How does STEREO fit into NASAs science program?
Heliophysics is one of the four principal science divisions within NASA’s Science Mission Directorate. Heliophysics focuses on explaining the physical processes that link the sun with the Earth and the rest of the solar system. STEREO is part of the Solar Terrestrial Probes (STP) Program which offers a continuous sequence of flexible, cost-capped missions designed to systematically study the sun-Earth system. Solar Terrestrial Probes missions focus on studying the sun and Earth as an integrated system using a blend of in situ and remote-sensing observations, often from multiple platforms. STEREO contributes to all three of the Heliophysics Division’s scientific objectives: (1) understanding the changing flow of energy and matter throughout the sun, heliosphere and planetary environments; (2) exploring the fundamental physical processes of space plasma systems; and (3) defining the origins and societal impacts of variability in the sun-Earth connection. STEREO is the third mission withi
