A new CCD camera is being constructed for the 4 m Blanco telescope in Chile for the Dark Energy Survey. The survey will begin in about a year and will study dark energy via supernova Ia distances, galaxy angular clustering, weak gravitational lensing, and baryon acoustic oscillations. Details of the project and the science will be described.
