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. 606 $aSpace flight to Mars$xPlanning 606 $aSpace microbiology 606 $aMars surface samples 606 $aMicrobial contamination$xPrevention 607 $aMars (Planet)$xExploration 615 0$aSpace flight to Mars$xPlanning. 615 0$aSpace microbiology. 615 0$aMars surface samples. 615 0$aMicrobial contamination$xPrevention. 676 $a629.45 712 02$aNational Research Council (U.S.).$bSpace Studies Board. 712 02$aNational Research Council (U.S.).$bDivision on Engineering and Physical Sciences. 712 02$aNational Academies Press (U.S.) 712 02$aNational Research Council (U.S.).$bCommittee on the Review of Planetary Protection Requirements for Mars Sample Return Missions. 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910964447503321 996 $aAssessment of planetary protection requirements for Mars sample return missions$94363400 997 $aUNINA
