   If the rock of doom requires a gentle nudge away from Gaia to
   prevent a very bad day for Earthlings, NASA won¢t be riding to the
   rescue. These days, NASA does dodgy weather research and outreach
   programs, not stuff in actual space with rockets piloted by
   flinty-eyed men called Buzz.                       -- Daily Bayonet
