Book Description
The next frontier in space exploration is Mars, the red planet--and human habitation of Mars isn't much farther off. Now the National Geographic Channel goes years fast-forward with "Mars," a six-part series documenting and dramatizing the next 25 years as humans land on and learn to live on Mars. This companion book to the series explores the science behind the mission and the challenges awaiting those brave individuals. Filled with vivid photographs taken on Earth, in space, and on Mars; arresting maps; and commentary from the world's top planetary scientists, this fascinating book will take you millions of miles away--and decades into the future--to our next home in the solar system.

Book Description
Recent spacecraft and robotic probes to Mars have yielded data that are changing our understanding significantly about the possibility of existing or past life on that planet. Coupled with advances in biology and life-detection techniques, these developments place increasing importance on the need to protect Mars from contamination by Earth-borne organisms. To help with this effort, NASA requested that the NRC examine existing planetary protection measures for Mars and recommend changes and further research to improve such measures. This report discusses policies, requirements, and techniques to protect Mars from organisms originating on Earth that could interfere with scientific investigations. It provides recommendations on cleanliness and biological burden levels of Mars-bound spacecraft, methods to reach those levels, and research to reduce uncertainties in preventing forward contamination of Mars.

Book Description
Twenty years after the Viking missions of the ’70s, we are finally going back to Mars. No fewer than ten missions are planned for the period between 1996 and 2003, and it is likely that human explorers will follow soon after--perhaps by the middle of the twenty-first century. When they do, they will owe much to the Mars of romance, to the early pioneers whose discoveries and disappointments are brought to life in The Planet Mars: A History of Observation and Discovery. In this timely and vividly written account, William Sheehan traces human fascination with Mars back to the naked-eye observers of the planet. He recalls the early telescopic observers who first made out enigmatic markings and polar caps on its surface. Through lively historical anecdotes, he describes in detail the debate over the so-called canals of Mars, which encouraged speculation that the planet might be inhabited. Finally, Sheehan describes more recent theories about the planet, leading up to the present, when unmanned spacecraft have enabled us to make giant strides in exploration. Well documented and sparked with human interest, this book will be a useful companion and guide in interpreting the barrage of headlines about Mars that is sure to come over the next few years. Amateurs will appreciate the contributions that have been made to Martian studies by people like themselves, and professionals will find much original material that has never before been published. The American Mars Global Surveyor is scheduled for launch in November 1996, and soon after the American Mars Pathfinder will make its way toward the red planet. A Russian mission consisting of an orbiter and two landers will be launched in October 1997. These space travelers will write a whole new chapter in the dramatic story of Mars, a planet whose exploration has only just begun.
