Solar Dynamics Observatory (SDO) — •Markus Roth — Kiepenheuer-Institut für Sonnenphysik, Schöneckstr. 6, 79140 Freiburg, Germany

The Solar Dynamics Observatory (SDO) is the first mission to be launched for NASA's Living With a Star (LWS) Program. SDO is designed to help understanding the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small spatial and temporal scales in many wavelengths simultaneously. The mission is planned to be launched in early 2010, and carries three primary instruments on board: the Helioseismic and Magnetic Imager (HMI), the Atmospheric Imaging Assembly (AIA), and the Extreme Ultraviolet Variability Experiment (EVE). The recorded data of 1-2 TB per day will be predominantly used for studying the origins of solar activity and how Space Weather is related to that activity. Measurements of the interior of the Sun, the Sun's magnetic field, the hot plasma of the solar corona, and the irradiance that creates the ionospheres of the planets will contribute to achieve the goals of the mission. In my presentation I will describe the science objectives of SDO, the instruments on board, expected results and their potential impact on future solar research.
