7 The formation of stars

8 Gaia: a 3-D mapping of our galaxy

9 GAIA is going to detect and track : 10 9 (one billion) stars 10 6 – 10 7 resolved galaxies brown dwarfs extrasolar planets 200 gravitational lenses 10 7 resolved binaries 20 × 10 6 variable stars Tests of General Relativity and… – 10 6 solar system objects The numbers…..

10 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.
