The Japanese Hayabusa 2 twitter account reports that the spacecraft has begun descending toward Ryugu in preparation to deploy the MASCOT lander. Nothing on the English twitter as of the time of this post.

In the cited article there is also an interesting reference to the discussion about dust (or rather its lack) on the surface of Ryugu, which I initiated on this forum a few months ago:
"...Ralf Jaumann and his team were particularly surprised by the lack of dust: "Ryugu's entire surface is littered with boulders, but we have not discovered dust anywhere. It should be present, due to the bombardment of the asteroid by micrometeorites over billions of years, and their weathering effect. However, as the asteroid has very low gravity – only one-sixtieth of that experienced on Earth’s surface – the dust has either disappeared into cavities on the asteroid or has escaped into space. This gives an indication of the complex geophysical processes occurring on the surface of this small asteroid...” |
