Signs of life on Mars

The two halves are completely different. This hurts scientists for years. The northern hemisphere of the red planet is a low and flat plateau, which is one of the most flat surfaces of all the Solar System planets. Some theories suggest that water used to exist in the Northern hemisphere, so the surface is smooth and flat. Meanwhile, the southern hemisphere's surface is convex, broken, and has an average height of 4- 8km compared to the northern hemisphere. Scientists believe that the hemisphere may have suffered a devastating meteorite on a large scale. (Photo: Fineline)

Methane on Mars. In 2003, the European Space Agency's "Mars Express" self-propelled robot discovered methane on Mars. Scientists estimate that methane has existed on Mars for about 300 years, but no one can explain how and which creature has produced methane here (usually, methane is mainly due to animals produced).

Water on Mars. Although there is a lot of evidence that there was water on the ancient Mars, there is still a mystery. The atmospheric pressure on Mars is only 1% of the earth's, so the ability of water to remain on the surface of Mars is very low. But the grooves on Mars have always been seen as evidence of running water at least once a year. (Photo: Fineline)

Mars used to have a vast ocean. Most Mars remote senses have a duplicate result - on Mars there are many signs that there used to be oceans, rivers and canals, rich and complex. Studies suggest that Mars previously had a warmer temperature and had water, a condition for life. (Photo: Fineline)

Is there life on Mars? The surface of Mars has favorable conditions for life. Even on earth, living creatures live in more extreme conditions, such as in the Arctic or the barren Atacama desert in Chile. On earth, wherever there is water there is life there. Thus, if water exists on Mars in liquid form, then the red planet is fully capable of living organisms. (Photo: Fineline)

Life on Earth originates from Mars. Scientists found a meteorite in Antarctica coming from Mars. This meteorite piece was thrown out of Mars when the red planet collided with the comet. On the surface of meteorites there are also signs that bacteria live. Therefore, many scientists claim that the origin of life on Earth probably originates from this Martian meteorite.

Should humans migrate to Mars? To determine if we can live on Mars, we need to fly to the place to verify the reality. As early as 1969, NASA had planned to land at Mars in 1981, until 1988 to build a research station there. So far that plan has not been realized because there are so many difficulties. However, maybe one day, humanity will go to Mars and maybe live on it. (Photo: Fineline)
