The interstellar dust collector is scheduled to return to earth tonight - filled with 45 teeny tiny particles of galactic stardust. How cool is that?

And NASA is recruiting internet volunteers to help them locate the bits (so small that even though they're contained in a single square foot, locating the particles is akin to searching for 45 ants on a football field).

And if you manage to find one, you get to name it! I was thinking Cynthia, maybe.
