled a habitable planet. If scientists can dig quite deeply, they may be able to find some amino acids. Two meters, or just over six feet, is the distance they believe that if amino acids are present on Mars, they need to dig in to find them. Previously, scientists believed that amino acid evidence would last much longer, but took this new experimental amino acid and mixed them with soil intended to mimic Martian soil in test tubes. Then they blew it up with radiation equivalent to 80 million years of exposure on Mars. Previous experiments only blasted amino acids without soil simulation, which may have resulted in inaccurate estimates of their survival rates. Amino acids were previously discovered off-planet. Scientists have observed them in the atmosphere of the asteroids Rugu and Comet 67P. Amino acids are also found in meteorites that are thought to come from Mars, and scientists aren’t sure, but they don’t think they come from Mars and pollute the Earth. If NASA wants to find amino acids on Mars, it needs to send something that can dig deeper than the current rover.
