I mention that meteoritics, the study of meteorites in hand, often drills much deeper than astronomy (observing dots in the sky), or actual space flights (limited by mass, volume, power, data, etc.). In this paper (in the Dec. issue of… Read More »Note, Paper: Ge-ex-chimica
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… Read More »2024 Hayabusa Symposium
