After eight months to prepare, Hayabusa 2 came off briefly on the face of Ryugu and led a "bullet" that allowed the collector to collapse after breaking. Then, Hayabusa 2 will "shoot" a 2.5-kilogram copper rod to Ryugu later this year, hoping to blow a crater created personally to facilitate the collection of deeper samples. After that, Hayabusa 2 is expected to leave Ryugu in December this year. It will take about a year for the return trip. At the time, we'll have a direct sample of the end to understand the composition and history of the asteroid!
