ESA satellites SMILE and THESEUS

Abstract

SMILE is a space mission which aims to measure Earth's global system responses to solar wind and geomagnetic variations with innovative instrumentation, e.g. wide--field X-ray telescope of Lobster--Eye type, on board. It is a collaborative project of the European Space Agency and the Chinese Academy of Sciences. Transient High-Energy Sky and Early Universe Surveyor (THESEUS) is a space mission proposal accepted by the European Space Agency for a phase A study that would study gamma-ray bursts and X--rays for investigating the early universe and for the multi--messenger astrophysics. It involves a Lobster--Eye X--ray telescope as well. The SMILE and THESEUS international consortia involve the Czech Technical University in Prague and the Czech teams are expected to contribute to the projects, mainly to the X--ray telescopes and related science and software. }
