Why it matters

Mjølnir expands the Earth catalog and shows the range of confirmed impact structures by scale, age, and preservation state.

What happenedMjølnir is a confirmed terrestrial impact structure in a terrestrial setting under editorial verification. This profile records a listed diameter of 40 km and keeps the object ready for editorial expansion.

Seed record: coordinates and diameter support navigation, while geology, age, and visual rights need enrichment.

Profil scientifique

The production profile should further document target rocks, preservation state, shock evidence, and the confirmation history of the impact interpretation.

Si l'image vérifiée ne suffit pas, la fiche reçoit une reconstruction scientifique : non pas de la fantaisie à la place du fait, mais une hypothèse visuelle séparée des sources.
