The Eddington mission was given full approval by the European Space Agency on the 23rd May 2002, as part of the new “Cosmic Vision” Science programme, with launch scheduled for 2007. Its twin science objectives are asteroseismology and planet finding. In its current design it consists of 4 × 60 cm folded Schmidt telescopes, each with 5° × 5° field of view and its own CCD array camera. The current observing plan is to spend 2 years primarily devoted to asteroseismology with 1–3 months on different target fields monitoring up to 50,000 stars per field, and 3 years continuously on a single target field monitoring upwards of 100,000 stars as required for planet searching. The asteroseismic goal is to be able to detect oscillations frequencies with a precision 0.1–0.3 μHz.
