Abstract

Discoveries in the last decades have stimulated the use of interdisciplinary tools to study exoplanets and, naturally, astrobiology. These efforts are helping to understand complex phenomena as, for instance, planetary habitability. Science is trying to answer ancient questions as: Are there planets similar to ours outside the solar system? Is life a common phenomenon in the universe? How life originated on Earth? What is the future of life on Earth? In this thematic project, we will study some open questions in the field of exoplanets and habitability. Brazil is participating in the development of science and engineering of ESA's Cosmic Vision program medium-class satellite PLATO 2.0 to be launched in 2024. PLATO main objective is to find and study a large number of extrasolar planetary systems, with emphasis on the properties of terrestrial planets in the habitable zone. The engineer aspect of this project comprises part of its payload design and development. Brazilian scientific community will have access to PLATO's scientific data in a pro-rata sharing with its partner countries. (AU)
