ESA's space astrometry mission Gaia started its scientific operations in July 2014. Gaia has already delivered an immense dataset of high-accuracy positional and photometric observations which already led to three Data Releases containing high-accuracy data of over 1.8 billion sources. In this presentation I will briefly overview the principles and ideas of space astrometry with Gaia. I will review the challenges of Gaia data processing and highlight some recent results. I will also outline what we have to expect from Gaia in the next several years.
