Your Exo-suit is the only thing protecting you from the harsh environments of the planets you visit, and it's expanding pockets are the method by which you can transport materials to a greater degree. Blueprints can be found that will upgrade the available space for materials each individual space, as well as your life support and weather resistance systems. These systems will be difficult to implement without additional inventory slots, and to gain them you have to search for drop pods or use your Atlas Key V1 at each space station you come across and unlock the adjacent door. In there, you will find an inventory upgrade system.
