  23. It seems to me this is a case where GEO would help.  Deploying a few
  24. really BIG guidable antenna arrays in geosynchronous orbit, parked over
  25. dedicated ground stations, would allow tracking and commanding probes
  26. all over the solar system without usurping valuable observatory time.
  27.  
  28. Such big antennae might in principle be useful for radio astronomy too,
  29. but in practice you'd only need to build the horns for the bands space
  30. probes use, and image resolving ability would not be a priority.  This
  31. should remove a lot of the lavish expense and operational headaches
  32. that would attend an full-fledged orbiting radio telescope.
