COROT (COnvection and ROtation stellar and planetary TRansits) is a mission mainly led by CNES aiming at seismic observations of stars and the search for exoplanets. It was launched at the end of 2006 from Baikonur on a low polar Earth orbit for an initial duration of 3 years. It has finally been operated until the end of 2013 and scientific exploitation continues.
The Sun and its corona as seen by HECOR and HEIT: preliminary results
Launched on September 14, 2009 from White Sands Missile Range (New Mexico), the Herschel sounding rocket was carrying two experiments with strong IAS participation: HECOR and HEIT.
PICARD is a survey on the simultaneous measurement of the absolute total and spectral solar irradiance, solar diameter and shape, and the interior of the Sun by helioseismologic survey.
These measurements obtained throughout the mission will enable study of their variations as a function of solar activity.

STEREO (Solar TErrestrial Relations Observatory) is a NASA mission composed of two nearly identical spacecraft that provide us with unprecedented three dimensional views of our Sun. STEREO was successfullly lauched by a Delta II rocket on October 25, 2006 at 8:52pm EDT from Cape Canaveral in Florida.
PLATO (PLAnetary Transits and Oscillations of stars) a été sélectionnée comme mission M3 du programme Cosmic Vision de l'ESA. Le lancement est prévu en 2026. Son but est de décrire les systèmes stellaires observés et d'en caractériser les planètes.
L'équipe sera fortement impliquée dans le segment sol (ainsi que dans l'analyse scientifique).
