After the discussion about the atmosphere and how to model the most relevant physical aspects, the moment has come to put a moving object into this atmosphere and find out how the two will interact with each other. After all, a lot has to happen between entering the atmosphere and landing on the surface of the planet below. To begin with, at entry the vehicle will have a large altitude and velocity, or in other words, potential and kinetic energy. This energy has to be “shed” before the vehicle can land at an acceptable speed. This could be achieved by using a propulsion system to brake, but this might be a very expensive way to do that. Alternatively, maybe in some way the atmosphere can be used. And indeed, the vehicle interaction with the atmosphere creates an aerodynamic force, which can be used to both decelerate the vehicle to an acceptable landing speed, and guide the vehicle towards a predefined landing location.
