The role of extremophile microbiomes in terraforming Mars - Nature nature.com Nov 17, 2025 8 facts
claimNASA’s Artemis program and ESA’s ExoMars mission are advancing the search for biosignatures and testing life-support biotechnologies under operational conditions, while SpaceX’s private initiatives are accelerating the pace of interplanetary transport.
measurementDuring the European Space Agency's EXPOSE-E and EXPOSE-R2 missions, Cryomyces antarcticus was exposed to simulated Martian conditions aboard the International Space Station for 1.5 years, resulting in over 60% of cells maintaining membrane integrity and metabolic activity, though colony-forming ability was reduced.
referenceThe European Space Agency's MELiSSA (Micro-Ecological Life Support System Alternative) project envisions a fully integrated microbial ecosystem capable of recycling water, carbon, and nutrients to support long-term human habitation in space.
perspectiveThe authors recommend establishing an International Microbial Testing Library (IMTL), hosted under international coordination (e.g., ESA, NASA, ISME), to curate candidate extremophiles and synthetic communities (SynComs) with standardized metadata.
referenceRabbow et al. (2012) documented the EXPOSE-E mission, an ESA astrobiology mission that spent 1.5 years in space.
claimGround-based Mars simulation chambers and orbital exposure experiments, including ESA’s EXPOSE-E, EXPOSE-R, EXPOSE-R2, BOSS, and BIOMEX missions on the International Space Station, serve as testbeds for investigating microbial resilience outside Earth's biosphere.
accountThe European Space Agency (ESA) BIOMEX mission exposed dried biofilms of Chroococcidiopsis species to Mars-analog conditions outside the International Space Station for 18 months.
referenceThe EXPOSE-R2 mission, conducted by the European Space Agency on the International Space Station, investigated astrobiological questions as detailed in a 2017 study by et al. in Frontiers in Microbiology.
Planetary protection: an international concern and responsibility frontiersin.org May 29, 2023 7 facts
claimNumerous national space agencies exist globally, including the European Space Agency (ESA), the United States National Aeronautics and Space Administration (NASA), the Japanese Aerospace Exploration Agency (JAXA), the Russian Roscosmos, the China National Space Administration (CNSA), the Indian Space Research Organisation (ISRO), the Canadian Space Agency (CSA), the United Arab Emirates Space Agency (UAESA), the UK Space Agency, the Centre National d’Etudes Spatiales (CNES) in France, the Italian Space Agency (ASI), and the Deutsches Zentrum für Luft-und Raumfahrt e.V. (DLR) in Germany.
claimThe COSPAR Planetary Protection Panel (PPP) plans to gather community input to reach a consensus on protocols for visiting icy moons in the Solar System, specifically in preparation for missions such as the ESA JUICE mission to Ganymede, the NASA Europa Clipper mission to Europa, and the NASA Dragonfly mission to Titan.
accountNASA provided expert advice and testing material for the ESA-JAXA study on Martian moon sample return, while JAXA conducted independent experimental and modeling activities to assist with the assessment.
claimThe ESA ECSS-Q-ST-70 standards define the objectives of planetary protection requirements rather than specifying the exact methods for implementation, allowing for organizational flexibility and evolution of methods.
accountESA and JAXA conducted a multi-year study on sample return mission concepts from the Martian moons Phobos and Deimos, which included the establishment of an ESA science group to evaluate the risk of unsterilized Martian material being present on the returned samples.
accountThe results of the ESA-JAXA-NASA study and the NAS-ESF review were presented to the ESA Planetary Working Group (PPWG) and COSPAR.
accountThe ESA-JAXA-NASA study on Martian moon sample return was reviewed by the US National Academy of Sciences (NAS) and the European Science Foundation (ESF), with involvement from COSPAR throughout the process.

claimThe Jupiter Icy Moon Explorer is an ESA orbital mission scheduled for launch in 2022 to explore Jupiter's icy moons, specifically Europa, Ganymede, and Callisto.
claimSpace agencies including NASA, ESA, and CNSA are expected to develop biosignature detection strategies for Mars, Europa, and Enceladus.
claimThe Rosalind Franklin rover, part of the ESA and ROSCOSMOS ExoMars mission, is designed to collect subsurface samples up to 2 meters deep, where radiation shielding may preserve evidence of active life on Mars.
