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.
IAS is directly involved in the mission at various levels:
-design and realisation of an optical sub-system (imaging prism for the exoplanet channel),
-involvment in operation and data treatments in order to reach the required photometric precision,
-data archiving and distribution.
