"Phoenix" was a period of 3 months exploration mission, cost $ 420,000,000 .. .World Scientific reports </ P> <P> before the formal start of work, "Phoenix" was the implementation of the two digging exercise - a spade shovel to dig up Martian soil, then dumping, as the official preparation for mining exploration. .Did not think that scientists from the excavation so that it exercises very interested in harvesting the unexpected discovery: in the two exercises, the soft soil of Mars with gleaming white piece of material mixed together, scientists believe that either of these white matter .surface ice, either salt deposits. .</ P> <P> "Phoenix" was excavated area on the right side of the exercise carried out investigations at three locations, the scientists under the fairy tale "Goldilocks" to their name from the three nicely - "Baby Bear", " .Mama Bear, "" Papa Bear. " .In the first dig, scientists command "Phoenix" at an angle to the "Baby Bear" mining, digging in the permafrost of about three tenths of a deep-inch hole, shovel the soil into the arm where. .</ P> <P> search for life there are three elements </ P> <P> arm, according to NASA's Jet Propulsion Laboratory engineer 阿什蒂特雷 ratio - Ao Lunnu (Ashitey Trebi-Ollennu), the " .Phoenix "will be the swing arm 90 degrees, while awaiting further instructions to the dumping of a shovel of soil micro-oven. .Oven and then heated soil samples, analysis of steam, looking for traces of organic compounds. .Although the oven door does not spring fully open as scientists, as expected, but Smith said that this is not a problem. .In the next few days, "Phoenix" will take place from the other two sites excavated soil of Mars, through the microscope and its chemical laboratory for analysis. .</ P> <P> "Phoenix" can not detect fossils or living microbes, on the contrary, it further with a shovel of soil and ice to study whether liquid water ever existed on this, here the existence of organic compounds. .Organic compounds containing carbon atoms and hydrogen atoms. .Scientists generally believe that liquid water, organic matter, heat is a necessary environment for life for the three conditions. .</ P> <P> 2004 years has been roaming the Martian equatorial regions near the twin probe "Opportunity" and "Spirit" and found the water was at or near the surface of Mars from the ancient flow of the evidence. .Earlier this week, Smith said: "We will be taken in this exploratory step. Our scientific instruments are not used to decipher the DNA molecule password, we will find life can thrive in this environment, the basic elements of .. "World Scientific reports </ P> </ p>.
