A pioneering mission in solar astronomy and space weather science passed a key milestone this week, as the Solar Heliospheric Observatory (SOHO) crossed an amazing 30 years in space.
SOHO has far exceeded its original 2-year nominal mission. The mission launched on December 2, 1995 from Cape Canaveral U.S. Air Force Station on an ATLAS IIAS rocket. SOHOβs vantage point parked in a Lissajous halo orbit around the sunward L1 Lagrange point a million miles (1.5 million kilometers) from Earth affords it an uninterrupted view of the Sun.
