Summary
Summary
Scientists have identified at least 100 million pieces of space debris--from paint chips to nonoperational zombie satellites--floating in Earth's orbit. And over 100 tons of those pieces enter Earth's atmosphere each year!
Journey into outer space and learn about the dangers of space junk collisions, how scientists track them, and how space agencies are working to develop new technologies to clean up the space junk. Along the way, you'll hear from the scientists who are working to ensure that outer space remains a safe place to travel and explore. If we don't tackle the space junk problem, it might be impossible to travel into space; it could even trap us on Earth.

School Library Journal Review
Gr 5-8-A great cover beckons readers inside what should be a fascinating tour of the space around Earth-and it is, despite a somewhat dry and repetitious writing style. Each of the four chapters opens with a black spread that includes space photos and white type with red highlights; the following pages feature black print on white backgrounds. The book is filled with photos and sidebars that bring greater range to the text-and a few grammatical issues. There is little else available for students about this important topic for future space engineers. VERDICT General purchase.-Dorcas Hand, Annunciation Orthodox School, Houston, TX © Copyright 2015.

Kirkus Review
Humans have polluted the land, the seas, the top of Mount Everestnext stop: outer space. Well, surprise, writes science journalist Young in this limpid and engrossing (two words not normally associated with trash) overview: we've been leaving our junk in space for over 60 years now, even on the moon. Fortunately, we never got to the point of launching our nuclear waste into low orbit as once proposed, but we have sent over 6,600 satellites into spacesome as big as your head, some as big as a school busfor a number of scientific and military reasons. Their current status: 1,000 are still at work; 3,000 entered orbital decay and hurtled Earthward, mostly to burn up in the upper atmosphere due to friction, though some found terra firma. That leaves 2,600 "zombies." Young delivers a concise history of our flinging objects into outer spacealong with some excellent illustrations and photographsand explains the numerous terms such as zombies ("nonoperational satellites") and space junk ("any human-made debris in space," with about 20,000 pieces at the moment and an anticipated 60,000 in 15 years). Young also looks into work being done on NASA's Visual Inspection Poseable Invertebrate Robot to retrofit the zombies. In addition, wonder of wonders, countries are working on projects simply to go pick up the trash. Between her well-tempered writing style and her atypical subject, Young will have readers enthralled.

Booklist Review
You may not see a clear, blue sky in quite the same way again after reading this presentation on space junk, the rapidly accumulating conglomeration of human-made debris orbiting the earth at extremely high speeds. From old rocket sections and zombies (the 2,600 nonfunctioning satellites) to tiny fragments of metal and paint, well more than 100 million pieces race around the Earth, colliding and creating more debris. Since even small bits are destructive at high speeds, the danger of collision makes launching satellites or manned space vehicles increasingly risky. After explaining the facts and the issues, Young describes possible solutions, a surprisingly wide array of technologies proposed by scientists and engineers. Clearly written and concise, the book lays out the problem without sensationalizing it, while including human-interest details, such as your odds of being stuck by falling space junk (at one in several trillion, decidedly low). Small, well-captioned color photos, helpful diagrams, and interesting sidebars enhance the text. A natural for booktalking to STEM-minded kids, this slender volume belongs in many libraries.--Phelan, Carolyn Copyright 2015 Booklist
