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. The assignment of categories for specific missions is made by the NASA Planetary Protection Officer based on multidisciplinary scientific advice. Dr. Matthew Matt Forsbacka is the Mission Assurance Standards and Capabilities Division director, responsible for the development and maintenance of NASA directives and standards pertaining to SMA, as well as related methods, tools and guidance. About protected areas and land use. Another important category of definitions is the class of ostensive definitions, which convey . All policies, guidelines and mission requirements are publicly available to commercial space companies. Careful mission design and planning are essential elements when considering Planetary Protection
Planetary Protection requirements to control forward contamination begin on Earth and are accomplished by understanding mission science, operational requirements and goals based upon the environmental characteristics of each planetary destination. spacecraft components and the use of cleanroom techniques during spacecraft assembly, test and launch operations. This policy sets forth NASA requirements applicable to robotic planetary flight programs and contains the steps needed to comply with Planetary Protection requirements. The National Research Councils Space Studies Board has thus concluded that no special containment is needed for returned samples of interplanetary dust, comets and some asteroids (depending on their compositional type). When exploring a target body that potentially supports Earth life, spacecraft will undergo stringent cleaning and sterilization processes and may be subject to certain operating restrictions. It now has 110 states-parties.

an establishment providing food and shelter (as to the homeless). Lander systems designed to investigate extant Martian life. Forward Planetary Protection requirements protect the integrity of science exploration, including the search for and study of potential extraterrestrial life. radiation could generate saturated and unsaturated hydrocarbons as well as nitriles, through methane photolysis. Jupiteris the fifth planet from the sun and the largest planet within the solar system. to biological contamination limits: their biological burden is restricted to a level no greater than the Viking-lander 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. Hardware is wiped clean before final assembly and installation. Earth return samples from the Moon were originally treated as a Planetary Protection Restricted Earth Return up until Apollo 11. As the largest moon of Saturn, We work with businesses, non-profit organizations, and state and local governments through dozens of partnerships. Safety is the condition of a steady state of an . Callisto differs from Europa and Ganymede in some important respects, it also appears to have a subsurface liquid water A subcategory called "Unrestricted Earth Return" is defined for solar system bodies deemed by scientific opinion to have no indigenous life forms. Finally, peacekeeping missions also conduct activities which support the establishment of a protective environment that increases security and protects civilians from violence. Planetary Protection is an agreed international practice that is defined by the United Nations and its Committee on Space Research. Visit theSolar System Explorationfor more information. The five categories are. Some scientists have speculated that, over billions of years, impacts on the surface Secure .gov websites use HTTPS Water does not exist in liquid form on comets, however, and the scientific consensus is that comets cannot support life as we know it. 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. spacecraft have indicated that they may all have liquid water oceans beneath their icy crusts. Planetary Protection requirements for MGS and Mars Odyssey are intended to ensure that the orbiting spacecraft Some researchers involved in the laboratory examinations claimed they found a viable terrestrial microbe specifically,Streptococcus mitisbacteria embedded in this hardware, but others have argued that the microbial life they found was a result of contamination introduced during the laboratory examination. A report issued by a subcommittee of the International Council of Scientific Unionsdescribes the first code-of-conduct for Planetary Protection and recommended that the newly formed. COSPAR accepts revised Planetary Protection policy that includes the mission categories (I-IV) that focus on target
might have liquid water and making it a possible new candidate for astrobiological research. The planet Jupiter is primarily composed of hydrogen with a small proportion of helium; it may also have a rocky core of heavier elements under high pressure. Ganymede andCallistoare all covered with water ice. This planet appears Agencys Mars Express orbiter have collected evidence of past liquid water on the planets surface. corrugated terrain and other crustal deformations, indicating that the interior of the moon may be liquid today. Space-faring agencies that implement Planetary Protection policies include the European Space Agency, the Japanese Aerospace Exploration Agency and others. The surface is darker than originally Most recently, observations of these three planetary satellites by the Galileo products could condense as aerosols and reach the surface, where some could liquefy while others take solid form. NASA's Planetary Protection policies and requirements ensure safe and verifiable scientific exploration for extraterrestrial life. For the Hayabusa I and II missions, JAXA worked with NASA to ensure compliance to Committee on Space Research Planetary Protection policy. He was responsible for reviewing the Nuclear Launch Safety Approval Requests submitted by programs and projects that plan to launch radioactive material in space. Titan and Enceladus (moons of Saturn);
Thus, our aim, as an Area of Responsibility within the Global Protection Cluster, is to lead the coordination of child protection efforts in humanitarian settings in order to . Planetary Protection requirements provides a significant chance that contamination could compromise future investigations., Earth-return missions from bodies deemed by scientific opinion to have no indigenous life forms.. 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. 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. If a spacecraft has landed on or near Mars, Europa or Enceladus, then the returning leg of the mission is considered Restricted Earth Return. 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 Endangered Species Act is primarily managed by the. Earth;
While some of the moons of Jupiter and Saturn are considered good sites for astrobiological investigation, the consensus is that the environments of Jupiter and Saturn themselves are not suited to supporting life as we know it, and Planetary Protection is currently not a major concern for these gas giants. Planetary Protection for Icy Moons: Updating the SSB Europa Report,May 2012. The ESA Planetary Protection-related documents include. Scientists 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. There are five categories for target body/mission type combinations. The technical assessment is then provided to the FAA for further consideration as part of the pre-application consultation and license application process. Special Regions as formally defined inNPR8020.12D Section 5.3.2.5 or as modified by mutual agreement prior to launch, pending evaluation of the definition rendered by the 2014-15MEPAG/SSB/ESF evaluations, and subject to review by theNASAPlanetary Protection Subcommittee. Concerns regarding lunar and planetary contamination are raised at the International Astronautical Federation 7th
Forward contamination is assessed by looking for evidence of Earth-like environments on other planetary bodies and considering the potential for a terrestrial microbe, transported on a spacecraft, to find a refuge and remain viable in an extraterrestrial setting. The policy promotes consistency in approach while recognising the varied operational contexts faced by UN Peacekeeping operations and the requirement for flexibility to respond to changing environments and the different resources available across the lifecycle of a mission. Even if these efforts are not always very visible, the importance of this work, aiming to support the host government in its responsibilities to protect civilians should not be underestimated. Any spacecraft going beyond Earth orbit and then returning to Earth is classified Category V (Earth Return). Our Protective Mission. European Space Agency,
are still the standard forward contamination control method, in part because of the lack of comparability with molecular Prior to that role, he was the acting director for the Prometheus nuclear systems technology, responsible for all cross-discipline efforts in nuclear power and propulsion technologies for NASA.
