Is The Life In Mars Possible In Future?

As for Mars, it is possible that scientists will one day find life on the Red Planet, and it will be a close relationship. But just because Mars is cold and unprotected doesn't mean scientists can rule out finding life there. Some have suggested that debris in the solar system is responsible for spawning life on Earth.

The Viking program in the 1970s was the first to provide data with evidence of life on Mars. The Mars meteorites did not prove that there was life on the planet, but they did not refute the possibility. Both Earth and Mars were frozen in their early history when the Sun was much fainter, but both showed flowing water, suggesting they would have had thick atmospheres to keep the surface warm.

Continued exploration of Mars and a growing understanding of how the planet has changed over the years have led many scientists to believe that Mars has all the ingredients for life: an abundance of water, an atmosphere as dense as Earth and a warm climate. If the atmosphere and water had been lost, life could have arrived on Mars. But billions of years later, life has not become more complex and it will take astrobiologists and geologists to find evidence of ancient microbial life on the surface of Mars.

The detection of liquid water on the surface of Mars has led scientists to question whether life could continue on the red planet even after it has moved so far away that conditions on the surface have become inhospitable. NASA's Curiosity Rover discovered evidence earlier this year of Mars-Gale Crater, an ancient salt lake on the planet's surface. This suggests the planet may have once supported microbial life.

In Europe, the Russian ExoMars Trace Gas Orbiter, launched in 2016, aims to detect atmospheric gases destined for active biological life on Mars. According to Parker, the European Space Agency is also working on exploring the ice on the Martian surface. NASA's rover has discovered methane on Mars, considered a simple organic molecule - a chemical clue to life.

On Mars, the Curiosity rover has discovered methane from vents on the planet that could be produced underground. However, according to ESA, the rover has found methane in parts of the surface, but not in the Martian atmosphere.

Although there are obvious and compelling indications of past and present life on Mars, there are also ambiguous points of favor and disfavor for life. Mars is a barren world, but it is also a world in which life could have flourished for quite a while before it reached a dead end, and if there were still life on it today, it could have been the seed of earthly life, or it could have been organisms on Earth that set out for it at the dawn of the space age. If we look at all the evidence we have learned about Mars, here are five ways to tell the story of life on the Red Planet.

Based on what we know about the evolution of life on Earth, it is highly likely that the life originated on Mars. If we can find life on Mars whose origins are independent of those on Earth and not of our long-lost microbial cousins, it leads us to believe that there are millions of planets and galaxies on which life has formed and big filters in the evolution timeline can be located.

If we find eukaryotic life on Mars, which is simpler than multicellular life (such as nematodes), this would mean that there was an evolutionary transition through the Great Filter. William Bain argues that life can arise in many ways, and that it can achieve this kind of transition in sufficient time, but that the rise of technological intelligence is rare, having happened only once in the Earth's 4.5 billion-year history.

NASA has not been able to ask direct questions about life on Mars since the Viking missions of the 1970s, but the assisted missions have been designed to find areas that hold promise for water and life and to investigate these areas on the ground for chemical and petrographic potential for existing fossil life. One of the main goals of the missions was to find traces of past life on Red Planet, and the rovers that have begun to travel into Jezero crater are working towards this goal. NASA has however focused on the search for life, with life being a prerequisite for water as the main driver of Mars exploration, and favors missions and experiments to support this goal.

In August 1996, a group of scientists announced that they found evidence of ancient life on Mars. Evidence included bacteria, molded objects and organic chemical molecules from the Mars meteorite ALH 84001, which originated in Antarctica. After confirming the past existence of liquid surface water, the Curiosity, Perseverance and Opportunity rovers began looking for evidence of past life, including a past biosphere based on autotrophic, chemotrophic and chemolithoautotrophic microorganisms and ancient water, including fluvial acoustic environments in plains related to ancient rivers and lakes that could have been habitable.

In 1965, Mariner 4 discovered that Mars has a global magnetic field that protects the planet from life-threatening cosmic rays and solar radiation, and observations by Mars Global Surveyor in the late 1990s confirmed this. Recent in situ data from the Curiosity robot suggest that the ionizing radiation from galactic cosmic rays (GCR) and solar particle events (SPEs) are not a limiting factor in assessing the habitability of today's surface life on Mars. Over the next few days, NASA presented evidence of ancient life on Mars at press conferences, President made statements on the subject on television and newspapers were full of reports, speculation and jokes about life on the Red Planet.

A meteorite discovered in Antarctica made headlines in 1996 when scientists claimed it contained traces of life on Mars. A further examination of the spherical structure, which is called egg-shaped, revealed that it may have been formed by processes of other life. Scientists have found that of the 34 Martian meteorites, three have the potential to be evidence of past life on the planet.
