The extended strategy EDVEGA (Electric Delta-VEGA) is presented. What is stressed is the use of 1.4-year singular trajectory that preserves the encounter period with the Earth regardless of how much delta-V excess is garnered and embedded. The biggest advantage is, first of all, that the electric propulsion is performed efficiently at 1 AU distance. The other advantages are that the Earth launch C3 can be reduced to zero and the declination angle constraint is avoided. Some analytic efficiency evaluation method and numerical examination are carried out. The strategy can be widely applied for the outer space explorations.
