Thrust program called perigee propulsion which minimizes gravity loss is analyzed; thrust is applied intermittently in regions of high velocity (near successive perigees); increased energy addition efficiency yields mass ratios approaching those for impulsive velocity change; application and operational aspects of perigee propulsion.
