The Gaia mission App allows you to discover the details of Gaia, the cornerstone astrometry mission of the European Space Agency (ESA) to survey our Galaxy. The main goal of the Gaia mission is to make the largest, most precise three-dimensional map of our Galaxy by surveying an unprecedented one per cent of its population of 100 billion stars.
You will find all the details at the Materials | Aplications section, and more information about the Gaia research group at their website.
