Science trivia: The heart of a fruit fly beats at about the same pace as yours. So the space folks are sending 400 adult fruit flies and 2,000 eggs up to the Space Station to orbit for a month for an experiment on long term weightlessness. Also, without gravity pulling down, the bones of astronauts turn fragile. They don't want any fractures on a trip to Mars. This obsession with weightlessness recalls the story dating back to the early days of NASA where they were wondering whether an attack of flatulence in zero gravity might propel one thru the capsule and crash against the bulkhead. A weighty subject to ponder!
