This reference is part of USA Today’s Debate: Voices and Perspectives series. Author Matt Doeden presents arguments both for and against advancing the space program, including facts and figures as well as experts’ opinions. The dangers inherent in space exploration are weighed against the possible payoff of more territory for human settlement. The book begins by asking the question should we stay or should we go and then provides a short history of space exploration. A discussion of the dangers of the space program contains a section on the Challenger, including primary source material such as USA Today news articles. A timeline, glossary and additional resources are at the end of the book.
