Scientists plan to send bacterial life on Mars, interplanetary flight test conducted.

Meteorite impact on Mars, Mars debris scattered in space, forms of life on Mars with debris scattered to the earth. These similar bacteria .life forms slowly evolved into animals and humans. "Planetary Society funded the cost of $ 1,000,000 of life interstellar flight. .</ P> <P> Although the simple life forms in outer space without additional protection to survive the views of highly controversial, but scientists have found bacteria on Earth many previously thought to be impossible to survive extreme environments, such as hot .boiling acid hot springs, ocean depths of nuclear reactors and so on. .But the air for the bacteria can survive for several years in deep study is the first time. .</ P> <P> In fact, Russia does not automatically end the spacecraft landed on Mars, but in its larger satellite, Phobos on the landing. .Ship called the Russian Phobos spacecraft will fly the soil 10 months arrived in Mars orbit, and orbit around Mars for several months, eventually landing in Phobos. .The Phobos spacecraft will collect soil samples, with the life of the spacecraft back to Earth with interstellar flight JEM. .Those collected from the soil of Phobos is expected to be retrieved from the soil from the moon after the man first planet from the outside to retrieve soil samples. .</ P> <P> based in Pasadena, California, United States Planetary Society on Russian spacecraft to Mars and back to Earth, to reach deep space is very interesting. .Bruce - Bates said, "in low Earth orbit by the Earth's magnetic field of biological protection, the Earth magnetic field to the cosmic rays and the most intense solar radiation reflected away. Therefore, on the international space station or spacecraft, or other bacteria can not test .Biology can survive in interstellar space as they orbit a few hundred kilometers high. However, the biological taken to Mars and return, we find that the experimental samples in deep space could survive the intense radiation environment. "</ P> .Soil <P> Russian spacecraft Phobos mission will last 34 months, will be equipped with the Earth in a bio-3-inch diameter titanium metal boxes. .These will withstand the severe test of the Earth organisms, including Deinococcus radiodurans, can withstand intense radiation derived from its Ming Kenan bacteria. .Other organisms, including Arabidopsis thaliana. .Arabidopsis quite amazing, it does not get DNA from their parents genes, but their parents come out of thin air do not have the gene. .There can tolerate extremes of temperature and pressure bears insects, brewing beer yeast, and the polar regions from Siberia permafrost soil samples obtained. .The soil samples contain many different micro-organisms, scientists can be an interdependent biological community it can be more than a single species, stronger, more resistant to radiation research. .Scientists say that life is very strong interstellar flight JEM, lost targets if the spacecraft crashed into Mars, Life Star Flight Experiment Module will not be damaged. .</ P> </ p>.
