I like all of the individual scenes you’ve got here, the premise is great, and (with some proofreading needed) the presentation is solid!
Regarding the general design, my biggest reservation is that as presented, it doesn’t seem like there’s much in the way of player choice involved in how anything goes down. I would be inclined to think about providing enough further detail that players can come up with alternate ways to solve things, decide where specifically to scavenge, figure out where best to do thruster testing, and so on (and anticipate some of the ways all of that can go wrong depending on those choices).
