Rocket Launch Of Stereo Satellite
STEREO consists of two spacecraft that together comprise the first mission to take measurements of the sun and solar wind in 3-D. This new view improved our understanding of space weather and its impact on the Earth. During the two-year mission, the nearly identical spacecraft explored the origin, evolution and interplanetary consequences of coronal mass ejections, the most violent explosions in our solar system. When directed at Earth, these billion-ton eruptions can disrupt satellites, radio communications and power systems. In addition, energetic particles associated with these solar eruptions are hazardous to scientific spacecraft and astronauts.10/25/2006 Rocket Launch.
