I'm sorry, but that's completely bogus as a reason,
"In my opinion".
Fixed that for you.
As for the rest of your post, I'm okay with those ideas, but I'm not talking about a possible version of the show, I'm talking about the actual show that was made in the 70's. And when I watch the show that was made, there are hints about a greater power behind everything. I don't need it explained any more than I need the backstory of C'thulu and the other Elder Gods explained. They exist, they're mysterious and that's part of the appeal. Season 1 of Space:1999 is full of eerie mystery and sometimes horror, that's part of the appeal and one of the reasons it's more popular than the action packed Star Trek wannabe of Season 2.
I remember a good comment by Michael Moorcock where he decried the increased need for fictional worlds to be "realistic" as stifling pure unbridled imagination. And I agree. Mainly because my introduction to fantasy was the late 60's / early 70's New Wave of Fantasy and they didn't give a shit about trying to explain things. Like both Moorcock and Zelazny each wrote a story set on an Earth that didn't rotate. I don't recall them going into details about how that would work, how life could still exist on the surface or at all, etc, etc, etc. They had a setting they wanted to use, so they used it. The Zelazny story was the awesome "Jack Of Shadows", the Moorcock one was the less awesome "Shores Of Death".
They told good stories with good characters, and you were either along for the ride or you weren't. They weren't trying to be Tolkien and be obsessive about the niggling details of the world around the characters. Ditto for Space:1999. I enjoy the strange, mysterious and eerie ride and yeah, I like that they're on the Moon and can't control anything.
As for the other concepts you've posted, if I were working on a Space:1999 reboot, I'd go one of two ways. The first being pretty much what you've described. The book cover you posted is not new, and I'd seen it on DA years ago, and thought it was a novel way to handle it. Although Stargate:Universe pretty much beat them to the punch when it comes to being on a ship they can't control. I've been meaning to watch that show, because I avoided it when it came out, and then someone said it was basically like an updated Space:1999 and I became intrigued.
The second way, which would be more controversial to old school fans, would be to not have the Moon blown out of orbit, and tell stories set on a much larger Moon city and / or additional Moon bases. These stories would not have aliens, and would not focus exclusively on the command staff or a military-esque group of people. I'm frankly tired of the idea that sci-fi movies or t.v. shows need to have that in order to be viable. I'd love it if JMS did stories set on B5 without the command crew or big events. I'd rather have Astro City style tales on B5 or Moonbase Alpha (or Beta or Delta). I guess we'd call that "Lower Decks" style stories in Trek Speak.
But your mileage may vary.
