Self-sustaining living habitats in extraterrestrial environments [PDF]
AstrobiologyStandard 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 ...

Mini-Review: Probing the limits of extremophilic life in extraterrestrial environment-simulated experiments [PDF]
International Journal of Astrobiology, 2012 The results obtained in these experiments have revealed a remarkable resistance of extremophilic bacteria and archaea against different radiation sources (VUV, solar wind simulants, X rays) whenever protected by microsized carbonaceus grains. Altogether, the collected data suggest the interesting possibility of the existence of microbial life beyond ...

The Extraterrestrial Environment an Axiological Perspective [PDF]
LUMEN Proceedings, 2017 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

Fire Safety in Extraterrestrial Environments [PDF]
Space 98, 1998 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]
Proceedings of the International Astronomical Union, 2009 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 ...

Resistance of Bacillus Endospores to Extreme Terrestrial and Extraterrestrial Environments [PDF]
Microbiology and Molecular Biology Reviews, 2000 SUMMARYEndospores of Bacillus spp., especially Bacillus subtilis, have served as experimental models for exploring the molecular mechanisms underlying the incredible longevity of spores and their resistance to environmental insults. In this review we summarize the molecular laboratory model of spore resistance mechanisms and attempt to use the model as

Proprioceptive Slip Detection for Planetary Rovers in Perceptually Degraded Extraterrestrial Environments [PDF]
, 2022 Slip detection is of fundamental importance for the safety and efficiency of rovers driving on the surface of extraterrestrial bodies. Current planetary rover slip detection systems rely on visual perception on the assumption that sufficient visual features can be acquired in the environment.
