I enjoyed this story a lot. I disagreed with the host's interpretation that the MC was a symbol of man's hubris. Going back to a destroyed planet didn't seem to be the right play to me, and even though we know Mars doesn't have an atmosphere, they didn't--they were explorers. FWIW, my 9-year old daughter agreed with me. Although she prefers to believe the story was about griffins, arguing that it was never explicitly stated they were dinosaurs!
