Launched on Feb. 11, 2010, SDO is the most advanced spacecraft ever designed to study the sun. During its five-year mission, it will examine the sun’s magnetic field and also provide a better understanding of the role the sun plays in Earth’s atmospheric chemistry and climate. Since launch, engineers have been conducting testing and verification of the spacecraft’s components. SDO will provide images with clarity 10 times better than high-definition television and will return more comprehensive science data faster than any other solar observing spacecraft.
