Abstract :
To achieve the minimal fuel consumption, the Pontryagin maximum principle is utilized to generate an optimal guidance law for the whole process of the lunar probe´s soft landing which starts off from the perilune. It is shown that the singularity condition can not hold along an optimal trajectory on any closed time interval.
