lifetime requirements to ensure against inadvertent contamination of the planet in the event of a crash. Titan and Enceladus two of Saturns 47 known moons are of biological interest to space scientists. Sample retrieval missions will be designed to contain the sample prior to its return to Earth, where they will be examined under quarantine and confirmed safe or sterilized prior to distribution to science laboratories. If they fail to meet the national standards, we can help them. Naval Academy and reactor operations supervisor for the Armed Forces Radiobiology Research Institute. And sample tubes shall be designed for opening after return to Earth in a manner that prevents additional contamination of samples during extraction. Planetary Protection considerations are thus a key component to no more than 110, Avoiding impact of Mars over a time period of 50 years with a probability of < 110, Avoiding impact of target bodies, including orbital lifetime constraints. an establishment that houses and feeds stray or unwanted animals. To accomplish these goals, the Office of Planetary Protection assists in the construction of sterile (or low biological burden) spacecraft, the development of flight plans that protect planetary bodies of interest, the development of plans to protect the Earth from returned extraterrestrial samples, and the formulation and application of space policy as it applies to Planetary Protection. Missions investigating Martian Special Regions, even if they do not include life detection experiments. such as cleanroom usage, aseptic assembly of spacecraft, partial sterilization of spacecraft He holds a Ph.D. in microbiology, molecular biology and biochemistry from the University of Idaho and a Bachelor of Science in microbiology from the University of Arizona. NASA's Office of Planetary Protection promotes the responsible exploration of the solar system by implementing and developing efforts that . Planetary Protection requirements for each mission and target body are determined based on the scientific advice of the Space Enceladusis the brightest body in the solar system because its surface reflects almost 100 percent of the sunlight A definition of done is a checklist of criteria that a product product increment or project must satisfy to be considered completed. contamination loads may be reduced by methods such as alcohol wiping, dry heat microbial reduction and hydrogen peroxide Forward contamination: The transfer of viable organisms, including microorganisms, from Earth to another celestial body. Planetary Protection also requires clean assembly practices, as well as preventing recontamination on flight hardware up to the last time of access prior to launch. Hardware is wiped clean before final assembly and installation. Restricted Earth Return requirements assure safety for Earths environment and responsible scientific study of returned hardware and samples. The Protection of Civilians (POC) is a responsibility which includes all parts of a peacekeeping mission, civilian, military and police functions. These include head coverings, coveralls and shoe covers. Observations of Titan have indicated that it may have lakes or oceans of liquid hydrocarbons on its surface in addition to As a senior Subject Matter Expert, he has been a lead author on over 24 peer review publications, two book chapters, 51 conference publications and presentations, and 24 engineering technical documents. The purpose of this handbook is to provide a compilation of procedures for the microbiological examination of space hardware and associated environments developed to meet the requirements of NASAs Planetary Protection and Space and Life Sciences programs. Planetary Protection techniques that may be applied to spacecraft bound for Mars include clean manufacturing processes for If any sign of the existence of a nonterrestrial replicating organism is found, the returned sample must remain contained unless treated by an effective sterilization procedure. methods and also because of additional personnel, training and requirements associated with molecular methods. thought, consisting of a mixture of water and hydrocarbon ice. In many cases, peacekeeping missions are authorized to use all necessary means, up to and including the use of deadly force, to prevent or respond to threats of physical violence against civilians, within capabilities and areas of operations, and without prejudice to the responsibility of the host government. cleaning and sterilization processes and greater operating restrictions. It is relevant starting in the Mission Concept Review and System Requirements Review phase by defining the Planetary Protection categorization to end-of-mission disposal reporting. Planetary Protection is the practice of protecting solar system bodies from contamination by Earth life and protecting Earth from possible life forms that may be returned from other solar system bodies. The initial assessment and detailed areas of interest are then directly used to evaluate the potential impacts for harmful contamination under the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies (U.N., 1967), Article IX. The following are a brief timeline of key events and selected references. there, along with ice pebbles and possible methane or ethane ground fog on surface. The Outer Space Treaty (OST) was signed on Jan. 27, 1967, in Washington D.C., London and Moscow. Overall, grants help us achieve our overall mission: protect human health and the environment. NASA has drafted a Mars sample return protocol specifying procedures for containment and handling. EPA works to ensure that: Americans have clean air, land and water; National efforts to reduce environmental risks are based on the best available scientific information; Federal laws protecting human health and the environment are administered and enforced fairly, effectively . Mars landers carrying instruments designed to search for evidence of extant Martian life are designated Category IVb and All mission components engage in dialogue and political advocacy, such as support for reconciliation, peace agreements or mediation, liaison with the government, or the resolution of local conflicts. Jupiter; The mission required additional cleaning measures, quarantine of the astronauts for 21 days and sample safety analysis to ensure that the samples would not pose adverse harm to the Earths biosphere. Restricted Earth Return requirements assure safety for Earths environment and responsible scientific study of returned hardware and samples. NASA carefully analyzes the potential for an as-yet-unknown extraterrestrial life-form to be released on Earth as a result of returning samples for scientific study. Backward contamination is assessed by looking at each step in the chain of contact from collecting samples on another planetary body through transporting and landing on Earth. Benardini has experience in leading and managing Planetary Protection missions as a cost account manager, overseeing and leading requirements definition and decomposition, developing implementation strategies, documenting project compliance, and conducting verification and validation activities/bioassays. The new course includes the definition of Planetary Protection, details of its implementation and practices, and information about its applicability to some of NASAs space flight missions. Finally, ground support equipment is subject to rigorous cleaning and testing for biological cleanliness throughout the assembly process. As described inNPR 8715.24, Planetary Protection Provisions for Robotic Extraterrestrial Missions, missions Transient Special Regions created by the presence of anRTGon the rover are included in these constraints: their absence shall be demonstrated by test and analysis. He presented issues and proposed solutions to NASA senior management. For more information, contact the PoC below. JavaScript appears to be disabled on this computer. It is two and a half times as massive as all of the other planets in the solar system combined. Titan and Enceladus (moons of Saturn); The atmosphere of Venus is made up mainly of carbon dioxide and contains sulfuric acid. He has conducted research as a Principal Investigator in the field of environmental microbiology, studying extreme environments for the past 13 years. Mars; More recently, because the existence of water at the lunar poles of the Moon provides a potential resource for future human exploration, COSPAR has called special attention to contamination concerns for PSRs, leading to sub-categorizations for missions that will explore those areas of the Moon. The technical assessment is then provided to the FAA for further consideration as part of the pre-application consultation and license application process. Additional information regarding Planetary Protection can be found on theCommittee on Space Research website. a microbial cultivation assay could be made in less than one hour using a molecular detection method. sensitivity of the particular life-detection experiments, whichever are more stringent or, alternatively, subsystems United Nations; promulgated by the The first restricted Earth return mission, requiring strict containment of extraterrestrial samples brought back to this planet, may be NASAs first Mars sample return mission, tentatively planned for the second decade of this century. This course covers what the requirements are for Planetary Protection for robotic missions, how to meet those requirements and lessons learned from past missions. Observations from the European Space A .gov website belongs to an official government organization in the United States. While Thetimeline of lunar explorationfrom 1959 to 2013 includes Luna 1, which performed a flyby in 1959, and LADEE and Change3, which orbited and landed on the moon, respectively. 100 ppbTOCbaseline (Tier 1 & 2 compounds). spacecraft have indicated that they may all have liquid water oceans beneath their icy crusts. A lock (LockA locked padlock) or https:// means youve safely connected to the .gov website. The mission of EPA is to protect human health and the environment. The purpose of this standard is to provide technical requirements to protect and enable current and future scientific investigations by limiting biological and relevant molecular contamination of solar system bodies through exploration activities and protecting the Earths biosphere by avoiding harmful biological contamination carried on returning spacecraft. Scientists have found no evidence of liquid water on themoonand none of the more than 2,000 samples of lunar material brought back to Earth by six Apollo missions yielded any evidence of past or present lunar biological activity. It also preserves the integrity of scientific research conducted in those environments. Jupiter is considered to be of significant interest relative to the process of chemical evolution and the origin of life, however, the chance that contamination carried by a spacecraft could compromise future investigations is considered to be remote. Missions to search for life beyond Earth include multidisciplinary teams of experts across scientific fields that include planetary science, geology and geoscience, astrobiology, astronomy, astrophysics, biology, microbiology, chemistry, and much more. The Aboriginal Protection Act 1869 was an Act of the colony of Victoria, Australia that established the Victorian Central Board for the Protection of Aborigines, to replace the Central Board Appointed to Watch Over the Interests of the Aborigines. Dr. J. Nick Benardini is the Planetary Protection Officer for NASA and the Office of Safety and Mission Assurance. There are five categories for target body/mission type combinations. Due to the presence of a radiothermal generator (RTG) used to power the M2020 rover, the M2020 project shall ensure that candidate landing sites exclude the following from the post-parachute-opening 3-sigma landing ellipse: Locations with ice or hydrated minerals at depths of <5 meters (based on MSL impact calculations), for which exposure to an RTG could cause liquid to be liberated sufficient to mobilize a particle of <50 nm in size. The basics include reducing how much energy and materials you use, reusing what you can and recycling the rest. Missions in this subcategory have requirements on the outbound (Earth to target body) phase only, corresponding to the category of that phase (typically Category I or II). Providing physical protection to hundreds of thousands of internally displaced people in POC sites, like in South Sudan; Deploying additional military and civilian mission personnel when a crisis erupts to provide protection, monitor human rights violations and create an environment conducive for humanitarian assistance, was carried out in the Democratic Republic of Congo; Developing mechanisms including early warning systems, community alert networks, community liaison arrangements, public information and reporting systems. Planetary Protection requirements and mission categories are based on the scientific advice of the Space Studies Board and on NASA or international policy guidelines. COSPAR re-establishes first set of quantitative Planetary Protection objectives. Accordingly, NASA assigns each mission aPlanetary Protection Category based on the type of planned encounter (e.g., flyby, orbiter or lander) and the type of planetary bodies that are encountered and explored during the mission (e.g., planet, moon, comet or asteroid). Although both Planetary Protection and Planetary Defense programs at NASA include the word planetary and aim to protect the planet, thats where similarities end. The three worlds that have the highest scientific interest in possible extraterrestrial life carry the strictest exploration requirements for Planetary Protection and are Mars, Europa and Enceladus. Accordingly, missions to Jupiter be assigned toCategory II. Caching hardware involved in acquisition, delivery, and storage of samples intended for Earth return shall be, Cleaned to a level of <300 heat resistant spores/m. Spacecraft carrying samples back to Earth pose a risk of unintended transfer of extraterrestrial life. there must meet a higher level of cleanliness and some operating restrictions will be imposed. Official websites use .gov Advising UN decision-making bodes such as the Security Council and General Assembly about threats to civilians in areas where peacekeepers are deployed; Developing policy and guidance to inform the implementation of POCmandates; Supporting missions to develop comprehensive POC strategies, based on the particular needs and situation of the mission which assists them in harnessing all available resources for the task; Developing POC training courses targeted at personnel prior to deployment, as well as those already working in peacekeeping operations. States bear the primary responsibility to protect civilians, and peacekeepers are not a substitute for political engagement to tackle root causes of conflict and violence. The first and most important step in complying withNASAPlanetary Protection policy Europa is an especially promising target for astrobiological Before joining the Defense Nuclear Facilities Safety Board, Forsbacka worked for the Department of Homeland Securitys Domestic Nuclear Detection branch. The five categories are. We work with businesses, non-profit organizations, and state and local governments through dozens of partnerships. The atmosphere of Titan, at a temperature of 94 Kelvin (290 degrees Mission personnel are also engaged in building the capacity of national authorities to promote and respect human rights, prevent and respond to violence against children and sexual and gender-based violence. To learn even more, we share information with other countries, private sector organizations, academic institutions, and other agencies. is not a product of biological activity. He was responsible for all aspects of NASA Headquarters mission oversight of this project. In return, we share information and publicly recognize our partners. He has been instrumental in planning and leading verification activities for the Mars 2020, InSight, Mars Science Laboratory, JUNO and Mars Exploration Rovers. preservation of the record of natural processes on these bodies. might have liquid water and making it a possible new candidate for astrobiological research. Visit the Explore page. (BSL-4 is the U.S. governments designation for the strictest level of biological containment.) National Aeronautics and Space Administration, Planetary Protection: Policies and Practices. Planetary Protection The history and development of Planetary Protection has been chronicled in many texts and articles. Jupiter along with Saturn, Uranus and Neptune is classified as a gas giant. All missions leaving Earth are evaluated for impact from forward contamination. Forsbacka also was the OSMA representative for the Nuclear Systems, Space Radiation and Space Protection Working Groups. Samples of extraterrestrial materials returned to Earth from bodies that are not considered suitable sites for life will not be required to meet containment requirements beyond those required to protect the scientific value of the samples. The air flow changes in NASAs cleanrooms for biologically sensitive hardware can be up to 350 per hour using an industrial Ultra-Low Particulate or High-Efficiency Particulate Air filtration system as per ISO 14644-1 Cleanroom Standards. Martian Special Regions from organic solids produced by photochemical reactions in Titans atmosphere. [1] [2] The Act made Victoria the first colony to enact comprehensive regulations on the lives of . Minimizing the probability of contamination using mission-dependent pre- and post-launch approaches, Limiting the probability that a planetary body will be contaminated during the period of exploration At school, a student should focus on biology, chemistry, physics and mathematics. the obligation of an alien to the government under which the alien resides. TheEuropean Space Agency(ESA) is committed to the responsible exploration of the solar system and works closely with NASA in the practice and development of Planetary Protection policy. In recent years, NASAs Mars Global Surveyor (MGS) and Mars Odyssey spacecraft have made observations that show evidence As the program executive for MMOD, Forsbacka was responsible for program execution of NASAs Procedural Requirements for limiting Orbital Debris. be analyzed must be in place. Accordingly, certain clarifications toNPR8020.12, Planetary Protection Provisions for Robotic Extraterrestrial Missionswill apply to M2020. This will give an estimate of the number of bacteria per square meter of surface. It may be most appropriate for you to contact your city, county, or state environmental or health agency, or another federal agency, rather than EPA. The effective implementation of the POC mandate requires a comprehensive, integrated and well-planned approach in order to address the various challenges missions with the mandate face. These courses are aimed at military, police and civilian personnel. spacecraft components and the use of cleanroom techniques during spacecraft assembly, test and launch operations. Specifically, the course typically covers, For information on offerings, contact Amy Baker, acourse instructor with SETI/Technical Administrative Services. Compliance with Planetary Protection requirements is mandatory forNASAmissions, perNPD 8700.1, NASA Policy for Safety and Mission Success. is now cold and dry, some scientists believe that conditions on the planet may have been much like those on Earth early As presented in the December 2015 Planetary Protection Subcommittee meeting, and pending final approval, the Mars 2020 (M2020) project will be designated a Category V Restricted Earth Return mission, while the outbound leg will be required to comply to Category IVb constraints at the subsystem level. However, reassessment of the Planetary Protection concerns for Mercury are underway due to the recent discovery of water ice and organics by the MESSENGER mission. Forsbacka resides in Silver Spring, Maryland with his wife and three daughters and is an avid bicycle commuter. The POC mandate in peacekeeping is guided by a set of principles: Depending on the nature of the threat to civilians, the mission will carry out a range of activities including engaging with parties to the conflict and affected communities, providing physical protection and the establishment of a protective environment. Workers wear these garments over their street clothes to prevent contaminants such as clothing fibers and hair and skin particles from entering the cleanroom and potentially transferring to sensitive spaceflight hardware. is avoiding unintended encounters with solar system objects. Examples clarifications include, (Note: The following language is comprised of direct quotes from the policy. Earths moon; They perform an advisory, coordination, monitoring and reporting role. The first mission to use Planetary Protection recommendations from the United Nations Committee on Space Research (COSPAR) was the Ranger project, a series of unmanned spacecraft in the 1960s whose objective was to take close-up images of the Moon. Visit theSolar System Explorationfor more information. are strict. Exposed hardware surfaces are cleaned during the assemble process by alcohol wiping. As NASAs Planetary Protection Officer, James Nick Benardini knows his role is all about the community: his NASA discipline colleagues, agency programs and projects, the international community, and academia. Visit NASA's websites forMarsandSolar System Explorationfor more information. Given the multidisciplinary nature of topics covered by Planetary Protection, there is not a one-size-fits-all approach. All spacecraft such as orbiters, landers and rovers must be built in cleanrooms that meet International Organization for Standardization specifications for particulate control and air flow as well as gowning protocols for protective clothing. COSPAR accepts revised Planetary Protection policy that includes the mission categories (I-IV) that focus on target Visit theNASAwebsite for Jupiters moonsandSolar System Explorationfor more information. Clarifications to the Special Regions include a lower temperature limit of -28C, reevaluation of the 500 year timescale for limits, and a focus on regions including dark streaks. It addresses and is relevant to both crewed and robotic missions and covers the technical details a mission should consider for the design and execution of the Planetary Protection mission throughout the project life cycle. The concern for these missions is the protection of the Earth from back contamination resulting from the return of extraterrestrial samples (usually soil and rocks). frozen deposits of these compounds. Cassini observations have revealed a water vapor plume in the southern polar region of Enceladus, hinting that this moon Apollo 12 astronauts retrieved the Surveyor 3 camera from the surface of the moon and brought it back to Earth for analysis. Planetary Protection is an agreed international practice that is defined by the Last month, the Office of Safety and Mission Assurance and NASA Safety Center released Planetary Protection Overview (SMA-STL-WBT-300) inSATERN. Thus, since Apollo 15, the Moon has been characterized as an Unrestricted Earth Return mission. Some problems that seem like something we would handle are actually the responsibility of other federal, tribal, state or local agencies. Once the room has been cleaned, the team goes back to begin cleaning again. This policy directive covers the ways in which NASA assures acceptable levels of flight crew safety and mission success risk.
