Rover's Lander

Rover's Lander is a building that places a Rover onto a planetoid surface. It functions by deploying a Rover from orbit down to a planetoid whenever a Rover's Module is present in that orbit. In gameplay terms, the Lander acts as the ground-side delivery mechanism for Rovers: its sole purpose is to receive a Rover from orbit and set it down on the target planetoid.

The Lander only operates when there is a Rover's Module located in the planetoid's orbit. If no Rover's Module is currently in orbit, the Lander does not perform a deployment. Conversely, when the Rover's Module is in the appropriate orbit, the Lander will deorbit and place the Rover onto the planetoid surface.

Practical considerations and usage notes:

• Deployment condition: the presence of a Rover's Module in orbit is the required condition for the Lander to deliver a Rover to the planetoid. Plan and coordinate orbital assets accordingly.
• Role in expedition workflow: use the Lander as the endpoint of an orbital-to-surface transfer. The Rover's Module supplies the in-orbit Rover, and the Lander receives and sets it down.
• Targeting: the Lander is tied to the planetoid it occupies; it deploys Rovers onto that planetoid when the corresponding Rover's Module is in that planetoid's orbit.
• Activation is deterministic: given a Rover's Module in orbit, the Lander will perform the landing operation; without that module, no landing occurs.
• Integration with base operations: position and prepare the Lander on the intended planetoid surface before expecting a Rover delivery; ensure orbital scheduling places a Rover's Module in the same orbit.

This building serves as the bridge between orbiting Rover delivery systems and on-surface Rover operation, enabling players to bring Rovers from space down to specific planetoids for exploration, resource gathering, or other surface tasks.
