  21. 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).
