Smallest repair: attribute the argument to NASA's NESC technical bulletin, for example 'A NASA NESC technical bulletin argues', and drop the personal claim of authorship unless it is confirmed.","excerpt":"For more information, contact Joel W.

The reading never says what hammer tests are for, such as modal analysis of structures before pyroshock testing, or that NASA is the institution behind the bulletin. A general reader cannot grasp the development or why it matters. These terms need plain-language explanation or tooltips. The question is reasonable and follows from the source.","excerpt":"Hammer tests support modal analysis [2–4] and can precede pyroshock testing [6]."},{"dimension":"date","status":"pass","explanation":"The originalPublished value, 2026-11-02T15:47:41-05:00, matches the page date of Nov 02, 2026 and the feed entry.
