             abstract = "Nowadays satellites are essential to human society mainly on 
                         communication system and science study. The NanosatC-BR Space 
                         Weather Mission consists of an integrated program for space 
                         research and engineering development of space technologies through 
                         the integration of a CubeSat (a cubic shape satellite with 
                         10x10x10cm and weighting no more than 1 kg of mass), the first 
                         Brazilian scientific nanosatellite. The Mission Program was 
                         conceived at the Southern Regional Space Research Center, (CRS), 
                         from the Brazilian National Institute for Space Research INPE/MCT 
                         with the involvement of undergraduate students from the Federal 
                         University of Santa Maria UFSM. The NanosatC-BR has the scientific 
                         objective to monitor in real time the Geospace, the disturbances 
                         observed at Earths magnetosphere over the Brazilian Territory, for 
                         the determination of its effects on regions such as the South 
                         Atlantic Magnetic Anomaly (SAMA) an the Ionosphere Equatorial 
                         Electrojet. The SAMA is of great significance to satellites and 
                         other spacecraft by the fact that the communication among 
                         satellites and to the Earth are affected by interference or loss 
                         of signal and all electronic satellites systems can be exposed to 
                         damage when the satellite pass through this anomaly. The mission 
                         requires the development of scientific instrumentation and, 
                         simultaneously, the design, manufacturing, qualification, 
                         integration and launch of the nanosatellite. The CubeSat has 
                         several subsystems that support and maintain the payload and all 
                         systems functioning. The requirement of the Thermal Control 
                         Subsystem is due to the aggressive environment faced in space, 
                         because abrupt changes in temperature occur frequently and 
                         sensitive electronic devices must be properly protected to 
                         maintain its operating temperature range within the required 
                         limits. In order to provide a design which meets the temperature 
                         requirements of the spacecraft, we must account for heat inputs 
                         from the Sun, the Earth, and electrical and electronic components 
                         onboard the spacecraft. The thermal design of small satellites 
                         like the NanosatC-BR is restricted due to their size and 
                         availability of energy, so it is used only passive controls 
                         without the consumption of electrical energy. The design must 
                         comply with the limits of temperature variation inside the 
                         satellite, with all possible variables. Dedicated computer 
                         programs are used, working with advanced numerical methods, which 
                         provide a real view of the interaction of space with the satellite 
                         and the internal heat exchanges.",
