SOHO

The SOlar and Heliospheric Observatory

The joint NASA / ESA spacecraft SOHO (Solar and Heliospheric Observatory) was launched on 2 December 1995 at 0808 UT (0308 EST) from the Kennedy Space Center, Cape Canaveral, Florida.
SOHO is designed to study the internal structure of the Sun, its extensive outer atmosphere and the origin of the solar wind, the stream of highly ionized gas that blows continuously outward through the Solar System. The view of the Sun is achieved by operating SOHO from a permanent vantage point 1.5 million kilometers sunward of the Earth in a halo orbit around the L1 Lagrangian point.
