Possible Surface Reactions on Mars: Implications for Viking Biology Results
Abstract
The results of two of the three biology experiments carried out on the Viking Mars landers have been simulated. The mixture of organic compounds labeled with carbon-14 used on Mars released carbon dioxide containing carbon-14 when reacted with a simulated martian surface and atmosphere exposed to ultraviolet light (labeled release experiment). Oxygen was released when metal peroxides or superoxides were treated with water (gas exchange experiment). The simulations suggest that the results of these two Viking experiments can be explained on the basis of reactions of the martian surface and atmosphere.

The Viking labeled release experiment yielded results consistent with biological activity: 14C-labeled gas was produced from surface samples, but not when they had been sterilized by heating to 160°C.
“Curiously, the labeled release experiment did indeed yield results consistent with biological activity: 14C-labeled gas was produced from the surface samples, but not when they had been sterilized by heating to 160°C (the negative control).”

“Interpretation of these contradictory results has been a matter of debate for over three decades (Klein et al., 1976; Klein, 1977, 1979; Ponnamperuma et al., 1977; Owen, 1979; Navarro-González et al., 2006, 2010; Biemann, 2007).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
