Freeze two Mochtroids above the door to set up a moonfall between them, and aim down. After gaining enough speed, press forward to fall down and clip past the door shell below. Falling with too much speed can cause Samus to go out of bounds. Gravity Suit is needed in order to gain enough fall speed before the Mochtroids thaw.

Requires:

"Gravity"
"canEnemyStuckMoonfall"
"canTrickyUseFrozenEnemies"

Bypasses door shell: true
