TALK: The Planck mission

ABSTRACT: The Planck mission of the European Space Agency has measured the Cosmic Microwve Background (CMB) coming from the early universe with unprecedented accuracy in intensity and polarization. It involves technologies flown for the first time in space for the detectors and the cryogenic chain.
The Lambda-Cold Dark Matter model based on général relativity and the présent knowledge of particle physics has only 6 parameters to be determined from the observations.
The mission was launched in 2009 and the Planck collaboration will release the final data to the scientific community this summer together with the papers describing the analysis. The polarization data have been now use fully and are in excellent agreement with the cosmolgical model derived from the intensity.
The inflation paragdigm is now tested for three of its generic prédictions with High accuracy. Tighter contraints on physics (for ex on neutrinos masses) have been obtained. Nevertheless there are tensions with cosmological parameters from astrophysical measurements. These will be discussed.
