SOHO accidentIn 1998, contact was lost with the Solar and Heliospheric Observatory (SOHO). It was positioned in a "halo" orbit around L-1, a gravitational balance point between Earth and the Sun about 1.5 million km (930,000 mi) away from Earth. Fortunately, a major blow to the field of Solar studied was avoided. Contact was reestablished 16 Sep 1998, and by mid-October scientists were reactivating the science instruments. Since its launch on 2 Dec 1995, SOHO gave solar science a new ability to observe simultaneously the interior and atmosphere of the Sun, and particles in the solar wind and the heliosphere. Observation of eruptions of hot, electrically charged gas, provided early warning of interactions that could affect the Earth. |
