A Sand Drain function is present in the Sand Processing room of the Space Pirate mining facility.
On her first pass through this room, Samus finds a large mound of sand on the floor, which acts as a platform for her if she chooses to backtrack, as the Sand Processing room is curved in a U-shape.
Later, after acquiring the Boost Ball, Samus can return to the room and use the floor of the room, which is a Half-pipe, to reach a small alcove on the far-right side. Through a tunnel here, Samus will reach an observation area containing a Bomb Slot. If she activates it, the sand in the room will drain through a grate in the floor. A Missile Expansion is then revealed, and Samus can exit the observation window and collect it.
