A Japanese spacecraft just grabbed more rocks from the asteroid Ryugu www.technologyreview.com

Hayabusa2 has collected a second sample from the asteroid’s surface.
It could give us a unique insight into how the early solar system was formed.
The procedure: After a few hours of maneuvering, the spacecraft touched down on Ryugu’s surface at 9:15 p.m.
It then fired a bullet into the asteroid and collected some of the debris stirred up by the shot.
In April, Hayabusa2 had also fired a copper bomb into the asteroid’s surface to expose the rocks beneath, in anticipation of today’s mission.
