Extraterrestrial nature reserves (ETNRs)
International Journal of Astrobiology, 2022 If human population growth is not controlled, natural areas must be sacrificed. An alternative is to create more habitat, terraforming Mars. However, this requires establishment of essential, ecosystem services on a planet currently unamenable to ...

Low Energy Subsurface Environments as Extraterrestrial Analogs [PDF]
Frontiers in Microbiology, 2018 Earth's subsurface is often isolated from phototrophic energy sources and characterized by chemotrophic modes of life. These environments are often oligotrophic and limited in electron donors or electron acceptors, and include continental crust, subseafloor oceanic crust, and marine sediment as well as subglacial lakes and the subsurface of polar ...

Photosynthesis and Photo-Stability of Nucleic Acids in Prebiotic Extraterrestrial Environments [PDF]
, 2014 Laboratory experiments have shown that the UV photo-irradiation of low-temperature ices of astrophysical interest leads to the formation of organic molecules, including molecules important for biology such as amino acids, quinones, and amphiphiles. When pyrimidine is introduced into these ices, the products of irradiation include the nucleobases uracil,
