Lure an Atomic or get a Covern to spawn to extend the runway. Position the enemy horizontally centered in the hole to extend the runway all the way to the wall. Positioning a Covern is tricky. One way to set this up is with Space Jump. Align Samus left against the tile in the ceiling to align the Covern horizontally, then perform short Space Jumps half way between the desired Covern position and the ceiling until the Covern spawns in the correct position.
