More than one moon and exposing biomolecules to rigors of space

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - The prevailing theory about the formation of the moon is called the giant impact hypothesis: the theory goes that a Mars-sized object, known as Theia, crashed in to the young Earth. What left was Earth, and its moon. A new computer model suggests, however, that the Moon may not have been the only reminder of that big collision. See article.
g Life - Scientists have previously exposed organisms and biomolecules to the many rigors of space, but those experiments only managed to take "before" and "after" pictures of their samples. A planned small satellite will monitor on a continuous basis the negative effects of space on biology. See article.
g Cosmicus - As NASA prepares for its final service call to the Hubble Space Telescope, it's also preparing for something never attempted in the history of the shuttle program: a rescue operation so dramatic that Hollywood would be hard-pressed to come up with a more outlandish plot. See article.
