Unfortunately we’ll never get to visit them in person if Prostetnic Vogon Jeltz has anything to say about it:
We are about to jump into hyperspace for the journey to Barnard’s Star. On arrival we will stay in dock for a seventy-two-hour refit, and no one’s to leave the ship during that time. I repeat, all planet leave is canceled. I’ve just had an unhappy love affair, so I don’t see why anybody else should have a good time.
