Book Description
The feasibility of extended flight in space has become more imminent in recent years and has increased interest in studies of the planets as possible environments for life. The existence of life on the planet Mars has been hypothesized by several authors. It is generally stated that the Martian planet would probably be the most likely planet in our solar system, other than Earth, capable of supporting life. The nature of such possible Martian life has been suggested to be similar to certain simple forms of terrestrial life. The first known attempt to test the validity of this assumption by means of laboratory experimentation was reported from our laboratory. These continuing studies on the survival and multiplication of certain terrestrial forms of life under a simulated Martian environment will be elaborated upon in this communication.

Book Description
This entirely updated second edition provides an overview on the biology, ecology and biodiversity of extremophiles. Unusual and less explored ecosystems inhabited by extremophiles such as marine hypersaline deeps, extreme cold, desert sands, and man-made clean rooms for spacecraft assembly are presented. An additional focus is put on the role of these highly specialized microorganism in applied research fields, ranging from biotechnology and nanotechnology to astrobiology. Examples such as novel psychrophilic enzymes, compounds from halophiles, and detection strategies for potential extraterrestrial life forms are discussed in detail. The book addresses researchers and advanced students in the fields of microbiology, microbial ecology and biotechnology.

Book Description
Significant Achievements in Space Bioscience 1958-1964 is a groundbreaking book that delves into the pioneering research conducted by the United States National Aeronautics and Space Administration during a crucial period in space exploration history. The book covers a wide range of topics related to space bioscience, including the effects of microgravity on living organisms, the development of life support systems for manned space missions, and the study of plant growth in space environments. Written in a clear and concise style, this book is a valuable resource for anyone interested in the intersection of biology and space exploration during the early years of NASA's involvement in manned spaceflight. The detailed descriptions of experiments and findings provide insight into the challenges and successes of conducting scientific research in the unique environment of space. The book also sheds light on the broader implications of these achievements for future space exploration missions and our understanding of the biological impact of long-term space travel. Overall, Significant Achievements in Space Bioscience 1958-1964 is a must-read for space enthusiasts, researchers, and students looking to deepen their knowledge of the history and advancements in space bioscience.

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
The Space Studies Board of the National Research Council (NRC) serves as the primary adviser to the National Aeronautics and Space Administration (NASA) on planetary protection policy, the purpose of which is to preserve conditions for future biological and organic exploration of planets and other solar system objects and to protect Earth and its biosphere from potential extraterrestrial sources of contamination. In October 1995 the NRC received a letter from NASA requesting that the Space Studies Board examine and provide advice on planetary protection issues related to possible sample-return missions to near-Earth solar system bodies.

Book Description
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 Sample Return: Issues and Recommendations. The specific issues addressed in this book include the following: The potential for living entities to be included in samples returned from Mars; Scientific investigations that should be conducted to reduce uncertainty in the above assessment; The potential for large-scale effects on Earth's environment by any returned entity released to the environment; Criteria for intentional sample release, taking note of current and anticipated regulatory frameworks; and The status of technological measures that could be taken on a mission to prevent the inadvertent release of a returned sample into Earth's biosphere.
