Larceny missions plus SC reset is the way to go. Land, jump out, cut open all the containers, loot everything and the kitchen sink EXCEPT the mission target, get back to ship, launch, point up, jump to sc, immediately turn around, rinse, repeat. You can do that until you get sick of it, then take the mission target and be done with it. This is also the way to go if your mission target won't spawn at all, or is inaccessible due to "buried" containers.
Sometimes you will find scavengers there at first, so take dumb-fire missiles with you and nuke them from orbit.
