The Solar Dynamics Observatory (SDO) is ready to launch! The mission will be launced on February 9th, 2010, from Goddard Space Flight Center. SDO will ride a rocket into orbit and begin a new era in Heliophysics, the study of our sun and its effects on Earth and the solar system.
SDO is the first mission to be launched for NASA's Living With a Star (LWS) Program, a program designed to understand the causes of solar variability and its impacts on Earth. SDO is designed to help us understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.
SDO will help us to understand the how and why of the Sun's magnetic changes. It will determine how the magnetic field is generated and structured, and how the stored magnetic energy is released into the heliosphere and geospace. SDO data and analysis will also help us develop the ability to predict the solar variations that influence life on Earth and humanity's technological systems.
SDO will measure the properties of the Sun and solar activity. (read more)
