Found LEGO City space set near Discovery Green

I found a LEGO City space set this afternoon around 2:30pm near Discovery Green downtown Houston, by the main fountain off McKinney Street. The box is blue and yellow, a bit creased on the top edge, and inside there's a spaceman minifigure in a red suit with a shiny visor, plus a small red space rover. There’s a rocket sticker on the front and a tiny star sticker on the back—these small details helped me spot it again. The contents look complete and the whole thing seems in good condition, just a little dusty from being outdoors. If this belongs to someone, I’d be glad to return it—tell me the color of the helmet and the sticker on the box to verify ownership.
