Fact-check log

On 15 November 2026, each numbered claim on this site was checked with a regular-expression search against a cached excerpt of its source page. 44 claims, 44 matches, 0 misses. The live pages may later change; the excerpts we checked are kept with the build.

Where NASA Science rounds a figure that the fact sheet gives more precisely, both are kept and labelled, rather than silently averaged.
