Looking for aliens on the Moon?

New Scientists is running the report: "Looking for aliens on the Moon",an idea that might sound crazy at first. Can we find a black monolith like the one in 2001, A Space Odyssey? Maybe not, but small alien objects would survive the long journey better than radio signals, as suggested in the 2004 Nature article “Inscribed matter as an energy-efficient means of communication with an extraterrestrial civilization”. The moon is a logical place to look for these alien objects because there is no atmosphere to destroy or denature them. The problem is: we need to send a lot, a lot of robotic microscopes and spectrometer to the Moon. (Image: the discovery of monolith from Movie 2001, A Space Odyssey, credit: TheFreeDictionary.com.)
