SOLAR TERRESTRIAL RELATIONS OBSERVATORY (STEREO) MISSION

Photo: STEREO satellites in there orbit around EarthSTEREO (Solar TErrestrial RElations Observatory) is a 2-year mission employing two nearly identical observatories to provide 3-D measurements of the Sun to study the nature of coronal mass ejections. These powerful eruptions are a major source of the magnetic disruptions on Earth and a key component of space weather, which can greatly affect satellite operations, communications, power systems, the lives of humans in space, and global climate.
