I found out where from Valve pulled out the name “Black Mesa” and probably “Half Life”.
I was watching the sky through my…eyes…, drawing down stars and looking them up in Stellarium. Now, in the Orion constellation, on the Hunter’s “neck”(a bit higher from Betelgeuse and Bellatrix) there’s this small star bears the name “Lambda Orionis”.
Here’s a quote from Wikipedia:
Does “λ” sounds/looks familiar to you? Does Meissa(pronounced “Mesa”) ring a bell?
I bet that’s another source from which Valve got those names from.
And there’s also this…irony? “Black Mesa” which would kind of mean “Black Shining”.
This goes to Gabe so I can get a confirmation.
