The DARK ENERGY SURVEY, status, current results, and mocks.

The Dark Energy Survey (DES) is an ongoing large galaxy survey that aims to unravel the nature of the dark energy,  which powers the current accelerated expansion of the universe. By the end of the five seasons of observations DES will have measured the position on the sky, redshift and shape of almost 300 million galaxies, together with thousands of galaxy clusters and supernovae. DES will study the properties of dark energy using four main probes: galaxy clustering on large scales, weak gravitational lensing, galaxy-cluster abundance, and supernova distances. I will present the current status of the project, the some of the scientific results of the survey, and the plans and goals for the coming years.  I will also talk about the relevance and construction of mock galaxy catalogues for the analysis of galaxy clustering, including the current mocks being created for DES.
