Summary

This episode of ‘Dernières nouvelles des étoiles’ (DNDE) covers several space news items. The main focus is on a new bimodal nuclear propulsion concept funded by NASA’s NIAC program, which could potentially reduce travel time to Mars to 45 days. The video explains the principles of nuclear thermal and nuclear electric propulsion, and how combining them could offer high thrust and high efficiency. It also discusses issues with two NASA missions: Lunar Flashlight, a cubesat experiencing thruster problems, and Lucy, a probe with a solar array deployment issue. Additionally, it reports on the upcoming launch of the Psyche mission and the progress of Chinese private space companies, particularly Space Epoch’s mini-Starship and its methane engine tests. The video concludes with updates on SpaceX’s Starship, anticipating a possible orbital test in early 2023.
