The SOHO (Solar & Heliospheric Observatory) project is being carried out by the
European Space Agency (ESA) and the US National Aeronautics and Space
Administration (NASA) as a cooperative effort
... between the two agencies in the
framework of the Solar Terrestrial Science Program (STSP) comprising SOHO and
CLUSTER, and the International Solar-Terrestrial Physics Program (ISTP), with
Geotail (ISAS-Japan), Wind, and Polar.
SOHO was launched on December 2, 1995. The SOHO spacecraft was
built in Europe by an industry team led by Matra, and
instruments were provided by European and American
scientists. There are nine European Principal Investigators
(PI's) and three American ones. Large engineering teams and more
than 200 co-investigators from many institutions supported the
PI's in the development of the instruments and in the
preparation of their operations and data analysis. NASA was
responsible for the launch and is now responsible for mission
operations. Large radio dishes around the world which form
NASA's Deep Space Network are used to track the spacecraft
beyond the Earth's orbit. Mission control is based at Goddard
Space Flight Center in Maryland.
