The Solar Dynamics Observatory will rely on three advanced science instruments to meet the mission's goals. The Atmospheric Imaging Assembly, an array of four telescopes, will observe the solar surface and atmosphere. The Extreme Ultraviolet Variability Experiment will measure changes in the amount of ultraviolet light the sun emits. Finally, the Helioseismic and Magnetic Imager will create maps of the sun's magnetic fields and look past the sun's surface.
