Hayabusa2 Touch Down Video (「はやぶさ２」搭載小型モニタカメラ撮影映像)
This video, taken by the Hayabusa2 probe, shows it landing on the Ryugu asteroid and then firing a 5-gram tantalum bullet into the surface in order to collect subsurface samples.
Incredible to see the surface of the asteroid so close, and even more amazing to see the effect the bullet has when it hits the surface at 300 meters per second!
