Lua: água - e não é que Obama desistiu (por enquanto, espero) de ir lá; que nos valha a China!

"It's no longer a question of if there is water on the Moon; now it is how much. Scientists using the Mini-SAR instrument on India's Chandrayaan-1 spacecraft have detected water ice deposits near the moon's north pole. Mini-SAR, a lightweight, synthetic aperture radar, found more than 40 small craters with water ice. The craters range in size from 2 to15 km (1 to 9 miles) in diameter. Although the total amount of ice depends on its thickness in each crater, it is estimated there could be at least 600 million metric tons of water ice."
