Summary

This video from the ‘Les Dossiers de l’Espace’ series provides an overview of asteroid exploration as of 2018. It begins by highlighting the diversity of asteroids and their scientific importance, then reviews past missions such as NEAR Shoemaker, Hayabusa, and Dawn. The main focus is on two upcoming missions: JAXA’s Hayabusa2, which will study the C-type asteroid Ryugu, and NASA’s OSIRIS-REx, targeting Bennu. Both missions aim to return samples to Earth, with Hayabusa2 also deploying rovers and an impactor. The video explains the scientific goals, including understanding the early solar system and the potential role of carbonaceous asteroids in delivering organic compounds. It also mentions future missions like Psyche and Lucy, and the emerging role of private companies in asteroid prospecting. The presentation is clear and accessible, with good use of visuals and explanations.
