Tier is basically the level of the mission. If you do the mission on mars or mercury it's tier 1, if you do the same kind of mission on sedna, or pluto the tier is higher.

The same goes for the level of the enemies. As vague numbers: on the earlier planets they are lv 1~10, that's tier 1. If they are lv 20~30 it's already tier 2.

Rotations are how long you stay on the mission. It gives you rewards every 5 minutes or every successful extraction or every 10 waves? well, each time it gives you a reward the rotation moves along. So if it's excavation, the first reward is from the A table, the second from the A too, the third from B, and 4th from C, then it starts again from A.

Even if the enemies go up in level the longer you stay in it, the tier stays the same as you entered the stage.

So a excavation on earth will always be tier 1 even if you spend 3 hours there and the enemies start to scale hard. You need to go to higher and tougher planets to drop Tier 2 or 3 relics.
