   No need for a slight thrust; emulating lunar or Martian gravity is just   
   a matter of flying a slightly shallower parabola.  It's been done   
   occasionally.  But the available time at reduced G is too short for   
   some things; I think it would be quite a trick to get measurements of   
   things like this in the time available.
