Le retour d'échantillons d'Hayabusa 2 en live

This live broadcast from Ciel & Espace covers the return of the Hayabusa2 capsule to Earth on December 5, 2020. The show features two expert guests: Patrick Michel, a CNRS astrophysicist and member of the Hayabusa2 science team, and Hadrien Devillepoix, a meteorite specialist from Curtin University who is leading a team to observe the capsule’s re-entry. The broadcast begins with Devillepoix explaining his team’s preparations in the Australian desert, including deploying 83 instruments to study the controlled re-entry of the capsule. After Devillepoix leaves to observe the event, Michel provides an in-depth overview of the mission’s significance, detailing the scientific goals of studying asteroid Ryugu, a primitive carbonaceous asteroid. He explains that the samples could provide insights into the formation of the solar system and the origins of life on Earth. Michel recounts the mission’s challenges, including the surprising rocky surface of Ryugu, the development of new landing strategies, and the successful deployment of rovers and the MASCOT lander. He also describes the risky impact experiment that created a crater on the asteroid’s surface. The broadcast captures the tension and excitement of the capsule’s re-entry, culminating in the successful landing in Australia.
