Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization
Advanced Materials Interfaces, EarlyView.Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

How Rare Are Extraterrestrial Civilizations and When Did They Emerge? [PDF]
, 1998 It is shown that, contrary to an existing claim, the near equality between the lifetime of the sun and the timescale of biological evolution on earth does not necessarily imply that extraterrestrial civilizations are exceedingly rare. Furthermore, on the

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

Tough and Temperature‐Resistant Material Based on Bombyx mori Silk Fibroin
Advanced Science, EarlyView.We propose a biomimetic “Hydration‐Crystallization Locking” (HCL) strategy inspired by Bombyx mori spinning to enhance silk fibroin (SF) performance in extreme temperatures. A flexible fibroin membrane (FFM) shows high strength, toughness, and shape retention under −196°C and 70°C.

Resistance ofBacillusEndospores 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
