Solvent constraints for biopolymer folding and evolution in extraterrestrial environments. [PDF]
We propose that spontaneous folding and molecular evolution of biopolymers are two universal aspects that must concur for life to happen. These aspects are fundamentally related to the chemical composition of biopolymers and crucially depend on the solvent in which they are embedded. We show that molecular information theory and energy landscape theory

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 ...

DEM simulation of soil-tool interaction under extraterrestrial environmental effects [PDF]
In contrast to terrestrial environment, the harsh lunar environment conditions include lower gravity acceleration, ultra-high vacuum and high (low) temperature in the daytime (night-time).

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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.

Ethics and the potential conflicts between astrobiology, planetary protection and commercial use of space [PDF]
A high standard of planetary protection is important for astrobiology, though the risk for contamination can never be zero. It is therefore important to find a balance.

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

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 ...
