The GAIA data challenge

• Over the nominal mission lifetime of five years,
  Gaias payload will yield a total uncompressed
  data volume of around 100 terabytes. The
  satellite will have contact with the ground
  station once a day for a mean duration of 11
  hours, during which an uncompressed data volume
  of roughly 50 gigabytes will be down-linked at a
  rate of a few megabits per second.
