Temple Assembly Site

Video of getting the early Missile Expansion
Discovered by Frozen Mr. Toastbrot.
You can get the Missile Expansion in Temple Assembly Site before the main Missile Launcher (right after losing your items). The trick is to jump onto the leftmost small pillar when you enter the room from Collapsed Tunnel. You need to use the small slope on the ledge in front of the pillar to Ghetto Jump. It also seems to help if you start the jump a bit right of the crack in the slope (see this sketch). To get onto the pillar, you need to hit its broken edge and use it to push yourself up (see another sketch). Once on the pillar, jump onto the platform left of it and proceed to get the Missile Expansion.
