The PLANK satellite: Status & perspectives

I review the status of development of the PLANCK project which is slated for launch mid-2008. In particular, I illustrate the type of scientific results to expect in light of the current knowledge of the two on-board instruments. Indeed both instruments have now been delivered to industry for integration and they have been fully tested. This leads us to anticipate that the steady and fast rate of progress enjoyed by cosmology, in particular through the constraints given by the analysis of the Cosmic Microwave background (CMB) will continue unabated in the years to come.
