Heroic quests on all planets are all repeatable per day - that should explain 50s on Voss and other near 50 planets - they often provide some nice rewards like mods and orange items, or maybe containers with random loot, who knows what people are up to there. Or maybe there are daily quests I'm not aware of myself.
