My Pod of Four to the Lunar South Pole

On my Lunar South Pole expedition I would take four people, because the spaceship can only fit four. First is a pilot to fly us. Second is a bioengineer to study the moon and to figure out a way to make oxygen and purify the frozen water. Third is an astrophysicist because they have knowledge about the moon and space. Fourth is a geologist to study under the Moon’s surface. They should be calm and even-tempered. I would leave behind solar powered batteries because there are 200 days of sun. Whoever comes next will have an unlimited supply of power.
