Abstract: | The Eddington mission was given full approval by the European Space Agency on the 23rd May 2002, with launch scheduled for 2007/8. Its
science objectives are stellar evolution and asteroseismology, and planet finding. In its current design it consists of 4
× 60 cm folded Schmidt telescopes, each with 6o × 6o field of view and its own CCD array camera. Eddington will 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 field monitoring upwards of 100,000 stars for planet searching. The
asteroseismic goal is to be able to detect oscillations frequencies of stars with a precision 0.1–0.3 μHz, to probe their
interior structure and the study the physical processes that govern their evolution.
