For those who haven't seen it yet,
<https://www.youtube.com/watch?v=-3hO58HFa1M> is JAXA's video of the
Hayabusa 2 sampling touchdown on Ryugu. (The little white spot in the
lower-left corner of the early part of the video is the target marker --
dropped a while ago -- that the guidance system was using as a navigation
reference.)
<http://www.planetary.org/blogs/jason-davis/hayabusa2-touchdown-video.html>
has that, some more background info, and a short repeating clip of the
actual touchdown.
