A recent paper by Navarro-Gonzalez et al. [Navarro-Gonzalez R, Navarro KF, de la Rosa J, Iniguez E, Molina P, Miranda LD, Morales P, Cienfuegos E, Coll P, Raulin F, et al. (2006) Proc Natl Acad Sci USA 103:16089-16094] claims to show that the Viking GCMS (gas chromatograph-mass spectrometer) experiment, which carried out a search for organic matter at the surface of Mars in 1976, "may have been blind to low levels of organics." To rebut this assertion, the Viking experiment, test data, and results on Mars are reviewed, and the fallacies in the design, execution, and interpretation of the new experiments presented by Navarro-Gonzalez et al. are critically examined.
纳瓦罗 - 冈萨雷斯等人近期发表的一篇论文[纳瓦罗 - 冈萨雷斯R,纳瓦罗KF,德拉罗萨J,伊尼格斯E,莫利纳P,米兰达LD,莫拉莱斯P,西恩富戈斯E,科尔P,劳兰F等(2006年)《美国国家科学院院刊》103:16089 - 16094]声称表明,1976年在火星表面进行有机物搜索的海盗号气相色谱 - 质谱仪(GCMS)实验“可能对低含量有机物视而不见”。为反驳这一断言,本文回顾了海盗号实验、测试数据以及在火星上的结果,并对纳瓦罗 - 冈萨雷斯等人所展示新实验在设计、实施和解读方面的谬误进行了批判性审视。
