There is a target area we want to land in order to investigate certain terrain or other POI's near the target.
It obviously can't land on mountains and certain rocky or steep terrain. They know its limitations. These limitations determine where it can or can't land.
During target selection they will find an adaquet place on the surface that meets the criteria.
By increasing from 500m^2 to 4000m^2 they need to find a larger area that meets those same needs.
This also helps during the actual landing. It can aim anywhere inside that 4000m^2 area instead of being limited to just a 500m^2 area.
oh I see, so it's not that they picked the same center and said "oh btw now you can land in a larger circle around it" but rather they picked a different site altogether? that makes a lot more sense, thanks
