Though strong interaction has been studied for quite a long time, recent findings of new and unexpected resonances, with unresolved properties like the X(3872), show that the hadron spectrum is far from beeing completely understood. This is also underlined by the ongoing discussion on the existence of multi-quark states, and other exotic states with gluonic degrees of freedom.

An antiproton beam of unprecedent intensity and quality will be soon available at the HESR machine, foreseen as one of the the new FAIR accelerators of Darmstadt. This tool, together with a properly designed new detector (PANDA), will be the ideal environment to copiously produce a wide spectrum of hadrons.

In the past, experiments with antiprotons have already demonstrated to be a rich source of information on many aspects of non-perturbative QCD. The better characteristics of the beam, and the new generation experimental setup will allow to address and clarify most of the open questions in a direct way.

A review of the PANDA experimental progam, and of the detector setup, will be given.
