Open for debate....
I propose that both instances of Delta Vega, from "Where No Man Has Gone Before" and Star Trek: 2009, are one and the same.
Something that people complain about in the new films, and I understand the complaint, is the whole Delta Vega thing. Because they see on screen that Spock is looking up into the sky and seeing Vulcan collapse into a black hole, they are assuming that he's actually seeing it with his eyes. That would mean Delta Vega was a moon of Vulcan. Now, that can't be true because we know Vulcan has no moon. There is a dual planet, T'Ruhk, that shares a common center of gravity with Vulcan, according to what was seen in Star Trek: The Motion Picture. Delta Vega is not that place. It was volcanic world as seen from the surface of Vulcan.
Delta Vega could even be in a totally different system, and could be the same one in "Where No Man Has Gone Before" if you stretch your perceptions a little. Here's why....
In TOS "The Immunity Syndrome" it was established that Spock sensed the deaths of the crew of the USS Intrepid, all vulcans, from light years away.
What I surmise is that Spock was actually on the same world from WNMHGB, and he was seeing the death of Vulcan through his mind's eye, not his real eyes. He felt their deaths because he knew Nero was going to destroy Vulcan, and when it happened, he felt their deaths.
All it requires is this. Delta Vega is between Vulcan and Earth, and is still remote enough that at lightspeed, the Enterprise couldn't make the journey for years, but at warp speed, days. Kirk says in his log from the episode, "Star systems that are days away at warp, are now years in the distance."
Put Delta Vega right between Vulcan and Earth and when the Narada destroyed Vulcan and headed for Earth, it's on the way. Even if the Enterprise was headed for the Laurentian system, it can be on the way as well.
It's a slight stretch, but it can be rationalized to be the same place with a little creativity and not violate canon, either.
It seemed to me that the writers intended Delta Vega to be the same one as seen in the second pilot. So, if that's the case, we just have to see how it can be. And it can be, with a little work on our part to decipher it.
Memory Alpha is not always correct. The writers make assumptions too.
In my opinion, en.memory-alpha.org/wiki/Delta_Vega_Station
is the same place as en.memory-alpha.org/wiki/Delta_Vega_outpost
, and if you put it on a star map, it's between Earth and 40 Eridani A (the vulcan system) but a little closer to the edge of the galaxy. If it were so remote that Scotty was stationed there and no one ever came to relieve him, it almost fits the idea of a remote station that is fully automated. If it were in the Vulcan system, Scott wouldn't be that remote, would he? I mean, if it's the same place, all you have to do is put it halfway between and let Spock have a mind link to the destruction of vulcan and not take what was seen as literal. It was in a mind meld with Kirk, after all, not directly visible to Spock. He was using a mind meld to tell Kirk what happened, and he could even be seeing what Kirk saw, rather than what he saw with his eyes. No stretch here. Just have to interpret it correctly.
