very interesting concept. id certainly read it if it were a comic or book. though theres a few things you might want to look into.
im not critic, but i noticed you started the story with amnesia. now, i personally have no problem with this, but ive been around a few forums where people seem to LOATHE the idea of starting a series with amnesia. I'd look into why that is exactly, and see what you can do to pull it off in a way that doesnt immediately turn some people away. Im of the belief that any over-used trope or cliche can be pulled off if done tastefully.
Also, im just curious. Have you played the
Mass Effect series? (i highly recommend playing through it if you want to write a science fiction. plus its just great fun

) I was faintly reminded of some of the elements used in that series and the ones you presented. Now, im not saying that's a bad thing, but when things are very similar, you want to distinguish them from other already published ideas so they seem more fresh and original and not just copies.
I'll be more clear on that last point: You mentioned that there is a
Spoiler
child on board that ends up being the MC's imagination. In the last Mass effect. The main character sees a child all throughout the game, and is never quite explained till the end (and it's still pretty confusing). This lead to a theory among the fan base that the child you see never actually existed. That the main character was actually just "dreaming" it (it will make more sense if you play the game and watch the theory video).
There are a few reviewers out there who have argued (or tried to at least) that the Mass effect games also touched on humanities "insignificance" in the universe. Their reasoning as to why was full of holes and fallacies though, so it wouldn't worry too much about that. As i've said before on one thread here or another, try not to let the message cloud or anchor the story. You have to keep people who may disagree with your message interested.
Similarities aside, you have a really good spring board to start with. I'd say let the thoughts and ideas marinate for a bit, and maybe give a look see into the things i mentioned. Just a suggestion though.
hope this helps. Prost
