How does the mission distribution of some Crewskills work

I have Archeology. Sometimes I can select a mission to gain Artifact Fragments, sometimes not.

How does this exactly work? When is such a mission available and when not? Is it pure luck? Does it have a non visible cooldown?

The list is randomized every time you load a new area, or when a current mission completes, from a set list containing all types. There is no timer or cool down; if you stay in one area and do not run missions the list will not change. So if you want to get a particular mission, you'll have to log out and back in (or zone somewhere fast like your ship to Fleet) to attempt to get it into the random list. Or you can run quick lower-level missions of the same type to cause the list refresh.
