Today's puzzle felt surprisingly straightforward compared to yesterday. As soon as I saw Polar ice caps and Impact craters together, a lightbulb went on. The connection seemed almost too obvious to be true. I hesitated after the third clue, but seeing Olympus Mons (large volcano) next to A red sky locked it in. The final clue, The Curiosity rover, fits perfectly into the group, leaving no room for doubt. In the end, the answer Things seen on Mars is one of those 'slap your forehead' moments. It seems so simple once you see the full list.
