Provenance Record

Misattribution to NASA: 'Glen Torridon region of Gale crater' / 'clay-rich mudstone' — NASA snapshot does not contain these terms

The article says 'a clay-rich mudstone in the Glen Torridon region of Gale crater, an area that ancient lakes and streams once filled, [according to NASA]'. The NASA snapshot makes ZERO mention of 'Glen Torridon', 'Gale crater', or 'mudstone' — it locates the sample only on 'Mount Sharp' and uses 'clay-bearing rocks' / 'clay-enriched region'. Glen Torridon and the mudstone framing ARE in phys.org and CNN snapshots; re-attribute to those sources or remove the specific terms when citing NASA.

Misattribution to JPL: 'first use of TMAH thermochemolysis on another planet' — the word 'thermochemolysis' is not in the JPL snapshot

JPL says 'The Mary Anning 3 sample was the first to be exposed to TMAH' but does not use the word 'thermochemolysis'. Either find a source that uses that specific term (it appears in the original Nature Communications paper) or rephrase to 'first TMAH wet-chemistry experiment on another planet' which JPL does support.

Misattribution to JPL: TMAH chemistry mechanism ('hydrolyzes and methylates complex macromolecular structures') — JPL only says 'break apart larger molecules'

JPL's actual wording is: 'SAM can perform wet chemistry, dropping samples into a small cup of solvent. The resulting reactions can break apart larger molecules that would be difficult to detect and identify otherwise.' The terms 'hydrolyzes', 'methylates', 'macromolecular', and 'gas chromatography and mass spectrometry' do not appear in the JPL snapshot. Either source these technical descriptions from the Nature Communications paper or simplify to JPL's actual language.

Misattribution to JPL: 'gas chromatograph and a quadrupole mass spectrometer' description of SAM — not in JPL snapshot

The article writes that SAM 'routes those gases through a gas chromatograph and a quadrupole mass spectrometer to identify what is present, [JPL described]'. The JPL snapshot only mentions 'a high-temperature oven heats the material, releasing gases that instruments in the lab analyze to reveal the rock's composition' — no mention of gas chromatograph or quadrupole MS. Either source these specific instrument names from a different outlet or generalize to match JPL's wording.

Misattribution to Chemistry World: 4 of 7 molecule names not in Chemistry World snapshot

The article lists seven specific molecules detected for the first time and attributes the list to Chemistry World: 'benzothiophene, methyl benzoate, naphthalene, methylnaphthalene, dihydronaphthalene, trimethylbenzene, and tetramethylbenzene'. Chemistry World only explicitly names benzothiophene, methyl benzoate, and naphthalene by name. The other four (methylnaphthalene, dihydronaphthalene, trimethylbenzene, tetramethylbenzene) are not stated by name — Chemistry World refers generically to 'single and dicyclic aromatic molecules' and confirms 'seven, most of which had never been detected on Mars previously'. The specific names are likely in the Nature Communications paper itself or in NASA's full release; re-attribute or remove the four unnamed compounds.
