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.
