The lander module would do two things.
1. Gyro function that causes the ship to always rotate towards being level with the planet.
2. Be the parent system for landing thrusters/hover modules, whose sole purpose is to keep you hovering and not drop like that unfortunate whale in Hitch hikers guid to the galaxy. The bigger the mass, the more thrusters/hover modules are needed.
