The ASEPS program will survey hundreds of thousands of stars with V 8-13 in the solar neighborhood using the wide-field Sloan 2.5 meter telescope. Following up all the candidate planetary systems with visible and near infrared radial velocity instruments could result in detecting thousands of planets, including rare planetary systems such as transit planets, ``super-Earth'' mass planets, and interacting multiple planetary systems, during 2006-2020. ASEPS will provide a valuable statistical sample for studying many aspects of the formation and evolution of planetary systems. The overall ASEPS program has four major phases: a feasibility study and demonstration in 2004-2005 (phase I), a trial survey and a pilot program in 2005-2008 (phase II), a full-scale planet survey in 2008-2013 (phase III) and an extended survey from 2013-2020 (phase IV). During 2006, we commissioned a full-scale multi-object W.M. Keck Exoplanet Tracker (Keck ET) with 60 object capability and began a trial planet survey of 400 stars at the Sloan telescope. Since August 2006, we have substantially improved the instrument performance (throughput, image quality, Doppler precision and long term stability. In fall 2006, we began searching additional stars. I will summarize the status of ASEPS, early results, and the project's future prospects.
