I missed this year’s Hayabusa Symposium, sorry. I was too tired from European Time to switch to Japan Time. And besides, the European Asteroid Size conference was looking forward, Hayabusa meetings are now (mostly…) looking back. In any case, this year’s meeting:

The Hayabusa Symposiums have been going on for years now, ever since Hayabusa 1 gave us samples of Itokawa. Samples sealed into a return chamber, without a fiery entry and ground impact. The meetings also coincide with Japan’s Polar Research meetings, which is no accident- Antarctica’s ice sheets are, by a large margin, the #1 source of meteorites, including rare groups. (Hence, M. Zolensky is there.) Between those sample sources, it’s a geochemical/cosmochemical smorgasbord, which is why K. Lodders is there. Wish I was there.
