Getting Back to the Mad Moxxi Handsome Jack Jackpot Casino

I was progressing through the heist mission and then I decided to fast travel to Sanctuary to upgrade my inventory but when I tried to go back I did not see the casino as an option to fast travel back to. I could see the blue diamond highlighting the mission but I don’t see it as planet or other option to go back to. I tried to back to the ship capsule but there was no option for me to go back into it. Am I missing something or is there another way to get back to the casino to finish the quest? Has anyone else experience the same issue?

It should be visible on the map in galaxy view as a destination in the location list on the left side of the screen. Once selected you should then be able to get back to the zones you’ve unlocked so far.
