Viruses in Extreme Marine Environments and Their Potential Existence in Extraterrestrial Environments. [PDF]
Viruses are abundant and widespread in extreme marine environments, such as sea ice, hydrothermal vents, and ocean trenches. They occur at temperatures up to 122 °C and down to −30 °C and pressures exceeding 100 MPa. Their distribution in these environments is closely correlated with that of their extremophile hosts, which are mostly bacteria, archaea,

The Extraterrestrial Environment an Axiological Perspective [PDF]
Through human exploration the extraterrestrial space becomes more and more the subject of an anthropological debate. The purpose of this article is to connect axiological thinking with the ethics of human activities related to space exploration. In this context, when debating upon the ability of natural objects to possess value, the distinction between

Simulating microbial processes in extraterrestrial, aqueous environments [PDF]
Finding evidence of life elsewhere in the Solar System is dependent on understanding biotic processes that could occur within potentially habitable environments. Here, we describe a suite of high-pressure flow-through reactors that have been developed to investigate biotic and abiotic processes within simulated sub-surface martian and icy moon ...

Low Energy Subsurface Environments as Extraterrestrial Analogs [PDF]
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 ...

Fire Safety in Extraterrestrial Environments [PDF]
Despite rigorous fire-safety policies and practices, fire incidents are possible during lunar and Martian missions. Fire behavior and hence preventive and responsive safety actions in the missions are strongly influenced by the low-gravity environments in flight and on the planetary surfaces.

Gas-phase prebiotic chemistry in extraterrestrial environments [PDF]
AbstractA variety of molecular species up to complex polyatomic molecules/radicals have been identified in many extraterrestrial gaseous environments, including interstellar clouds, cometary comae and planetary atmospheres. Amongst the identified molecules/radicals, a large percentage are organic in nature and encompass also prebiotic molecules ...

Self-Sustaining Living Habitats in Extraterrestrial Environments
Standard definitions of habitability assume that life requires the presence of planetary gravity wells to stabilize liquid water and regulate surface temperature. Here, the consequences of relaxing this assumption are evaluated. Temperature, pressure, volatile loss, radiation levels, and nutrient availability all appear to be surmountable obstacles to ...

Microbial supplements for extraterrestrial environments
In 2025, the Artemis II marks the first crewed mission orbiting the Moon, with plans for subsequent missions landing astronauts near the lunar South Pole and NASA aims to reach Mars by the 2030s. The growing interest in space underscores the increasing importance of long-term human presence in space missions.

Habitable planetary environments and extraterrestrial life [PDF]
Arguably one of the most important discoveries in the history of human being is the detection of a planet orbiting a main sequence star beyond the solar system. By the time Science celebrated its 125th anniversary, ~150 exoplanets have been discovered. However, there was no known habitable exoplanet.
