             abstract = ": One of the major concerns these days, in relation to the space 
                         segment, is the mitigation of waste from missions that have 
                         reached the end of their useful lives. The density of space 
                         debris, located primarily in Low Earth Orbits (LEO), is growing 
                         exponentially, making the space agencies around the world develop 
                         policies to minimize these wastes. Within this perspective, the 
                         objective of this work is to develop a thorough study of the 
                         mitigation of space debris, coming from the nano-satellite 
                         constellation for environmental data collection of the CONASAT 
                         project, which is being developed by the National Institute for 
                         Space Research - Northeast Regional Center (CRN-INPE), in 
                         partnership with the Brazilian Space Agency (AEB), seeking a 
                         solution for the Brazilian System of Environmental Data Collection 
                         based in nanosatellites. The orientation of the project follows 
                         the rules of the European Cooperation for Space Standardization 
                         (ECSS) and the mitigation of space debris follows the European 
                         Code of Conduct for Space Debris Mitigation, of June 2004, which 
                         foresees a maximum decay time either natural or forced, of 25 
                         years after the lifetime of the mission. Within this perspective, 
                         considering a natural decay due to restrictions of engineering and 
                         safety and a lifetime of approximately two years, this study 
                         analyzes several satellite configurations, evaluating different 
                         geometric shapes, masses and altitudes that enable compliance with 
                         the European Code of Conduct for Space Debris Mitigation as well 
                         as the objectives proposed by the mission. The study was conducted 
                         with the aid of several computational tools, including MATLAB, for 
                         the analysis of the relationship between areas and masses of the 
                         satellites, the Satellite Tool Kit (STK) for the analysis of the 
                         orbital parameters involved and the Debris Assessment Software 
                         (DAS) the latter supplied by the National Aeronautics and Space 
                         Administration (NASA) and used for computation of the decay time. 
                         As a result, the work will provide data that will serve as 
                         reference for defining the constructive aspects of the 
                         constellation of the satellites, in regards to geometric and mass 
                         limits as well as their orbital aspects.",
