Summary

This episode of ‘Dernières nouvelles des étoiles’ covers three main space news stories. First, it discusses the recent anomaly in Boeing’s CST-100 Starliner launch abort engine during a test, which could further delay the already tight schedule for crewed flights. Second, it reports the discovery of 12 new moons around Jupiter by an international team, bringing the total to 79. The discovery was accidental, made while searching for Planet Nine, and highlights the ongoing surprises within our solar system. The new moons are small (1-3 km) and mostly retrograde, suggesting they are remnants of collisions. Third, it covers SpaceX’s successful launch of a heavy satellite (Telstar 19V) on a Falcon 9 Block 5, with recovery of the first stage, and mentions upcoming launches and fairing recovery attempts. The video also touches on the broader context of NASA’s commercial crew program and the potential gap in US access to space after 2019.
