Water
















Moon Landing MapCold War politics. Via the Technology Review’s Physics arXiv Blog:

The last Soviet mission to the moon, Luna-24, returned to Earth with water-rich rocks from beneath the lunar surface. But the West ignored the result.

The possibility of water on the moon has excited scientists and science fiction fans for decades. If we ever decide to maintain a human presence on the moon, clear evidence of water will be an important factor in the decision.

In recent years, that evidence has begun to mount. The data comes from several sources. First there was the pioneering Clementine mission in 1994, America’s first return to the moon in twenty years. Clementine looked for water by bouncing radio waves off the surface—the returns giving a strong indication that water ice must lie beneath the surface…


EuropaALL THESE WORLDS ARE YOURS EXCEPT EUROPA. ATTEMPT NO LANDINGS THERE.

Well after reading this story, enthusiasts will probably want to ignore the Monlith creators’ advice. As Robert T. Gonzalez writes on io9.com:

Remember that image from a few weeks back that showed Earth with all its water gathered up in a sphere beside it? Well here’s that image again, only this time, it also features Jupiter’s moon Europa, along with all of its water. Notice anything interesting?

Based on data acquired by NASA’s Galileo satellite, astronomers think the global oceans sloshing around beneath Europa’s icy exterior are likely 2 to 3 times more voluminous than the oceans here on Earth. Not 2 to 3 times more proportionally, 2 to 3 times more in total volume.

Yeah. That “little” moon is packing quite the supply of H2O—and with it, scientists think, a significant chance of harboring life…








Sand has been used as a purifier for thousands of years. An innovative way of cleaning water, by adding graphite waste, provides a cost affective way to bring purified water to those who may not normally have access to a clean water source. Via Treehugger:

The solution is cheap since the sources of graphite could include the waste produced by graphite mining companies that still contains a significant amount of graphite. And the researchers believe that it is possible to modify the graphite oxide to pick out particular pollutants and therefore tailor the super sand to specific areas that might be having trouble with certain water-borne diseases or pollutants.
