Americans are divided over the future of the U.S. space program. Some say it's time to send astronauts back to the Moon, as well as to Mars for the first time. They believe that exploring these worlds will lead to all sorts of payoffs, including new scientific knowledge, new sources of energy, and perhaps even future homes for humans. Others strongly disagree. They argue that the dangers and costs of crewed space exploration are too great to be justified. They believe that robots can do a better job of exploring the Moon, Mars, and other parts of space—for much less money and with no risk to human life. Understanding this debate involves looking at the facts and figures and talking to experts on both sides. It also involves some probing questions: • In a time of economic crisis, should the United States be spending billions of dollars on crewed space exploration? • How would science, industry, and human society benefit from crewed missions to the Moon and Mars? • Who should foot the bill—the United States, a consortium of nations, or private business? To answer these questions, this book looks at the costs of crewed missions to Mars and the Moon, as well as the potential payoff; the dangers of space exploration, both physical and psychological; and the potential for human settlement on Mars. We'll hear a variety opinions—from astronauts, astronomers, U.S. presidents, and NASA officials. Supplemented with quotes, anecdotes, and discussions from the pages of USA TODAY, The Nation's No. 1 Newspaper, this book will broaden your understanding of the issue and help you form your own opinion, either for or against crewed missions to the Moon and Mars.

Forging the Future of Space Science available in PDF, EPUB and Kindle. From September 2007 to June 2008 the Space Studies Board conducted an international public seminar series, with each monthly talk highlighting a different topic in space and Earth science. The principal lectures from the series are compiled in Forging the Future of Space Science. The topics of these events covered the full spectrum of space and Earth science research, from global climate change, to the cosmic origins of life, to the exploration of the Moon and Mars, to the scientific research required to support human spaceflight. The prevailing messages throughout the seminar series as demonstrated by the lectures in this book are how much we have accomplished over the past 50 years, how profound are our discoveries, how much contributions from the space program affect our daily lives, and yet how much remains to be done. The age of discovery in space and Earth science is just beginning. Opportunities abound that will forever alter our destiny.

Download and read online ebook Dust in the Atmosphere of Mars and its Impact on Human Exploration write by Joel S. Levine. This book was released on 2018-10-12. Dust in the Atmosphere of Mars and its Impact on Human Exploration available in PDF, EPUB and Kindle. A major surprise of the Apollo Moon missions was the deleterious impact of lunar dust on the astronauts, their spacesuits and other equipment, and even inside the Command/Service Module during their return to Earth. Lunar dust permeated everything and impacted mechanical systems. The dust on the Moon’s surface was disturbed and became airborne by the routine actions of the astronauts as they walked and performed their exploration of the lunar surface. Over the last decade, as NASA’s plans for the human exploration of Mars have developed and matured, a major concern has been the possible negative impacts of Mars surface and atmospheric dust on human health and on the human surface systems and surface operations on the Red Planet. In this book, 41 Mars scientists, mission engineers and planners and medical researchers have reviewed our current understanding and identified the knowledge gaps in a wide range of areas, including the chemical, physical and electrical properties of Mars atmospheric dust; the evolution and occurrence of localized, regional and planetary-scale dust storms; the human health effects of Mars atmospheric dust, including inhalation of and potential toxicity of dust particles; and the impact of Mars atmospheric dust on surface systems and on surface operations, among others.
