Summary

This episode of ‘Dernières Nouvelles des Étoiles’ (DNDE) covers recent space news. The host begins with an update on Fast Radio Bursts (FRBs), explaining that a new study has found a FRB in a quiet galaxy, challenging the previous hypothesis that FRBs originate from galaxies undergoing collisions. He then discusses the Chinese rover Zhurong, which has found evidence of past ocean activity in the Utopia Planitia region, based on analysis of 106 panoramas showing deposits consistent with ebb and flow. Next, he reports on the partnership between Relativity Space and Impulse Space to launch a private Mars mission in 2026. Finally, he covers the failure of the Hakuto-R lunar lander, which crashed due to an altitude miscalculation, and the bankruptcy of Virgin Orbit, with its assets sold to competitors. The episode concludes with a reminder of the live show and upcoming content.
