Mars could have conditions conducive to the emergence of life and this is further evidence

Due to the fact that we have already sent several landers and rovers to Mars, and that several orbits are watching him, he is the planet we know most thoroughly in the universe, of course, except Earth. Still, no one can give a definite answer to the question, "Has there ever been life on Mars?"

Although the latest research does not allow definitive determination whether or not living organisms have appeared on Mars, their results provide further evidence that the Red Planet may have had conditions that would allow their development. These results recently featured in the journal Nature Communications.

The authors of this work, researchers from the Tokyo Institute of Technology, analyzed the readings taken in the Mars crater Gale by the rover Curiosity. The Gale Crater was formed a long time ago, more precisely, about 3.5 to 3.8 billion years ago, when a meteor hit Mars. Although today it is a dry wasteland, it once contained water. This water could even create a gigantic lake.

Analysis of the readings showed, among other things, two very important things. Firstly, that the water in the crater was salty, and secondly, that it had a relatively favorable pH of life. This indicates that Mars at least could have become home to living organisms. With the rest, there is other evidence for this. In 2018, NASA even revealed that it found organic particles on the Red Planet, which could have been formed through biological processes.

Of course, we will not be able to say that there was life on Mars until we find explicit confirmation, for example in the form of fossils. Another NASA rover will help in the search for such confirmation – Mars 2020 – which is to set off towards the Red Planet this year. The scale of research will increase even more as soon as the first people reach Mars. Nevertheless, who knows when we will really see the first manned mission that will be the goal.
