Overview: ARIEL, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, is a European Space Agency (ESA) M-class mission, with participation from NASA, to survey and characterize the atmospheres of 1000 exoplanets. ARIEL is a 1 m class telescope with 3 photometric channels and 3 spectroscopic channels covering continuously 0.5 to 0.78 microns in wavelengths. The goal of ARIEL is to survey ~1000 transiting exoplanets from gas giants to rocky planets in the hot to temperate zones of their host stars. ARIEL is expected to launch in 2029.
NASA-JPL is contributing to the ARIEL Mission with the CASE (Contribution to ARIEL Spectroscopy of Exoplanets, PI Mark Swain) which provides the optical and near-infrared (0.5 - 2 um) science capabilities and fine guidance sensors for ARIEL. IPAC is providing the processing environment and the US Data Archive for all ARIEL data.
