A typical Apollo lunar descent and landing maneuver started with a transfer from an initial circular lunar orbit at an altitude of 100km above the Moon”s surface to an elliptical entry orbit at its apolune by means of a finite thrust as shown in Fig. 2.1 of the Apollo \(12's\) maneuver design [1]. The insertion into an approximately \(15.3\,\textrm{km} \times 100 \,\textrm{km}\) elliptical transfer orbit was a common maneuver in the sequence of maneuver operations in all Apollo missions (see Fig. 2.2).
