    Anyone that's ever tried to plan an outdoor activity in advance knows that weather forecasting is not an exact science, but the perpetual sky-watchers at NASA may have inadvertently found a way to improve these guesstimations. They have been testing a laser system for measuring lunar dust and soil kicked up by rocket exhausts, and while using precipitation as a substitute to calibrate the laser, they found they could measure the average size of raindrops passing through it. This value is estimated in current forecasting models, so plugging in some accurate numbers should make those predictions more reliable. The original mission hasn't been forgotten, though. Particles whipped up by landing rockets on the moon's surface could damage what was left behind by the Apollo missions, ruining its scientific and historic value. One of the laser sensors may find its way onto a craft vying for Google's X Prize, with the results used to determine where vessels can touch down whilst keeping a safe distance from Apollo landing sites. Although an accidental discovery, the system's other potential career in weather forecasting will also continue to be explored. Now, if only there was a way to make it rain and speed up the testing.

  • X Prize adopts NASA guidelines for protecting lunar heritage sites, Buzz Aldrin punch averted

    NASA hopes that one small step by Google's Lunar X Prize will eventually lead to a giant leap in protecting historical sites on the moon. The X Prize Foundation announced that it will adopt guidelines released by the space agency last year to help preserve lunar heritage sites. The move comes at a crucial time as a new space race increases the possibility of an imminent moon landing, according to NASA. Google's Lunar X Prize alone currently has 26 contestants worldwide vying to land a robot on the lunar surface by 2015. NASA stressed that their recommendations aren't law and "do not represent mandatory U.S. or international requirements." Examples include approach and landing guidelines to minimize disturbance, contamination and degradation of Apollo mission sites. That certainly sounds more reasonable than, say, plopping some dude in a spacesuit at a lunar outpost to shoot trespassers with a plasma shotgun while yelling, "Get off my property!" In the meantime, feel free to mosey on over to the PR after the break.
