  Dirty Rotten Snowballs

"It's not your father's solar system" - says SpaceDaily - Until now, comets have been dubbed "dirty snowballs", but it might be appropriate to call them "snowy dirtballs" given the extraordinary dominance of ultrafine dust.

Not only that, but the deep impact probe - a few hundred kilograms of impactor - liberated over 5000 tons of water from Comet Tempel1 - in case you weren't paying attention, that's more water in solar orbit than a shuttle could lift in a thousand missions, more water than is known to exist on Mars or the moon - frozen there - and on every comet and probably most asteroids, waiting for us, in a fine dust that would be easy to convert to clean, usable water....

Now if we can only summon the international nerve to get our materials for space development from space - more than just the 100 milligrams that Hayabusa is returning!
