Abstract

Samples from the Rocknest aeolian deposit were heated to ~835°C under helium flow and evolved gases analyzed by Curiosity’s Sample Analysis at Mars instrument suite. H 2 O, SO 2 , CO 2 , and O 2 were the major gases released. Water abundance (1.5 to 3 weight percent) and release temperature suggest that H 2 O is bound within an amorphous component of the sample. Decomposition of fine-grained Fe or Mg carbonate is the likely source of much of the evolved CO 2 . Evolved O 2 is coincident with the release of Cl, suggesting that oxygen is produced from thermal decomposition of an oxychloride compound. Elevated δD values are consistent with recent atmospheric exchange. Carbon isotopes indicate multiple carbon sources in the fines. Several simple organic compounds were detected, but they are not definitively martian in origin.

  • Organic matter is absent on both Mars and moon although they do contain carbon.

    “However organic matter is absent on both Mars and moon although they do contain carbon [2]–[6].”

    From Can Plants Grow on Mars and the Moon: A Growth Experiment on Mars and Moon Soil Simulants (2014) · cites this paper as [6]

    The Organic Matter section (p. 1238937-5) reports carbon-bearing CO₂ in Martian fines and says Martian organic matter was not definitively detected. That does not establish that organic matter is absent from Mars; the same section says traces of Martian organic carbon cannot be ruled out. The paper does not address whether the Moon contains carbon or organic matter. (LLM, conf=0.88)

    Experimental — accuracy not yet measured

  • There is no organic matter on Mars, as far as we know.

    “There is no organic matter on Mars [2]–[6], as far as we now, so this would make the Mars simulant we used less suitable for experiments to investigate the potential of Mars soil, unless the experiment has as goal to test the potential of the soil after adding organic matter.”

    From Can Plants Grow on Mars and the Moon: A Growth Experiment on Mars and Moon Soil Simulants (2014) · cites this paper as [6]

    The Organic Matter conclusion (p. 1238937-5) says Martian organic matter was not definitively detected, which supports the narrower point that this analysis did not establish its presence. It does not support the categorical claim that there is no organic matter on Mars: the Organic Matter discussion says traces of Martian or exogenous organic carbon in the Rocknest sample cannot be ruled out. (LLM, conf=0.88)

    Experimental — accuracy not yet measured

  • Rocknest is the best-characterized martian soil to date.

    “Rocknest is the bestcharacterized martian soil to date (Bish et al., 2013; Blake et al., 2013; Leshin et al., 2013; Minitti et al., 2013; Archer et al., 2014; Sutter et al., 2017)”

    From Mars global simulant MGS-1: A Rocknest-based open standard for basaltic martian regolith simulants (2019) · cites this paper as Leshin et al., 2013

    The opening Rocknest sampling passage and the Isotopes section document extensive analyses of Rocknest fines, including mineralogy, volatiles, and isotopes. They support that Rocknest was well characterized, but the paper does not compare the extent of its characterization with all other Martian soils or establish the 'best-characterized to date' superlative.

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.
