Preventing the Forward Contamination of Mars
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.
When Biospheres Collide
NOTE: NO FURTHER DISCOUNT FOR THIS PRINT PRODUCT- OVERSTOCK SALE-- Significantly reduced list price This new book from the NASA History Series tackles an interesting duo of biological problems that will be familiar to anybody who has seen photos of Apollo astronauts quarantined after their return to Earth.Namely, how do we avoid contaminating celestial bodies with Earthly germs when we send spacecraft to study these bodies, and how do we avoid spreading foreign biological matter from space when our robotic and human spacefarers return to Earth?Biological matter from an external system could potentially cause an unchecked epidemic either on Earth or in space so strict precautions are necessar...
Review of the MEPAG Report on Mars Special Regions
Planetary protection is a guiding principle in the design of an interplanetary mission, aiming to prevent biological contamination of both the target celestial body and the Earth. The protection of high-priority science goals, the search for life and the understanding of the Martian organic environment may be compromised if Earth microbes carried by spacecraft are grown and spread on Mars. This has led to the definition of Special Regions on Mars where strict planetary protection measures have to be applied before a spacecraft can enter these areas. At NASA's request, the community-based Mars Exploration Program Analysis Group (MEPAG) established the Special Regions Science Analysis Group (S...

Review and Assessment of Planetary Protection Policy Development Processes
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.
Topics in Ecological and Environmental Microbiology
This book provides an overview of ecological aspects of the metabolism and behavior of microbes, microbial habitats, biogeochemical cycles, and biotechnology. It was designed by selecting relevant chapters from the comprehensive Encyclopedia of Microbiology, 3rd edn., and inviting the original authors to update their material to include key developments and advances in the field.
Space Studies Board Annual Report 2010
The Space Studies Board (SSB) was established in 1958 to serve as the focus of the interests and responsibilities in space research for the National Academies. The SSB provides an independent, authoritative forum for information and advice on all aspects of space science and applications, and it serves as the focal point within the National Academies for activities on space research. It oversees advisory studies and program assessments, facilitates international research coordination, and promotes communications on space science and science policy between the research community, the federal government, and the interested public. The SSB also serves as the U.S. National Committee for the International Council for Science Committee on Space Research (COSPAR). This volume reviews the organization, activities, and reports of the SSB for the year 2010.
Assessment of Planetary Protection Requirements for Mars Sample Return Missions
NASA maintains a planetary protection policy to avoid the forward biological contamination of other worlds by terrestrial organisms, and back biological contamination of Earth from the return of extraterrestrial materials by spaceflight missions. Forward-contamination issues related to Mars missions were addressed in a 2006 National Research Council (NRC) book, Preventing the Forward Contamination of Mars. However, it has been more than 10 years since back-contamination issues were last examined. Driven by a renewed interest in Mars sample return missions, this book reviews, updates, and replaces the planetary protection conclusions and recommendations contained in the NRC's 1997 report Mars...
Inner Solar System
This book investigates Venus and Mercury prospective energy and material resources. It is a collection of topics related to exploration and utilization of these bodies. It presents past and future technologies and solutions to old problems that could become reality in our life time. The book therefore is a great source of condensed information for specialists interested in current and impending Venus and Mercury related activities and a good starting point for space researchers, inventors, technologists and potential investors. Written for researchers, engineers, and businessmen interested in Venus and Mercury exploration and exploitation.
The Goals, Rationales, and Definition of Planetary Protection
Solar system exploration is in an extraordinary state of expansion. Scientific capabilities to search for evidence of extant or relic life outside Earthâ€"among the principal goals of solar system explorationâ€"are advancing rapidly. In this time of rapid transition in exploring solar system bodies, the importance of reexamining planetary protection policies, including the need for clarity in how NASA establishes such policies, has become more urgent. Overall, this study seeks to review the current state of planetary protection policy development, assess the responsiveness of the policy development process to contemporary and anticipated needs, and recommend actions that might assure the effectiveness of NASA's future coordination and execution of planetary protection. This interim report focuses on the goals of and rationales for planetary protection policies and suggests a working definition of planetary protection consistent with those goals. It does not address future commercial planetary missions, human missions to planetary bodies, or roles and responsibilities for implementing policies, but these issues will be addressed in the final report.
