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.
