I got the "mission board"-mission. Unfortunately I have activated this mission in a abandoned system with only a abandoned space station.
There is no chance to visit a working mission board in this system. Every attempt to activate/deactive this mission in another system tells me something like "go to the other system". Even the Teleporter shows the symbol for this mission for the abandoned space station (without anything else then a Teleporter and a Galactic Trade Terminal inside).
There is no "Cancel" option for this mission and pressing the middle mouse button doesn't work either on the Log page.
Do you know any other method to cancel or reset or relocate such a mission?
I would even use a save game editor to get rid of this mission.

Since talking to a space station attendant is the only in-game option to abandon missions,
I think a Save Game Editor is indeed your best bet.
An editor which seems to be able to do what you want it to do, is NMSSaveEditor. *
There is a description of how to change mission statuses in the editor, here.**
Below you will find the outlines:
The ^WEAPGUYx identifiers are for armourer missions, so your identifier will be different. In your case, you might want to change the value to "-1", as this seemed to resolve an issue someone mentions in the same thread.
* This seems to be the GitHub version of the popular (NMSSE - No Man's Sky Save Editor), but, to download the latter, you will need an (unpaid) account.
** Before editing, make sure to make a backup of your save file!
