I think you captured the theme sooo very nicely in this submission!
I also think you did good in matching the tone of your story with the music. Your first track does have this dream-like quality to it in the beginning that hints at the idea of space travel feel mysterious, and breaks into this really cool, almost a call-to-action vibe at the end, leading nicely into 'godspeed'. I think your third track is probably my favorite, just because it captures what my feelings would be if I were in space - 'dang it's huge, where should we go first?'. Very cool stuff.
My main piece of feedback would be that I personally would've liked to have heard you lean more into the dreamy, mysterious quality in your first track. Whenever I think of dream sequences in movies or video games there tend to be sections of the music that feature some weirder harmony that could've reinforced that idea in your track IMO.
Thanks for sharing what you got, and keep up the good work :)
