Las Voyagers en el espacio

Two unmanned Voyager spacecraft were launched in 1977 with a mission of studying the large outer planets of our solar system. Voyagers in Space describes their journeys, the information the Voyagers learned about the giant planets, and their current task of exploring deep space. Photographs, diagrams, and time lines support the text. Build on students' intrinsic interest in space exploration to teach about distinguishing between fact and opinion and using past-tense verbs.
