After only ten hours' exposure to lunar dust from the Sea of Tranquility, the bacteria had died...
Extra Caution. What that deadly substance was, no one knows. NASA scientists point out that many plants, such as ferns and liverworts, have actually grown better in lunar soil than in terrestrial soil.
