Travel to deep space and back again with The Mars Challenge, a nonfiction graphic novel for teens about the science and logistics of a manned mission to Mars. Nadia is a teen with a dream: to be the first woman on Mars. But to get there, she's got to learn all she can about the science of spaceflight. It's a good thing her friend Eleanor is an Attitude Determination and Control Officer—basically, she pilots the International Space Station! Eleanor takes Nadia on a conceptual journey through an entire crewed mission to Mars, and explains every challenge that must be overcome along the way; from escaping Earth's gravity well, to keeping the crew healthy as they travel through deep space, to setting up a Mars base, to having enough fuel for the trip home! In The Mars Challenge, writer Benjamin A. Wilgus and artist Wyeth Yates bring the reader on a thrilling interplanetary voyage and clearly illustrate the scientific concepts and complex machinery involved. Humans can reach Mars in our lifetime—this book explains how it can be done.

Protecting Earth's environment and other solar system bodies from harmful contamination has been an important principle throughout the history of space exploration. For decades, the scientific, political, and economic conditions of space exploration converged in ways that contributed to effective development and implementation of planetary protection policies at national and international levels. However, the future of space exploration faces serious challenges to the development and implementation of planetary protection policy. The most disruptive changes are associated with (1) sample return from, and human missions to, Mars; and (2) missions to those bodies in the outer solar system possessing water oceans beneath their icy surfaces. Review and Assessment of Planetary Protection Policy Development Processes addresses the implications of changes in the complexion of solar system exploration as they apply to the process of developing planetary protection policy. Specifically, this report examines the history of planetary protection policy, assesses the current policy development process, and recommends actions to improve the policy development process in the future.

Get ready for lift-off on a Martian adventure! Have you ever imagined living on another planet? What about Mars? With not enough air to breathe, sunlight to keep us warm, or any available food and water, life on Mars is going to be a challenge... but it just might be possible! Take a journey to the Red Planet in How to Survive on Mars. Discover natural wonders like ancient polar ice caps, the highest volcano in the solar system and a 45-kilometre-wide impact crater that was once a Martian lake. Packed with stunning photographs, fun activities and quizzes, this book will show you what you need to do to survive on Mars! Join scientists, engineers, archaeologists, ethicists and science-fiction writers for a space exploration adventure. Reading level varies from child to child, but we recommend this book for ages 8 to 12.

From Hugo and Nebula Award-winning author, Geoffrey A. Landis, comes an epic of near-future exploration of Mars in his debut Nebula Award nominated novel, Mars Crossing. By the middle of the 21st century, humanity has finally landed men on Mars–only to watch helplessly as the first two missions end in catastrophe and death. With resources running out, a third–and perhaps final–mission to Mars is hastily mounted, with a crew of four men and two women. But from the moment of their arrival on Mars, everything begins to go wrong. The fuel tanks that were to have supplied their return trip are found corroded and empty. Their supplies are running out and their life support systems are beginning to fail. And any rescue mission won't reach them for months, or even years–if at all. The crew's only hope for survival lies in a desperate plan: an agonizing trek halfway across the surface of Mars to a ship designed to carry only half their number. Torn by conflict and dissent, and troubled by secrets that endanger them all, they must embark on an ordeal that will test them to the limits of endurance.

With current technology, a voyage to Mars and back will take three years. That’s a lot of time for things to go wrong. But sooner or later a commercial enterprise will commit itself to sending humans to Mars. How will the astronauts survive? Some things to consider are: ith current technology, a voyage to Mars and back will take three years. That’s a lot of time for things to go wrong. But sooner or later a commercial enterprise will commit itself to sending humans to Mars. How will the astronauts survive? Some things to consider are: • Who decides what medical resources are used for whom? Who decides what medical resources are used for whom? • What is the relative weight of mission success and the health of the crew? What is the relative weight of mission success and the health of the crew? • Do we allow crewmembers to sacrifi ce their lives for the good of the mission? Do we allow crewmembers to sacrifi ce their lives for the good of the mission? • And what if a crewmember does perish? Do we store the body for return to Earth or give the member a burial in space? Questions like these, and hundreds of others, have been explored by science fi ction, but scant attention has been paid by those designing missions. Fortunately, the experience gained in polar exploration more than 100 years ago provides crews and mission planners with a framework to deal with contingencies and it is this that forms the core of this book. Why the parallels between polar and space exploration? Because polar exploration offers a better analogy for a Mars mission today than those invoked by the space community. Although astronauts are routinely compared to Lewis and Clark, Mars-bound astronauts will be closer in their roles to polar explorers. And, as much as space has been described as a New Frontier, Mars bears greater similarity to the polar regions, which is why so much can be learned from those who ventured there.
