This chapter tells the story of a curious young girl named Rani who lives in a village and loves to ask questions about the world around her. After hearing her mother sing a traditional song about the Moon, Rani wonders how far away it is. The next morning, her brother Pratik excitedly shows her a TV broadcast announcing that India has landed on the Moon. Confused about how this was achieved, Rani and Pratik visit their neighbor, Aunt Nandini, who is a scientist.
