Martian soil poison found there may be adverse to life
-- August 6, according to NASA's Space Network, NASA's "Phoenix" Mars landers have the latest data shows that the original come to the conclusion different from the surface of Mars Arctic may not be conducive to life there. In July this year, "Phoenix", the microscopic, chemical and electronic transmission of the two soil samples for analysis found that Martian soil may contain a toxic substance perchlorate, which is a strong oxides, create A not conducive to any potential life of the poor environmental conditions. This new discovery and microscopic, chemical and electronic transmission of the first analysis for different results, the first analysis showed that the soil of Mars and the Earth in several areas the same soil, including its mineral content and pH, and Similar to the Earth. "Phoenix" mission chief researcher Peter Smith said: "microscopic, electronic and chemical analysis instrument of transduction initial analysis showed that the soil of Mars similar to Earth's soil. But further analysis showed that the Martian soil is different from some of the cost of the Earth." 8 1, It is reported that the microscopic, chemical and electronic transmission of the instrument on Mars have found evidence of water, the relevant departments and even to the White House report Mars has water, or even life may have existed. But in an interview, Smith denied any submission to the White House briefing. Smith pointed out that at present these conclusions can not be fully determined, he said: "We abide by strict scientific procedures, although we have not completed all the work of soil samples, but we have a very interesting results." NASA On the 5th will hold a press conference for further discussion microscopic, chemical and electronic transmission of these new-found. Prior to this, "Phoenix" task group has been waiting for from the "Phoenix", the advanced thermal and gas analyzer information to check if the equipment found in the Martian soil samples perchlorate. And advanced thermal gas analyzer in the micro-oven baked Martian soil samples analyzed from the soil by water vapor in the volatile, to determine the soil composition. 3, and advanced thermal gas analyzer to directly from the ice at the top of the soil samples for testing found no perchlorate. Smith said: "This conclusion is surprising, since the advanced thermal and gas analyzer on the soil surface material of the early measurements contain perchlorate." Now, the research team is working to remove perchlorate pollution is the possibility of Earth material Sexual. "Phoenix" Task Force project manager巴里格尔德斯坦said: "The discovery of this astonishing conclusion, we can only recall the past, to exclude pollution of our planet Mars soil pollutants the possibility." Microscopic, chemical and electronic transmission of the wet-chemical laboratory will be Martian soil samples from the earth and the water mixed together. Beaker inner surface of the sensor plays a similar "electronic tongue", "taste" of soil to inspect possible into the salt water. These sensors can detect the pH of the soil surface. All of these data allow scientists to understand the Martian soil surface of Mars and the general picture of the past are suitable for life exist. Microscopic, chemical and electronic transmission of the first-analysis shows that the Star-weathered several life contains the necessary soluble minerals, including potassium, magnesium and chloride. With alkaline soil surface, the soil on earth for the growth of certain plants, such as asparagus.
