Summary

In this live episode of DNDE, Hugo Lisoir discusses recent space news, starting with the James Webb Space Telescope’s direct image of the exoplanet Epsilon Indi Ab, a ‘super Jupiter’ located 12 light-years away. He explains the significance of this observation, as it is the coldest exoplanet ever imaged directly, thanks to JWST’s MIRI instrument and coronagraph. The host details the methods of exoplanet detection (radial velocity, transits) and why direct imaging is challenging, emphasizing the importance of proximity and orbital separation. He then covers the cancellation of NASA’s VIPER lunar rover, citing budget overruns and risks. The show also discusses ESA’s initial studies on human-rating Ariane 6, delays in the Themis reusable first-stage demonstrator, and the potential return to flight of the Falcon 9 after an anomaly. The host shares personal anecdotes about Boeing aircraft issues, adding a relatable touch. The presentation is accessible, with technical explanations suitable for a general audience interested in space.
