O6.1 How is Gaia doing at L+10m?

Uwe Lammers (European Space Agency)

William O'Mullane, European Space Agency

ESA's 1000-Million star surveyor Gaia was launched past December from French Guiana. Following a perfect launch towards L2 is has been commissioned over the early months and entered into the nominal mission phase planned to last 5 years. We will describe the status of the space and ground segment with emphasis on the complex distributed data processing system designed to keep up with the several 10 GB of telemetry streaming in every day. Apart from the near-real-time processing a second tier of systems will soon shift into the focus. After years of validation with simulation data these cyclic processes are slowly being bootstrapped with real flight data and readied to produce the first public catalogue scheduled for L+31m.
