The Solar and Heliospheric Observatory or SOHO for short is a cooperative joint effort by the European Space Agency (ESA) and the U. S. National Aeronautics and Space Administration (NASA). The main mission of this project is to study the internal structure of the Sun, its extensive upper atmosphere, as well as to determine the origin and characteristics of the solar wind.

The SOHO spacecraft was launched on December 2, 1995 where then it was directed to go about 930,000 miles sunward from the Earth to the L1 or the Lagrangian point. This "Lagrangian" point is a place between the Sun and the Earth where the gravity pulls of both masses stabilize the spacecraft enough to achieve a state of gravitational equilibrium between the two masses. At this point, the spacecraft then established its own "halo-like" orbit in space but continued to also orbit about the Sun in the same orbital path as the Earth. Once SOHO's "halo-like" orbit was established, the spacecraft was then ready......
