The Viking Lander Capsule 1 and 2 are subjected to terminal sterilization using Dry Heat Microbial Reduction. Extraterrestrial materials from planetary destinations with the possibility of supporting life are considered potentially harmful to humans and Earths biosphere until scientific study in a biologically secure laboratory can establish that there is no evidence of extraterrestrial life in the samples. As the search for life beyond Earth advances, Planetary Protection requirements are modified to reflect new scientific knowledge about the diversity of life on Earth and the detection capabilities of advanced instruments. Planetary Protection works in conjunction with solar system mission planners in order to ensure compliance with NASA policy and international agreements. Last month, the Office of Safety and Mission Assurance and NASA Safety Center released Planetary Protection Overview (SMA-STL-WBT-300) inSATERN. protection, which seek to prevent, mitigate and stop threats to individuals' human rights and fundamental freedoms, ensure that these rights are respected and protected by duty bearers and ensure access to basic services and humanitarian assistance. Overall, grants help us achieve our overall mission: protect human health and the environment. Jupiteris the fifth planet from the sun and the largest planet within the solar system. Titan and thought to be possible liquid hydrocarbon oceans, are seas of sand dunes similar to those found on Earth. Overall, there have been over 50 years of international collaboration in space exploration policy. 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. 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. Ganymede andCallistoare all covered with water ice. spacecraft have indicated that they may all have liquid water oceans beneath their icy crusts. Mars, which were defined as a region within which terrestrial organisms are likely to propagate, or It now has 110 states-parties. Laboratory examination of this returned hardware at NASAs Manned Spacecraft Center (now Johnson Space Center) included efforts to culture possible microbes on the hardware. corrugated terrain and other crustal deformations, indicating that the interior of the moon may be liquid today. bodies and mission types. to these levels, and a method of preventing recontamination of sterilized subsystems and contamination of material to In size, mass and composition,Venusis similar to Earth. sterilization. Accordingly, certain clarifications toNPR8020.12, Planetary Protection Provisions for Robotic Extraterrestrial Missionswill apply to M2020. The atmosphere of Venus is made up mainly of carbon dioxide and contains sulfuric acid. The there must meet a higher level of cleanliness and some operating restrictions will be imposed. and the nature of its destination (e.g., a planet, moon, comet or asteroid). has the potential to provide clues about life or prebiotic chemical evolution, a spacecraft going produce amino acids. The standard is a follow-on document complementingNPR 8715.24, Planetary Protection Provisions for Robotic Extraterrestrial Missions. Comets Encke, Schwassmann-Wachmann-3 and d'Arrest. and/or the origin of life. Visit the Explore page. The bioburden limit for a Mars rover is just 300 spores per square meter of the rovers surface. Lander systems not carrying instruments for the investigations of extant Mars life. If spacecraft parts or scientific instruments are susceptible to damage from heating, then there are other methods for microbial reduction, such as exposure to vapor hydrogen peroxide or ultraviolet light. contamination detection methods may also be employed to characterize biological loads. Hardware is wiped clean before final assembly and installation. . The first and most important step in complying withNASAPlanetary Protection policy He also taught Verification and Validation of Systems Engineering Projects and Reactor and Radiation Measurements Laboratory.. Backward contamination: The transfer of extraterrestrial organisms, if they exist, to Earths biosphere. The interaction of this atmosphere with solar ultraviolet UNOOSA serves as the secretariat for the U.N. General Assemblys only committee dealing exclusively with international cooperation in the peaceful uses of outer space: the U.N.Committee on the Peaceful Uses of Outer Space, known as COPUOS. Many peacekeeping missions have a mandate to protect civilians, in particular those under threat of physical harm. All missions leaving Earth are evaluated for impact from forward contamination. newer methods are attractive, however, because a biological load measurement that could take three days to complete using At laboratories located throughout the nation, we identify and try to solve environmental problems. For details on contacting a Planetary Protection Point of Contact (PoC), click below. Mars landers Lander systems designed to investigate extant Martian life. Agencys Mars Express orbiter have collected evidence of past liquid water on the planets surface. Accordingly, missions to Jupiter be assigned toCategory II. The United Nations (U.N.) Office of Outer Space Affairs (UNOOSA) is responsible for promoting international cooperation in the peaceful uses of outer space. Planetary Protection techniques that may be applied to spacecraft bound for Mars include clean manufacturing processes for is avoiding unintended encounters with solar system objects. contamination loads may be reduced by methods such as alcohol wiping, dry heat microbial reduction and hydrogen peroxide Since NASA is not a regulatory agency, the Federal Aviation Administration (FAA) is responsible for any U.S. payload launch made from a commercial requestor not directly sponsored by NASA. Through written materials and this website, EPA informs the public about our activities. Returned samples will have to be housed in a Bio-Safety Level 4 (BSL-4) biocontainment laboratory. In return, we share information and publicly recognize our partners. COSPAR accepts revised Planetary Protection policy that includes the mission categories (I-IV) that focus on target This is the foundation of the 2019 POC Policy which provides the conceptual framework, guiding principles and key considerations for the implementation of the POC policy. The dynamic nature of the places in which we operate means the security situation can change very quickly. Planetary Protection is an agreed international practice that is defined by the United Nations and its Committee on Space Research. A definition of done is a checklist of criteria that a product product increment or project must satisfy to be considered completed. not carrying instruments designed to search for evidence of extant Martian life are designated Category IVa and subject This same assessment also applies to comets and asteroids. Planetary Protection requirements are specific to the type of mission and explored planetary bodies. He presented issues and proposed solutions to NASA senior management. The Protection of Civilians (POC) is a responsibility which includes all parts of a peacekeeping mission, civilian, military and police functions. 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. 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. sensitivity of the particular life-detection experiments, whichever are more stringent or, alternatively, subsystems Planetary Protection controls on the forward contamination are intended to preserve the planetary record of natural processes on these bodies by preventing human-caused microbial introductions that could interfere with future astrobiological investigations. As such, Planetary Protection experts are crucial members of mission teams that search for life beyond Earth. 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. Handbook for the Microbial Examination of Space Hardware. This course covers what the requirements are for Planetary Protection for robotic missions, how to meet those requirements and lessons learned from past missions. Protecting civilians is the primary responsibility of governments; Peacekeepers with a mandate to protect civilians have the authority and responsibility to provide protection within their capabilities and areas of deployment where the government is unable or unwilling to protect; The protection of civilians mandate is a whole-of-mission activity, not only a military task, which embodies an active duty to protect; Protecting civilians is done in cooperation with humanitarian actors and with respect for humanitarian principles; The protection of civilians mandate is consonant with the principles of peacekeeping, including the consent of the host state, impartial mandate implementation, and the use of force only in self-defence or as authorized by the Security Council; The protection of civilians mandate is a priority mandate, pursuant to Security Council resolutions. European Space Agency, The first flight project using the new Planetary Protection recommendations was the Ranger project. These include head coverings, coveralls and shoe covers. Example acceptable contamination limits while conducting operations on Mars include: <1 viable Earth organism per cached sample. Others NASA's Planetary Protection policies and requirements ensure safe and verifiable scientific exploration for extraterrestrial life. Comets are known to contain stores of water ice, and scientists believe they may have delivered water (ice melted by impacts) to Earth billions of years ago, making life on this planet possible. TheCOSPAR Panel on Planetary Protectiondevelops and makes recommendations on Planetary Protection policy to COSPAR, which may adopt them as part of the officialCOSPAR Planetary Protection Policy. Visit NASA's websites forSaturns moonsandSolar System Explorationfor more information. Workers routinely wipe down flight hardware surfaces that remain accessible to maintain cleanliness. Compliance with Planetary Protection requirements is mandatory forNASAmissions, perNPD 8700.1, NASA Policy for Safety and Mission Success. About protected areas and land use. For most other destinations in the solar system, a returning mission is categorized as Unrestricted Earth Return. Asteroids, most of which are located in a region of space between Mars and Jupiter, are also believed to be remnants of the original material from which solar system bodies formed. are strict. Such transfers could have resulted from the high-velocity ejection of soil and rock caused by planetary impacts of comets It includes 17 Articles that provide the legal framework for space exploration. 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. there, along with ice pebbles and possible methane or ethane ground fog on surface. 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. in solar system history (though others speculate that Mars may have been cold and dry in this early period). do not inadvertently drop out of orbit and crash onto Mars after their missions are completed. Venus; A curiosity about the universe is of course a must. A mission to these worlds is either Category III (flyby/orbiter) or Category IV (lander). Everybody in a peacekeeping operation, including the civilian staff, military and the police, plays a role in protecting civilians. 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. Undifferentiated, metamorphosed asteroids; Io; others TBD, Venus, Earths moon, comets, non-Category I asteroids, Jupiter, Jovian satellites (except Io and Europa), Saturn, Saturnian satellites (except Titan and Enceladus), Uranus, Uranian satellites, Neptune, Neptunian satellites (except 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. 100 ppbTOCbaseline (Tier 1 & 2 compounds). Planetary Protection for Icy Moons: Updating the SSB Europa Report,May 2012. Thus, since Apollo 15, the Moon has been characterized as an Unrestricted Earth Return mission. In 1967, the United States, the Soviet Union and the United Kingdom were the first nations to sign the Outer Space Treaty, which is the legal framework for space exploration. The ESA Planetary Protection-related documents include. In 2008, COSPAR updated the Moon to a Category II body with significant interest relative to chemical and biological evolution of the solar system but with minimal risk of contamination during exploration. This policy sets forth NASA requirements applicable to robotic planetary flight programsand contains the processes needed to comply with Planetary Protection requirements. Prudence dictates taking precautions to avoid contamination of Europa, Ganymede and Callisto in order to ensure Although both Planetary Protection and Planetary Defense programs at NASA include the word planetary and aim to protect the planet, thats where similarities end. Therefore, Planetary Protection is not a major concern for missions to this planet. All commercial space companies that partner with NASA on missions must work in compliance with Planetary Protection requirements. To learn even more, we share information with other countries, private sector organizations, academic institutions, and other agencies. Lander post-sterilization biological burden levels or to levels of biological burden reduction driven by the nature and The most important type of microbe to consider is an endospore (or spore), which is a type of bacteria that can enter a dormant, protective state and survive even in the vacuum of space. New resources will continue to be added. The Department of Peace Operations (DPO) and the Department of Operational Support (DOS) in New York are also devoting significant attention to assisting all peacekeepers fulfil their role in protecting civilians effectively and efficientlyby: Tens of thousands of UN peacekeepers put themselves in harms way every day in order to protect civilians from the effects of physical violence. considerations for missions to Mars are thus substantial, and sterilization requirements for spacecraft landing on Mars 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. Mars; Planetary Protection is concerned with forward contamination of another world with life from Earth and backward contamination of Earth with a life-form from another world. Projects included Waste Treatment and Immobilization Plant at the Hanford Nuclear Reservation, Uranium Processing Facility at the Y-12 National Security Complex, Chemistry and Metallurgy Research Replacement Project for the Los Alamos National Laboratory, Salt Waste Processing Facility at the Savannah River Site, and the Permanent Ventilation System for the Waste Isolation Pilot Plant. scientists claim observations also reveal signs of possibly recent liquid water flows on the surface of Mars. NASA's Office of Planetary Protection promotes the responsible exploration of the solar system by implementing and developing efforts that . The most stringent requirements are those for Mars; Jupiters moons Europa, Ganymede, and Callisto; and Saturns moons of Titan and Enceladus due to the great potential for studying the origin, evolution and distribution of life on these bodies. 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. The surface is darker than originally Protect solar system bodies from biological contamination from Earth, Prevent harm to Earths environment from possible harmful extraterrestrial contamination, Support safe, sustainable exploration of chemical evolution and the origins of life, Construction of biologically managed (or low biological burden) spacecraft, Development of flight plans that protect planetary bodies of interest to the search for life, Development of plans to protect the Earth-Moon system from samples returned from extraterrestrial bodies, Formulation and application of space policy as it pertains to Planetary Protection, Description of the energetic potential of the primary launch vehicle, second stage, cruise stage and additional independent propulsion systems on primary and secondary payloads, Description of trajectory including flybys or gravity assists of celestial objects and orbital insertion or landing at the destination, Assessment of biological contamination risk and associated mitigation strategy for celestial objects, along the trajectory and at the orbiting or landed destination, For missions to the surface of the Moon, an inventory of propulsion products released into the lunar environment; additionally, for missions to Permanently Shadowed Regions or the lunar poles, an inventory of organics. The scientific consensus is that asteroids are not likely to support life as we know it. Agencys Huygens Probe during its descent through Titans atmosphere have shown gullies, streambeds and canyons On Venus, however, surface temperatures are over 450 degrees Celsius (842 degrees Fahrenheit), atmospheric pressure is 90 times that on Earth and there is no water. If a spacecraft has landed on or near Mars, Europa or Enceladus, then the returning leg of the mission is considered Restricted Earth Return. ocean. Any spacecraft going beyond Earth orbit and then returning to Earth is classified Category V (Earth Return). Space Studies Board publishes Recommendations on Quarantine Policy for Mars, Jupiter, Saturn, Uranus, Neptune and Titan. Planetary Protection is responsible for ensuring that all missions follow Planetary Protection requirements to protect solar system bodies from biological contamination from Earth and to prevent harm to Earths environment from possible extraterrestrial life forms. No Martian samples may be released from this facility until they pass an extensive battery of tests designed to detect any evidence of past or present biological activity. Share sensitive information only on official, secure websites. Some Forward Planetary Protection requirements protect the integrity of science exploration, including the search for and study of potential extraterrestrial life.
