Solar Dynamics Observatory hopes to bring better understanding of Sun’s influence on Earth

Scheduled for an upcoming winter launch is a new observatory to study the sun’s influence on Earth and the space around with the use of several instruments studying our star simultaneously on multiple wavelengths.

Just one of several upcoming missions to study the sun, the Solar Dynamics Observatory (SDO)’s goal is to better understand the energy that generates the suns magnetic field, and the energy used for the creation of solar winds, and other variations in solar activity.

SDO will measure the sun’s interior, its magnetic field, the plasmas of its solar corona, and other areas using 3 instruments. The Atmospheric Imaging Assembly which will image the sun’s atmosphere in multiple wavelengths, and compare data from sun’s interior. The Helioseismic and Magnetic Imager which will extend the capabilities and resolution of the SDO. And the Extreme Ultraviolet Variability Experiment which will measure the EUVs spectral irradiance to better understand the effects on the Earth’s Climate and Near-Earth space.

A February 3, 2010 launch date is the current target.
