Gaia – Surveying a billion stars

Welcome to ESA’s Gaia blog! Gaia is a global space astrometry mission. It will make the largest, most precise three-dimensional map of our Galaxy by surveying more than a thousand million stars. In this blog we’ll cover the activities from Kourou from once the spacecraft has left the clean room in Toulouse until launch. And we’ll include guest blogs from outside of Kourou – to give you an idea of the other things that are happening in the wider Gaia community. Details shortly…Watch this space!
