Conclusions: If Planck is successful, will very likely complete 4+ sky surveys. Powerful probe of inflation. Accurate measurements of scalar modes. Non-Gaussianity limits f ~ 5. Large scale polarization measurements. 95% upper limit of r ~ 0.03. Competitive with the most sensitive ground based/sub-orbital expts. Only experiment that can probe low multipoles (l < 10).
