Plato, Cheops and Ariel

How It Works - - GLOBAL EYE -

The Plato tele­scope will build on the data col­lected from the up­com­ing Cheops (Char­ac­ter­is­ing Ex­o­planet Satel­lite) mis­sion, which is due to launch in 2019. Cheops will be the first mis­sion to use ul­tra-high-pre­ci­sion pho­tom­e­try to study so­lar sys­tems that are al­ready known to have plan­ets. In par­tic­u­lar, it will look for su­per-earths and Nep­tune-like worlds. Plato will be fol­lowed in 2028 by the Ariel (At­mo­spheric Re­mote-sens­ing In­frared Ex­o­planet Large-sur­vey) mis­sion, which will study the at­mos­pheres of around 1,000 dif­fer­ent ex­o­planet tar­gets. Its goal will be to find out what these worlds are made of and how they evolved. All three mis­sions will im­prove our cur­rent un­der­stand­ing of other worlds out­side our own cos­mic neigh­bour­hood.
