During that trek, which we usually never have to take since we can land right next to targets, I actually got in some exploring and scanning, and gathered some resources I need. Something that basically never gets done because it requires going out of your way to land on planets in random locations. 2.5km may be more than most might want to walk, but I feel like a shorter hike to your mission target is just what the game needs to make use of its planetary surfaces.
