The UK Centre for Astrobiology was set up at the University of Edinburgh in 2011 [1] [2] by Charles Cockell. It was set up as a UK node, formally affiliated as an international partner with the NASA Astrobiology Institute (NAI) alongside other national nodes until the NAI's dissolution in 2019. It was established as a virtual centre to sit at the interdisciplinary boundary of planetary sciences/astronomy and biological/earth sciences investigating numerous aspects of life in the universe, specifically 'how habitable worlds form in the Universe and how life emerges, proliferates and leaves traces on these worlds' as well as engaging in work on the robotic and human exploration of space and in space ethics, philosophy and governance.
In the ten years from 2011 to 2021, the UKCA led or was affiliated with over 150 scientific papers in this period. Its published scientific work encompassed life in extremes, exoplanet biosignatures, biosignatures of life on Mars and early Earth, analogue research and other areas encompassing the habitability of planetary bodies. For example, the Centre oversaw the launch and implementation of the first biological mining experiment in space on the International Space Station in support of long-term human space settlement, demonstrating the use of microorganisms to mine economically important elements in space. [3] The centre's members were involved in Mars analog missions, expeditions to numerous extreme environments, as well as space missions such as NASA's Curiosity rover mission. The centre was microbiology lead on the NASA BASALT project (Biologic Analog Science Associated with Lava Terrains) to develop NASA plans for the human exploration of Mars. [4] It was scientific coordinator of the EU Framework 7 project MASE (Mars Analogues for Space Exploration) investigating microbial life in numerous Mars-like environments. [5] It organised a number of conferences in this ten-year period, hosting UK and European-level astrobiology conferences.
The UKCA launched a number of scientific and technical initiatives. It set up the world's first underground astrobiology laboratory in the Boulby Underground Science Laboratory, running a program MINAR (MIne Analog Research) from 2013 which brought in international teams from NASA, ESA, India, and universities across the UK and internationally to study life in the deep subsurface and test planetary exploration equipment. [6] [7] [8] In particular, MINAR focuses on the synergies between planetary exploration and mining, using the active mine environment to test technologies that create synergies between these two areas, such as rovers to carry out 3D mapping and gas detection for safety and structural assessments in mines and the exploration of other planets. [9] The initiative hosted the NASA Spaceward Bound project and ESA astronaut training.
The centre also launched numerous education initiatives. For example, the Centre set up and hosted the astrobiology academy, an initiative to bring teachers together to develop curriculum and lesson plans that used astrobiology to teach science in schools. The initiative produced lesson plans that were used to launch astrobiology in Scottish primary and secondary schools in association with the Scottish government's RAISE programme (Raising Aspiration in Science Education). The material became part of the National Resource Guide and the National Education Portal. It has been used to teach astrobiology across India in collaboration with the A.P.J. Abdul Kalam Centre, reaching tens of thousands of students.
In 2016, the centre, in collaboration with the Scottish Prison Service, launched Life Beyond, which involved prisoners in the design of settlements beyond Earth. Scottish prisoners published two books on settlement designs for the Moon and Mars. [10] [11] This led to the development of a distance learning Life Beyond course, which can be undertaken by any prisoner around the world, [12] distributed to English and Welsh prisons in collaboration with the Prisoners' Education Trust. Given the similarities between prisons and planetary stations (confinement, interdependence), the project tapped into prisoners' experience of confinement to imagine life beyond Earth, involving them in literacy, science, governance and civic responsibility. [13] Life Beyond was cited by EuroPris as an example of best education practice in European prisons. [14]
The centre led initiatives in considering space governance and space philosophy. For example, between 2013 and 2015 it led three international workshops to consider the future of forms of liberty beyond Earth, investigating the political philosophy of extraterrestrial settlement and in particular the effects of the extraterrestrial environment on forms of freedom. This led to three multi-author books published with Springer on the political philosophy of liberty beyond Earth. [15] [16] [17]
The centre launched and led undergraduate and postgraduate astrobiology courses at the University of Edinburgh leading to a textbook published with Wiley-Blackwell on Astrobiology, which is in its second edition. [18] It led and offered the world's first massive open on-line course (MOOC) in astrobiology in 2012 with Coursera, which attracted over 150,000 students.
Astrobiology, and the related field of exobiology, is an interdisciplinary scientific field that studies the origins, early evolution, distribution, and future of life in the universe. Astrobiology is the multidisciplinary field that investigates the deterministic conditions and contingent events with which life arises, distributes, and evolves in the universe.
Extraterrestrial life, colloquially referred to as alien life, is life that may occur outside Earth and which did not originate on Earth. No extraterrestrial life has yet been conclusively detected, although efforts are underway. Such life might range from simple forms like prokaryotes to intelligent beings, possibly bringing forth civilizations that might be far more advanced than humankind. The Drake equation speculates about the existence of sapient life elsewhere in the universe. The science of extraterrestrial life in all its forms is known as astrobiology.
Panspermia is the hypothesis, first proposed in the 5th century BCE by the Greek philosopher Anaxagoras, that life exists throughout the Universe, distributed by space dust, meteoroids, asteroids, comets, and planetoids, as well as by spacecraft carrying unintended contamination by microorganisms. Panspermia is a fringe theory with little support amongst mainstream scientists. Critics argue that it does not answer the question of the origin of life but merely places it on another celestial body. It is also criticized because it cannot be tested experimentally.
The NASA Astrobiology Institute (NAI) was established in 1998 by the National Aeronautics and Space Administration (NASA) "to develop the field of astrobiology and provide a scientific framework for flight missions." In December 2019 the Institute's activities were suspended.
The European Space Astronomy Centre (ESAC) near Madrid in Spain is the ESA's centre for space science. It hosts the science operation centres for all ESA astronomy and planetary missions together with their scientific archives. Past and present missions represented at ESAC include Akari, BepiColombo, Cassini–Huygens, Cluster, Exomars, Gaia, Herschel, Hubble, ISO, INTEGRAL, IUE, LISA Pathfinder, Mars Express, Planck, Rosetta, SOHO, Solar Orbiter, Venus Express, and XMM-Newton.
The Caves of Mars Project was an early 2000s program funded through Phase II by the NASA Institute for Advanced Concepts to assess the best place to situate the research and habitation modules that a human mission to Mars would require. The final report was published in mid 2004.
Planetary protection is a guiding principle in the design of an interplanetary mission, aiming to prevent biological contamination of both the target celestial body and the Earth in the case of sample-return missions. Planetary protection reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.
Boulby Mine is a 200-hectare (490-acre) site located just south-east of the village of Boulby, on the north-east coast of the North York Moors in Loftus, North Yorkshire England. It is run by Cleveland Potash Limited, which is now a subsidiary of Israel Chemicals Ltd. (ICL).
Extraterrestrial material refers to natural objects now on Earth that originated in outer space. Such materials include cosmic dust and meteorites, as well as samples brought to Earth by sample return missions from the Moon, asteroids and comets, as well as solar wind particles.
Charles Cockell is a British astrobiologist who is professor of astrobiology in the School of Physics and Astronomy at the University of Edinburgh and co-director of the UK Centre for Astrobiology.
The Mars Exploration Joint Initiative (MEJI) is an agreement signed between United States' space agency, NASA, and Europe's space agency, ESA to join resources and expertise in order to continue the exploration of the planet Mars. The agreement was signed in Washington D.C. in October 2009, between NASA administrator Charles Bolden and ESA director-general Jean-Jacques Dordain.
The Mars Astrobiology Explorer-Cacher (MAX-C), also known as Mars 2018 mission was a NASA concept for a Mars rover mission, proposed to be launched in 2018 together with the European ExoMars rover. The MAX-C rover concept was cancelled in April 2011 due to budget cuts.
Astrobiology Science and Technology for Exploring Planets (ASTEP) was a program established by NASA to sponsor research projects that advance the technology and techniques used in planetary exploration. The objective was to enable the study of astrobiology and to aid the planning of extraterrestrial exploration missions while prioritizing science, technology, and field campaigns.
Penelope J. Boston is a speleologist. She is associate director of the National Cave and Karst Research Institute in Carlsbad, New Mexico, and founder and director of the Cave and Karst Studies Program at New Mexico Institute of Mining and Technology in Socorro. Among her research interests are geomicrobiology of caves and mines, extraterrestrial speleogenesis, and space exploration and astrobiology generally.
Interplanetary contamination refers to biological contamination of a planetary body by a space probe or spacecraft, either deliberate or unintentional.
Terrestrial analogue sites are places on Earth with assumed past or present geological, environmental or biological conditions of a celestial body such as the Moon or Mars. Analogue sites are used in the frame of space exploration to either study geological or biological processes observed on other planets, or to prepare astronauts for surface extra-vehicular activity.
The Nexus for Exoplanet System Science (NExSS) initiative is a National Aeronautics and Space Administration (NASA) virtual institute designed to foster interdisciplinary collaboration in the search for life on exoplanets. Led by the Ames Research Center, the NASA Exoplanet Science Institute, and the Goddard Institute for Space Studies, NExSS will help organize the search for life on exoplanets from participating research teams and acquire new knowledge about exoplanets and extrasolar planetary systems.
The curation of extraterrestrial samples (astromaterials) obtained by sample-return missions take place at facilities specially designed to preserve both the sample integrity and protect the Earth. Astromaterials are classified as either non-restricted or restricted, depending on the nature of the Solar System body. Non-restricted samples include the Moon, asteroids, comets, solar particles and space dust. Restricted bodies include planets or moons suspected to have either past or present habitable environments to microscopic life, and therefore must be treated as extremely biohazardous.
Signs Of LIfe Detector (SOLID) is an analytical instrument under development to detect extraterrestrial life in the form of organic biosignatures obtained from a core drill during planetary exploration.
Kennda Lian Lynch is an American astrobiologist and geomicrobiologist who studies polyextremophiles. She has primarily been affiliated with NASA. She identifies environments on Earth with characteristics that may be similar to environments on other planets, and creates models that help identify characteristics that would indicate an environment might host life. Lynch also identifies what biosignatures might look like on other planets. Much of Lynch's research on analog environments has taken place in the Pilot Valley Basin in the Great Salt Desert of northwestern Utah, U.S. Her work in that paleolake basin informed the landing location of NASA's Perseverance Rover mission—at another paleolake basin called Jezero Crater. Jim Greene, Chief Scientist at NASA, called Lynch "a perfect expert to be involved in the Perseverance rover." Helping to select the proper landing site for NASA's first manned mission to Mars in 2035 is another of Lynch's projects. Lynch has appeared in multiple television series, as well as The New York Times, Nature, Scientific American, and Popular Science. Cell Press designated Lynch one of the most inspiring Black scientists in the United States.
