27555084 story SETI To Scour the Moon For Alien Footprints? 167 Posted by Soulskill on Tuesday December 27, 2011 @06:21PM from the just-an-old-hierarchy-monitor-station-and-some-robots dept. astroengine writes "Although we have an entire universe to seek out the proverbial alien needle in a haystack, perhaps looking in our own backyard would be a good place to start. That's the conclusions reached by Paul Davies and Robert Wagner of Arizona State University, anyway. The pair have published a paper in the journal Acta Astronautica detailing how SETI could carry out a low-cost crowdsourcing program (a la SETI@Home) to scour the lunar surface for alien artifacts, thereby gaining clues on whether intelligent aliens are out there and whether they've paid the solar system a visit in the moon's recent history."
