Controlling the Eccentricity of Polar Lunar Orbits with Low-Thrust Propulsion
Figure 1
Sample of the satellite's orbital evolution in a diagram e versus w. There are two sets of initial values of eccentricity and inclination One for low inclination, 0° (thick lines) and other for high inclination, 6.2°, (thin lines). The values of the initial eccentricities are represented by the colour code in the bottom of the figure. The argument of pericentre circulates in the case of initial low inclination, while librates in the case of initial high inclination.
