             abstract = "Here we present the concept feasibility study of the Galileo Solar 
                         Space Telescope Mission (GSST Mission) proposed by the Space 
                         Geophysics Division (DIDGE) of the Brazilians National Institute 
                         for Space Research (INPE). The study was conducted at the Space 
                         Missions Integrated Design Center (CPRIME - Centro de Projeto 
                         Integrado de Miss{\~o}es Espaciais) of INPEs Space System 
                         Division (DIDSE). The GSST shall contribute to the understanding 
                         of the evolution of the magnetic structure in the outer layers of 
                         the Sun and its influence on the Earths space environment. The 
                         scientific observations requirements proposed for the mission 
                         include high spatial and temporal resolution observations. Those 
                         measurements involve observations of the magnetic structure of the 
                         photosphere and outer layers of the solar atmosphere through the 
                         solar cycle, observations of the variability of the total solar 
                         irradiance, and in situ observations of magnetic field and high 
                         energy particle fluxes within the Earths magnetosphere. The 
                         concept feasibility study, which was carried out during the second 
                         half of 2017, included: (a) the definition of the scientific 
                         objectives, requirements and restrictions of the mission; (b) the 
                         identification of the system drivers; (c) the definition of the 
                         candidate solutions for the system; (d) the conceptual design of 
                         the missions architecture components, including the optical 
                         payloads; (e) the pointing accuracy analysis of the designed 
                         attitude control subsystem; (f) the simulation and verification of 
                         the mission operational concept; (g) the assessment of the ground 
                         segment required to fulfill the mission; (h) estimate of the 
                         schedule for the development of the mission; and (i) the risk 
                         analysis. The optical payload architecture, orbit and ground 
                         segment were identified as the main system drivers. The concept of 
                         two full disk telescopes and one highresolution telescope for 
                         visible and ultraviolet spectropolarimetric observations have been 
                         the bases for the solution of the optical payload architecture 
                         selected for the scientific purposes. Foroptimizing the solar 
                         visibility and the data downlink, the study has considered two 
                         orbits as possible: a sun-synchronous Low Earth Orbit (LEO), and a 
                         Geosynchronous Orbit (GEO). Each solution implies an exclusive 
                         spacecraft layout development. We point out that the cost analysis 
                         is still preliminary due to the lack of a similar mission in INPEs 
                         portfolio. Finally, the limitations of the concept and future 
                         strategies to implement such mission in a challenging funding 
                         environment as the current Brazilian scenario shall be 
                         addressed.",
