NASA's much anticipated LCROSS mission sent two spacecraft "bombing" into the moon early this morning. The craft successfully struck their target, a crater thought to harbor frozen water. But the much-hyped moon show that had been expected to accompany the impact, however, turned out to be a flop—no billowing plumes of dust and ice visible through backyard telescopes or on NASA TV. The low-impact impact had one NASA expert musing that LCROSS may have struck a "dry hole." (source: news.nationalgeographic.com)
