Explanation:
- **Tragedy Degree**: The story does not contain profound tragic elements or strong emotional setbacks. While it acknowledges some ongoing issues on Earth like poverty, war, and natural disasters, these are not deeply explored or emotionally impacting within the narrative itself. Hence, it scores a 3.
- **Comedy Degree**: The story has some light-hearted moments and a relatively happy and hopeful ending, particularly when the crew finds a new habitable planet and rekindles hope for humanity. It is not highly comedic, but it leans towards a positive and uplifting tone. Thus, it scores a 5.
