It s critical to detect life on Mars before humans set foot on the red planet

Viking landers touched down on opposite sides of Mars in 1976 and carried out experiments in which soil samples were fed liquid nutrients and incubated. Instruments looked for gasses such as oxygen that would be given off by biological activity metabolizing those nutrients.  This illustration shows NASA’s Mars spacecraft carrying the Perseverance rover as it approaches the Red Planet. Hundreds of critical events had to be executed perfectly and exactly on time for the rover to land on Mars safely on Thursday.(NASA/JPL-Caltech) Those experiments detected traces of gases, which had the biologists very excited. But another experiment on the same mission searched for organic molecules in the soil and failed to find any. No organics means no life, so the conclusion was that the gasses released in the biology experiments were not a sign of life, but the result of ordinary non-biological chemical reactions.

10 Crazy Theories And Conspiracies Regarding Mars Human beings have been fascinated by Mars since antiquity. Now, we’re working toward landing on it. However, conspiracy theorists and fringe thinkers will tell you that we’ve already been to Mars, at the very least. These crazy-sounding but interesting stories won’t go away until we finally set foot on the red planet. In the meantime, here are 10 “out of this world” theories about our celestial next-door neighbor. 10 Is Phobos Really A Space Station? When the European Space Agency stated that one of Mars’s moons, Phobos, appeared to be hollow, it mirrored the findings of Russian astrophysicist Dr. Iosif Shklovsky from the late 1960s. Not only did Shklovsky believe that Phobos was hollow, but taking its unusual and uneven orbit into account, he believed there was a real possibility that it was artificial.
