ARIEL is the first space mission dedicated to measuring the chemical composition and thermal structures of a large well constructed sample of transiting and eclipsing exoplanets, enabling planetary science far beyond the boundaries of the Solar System.

The science objectives of ARIEL as selected in 2018 are described in detail in the Yellow Book, and more recently in 'A chemical survey of exoplanets with ARIEL' by Tinetti et al. Exp. Astron. 46:135, 2018 - (open access).

The science objectives of ARIEL as proposed for adoption in 2020 will be an updated and consolidated version of that of the mission as selected. They will be described in detail in the Red Book, which is anticipated to become available in the summer 2020 timeframe (see further on the Documents and Articles webpage).

Consider attending the ARIEL Science, Mission & Community 2020 conference to be held on 14-16 January 2020 in ESA/ESTEC, Noordwijk, The Netherlands to learn the latest on all aspects of the ARIEL mission, including of course the science.
