Summary

This episode of ‘Dernières nouvelles des étoiles’ (DNDE) covers several space news items. The main story discusses a new experimental approach to detect dark matter axions using a quantum crystal of beryllium ions, which could detect the electric field produced when axions convert to photons in a strong magnetic field. The video also covers the upcoming Inspiration4 mission, SpaceX’s progress at Starbase with the assembly of Starship prototypes, a new Falcon Heavy contract for NASA, Blue Origin’s New Glenn progress, the US Department of Defense’s interest in nuclear propulsion, and a detailed study of the asteroid 216 Kleopatra, revealing its low density and the likely formation of its moons from ejected material. The presentation is clear and accessible, with a mix of scientific explanation and news updates.
