Exoplanet mission

Ariel (exoplanet mission)

The European Space Agency's Ariel is the first mission dedicated to surveying the atmospheres of a large, diverse sample of known exoplanets — around a thousand — chiefly by transmission and emission spectroscopy at infrared wavelengths. Selected as ESA's fourth medium-class mission and planned for launch in 2029, it aims to link atmospheric composition to how and where planets form.
