for me the docking is a fickle beast at the best of time so i can understand the whole 'I get no Docking prompt'. To fix this i normally move away from the station (Not leave the system) maybe 3-4 hexes away (time compression is your friend here) then right click on the station icon on the system map.
As i haven't gotten far enough to have a clue about this mission (and i might miss it when i play through due to branching storylines in this game). I wish you luck and lots of credits
Thanks for taking the time to respond, I have been moving around this sector for about 7hs now. There is no Docking option. The station itself seems to be completely invulnerable for some reason. I destroyed all other stations in the sector without a problem.... (Hey I got bored flying around with nothing to do...) And I even rtied killing my own allies to escape from the sector I still get killed.
