When talking about places where extraterrestrial life could potentially exist, few objects are so much spark the imagination as one of the closest neighbors of the Earth. For centuries man has looked to Mars and considered it a home for other creatures. Over the past 50 years various missions on the red planet trying to determine the possibility of this evolution. But how likely is life on Mars?

Living environment

Today the planet is dry and barren, most of the water is hidden in the polar ice caps. The thin atmosphere allows radiation from the Sun to irradiate the surface, which gives a test for possible life. Evidence of the existence of water came in 2000 when pictures of the station “Mars global surveyor” has shown the ditch, which, apparently, formed over flowing water.

According to one estimate, an ancient ocean covered 19% of the planet’s surface. Perhaps liquid water and is now flowing on Mars or on the surface or under it. Most of the disputes focused on the recurring lines on the slopes, which could create water or quicksand.

Water beneath the surface may be more favorable for life. Underground water protects life forms from harsh radiation. There is evidence of ice deposits the size of lake superior.

Tiny UFO

Over the past 4 billion years Earth was visited by many “aliens” from Mars. Our planet was bombarded stones, related with the surface of the red planet. With 34 three Martian meteorites contain evidence of the existence of life on Mars.

Meteorite found in Antarctica, became a sensation in 1996 when scientists announced that it may contain evidence for traces of life on Mars. Known as ALH 84001, a Martian rock contained formation, similar to the fossilized remains bacterostatic life forms. However, these organic molecules were formed not in biology, but because of the volcanism.

Despite its geological origin, organic nature of the molecules, the positive moment in the hunt for life.

The researchers also found structures resembling petrified of nanobacteria, meteorite international bridge from Mars that fell in Egypt. The researchers found that three quarters of organic matter in the meteorite could not occur because of contamination with organics on Earth. However, further study of spherical structure called ovoid, showed that it likely formed during the processes other than vital.

The third meteorite, Shergotty contains elements that suggest the presence Bopanna residues and microbial communities.

But a fresh review of the surface will help to understand the evolution of life on Mars even better. The spacecraft found evidence of water under the Martian crust, the hot springs, which are considered an excellent medium for the development of life, and irregular liquid precipitation. While the Rover “Curiosity” — not a mission to search for life, there is hope that he will be able to point out the place that the first settlers will study and analyze.

Maybe we are the Martians?

Transport material from Mars to Earth and probably ago sparked debate about the possibility of entering life on the planet. The essence of the dispute was the tiny organisms are resilient enough to survive the journey through the cold, airless, radiation-filled vacuum of and bring life to your new home.

The idea of such “seeding” is not limited to the interaction with Mars. Some have suggested that the rocks of the outer Solar system to bring life on the Earth.

“If we find life on another planet, will it really the other will be connected with us? And if so, did she give birth to us, or we gave birth to it? — asks the researcher Dina Pasini from the University of Kent (UK). We can’t answer these questions right now, but they are not so far fetched as you assume.”
