Contribution to ARIEL Spectroscopy of Exoplanets (CASE) is a detector subsystem contribution to an infrared spectrometer instrument for the planned European ARIEL space telescope. It is being developed by NASA as a contribution to the European Space Agency (ESA) project to add scientific capabilities to the space telescope to observe the chemical composition of the atmospheres of exoplanets,[1] as well exoplanetary metallicities.[1][2] The ARIEL spacecraft with CASE on board is planned to launch in 2029.
