Floating Between Mars and Jupiter, Ceres May Have More Water Than Earth (nasa.gov)
This week NASA's Dawn space probe swooped within 22 miles of the surface of Ceres, the dwarf planet that's the largest object in the asteroid belt between Mars and Jupiter. NASA's JPL reports:
In more than three years of orbiting Ceres, Dawn's lowest altitude before this month was 240 miles (385 kilometers), so the data from this current orbit bring the dwarf planet into much sharper focus... "[T]he results are better than we had ever hoped," said Dawn's chief engineer and project manager, Marc Rayman, of NASA's Jet Propulsion Laboratory, Pasadena, California. "Dawn is like a master artist, adding rich details to the otherworldly beauty in its intimate portrait of Ceres."
EarthSky reports NASA captured an up-close glimpse of those tantalizing bright spots on Ceres: The spots, evaporate deposits composed of sodium carbonate, are thought to be left over from when water came up to the surface from deeper below and then evaporated in the extremely tenuous and sporadic water vapor "atmosphere." That water could be either from a shallow sub-surface reservoir or from a deeper reservoir of salty brines percolating upward through fractures. The deposits in Occator Crater are the largest and brightest of these deposits. As with many discoveries in planetary science, they were completely unexpected, and show that Ceres is not just an inert ball of rock and ice.
Slashdot reader thegameiam adds: Ceres may have more fresh water than exists on Earth. Perhaps this would make colonization of the asteroid belt more of a possibility?

"Ceres: having more water than Earth since at least 2005"
Ezekiel 23:20
... lazy and stupid assess out there into space. Humanity has yet so much to do but somehow only the war mongering and pretty idiots seem to be in charge. How I wish we could move on further and faster than we are. .... I really wish to see the Advent of feasible space colonization in my lifetime. That would be cool. And restore my faith in humanity.
We suffer more in our imagination than in reality. - Seneca
Have you considered that we evolve the species epigenetically through BEHAVIOR and the choices we make in our lifetimes? Perhaps what he suggests is precisely how we evolve ourselves to be less selfish and more cooperative: it's an endeavor that would require global participation and cooperation. That cooperation might be grudging during our lifetimes, but if that behavior becomes ingrained in our epigenetics then we might indeed achieve what you want at the same time. You think that these two activities must be separate and one precede the other, but I'm not so certain.
