abstract = "The goal of this work is to measure the amount of radiation a
spacecraft receives once it leaves the sphere of influence of
Earth in a Low Thrust Orbit (LTO). The spacecraft crosses the Van
Allen belts many times during the transfer, in which particles
such as protons and electrons can damage the onboard electronic
equipment. Through mathematically modeling of the density of
particles from the belt in space, it was possible to integrate it
in time and compute the total dose of radiation absorbed by the
spacecraft according to the chosen trajectory. Therefore,
different trajectories were computed varying in eccentricity and
type of propulsion system, which gave the following final
parameters of interest: mission duration, fuel consumption, time
in Van Allen belts and total fluence of radiation absorbed. Using
an optimization algorithm, thousands of trajectories were tested
and the best ones with respect to the final parameters were given
as a table of results.",
