Any “perceive yourself to X” phenomenon is something that happens within cognition of some abstract agent/person instance, whether they exist in some world or not. What kind of person instance is “perceiving themselves to black out” (that is, having blacked out)? Ghosts and afterlife seem more grounded than that. But for Earth/Mars question, both options are quite clear, and there is a you that perceives either of them in some of the possibilities, we can point to where those that perceive each of them are, and that is what would be correct for those instances to conclude about themselves, that they exist in the situations that contain them, known from the statement of the thought experiment.
What kind of person instance is “perceiving themselves to black out” (that is, having blacked out)?
It’s not a person instance, it’s an event that happens to the person’s stream of consciousness. Either the stream of consciousness truly, objectively ends, and a same-pattern copy will appear on Mars, mistakenly believing they’re the very same stream-of-consciousness as that of the original person.
Or the stream is truly, objectively preserved, and the person can calmly enter, knowing that their consciousness will continue on Mars.
I don’t think a 3rd-person analysis answers this question.
(With the correct answer being, of course, that the stream is truly, objectively preserved.)
Since I don’t think a 3rd person analysis answers the original problem, I also don’t think it answers it in case we massively complicate it like the OP has.
