| r is the big surprise from the Vikings." But 30 years we looked at the puzzle pieces missing. Phoenix provides a missing piece: perchlorate. Perchlorate found on Mars Phoenix is one of the most important since the Viking results. "Perchlorate, an ion, chlorine and oxygen, a strong oxidizer when heated. It can sit there with the surrounding soil on Mars billions of years of organic matter does not break them, but when the heat check the soil organic matter, Perchlorate destruction of their rapid, McKay said.
This interpretation Navarro Gonzalez and his four co-presented the challenge of organic compounds on Mars Viking experiments without their detection limit of the sample in the interpretation of the Viking scientists. In contrast, Viking scientists were interpreted as contaminants chlorine compounds. Mars from Mars and further work on the meteorite is about to visit is expected to help solve this problem. NASA's Mars Science Laboratory mission in 2012 to provide the curiosity probes to Mars in the Mars (SAM) instrument by NASA Goddard Space Flight Center Greenbelt, Moss samples carried the contrary, the Viking, and Phoenix curiosity to stray, and therefore analyze more rocks, and examples. SAM can check the organic matter in the Martian soil and rock powder, baking Viking higher than the temperature of the sample needed and by using another liquid extraction method in many low temperature. Combining these methods in a series of sample programs to further test the hypothesis that the oxidation of the new report may have been fierce in the Viking sample organic acid is destroyed. Vikings organic chlorine was found to be interpreted as contaminants from the Earth one of the reasons is that they are two isotopes of chlorine in the ratio of these isotopes on Earth matched three to one ratio. They do not know the ratio of Mars to determine yet. If there is different than the earth, will support the interpretation of the seventies. If the organic compound |
