I have some doubts. I have for instance once figured out, how much fuel is required for landing of the lunar lander 'Eagle' and how much the return ascend would require, to catch up with the orbiter. My calculation showed, that the lander had enough fuel to decelerate from orbit velocity to zero velocity in respect to the Moon and to safely sink with stop at zero sinking velocity at the surface. But obviously the lander had to do the opposite, too. This would require ascent from the surface and acceleration to orbit velocity (to catch up with the orbiter). Besides the formidable difficulty of this rendezvous in the middle of nowhere, it also required more fuel the ascent stage could carry. That fuel was also necessary for the descent phase. So, in my opinion, they could not do it with such a craft. But if they have been on the Moon, they must have used something else: the 'Haunebu' (for instance). TH
