Summary:
Dean is an astronaut, and he definitely chose the career so that he could help move humanity forward, not just because he didn't want to sit in an office, thank-you-very-much.
Becoming the first human to set foot on Mars was never part of his five-year plan, but he loved his job and couldn't say no when the opportunity arose.
He had spent plenty of time thinking about what he was risking never seeing again if something went wrong; his brother, brother-in-law, and the adorable kid they were adopting, not to mention his friends, his car, and pie.
What he hadn't considered was what, or who, he might find when he actually got there.
