In the summer of 2018, the Hayabusa 2 spacecraft arrived at the Ryugu asteroid and in October of that year sent out the Mobile Asteroid Surface Scout (MASCOT) lander to gather information about the surface.
Now the images taken during its 17 hour mission
have revealed something interesting. The asteroid, just over half a mile in diameter, has rocks like carbonaceous chondrite meteorites but there seems to be no dust, like is on the moon. The rocks
are instead "bright, with smooth faces and sharp edges, or dark, with a cauliflower-like, crumbly surface."
