Come in shinecharged from the top left door. With missiles selected, position Samus roughly in the horizontal center of the room. Crouch, hold angle up and angle down simultaneously to aim up, then in very quick succession, shoot a Missile upwards, release angle up and angle down, press and hold jump to initiate the shinespark wind-up from a crouch, then quickly press up to spark upwards. If done correctly, Samus will pass the Missile, break the bomb block platforms, then be passed by the Missile which will break the shot blocks at the top.

Initiating the shinespark from a stand can also work, but if no tanks are available, Samus will not get high enough reach the ledge normally and would have to down-back.
