Summary

This episode of ‘Dernières Nouvelles des Étoiles’ (DNDE) covers the latest space news, focusing on the interstellar object 3I/ATLAS. Recent observations show that 3I/ATLAS has become unexpectedly brighter as it moves away from the Sun, likely due to delayed heat reaching fresh ice layers. This provides a unique opportunity to study its deeper composition, revealing more water and organic compounds like methane and methanol. The video also discusses the Artemis II delay due to hydrogen leaks, a recurring issue inherited from the Space Shuttle program. China is preparing an in-flight abort test for its Long March 10 rocket and Mengzhou spacecraft, with a possible booster recovery attempt. Blue Origin is advancing its lunar ambitions, including a possible reusable second stage for New Glenn and a habitable Blue Moon variant. Finally, the European company OHB has founded a ‘European Moonport Company’ to support an independent European lunar presence. The episode concludes with a promotional challenge from Hyprspace.
