Abstract: Mars Rovers are the unmanned machines on planet MARS which are send to analyze and provide details about the planet. GPU and Genetic Algorithms are upcoming technologies used in Mars Rovers for analyzing and sending the data back to the Earth base station. GPU stands for Graphics Processing Unit in which Image compression is the basic layout of the technology. Image compression involves WAVELET transform and Image segmentation involves genetic algorithm. This paper focuses on introducing the GPU technology and Genetic algorithm and methods involved in it which are key for space communication in the near future.
