1. Mission № 2 is the most effective. 2. Mission № 6 is a bit less than mission №2 by effective. Used only unmanned vehicles in the mission № 6. 3. In missions № 6-8 use reusable ascent-descent vehicles, which make a few cycles "landing on lunar surface - ascent to lunar orbit". Vehicles are served and refueled by crew from Tug. The missions are the more effective then missions with one-time lunar ascent-descent means. That could be explaining by presence the mass of load for logistic securing from Earth associated with reusable space vehicle. In the future, when possibility will appear to get a fuel for space vehicles on Moon, necessity to delivery fuel from Earth will be smaller. By this reason the effectiveness of the missions will increase as compared with the missions where use one-time vehicles. The characteristic of the mass of load for logistic securing from Earth has different reaction on the index of effectiveness of mission as a whole - in dependence from the phase of lunar exploration.
