Today, we have many tools to help us locate places precisely and navigate across the vast emptiness of oceans and space. However, in the past, navigation was a great challenge. In these series of nonfiction articles, readers will learn how early seafaring explorers used the stars, how later explorers developed new navigational tools to traverse the oceans, and how modern science has allowed us to explore space and the depths of the oceans. Voices offers readers a short traditional tale of how a Native American used the stars to find his way back to his village.
