The Fermi Gamma-Ray Space Telescope was launched on June 11, 2008
and has since then operated successfully on-orbit.
The gamma-ray sky is dynamic on very short time scales,
multi-wavelength observations are necessary to fully understand
astro-physical objects and the Fermi LAT photon data are public. This
means the fully reconstructed, calibrated and validated science data have
to be available as quickly as possible.
In this talk I will describe how these challenges were met and how
we process and monitor the science data from the main instrument on
Fermi, the Large Area Telescope.
