             abstract = "This paper describes a mission analysis process used to explore 
                         and assess mission feasibility of a CubeSat satellite class which 
                         main objective was to take images of the Amazon rainforest for 
                         later deforestation analysis. The presented process shows what 
                         could be expected, its limitations and how to improve its results. 
                         Some analyses were performed through simulations using Systems 
                         Tool Kit (STK) and General Mission Analysis Tool (GMAT) software. 
                         The process consists of lifetime, payload performance and 
                         CubeSat-ground station communication link analyses. The CubeSat 
                         parameters used for calculations and simulations came from 
                         specifications found on a commercial CubeSat website, while ground 
                         segment input parameters came from the Aeronautics Institute of 
                         Technologys (ITA) Ground Station specifications. It was assumed 
                         that orbit was not designable, thus orbital position parameters 
                         were derived from the International Space Stations (ISS) orbital 
                         elements, considering the in orbit injection will take place 
                         there. Then, January 1st, 2018, was aimlessly chosen to extract 
                         ISSs orbital parameters. Results show that the payload performance 
                         fulfills the mission objectives, however, limitations on the 
                         transmission data rate limit the number of pictures that can be 
                         sent from the CubeSat to the ground station making unfeasible to 
                         fulfill objectives. One solution for this limitation could be the 
                         use higher frequencies that allow transmit at higher data rate. 
                         However, this would require using the state-of-the-art 
                         transmission equipment and would increase the size of the CubeSat. 
                         Another solution could be to adjust mission objectives in order to 
                         reduce the area of interest. Results also showed that if the 
                         altitude of a CubeSat deployment from the ISS could be chosen, 
                         then, it is better to choose the highest altitude. This would 
                         increase the CubeSat lifetime (up to 2 months) and bring 
                         advantages for radio accesses affecting very little the payload
