Planck is the third-generation satellite aimed at measuring the cosmic microwave background, a relic of the hot big bang. Its temperature and polarization maps of the millimeter-wave sky have constrained parameters of the standard lambda-CDM model of cosmology to incredible precision, and have provided constraints on inflation in the very early universe. Planck's polarized Galactic dust measurements at 353 GHz in combination with deeper suborbital maps of CMB polarization have tightened constraints on the gravitational wave background from inflation, in combination with BICEP2 and Keck data at 95 and 150GHz. We present highlights of these results and discuss future prospects for further measurements of early universe physics with the CMB from Planck and future space and suborbital platforms.
