The Galileo Solar Space Telescope (GSST) is a cutting-edge solar physics mission currently undergoing the Brazilian Space Agency (AEB) admission process. The primary objective of GSST is to investigate the magnetic field of the solar atmosphere and its profound influence on the evolution of the Heliosphere. Solar electromagnetic and corpuscular emissions are intricately linked to the magnetic structure of the solar atmosphere, which, in turn, is governed by the energy transport from the Sun's inner layers. Despite historical observations, there remains a need for a complete understanding of the physical processes governing solar activity cyclic variability and long-term changes. The GSST mission aims to shed light on fundamental physical and plasma processes within the Sun, such as the solar dynamo and the heating of the outer layers, encompassing the Chromosphere to the Corona. Moreover, the mission seeks to unravel the effects of the solar magnetic structure on Earth's atmosphere-ocean system and the broader Geospace environment. The GSST mission revolves around three main objectives: firstly, comprehending the intricate evolution of the Sun's magnetic structure; secondly, exploring the Sun's intricate influence on Earth's climate; and lastly, investigating the Sun's impact on the dynamic Geospace. To achieve its scientific goals, the mission will leverage the sophisticated multi-mission platform developed by the INPE. The payload of the GSST includes state-of-the-art spectropolarimeters targeting critical lines in the Chromosphere and surface, enabling high-resolution observations. Here, we will present a description of the recent advances in the project.
