Twenty-six essays written by workers in the space industry and interested lay people make a case for exploring Mars, arguing for the scientific objectives that could be achieved in the Martian "frontier" and even providing a cost and benefit analysis. The discussions suggest specific strategies in "getting there," flight profiles, and rocket designs utilizing nuclear electric propulsion. However, the questions remains--what happens when we arrive? In response, the authors speculate on life support, biomedical issues, transportation, and living spaces based on Biosphere 2 results. Lacks an index.

Three recent developments have greatly increased interest in the search for life on Mars. The first is new information about the Martian environment including evidence of a watery past and the possibility of atmospheric methane. The second is the possibility of microbial viability on Mars. Finally, the Vision for Space Exploration initiative included an explicit directive to search for the evidence of life on Mars. These scientific and political developments led NASA to request the NRC's assistance in formulating an up-to-date integrated astrobiology strategy for Mars exploration. Among other topics, this report presents a review of current knowledge about possible life on Mars; an astrobiological assessment of current Mars missions; a review of Mars-mission planetary protection; and findings and recommendations. The report notes that the greatest increase in understanding of Mars will come from the collection and return to Earth of a well-chosen suite of Martian surface materials.

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.

The idea of searching for evidence of life on Mars may strike some as far-fetched, even fanciful. But there is a compelling logic to such a quest, as well as an equally compelling excitement. Early environments were apparently sufficiently similar on Mars and Earth, and life arose so rapidly on Earth once conditions became clement, that emergence of life on both planets at that time is scarcely less plausible than emergence on only one. Furthermore, although a fossil on Mars might seem at first like a proverbial needle in a haystack, experience on Earth tell us that if we know where to look, finding evidence of ancient life is not particularly difficult, especially when one considers that such evidence can be relatively widely disseminated in the form of chemical or isotopic signatures. The key is to recognize that the search for ancient life on Mars will involve a logically designed sequence of missions, each of which will focus on defining ever more closely where and how biosignatures may be found. Although one can never rule out a chance discovery, this quest should not be approached as one that will yield to a single, expeditious mission. (In fact, the proposed strategy lends itself particularly well to the use of a series of relatively small, inexpensive spacecraft, rather than a single flagship-class mission). The search for life on Mars will take time and commitment, but the reward could be a discovery of inestimable importance, not just to science, but to humanity as a whole. Unspecified Center...

President Donald Trump signed the National Aeronautics and Space Administration (NASA) Transition Authorization Act of 2017, the first comprehensive NASA authorization act passed in seven years by Congress, authorizing $19.5 billion in funding for deep space exploration and human travel to Mars by 2030. NASA will lead our nation and our world on a journey to Mars. Like the Apollo Program, they will embark on this journey for all humanity. Mars is the horizon goal for pioneering space; it is the next tangible frontier for expanding human presence. Mars have found valuable resources for sustaining human pioneers, such as water ice just below the surface. Mars had conditions suitable for life, but will it our new home?"
