Mini-Review: Probing the limits of extremophilic life in extraterrestrial environment-simulated experiments [PDF]

open access: greenInternational Journal of Astrobiology, 2012
Astrobiology is a relatively recent scientific field that seeks to understand the origin and dynamics of life in the Universe. Several hypotheses have been proposed to explain life in the cosmic context throughout human history, but only now, technology ...

Proprioceptive Slip Detection for Planetary Rovers in Perceptually Degraded Extraterrestrial Environments [PDF]

open access: greenField Robotics, 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 ...

Self-sustaining living habitats in extraterrestrial environments [PDF]

open access: greenAstrobiology
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 ...

Resistance of Bacillus Endospores to Extreme Terrestrial and Extraterrestrial Environments [PDF]

open access: greenMicrobiology 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

Comet Pond II: Synergistic Intersection of Concentrated Extraterrestrial Materials and Planetary Environments to Form Procreative Darwinian Ponds [PDF]

open access: goldLife, 2018
In the “comet pond” model, a rare combination of circumstances enables the entry and landing of pristine organic material onto a planetary surface with the creation of a pond by a soft impact and melting of entrained ices.

Habitable planetary environments and extraterrestrial life [PDF]

open access: bronzeChinese Science Bulletin, 2016
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.

Simulating microbial processes in extraterrestrial, aqueous environments [PDF]

open access: yesJournal of Microbiological Methods, 2020
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 ...

Solvent constraints for biopolymer folding and evolution in extraterrestrial environments

open access: greenProceedings of the National Academy of Sciences
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
