The Transfer Element for the piloted lunar lander

Unlike the "classic" two-stage designs from the Moon Race era, the crew lander based at the cis-lunar Gateway will need a third element. Because the trip from the very high lunar orbit of the proposed station will require a considerable "push" to reach the low orbit around the Moon before the final braking and descent to the surface could begin, it would not be practical to carry all the necessary propellant for the maneuvers aboard a single descent stage. Hence, the addition of a transfer space tug.
