Siy (Spidermania: Friends on the Web) weaves a musical theme into the riveting story of NASA’s Voyager mission, which got underway in 1977 with the launch of two probes; originally designed to explore Jupiter and Saturn, they are now proceeding into interstellar space while transmitting data back to Earth. Throughout, Siy introduces scientists who contributed to the launch while bouncing between the probe’s paths (and attendant discoveries, such as volcanic activity on Io) and the pivotal work of Galileo and other early astronomers, highlighting the way science builds on past discoveries. In keeping with the musical theme, Siy concludes by discussing the Golden Record, a copper LP with copies riding aboard the Voyager probes, which contains photos, greetings, and music in wait of a potential extraterrestrial listener. It’s an engaging and readily accessible account of a remarkable—and ongoing—scientific success story. Ages 10–up.
Starred review from April 15, 2017
From the author of Cars on Mars: Roving the Red Plant (2011) comes this fascinating story of the twin Voyager probes, launched 40 years ago to travel to the outer planets of our solar system and now continuing into interstellar space.The story begins with two graduate students in the early 1960s. CalTech aeronautics student Gary Flandro, working part-time at NASA's Jet Propulsion Lab, is encouraged by his boss to investigate gravity-assist rocket trajectories to the outer planets. Flandro builds upon the idea of unlimited, gravity-propelled interplanetary space travel invented four years earlier by UCLA physics and mathematics student Michael Minovitch. It was Minovitch's idea of using a planet's gravitational field as a "slingshot" effect to enable a spacecraft to travel from one planet to another that made the Voyager mission feasible. In an accessible narrative written in an engaging conversational style, Siy explains how the probes work, what they carry onboard--including the remarkable Golden Record that readers will wish for more detail about--and what was discovered in their journeys to Jupiter, Saturn, Uranus, and Neptune, and their ventures beyond the solar system. Chapters are divided into subtopics, keeping the narrative manageable, and plentiful full-color photographs and schematics neatly complement the text. A lively, informative, and inspiring story of space exploration. (maps, photos, glossary, websites, further reading, source notes) (Nonfiction. 10-14)

Gr 4-8-Forty years after the launch of the twin space probes, Siy's well-researched and enthusiastic title depicts their conception, construction, major discoveries, and lasting legacy. After two introductory chapters, the narrative settles into a pattern: each chapter opens with a historical breakthrough, such as Galileo discovering four of Jupiter's moons, and then relates some pertinent information gained from the Voyagers' data as well as photos from specific encounters. The material is presented in a chronological order that roughly follows Voyager One's and Voyager Two's journeys, taking readers from launch on Earth through reaching interstellar space. The final chapter, on the Golden Records, the Voyagers' message in a bottle from Earth to aliens who may come across it, ends the book on a hopeful note. The back matter, especially the links found in "Keeping Up with the Voyagers," will be invaluable for those wanting more. Siy's conversational tone makes for quick reading, and she deftly injects humor into what could have been challenging passages about eight-tracks and other 1970s era technology. Beautiful full-page photographs, most of which are from the Voyager mission, enhance the text. VERDICT An engaging and captivating STEM title that deserves a place in most libraries.-Kacy Helwick, New Orleans Public Library

Grades 5-8 In 1965, a graduate student working part-time at the Jet Propulsion Laboratory envisioned the Grand Tour. Taking advantage of a rare planetary alignment during the 1980s, NASA could slingshot space probes from one planet to another, saving fuel while gathering data and beaming it back to Earth. With the space telescope and space shuttle projects already in progress, funding looked unlikely, but the Voyager mission got the go-ahead, and the rest is space exploration history. Forty years after the launch dates, Siy tells the story of the Voyager 1 and 2 space probes, from their brilliant conception and the idealistic Golden Record through the revolutionary series of planetary discoveries and Voyager 1's entry into interstellar space. Writing in a conversational style, Siy presents a good deal of information in an accessible way. She creates a sense of discovery as scientists interpret data, and images are sent back by the probes. Most double-page spreads include at least one illustration, usually a NASA image reproduced in color. A timely introduction to the Voyager mission.(Reprinted with permission of Booklist, copyright 2017, American Library Association.)

Siy's conversational narrative covers the major findings of the two Voyager spacecraft, still going since their launch in 1977. Each chapter features historical information about an outer planet's discovery, along with the data from Voyager 1 and 2 that has confirmed early hypotheses and added to our knowledge. The text includes excellent photos, with many taken from the Voyager missions. Reading list, websites. Glos., ind.
