In spring 2003, the B physics era ended for the CLEO experiment with a final run at the Y(5S) resonance. Over the summer the experiment and the CESR accelerator were modified to operate at lower center-of-mass energies between 3 and 5 GeV. In September 2003 the CLEO-c detector has begun to take its first data at the psi(3770) resonance, with which a new era for the exploration of the charmonium

The CLEO-c research program presented here will include studies of leptonic, semileptonic and hadronic charm decays, searches for exotic, gluonic matter and test for new physics beyond the Standard Model.
