How did Hayabusa shoot the dirt in the tube?
Hayabusa went to the Itokawa asteroid, and, according to news reports,
fired a bullet that forced asteroid material into a tube. But if the bullet didn’t work, the Hayabusa people hope some material went up the tube as a result of the landing. Fine with me, but I’m having trouble visualizing what this bullet-tube arrangement is. Did the lander shoot the bullet downward? Then did the material just back-puff up into the tube because of the bullet impact? Does anybody know how this was arranged? It seems there should be a diagram somewhere. Never mind; I just found a link http://www.astro.mech.tohoku.ac.jp/h...e1_english.htm I'll have to study it. The news photos showed guys in some kind of protective suits looking at the capsule (the thing containing the asteroid dirt) where it landed on the ground in Australia. It was going to stay there for three days then be flown by charter plane to Japan to be opened. Why wait 3 days to send the capsule? The thing is small enough to go in the overhead compartment on a commercial flight. What’s wrong with that? And what’s with the protective suits? These guys are letting their imagination get the best of them. It’s kind of cold out there on Itokawa. ~{|) Nehmo (|}~ |
