The Hayabusa-2 science team has released before and after images of the spot on Ryugu where the spacecraft’s explosive projectile caused the creation of a small crater.
On the left above is the before, with the new crater indicated by the circle on the right. Note the rocks in both pictures, some now partly covered with debris. They did not give a scale, but this is a very small area, probably less than a few feet across.
They now need to analyze whether they can safely touchdown at this spot and grab a sample.
