Mars is one of the most fascinating planets among all the other planets in our solar system, mainly because it is very similar to Earth. For centuries, scientists have speculated about whether or not there is the possibility of life beyond planet Earth. After the discovery of water particles in the form of ice on Mars, the theory about the probability of life on the planet is now considered possible because, according to scientists; Mars had a warmer, more habitable environment about a few billion years ago, as can be seen from the planet's various canyons. Mars is of particular interest for studying the origins of life due to its striking resemblance to Earth. The seasons on Mars are also quite similar to those on Earth but, however, they are twice as long as those on Earth. It would be possible to create human-scale living conditions there. Furthermore, scientists have found that the current atmosphere of Mars resembles Earth's atmosphere a billion years ago. They hypothesize that the process that warmed Earth's atmosphere to allow plants and animals to exist could be repeated on Mars. Furthermore, Earth and Mars share the fundamental elements necessary for the existence of life (carbon, oxygen and nitrogen), albeit in different quantities. For example, the Martian day has a duration very close to that of the Earth; a solar day on the Red Planet lasts approximately 24 hours, 39 minutes and 35.44 seconds (that of Mars). In order for humans to survive on the Red Planet, some basic conditions would have to be met, such as water and oxygen, which are not easily available. The air on Mars is mainly composed of carbon dioxide which accounts for about 95%, followed by nitrogen which accounts for about 3% and other gases including oxygen which is less than 0.4%. Also, the…half of the card…is considered, as the technology to start a civilization is available but at a certain cost. The question of whether life exists on Mars has fascinated humanity for a long time, even before the first mapping of the red planet in 1877. And it seems that today we are no closer to a definitive answer. While authors, scientists, astronomers, and even Hollywood have long grappled with this question, each proposing a form of life on Mars that ranges from the scientifically probable to the science fiction imaginary, they have continued to explore Mars in the ever-growing quest to find life tests. There. To date, Martian soil samples have only suggested chemical, but not biological, activity. It appears that the closest answer to life on Mars is that there may be dormant bacteria there, perhaps in regions of Mars' icy polar caps..
