Particles In Hayabusa

Scientists carefully opening Japan's Hayabusa spacecraft, which hopefully has returned dust samples from the asteroid Itokawa, have in fact found particles inside the probe's Chamber A. The next step is to determine whether the particles are from Itokawa, or whether they are contamination from Earth.

And yes, there is a Chamber B, which also might contain samples. It will be opened at a later date.

Successfully returning asteroid samples on this mission would cement Japan's position as a major player in robotic space exploration.
