The DarkSide Dark Matter Search Program is a on direct-detection search for dark matter using a Liquid Argon Time Projection Chamber. The detector is designed to be free of background, and background-rejection techniques have been developed to this aim. The current detector, DarkSide-50, has a 156 (36.9) kg total (fiducial) target of "underground argon", and is surrounded by a layered 20 + 1000 ton active veto system.
Projected developments for detectors of increasing size are briefly mentioned.
