The ESA Planck mission will survey the entire sky using radiometers at 30, 44, and 70 GHz and bolometers at 100, 143, 217, 353, 545, and 857 GHz. This will be the first all-sky survey at submillmeter wavelengths with resolution better than 1 degree. The Early Release Compact Source Catalog (ERCSC) will provide source lists derived from the first sky coverage at the 10-sigma level. The source lists will be available to all scientists approximately 20 months after the joint Herschel/Planck launch, in time for the first post-launch call for Herschel observing proposals. Planck's capabilities are suited to cold objects as well as those with bright free-free radiation from ionized gas. Detected sources will include extragalactic objects, in particular flat-spectrum radio sources (like blazars) at low frequencies and redshifted galaxies (whose dust emission peaks in the high frequencies). Galactic sources will include HII regions and cold cores in molecular clouds. Since Planck will perform the first all-sky survey at many of its frequencies, we also anticipate some surprises!
