Water on the Moon
In case you haven’t heard yet, there is quite the buzz building about three separate results that indicate that there is water on the lunar surface. There isn’t much: moon rocks returned by Apollo are pretty darn dry, but it’s still an exciting result, and it means that future missions might be able to extract water for drinking and rocket fuel. I was especially surprised to hear that the water is not just in the frigid craters at the moon’s poles that never see the light of day. Instead, it is found over large portions of the surface! The other surprise is that one of the data sets used to make this discovery is about 10 years old!
