The Portal Access is a room in the Agon Wastes. The room connects Mining Station A to the Portal Terminal. There are two sides to the room, separated by a wall in the center. To go from one side to the other, Samus can use two Kinetic Orb Cannons on each side of the wall that form a sequence. One will shoot to the other, which will shoot to a higher ledge. From this ledge, Samus can roll to the other side of the wall. The west side of the room has a Luminoth corpse in it, along with a Missile Expansion in a small area next to the ground level cannon.
