We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.
This is a fiction/fan codex: entries describe an in-universe canon. Our audits check canon and internal consistency — external fact-checking does not apply the way it does on real-subject codexes.

The Hermes Program — The Hermes spacecraft does not have a rotating section to provide artificial gravity; in the novel and film, it uses constant acceleration from its ion drives to simulate gravity, not a rotating section.
The Ares 3 Mission — The 'DID YOU KNOW' section states the dust storm was later determined to be a rare but survivable event, which contradicts the book/film where the storm is portrayed as genuinely life-threatening.
The Martian FTL Drive — The Martian does not feature an FTL drive; the story uses conventional chemical rockets and a gravity assist (the 'Rich Purnell Maneuver') to rescue Mark Watney, not faster-than-light travel.
The Martian FTL Drive — The Ares III crew did not develop any FTL drive; the rescue plan was devised by NASA and JPL engineers, and the crew's role was limited to executing the maneuver.
The Jovian Empire's Gravity Plating — The Jovian Empire does not exist in the canon of *The Martian*.
The Jovian Empire's Gravity Plating — Gravity Plating is not mentioned or implied in the book or movie.
The Black Legion's Neural Scrambler — The Black Legion and the Neural Scrambler do not exist in the canon of The Martian (novel or film).
The Black Legion's Neural Scrambler — The device is described as appearing in The Martian (novel/film), but no such weapon appears in either the novel by Andy Weir or the 2015 film adaptation.
The Therian War-Suit — The Therian War-Suit does not appear in Andy Weir's novel *The Martian*; no such exoskeletal combat armor is mentioned in the book.
Abandonment of Mark Watney — The dust storm winds are described as 'screamed past 150 kilometers per hour,' but in the novel, the wind speed is given as 175 kilometers per hour.
Abandonment of Mark Watney — The comparison to Gus Grissom is inaccurate: Grissom was not 'nearly left behind during a Mercury mission.' There is no canonical basis for this comparison in The Martian.
The Hab Explosion — The explosion is caused by burning hydrazine with oxygen and a valve failure leading to hydrogen gas ignition, not by a pressure imbalance or modifying pressure systems to create water from hydrogen and oxygen.
The Hab Explosion — The explosion does not destroy Watney's potato crop because the potatoes haven't been planted yet at that point in the timeline.
