Optimization of the SD2 memory system

Abstract

As far as is evidenced, man has sought the answers to his deepest questions by observing the sky. The findings and studies that have been made in this way have helped us know the planet where we live and our situation in the universe. From Greeks to now, through Galileo, Kepler or the Hubble telescope, look out was key to better know the Earth. The Rosseta Mission is the best example of this strategy. It is know that there are comets that have similar features with the Earth at its younger phase. So, the goal of the mission is to land on a comet surface and make a study about its composition and properties. In this way it could be increased the knowledge about how was the Earth, and furthermore, what were the conditions that allowed the emergence of life on it. The objective of this project is work on the optimization of one subsystem of this mission. It is known that the space missions have all their resources optimized in order to reach their goals (the power consumption, the heat, the memory, etc.). So, in that case, it is important to work on the optimization of the memory consumption of the SD2 subsystem.
