As the title says, is it known how big, or massive, hayabusa2's sample is, due for Earth touchdown on 6th December?

I have tried some basic internet research but found nothing on the anticipated sample size.

Edit: Evidence that nobody knows yet would also be an acceptable answer.

    $\begingroup$ @uhoh - I'm certainly hoping they get more than they did with Hayabusa. $\endgroup$ Nov 24, 2020 at 20:43
