A joint European Space Agency and NASA spacecraft launched in 1995 to a stable vantage point between the Sun and Earth, providing an uninterrupted view of the Sun for studying its interior structure, outer atmosphere and the solar wind it generates. Decades past its planned two-year mission, it remains a primary source of real-time solar imagery used for space weather forecasting.

Launch section
SOHO's launch, 2 December 1995
Orbit section
SOHO moves around the Sun on the sunward side of Earth, where it enjoys an uninterrupted view of the Sun, by slowly orbiting around Lagrange point L1.
Mission overview section
SOHO's studies range from the Sun's interior, its visible surface and stormy atmosphere, to where the solar wind blows in distant regions of our Solar System.
Orbit mechanics section
This a spot in space where the gravitational fields of the Sun and Earth cancel each other and keep SOHO in an orbit locked in line with the two bodies.
