The NANOSATC-BR1 and NANOSATC-BR2 are the first and the second satellite, respectively. They belonged to the project NANOSATC-BR-development of CubeSats, which is performed in the facilities built by the partnership between the National Institute of Space Research and the Technological Center from Federal University of Santa Maria. The project focuses on the development of a scientific instrumentation and, simultaneously, the design development, construction, qualification and launch of a national scientific nanosatellite, in a cube shape with 100 mm of edge and near to 1.33 kg of mass, per unit （U）. The risk analysis was held to identify and minimize the project＇s risks of failure, due to its complexity, assuring the mission success, preventing extra pays and rework. The software, CubeSat Mission Design Software Tool for Risk Estimating, which uses statistical regression methods, was used. So, we were capable to measure the project＇s most critical steps assuring its success. The NANOSATC-BR1 was launched in June 19 and it is orbiting the Earth in a nominal regime and the NANOSATC-BR2 has been scheduled to be launched in 2016.展开更多
