Fueled by advances in software, computation, microelectronics, and large optics fabrication, a new type of sky survey will soon begin. In a relentless campaign of 30 second exposures, the Large Synoptic Survey Telescope will cover the sky deeply in six bands 0.3 – 1.1 micron every week for ten years, opening a movie-like window on objects that change or move on rapid timescales. The deep images from the LSST will chart billions of remote galaxies in 4-D, providing multiple interlocking probes of the mysterious Dark Matter and Dark Energy. In a high dimensional database, hundreds of petabytes will be mined and compared with Exascale simulations.
