ESA/ESTEC, Noordwijk, THE NETHERLANDS, 14-16 JANUARY 2020
Ariel is the first space mission dedicated to measuring the chemical composition and thermal structures of a large diverse sample of transiting and eclipsing exoplanets, enabling planetary science far beyond the boundaries of the Solar System.
Ariel (then ARIEL) was selected as M4, the fourth medium-sized (M class) mission in ESA's Cosmic Vision Plan, in March 2018. At the time of the conference the mission was in the definition study phase (phase B1), with the next major milestone being mission adoption by the ESA Science Programme Commttee foreseen for November 2020. Ariel has been formally adopted by the SPC on 12 November 2020.
This conference was attended by about 200 participants from 19 countries and had the objectives to:
- Involve the planetary and astrophysical community at large in the mission
- Present the mission and its science as proposed for mission adoption
- Put it into context of other missions and observatories
- Discuss and plan the best ways to promote long term community involvement
WORKSHOP Generalities
- Science programme, talks and posters
