Interesting premise so far. I like the space station, “making a new home” variation of sci-fi, so this seems to be hitting that beat well. I think you put in some good little details that feel believable and help ease me into the setting of what that life might be like. No terribly strong opinions on the characters or main plot yet, but I feel like the setup seems strong so far. 
miscellaneous suggestions
These are just a few things I thought as I was reading through. You’re totally welcome to take or leave any or all of these, but I figured I mention them in case they’re useful to you. I also didn’t pick up on any typos or formatting stuff, so not much to add on that.
I understand that the MC disobeyed orders by looking at something during a flight, but I don’t understand how that got his crewmates injured. It might be worth explaining that a little bit more, maybe flashing back to the scene or something?
The scene leading up to meeting Sterling jumps from the MC talking to their aunt, thinking to themselves, and then suddenly Sterling is speaking. I didn’t realize my character had gone anywhere or really what they were even doing (though I understand later that MC doesn’t actually know what errand they’re on, either). Anyway, it might be worth smoothing out that transition a little?
Besides that I was fairly happy with the story’s flow and mood and stuff. Looks like a good start, and I’m looking forward to what you have next!
