MUSES-C Launched

Anonymous Coward writes "If all goes well, Japans MUSES-C asteroid probe will be bringing back samples from an asteroid in less than five years. Launched friday afternoon at 1:29 pm (local time) the probe should reach its target in June of 2005. The MUSES-C probe will collect surface samples of asteroid 1998SF36 totaling 1 gram, including sand and stone fragments, two years later before returning to the Earth in June 2007, researchers said."

FYI, old spy satellites used to drop rolls of film. I'm not sure about the mechanism though.

Still no complete answer, but I found this link:

Excerpt: Muses-C spacecraft will also fire explosive charges into the asteroid, collect the samples that are ejected from the impacts, and return the samples to Earth in a capsule for
laboratory analysis

and this:

In this mission, the spacecraft will land on the asteroid surface, sample the surface rocks/soils and encapsulate them into a container. We will recover the samples carried by the entry capsule which will provide us with many findings of primitive bodies in the solar system.

Re:1 gram?

The probe is going into orbit around the sun so I bet when it comes back it will be moving far too fast to get into a low earth orbit where it could be grabbed by a spacecraft. You could put a big rocket on it to slow it down ($$$) or just let it rip into the atmosphere for free.
