Conclusions
Conclusions The Bologna Observatory of
INAF participates in fundamental aspects of the
Gaia mission, with a significant amount of
resources and of expertise. Much work has been
done but we just started. Launch is foreseen in
2012 and we need funds and manpower to complete
the assigned tasks.
