STEREO

Solar TErrestrial RElations Observatory, is a NASA mission, that includes two twin satellites in orbit around the Sun, one preceding the Earth in its revolution around our star (Stereo-A) and the other following it (Stereo-B). This vision from two different points in space provided the first 3-dimensional images of solar flares and their interactions with the interplanetary medium. For this, the two satellites embarked the same instruments that consist in a set of imagers (coronagraphs, white light imagers,...) and in situ instruments to measure particles in various energy ranges and electromagnetic fields.
French participation, supported by CNES, was illustrated by the involvement of French laboratories, which contributed to the production of some instruments. LESIA was the principal investigator of SWAVES, IAS and Institute of Optics Graduate School participated in SECCHI. IRAP has developed IMPACT detectors. The IAS is also involved in data analysis
