Duty officers can be sent out on assignments which take anywhere between 15 minutes to 5 days (real time, not gameplay time). Assignments require a variety of input items, including a selection of available duty officers/civilians, energy credits, commodities, Tribbles, etc. At the end of the assignment, players may be awarded with combinations of XP, duty officers/civilians, energy credits, commodities, Tribbles, ship/personal equipments, etc. - depending on the outcome of the assignment.

By default there can be a maximum of 20 assignments running at the same time.[1] Up to three additional assignment slots can be purchased from the Fleet Embassy, once they have been unlocked.

Assignments can be split into two major categories:

The time remaining for a refresh can be seen on the bottom left of your Assignments window.

Assignment Rarity[ | ]

Common

  • Lowest rewards per mission time and input items

Uncommon

  • Higher rewards for same/similar inputs as common assignments
  • Can be identified by a Green tint on the assignment snapshot and One Bar on the lower left corner

Rare

  • Very high rewards for the same/similar inputs as other assignments
  • Can be identified by a Blue tint on the assignment snapshot and Two Bars on the lower left corner

Very Rare

  • Highest rewards for the same/similar inputs as other assignments
  • Can be identified by a Purple tint on the assignment snapshot and Three Bars on the lower left corner
Note that the rarity of the duty officer assignments reflects the chance to spawn in assignments list but not always how frequently/often is received .
For example Assignment: Prepare Baked Tribble for Captain has a Common rarity with 1h duration but the chance to receive that assignment again is approximately after 2 days which makes it rare somehow (maybe because of the reward type/quality too).
So the assignments may have an internal server clock/cool-down. After the cooldown is completed you have a chance (Common, Rare, or Very rare) to receive that assignment again. (of course if you are in the same system-assignment-giver).
In other words, you won't receive every hour (or 2 for sector refresh) the same Common assignment.
