Write a science fiction story about a group of five astronauts who journey to a distant galaxy, and subsequently crash land on a barren, seemingly uninhabitable planet. The story should explore the themes of survival, isolation, and the unknown, and should feature a mix of scientific detail and narrative tension. Consider incorporating elements of post-apocalyptic fiction, as well as subtle nods to classic sci-fi tropes. The story should focus on the emotional and psychological journey of the characters as they navigate this unfamiliar world and grapple with their own mortality.
