Explore eight space-themed chapters with 40 pencil-and-paper activities for kids ages 8-12: eight word searches, eight mazes, eight secret messages, eight sudoku grids and eight matching-logic puzzles. Includes clear instructions, gradually increasing challenge, 4 by 4 and 6 by 6 sudoku, and complete solutions. One main activity per page, in a portable 64-page, 6 by 9-inch paperback. Bring a pencil and eraser for screen-free fun. The missions are imaginative; this is an activity book, not a science reference. Text and cover artwork were created with generative AI. Puzzles were generated with code and their solutions programmatically checked.
