Summary

This episode of ‘Dernières Nouvelles des Étoiles’ (DNDE) covers several space news items. The main story is the detection of a rogue black hole in the Milky Way using gravitational microlensing. The black hole, about 7 times the mass of the Sun, was identified by analyzing the light distortion of a background star over six years. The video also discusses the creation of Quantum Space, a company aiming to provide services in cislunar space, and the delay of Artemis 1 launch to spring. It reports on China’s test of a high-power Hall-effect thruster (HET-450) and the challenges of powering it. Finally, it updates on the InSight lander’s deteriorating power situation due to dust accumulation on its solar panels, predicting its end of mission in 2022.
