Comme pour de nombreux domaines de l'astrophysique on attend beaucoup de la mise en service de JWST en 2019 pour l'étude du Système Solaire. Je rappellerai rapidement les capacités instrumentales de JWST et mentionnerai ses avantages et limites pour l'étude des objets du système solaire. J'illustrerai ensuite quelques programmes scientifiques possibles en planétologie (Titan, objets transneptuniens, comètes).

The Sun’s activity exhibits a variety of transient phenomena which interact with the ambient solar wind and affect its global structure. In addition, they may impinge on Earth and on the planets of the solar system and modify their environment. The effects of solar events on the geospace and more generally in the heliosphere is one the questions that will be addressed by the mission Solar Orbiter, scheduled for launch in 2018, and combining remote sensing and in situ observations.
