Description
SOHO is a joint ESA and NASA solar observatory that studies the Sun from its deep interior through the visible surface, corona, and solar wind. Its uninterrupted view from the Sun-Earth L1 region also supports space-weather monitoring and an exceptionally productive search for sungrazing comets.
Launch Site
Outcome
SOHO remains active after three decades, greatly exceeding its original two-year mission. It has built a long record of solar structure and activity, supported operational space-weather forecasting, and discovered more than five thousand comets.
