On October 7, NASA published the preliminary Artemis II lunar science report. It brings together photographs, recordings and observations from the April 6, 2026 lunar flyby: the new development is the release of results, not another journey. The crew reported five faint impact flashes while viewing the Moon under particularly dark conditions. [1]

The document also describes colour differences on the surface, which researchers can compare with spacecraft imagery and other measurements. Human observations add details and questions; the report is preliminary and cannot by itself establish every cause or characteristic of the impacts. NASA presents the material as a resource for analysis and planning future missions. [1]
