The planet Mars has become the center of attention in the context of human space exploration. There are two things that give the red planet: if there is life there, and if Mars could be colonized by humans, if later in the Earth can not sustain life.
But the latest research by scientists of both intelligent world-class universities, MIT and Harvard was more advanced and revolutionary. You want to prove the feasibility of the tree of life on Earth has its roots in March. The researchers also created a tool to prove the allegations.
The device is called the Search for Extra-Terrestrial Genomes, or SETG. The tools are under development, examining samples of Martian dust, to isolate the genetic material, which can occur - in the form of insects or other living creatures, who died a few million years ago.
This tool, researchers can use the normal biochemical techniques to analyze the result of genetic sequences and compare the results of the earth.
"This is a long term project," said the researchers at MIT, Chris Carr has published Space.com. "Jikan later, we found no link with the Earth, the Earth may be a creature from Mars. Or, vice versa, and sent from Earth to Mars."
The idea that living organisms on Earth came from Mars might not be on everyone's mind. However, this is not a crazy idea.
For although this time the surface of Mars a cold, dry and free of all life - There is ample evidence that the planet was warmer and wetter billions of years ago.
As on Earth, when life depends on water. Ancient Mars may have been a supporter of a type of life - perhaps even before the Earth. Similarly, the researchers said.
If this happens, Martian microbes may have mengkolonialisasi Earth when a giant asteroid glide to Mars and make the particles splash and then travel experience between spaces. Researchers estimate that one billion tons of Martian rocks that have traveled in recent years.
And microbes are very strong, so it may be that some of them could have survived the impact of asteroids, and to a new home on another planet. Adding to the car, the orbital dynamics of the show is 100 times easier to Mars rocks to Earth and not vice versa.
However, Carr said, is less likely to find something on the surface of Mars. Ways you can do is dig. "There are two possibilities, Mars has life or not. But we want to be sure."
Meanwhile, the U.S. space agency has no opinion seoptimis researchers. "It is not plausible that life on Mars associated with life on Earth - and called on the two planets from genetics," says astrobiologist from the Ames Research Center of NASA in Moffett Field, California Chris McKay. But "in all cases, it will be important to test this hypothesis."
