Due to the crumble blocks, you'll need to come in from the top door to collect the missile. Shoot the shot block, use Screw Attack on the far left side to destroy the bomb block, then morph in and collect the missile. Coming out, be sure not to fall through the crumble blocks, and exit back through the top door.
