    A Historical Account of the Origin, Evolution, and Demise of NASA’s Oxymoronic “Astrobiology”/ The “Arsenic Monster” of Mono Lake/ and a Modest Proposal to Educate Dabblers in Microbiology Research
    (2012-01-30) Gest, Howard
    This essay presents a select Time Line for early speculations on “extraterrestrial life” and attempts to obtain experimental evidence for past or present life on the Moon and Mars. To date, there is no credible evidence for “life elsewhere,” even the simplest forms (microbes). Nevertheless, NASA continues to trumpet “astrobiology,” an oxymoron that suggests or implies that life has actually been found beyond Earth. NASA exploits the fallacious notion that the existence of terrestrial bacteria able to live under “extreme” chemical or physical conditions (“extremophiles”) provides evidence for “astrobiology.” In December 2010, NASA announced, in a massive publicity event, that their grantees isolated a bacterium from sediment mud of Mono Lake (CA) that defies basic biochemical principles of all known forms of life on Earth in that arsenic replaces phosphorus in its DNA and other P–containing essential metabolites. The so-called evidence for the “Arsenic Monster” [a presumed harbinger for “astrobiology”] has been strongly criticized and is being rigorously tested by independent investigators. These include Rosie Redfield and her collaborators who hope to submit their work to Science in early 2012.

    On the Origin. Evolution, and Demise of an Oxymoron: “astrobiology.”

The so-called evidence for the “Arsenic Monster” [a presumed harbinger for “astrobiology”] has been strongly criticized and will soon be rigorously tested by independent investigators.
