  • A French CNES mission with European partners & Brazil [+ S. Aigrain, T. Mazeh, A. Shporer]27cm telescope with polar orbitJoint stellar seismology & exoplanets transits missionLaunched on 12 / 27 / 2006

    5 fields of 4 square degrees observed, including two for ~150 days at ~mid-term of the mission.~30,000 dwarf stars observed between 11 < Vmag < 16Photometric data is gathered in a mask of pixelsThe CoRoT Satellite
