Astronomer Carme Jordi gave the talk on the Gaia mission A billion eyes for a billion stars in the Astrobanyoles Association, last January. You can retrieve it on the YouTube channel of the Association.
Carme Jordi is a researcher at our Institute and a professorat the Faculty of Physics of the University of Barcelona. She is a member of the Gaia team at UB, and her research is framed in galactic astronomy and stellar physics, in particular, the physical characterization of stars and star clusters as tracers of the Galaxy's disk. Her research is based on astrometric, photometric and spectroscopic observations made from observatories in Catalonia, Spain, Chile, Mexico, France, Hawaii and from space.
The Gaia project is one of the most technologically advanced and precise instruments ever built in space. Its two telescopes are mounted on a silicon carbide toroidal structure that is both durable and lightweight. Its solar panels provide the necessary energy for the satellite (little more than what is needed for a dishwasher). The installation of each element on the satellite must be extremely precise to ensure the success of operations during the mission.
