Abstract
Since the ending of the Space Shuttle Program, the National Aeronautic Space Administration (NASA) has embarked in ambitions projects for the conquest of space. Nowadays going to Mars and beyond are high new goals. NASA’s Morpheus Project requires the development of a new planetary lander that can go to the Moon, to Asteroids or other Planets. At this stage most planned proposals are unmanned intelligent and autonomous vehicles. Study of the stability and the fuel consumption are goals within the scope of this research. Due to the changing mass of the vehicle because of fuel consumption the development of computer models is required to predict how the vehicle will operate autonomously in space making decisions based on the circumstances.
