Two decades after the first production of (relativistic) antihydrogen atoms, and a good decade after the first production of “cold” antihydrogen, first measurements of the properties of antihydrogen have recently begun. Together with the start-up of an additional dedicated low energy antiproton decelerator (ELENA), and the development of a wide range of techniques that permit precise atomic measurements, the study of antihydrogen atoms is set to start in earnest. This presentation will provide an overview of the present status and outlook for fundamental physics with antihydrogen atoms. A special focus will be put on the AEGIS experiment, which in a first step aims to reach a 1% precision on the gravitational interaction of antihydrogen by measuring its free fall over its parabolic trajectory, as well as on the technological developments from a variety of fields on which it relies.
