The protagonist could use a foil soon. A sidekick, recurring dream character, or even the computer voice of his ship. Conversations with the foil is a quick way to let the reader get into the protagonist's head a little.
You've introduced him, now he needs a crisis/adventure to expose his want and maybe show us some more of his need for growth.
We also need to see him as a relative good guy in his situation. At this point we know little of his values other than, unlike some other characters, he doesn't kill or cause pain lightly.
