And how is this going to work on Moon and Mars?
Different designs.
Lunar HLS lander has legs and a reaction control system but no flaps - obviously.

Mars lander will probably resemble the HLS. Atmosphere is so thin flaps won’t help much, but reduced gravity means it will carry enough fuel for landing and take-off without flaps for additional aero braking.
