About the STEREO Mission
STEREO (Solar TErrestrial RElations Observatory) is the third mission in NASA's Solar
Terrestrial Probes program (STP).
It employs two nearly identical space-based observatories - one ahead
of Earth in its orbit, the other trailing behind - to provide the first-ever stereoscopic
measurements to study the Sun and the nature of its coronal mass ejections, or CMEs.
STEREO's scientific objectives are to:
- Understand the causes and mechanisms of coronal mass ejection (CME)
- Characterize the propagation of CMEs through the heliosphere.
- Discover the mechanisms and sites of energetic particle acceleration
in the low corona and the interplanetary medium.
- Improve the determination of the structure of the ambient solar wind.
