CHEOPS in Italy

 
 

CHEOPS (CHaracterizing ExOPlanet Satellite) has been proposed as an S-class mission in response to the call for Proposals issued by ESA in March 2012. It has been selected by ESA as the first S-class mission in Cosmic Vision 2015-2025. The mission has been adopted in 2014, with launch planned for early 2019.

The CHEOPS mission is a joint ESA-Switzerland project, with important contribution from Italy and a number of other ESA Member States, cooperating within a dedicated Mission Consortium.

CHEOPS is the first mission dedicated to the characterization of small-size transiting planets by means of ultrahigh precision photometry on bright stars already known to host planets. It will allow an accurate determination of the radii of transiting planets, for which the mass has already been measured from ground-based spectroscopic surveys. It will also provide precision radii for new planets discovered by the next generation of ground-based transits surveys (Neptune-size and smaller).

For the first time, CHEOPS will enable comparative planetology in an unexplored mass range at a precision never before achieved. 

CHEOPS will provide, in a very timely way, unique targets for future ground- (e.g. E-ELT) and space-based (e.g. JWST, EChO) facilities with spectroscopic capabilities for atmospheric characterization. With well-determined radii and masses, the CHEOPS planets will constitute the best target sample within the solar neighborhood for such future studies.

 

CHEOPS at a Glance

CHEOPS (CHaracterizing ExOPlanet Satellite) has been proposed as an S-class mission in response to the call for Proposals issued by ESA in March 2012.

It has been selected by ESA as the first S-class mission in Cosmic Vision 2015-2025 for a launch in 2017.

CHEOPS primary goal is characterizing transiting exoplanets on known bright and nearby host stars.

Italy is one of the partners of the Consortium developing the CHEOPS satellite. CHEOPS in Italy is made by the collaborative efforts of INAF, UniPD, and ASI.  This is the web site of the CHEOPS Italian Team.
