Première mondiale: la sonde japonaise collecte des échantillons dans un cratère de l’astéroïde Ryugu
La mission japonaise Hayabusa 2 a récolté des poussières de roches souterraines sur l’astéroïde Ryugu (2 fois la distance du Soleil !), le 11 juillet 2019, trois mois après les avoir mis au jour en creusant un cratère à l’explosif.
In world first, Japan’s Hayabusa2 probe collects samples from distant asteroid after second successful touchdown
Hayabusa2 touched down on its targeted area measuring 7 meters in width, located 20 meters from the artificial crater’s center. The probe extended a tube to the surface and fired a small metallic projectile from it, successfully capturing the subsurface debris as it floated up, the agency said.
The brief landing Thursday was the second time Hayabusa2 has touched down on the asteroid, which is about 300 million kilometers from Earth.
The complex multiyear mission has also involved sending rovers and robots down to the surface.
