Advanced Science, EarlyView.How can humanity achieve lunar self‐sufficiency? We utilize Au topology networks to modify the abundant lunar ilmenite. This catalyst, under sunlight, can convert waste carbon dioxide into space fuel. This design leverages the moon's natural vacuum for green manufacturing, avoiding the waste of gold and serving as “artificial chloroplasts” to sustain ...

Self-Sustaining Living Habitats in Extraterrestrial Environments
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 ...

Perspectives on Extraterrestrial Civilizations
, 2021 In this study we are interested in variables that predict the degree to which someone believes that extraterrestrial (alien) civilizations exist, and also the degree to which they support efforts to discover extraterrestrial ...

Spontaneous Cyclic Levitation of Glycerol‐Water Droplets at Low Pressures
Advanced Science, EarlyView.Under low pressure, a minute glycerol addition transforms the chaotic dynamics of freezing water droplets into cyclic levitation. Freeze‐concentration preserves liquid pathways that relax expansion‐induced stress, while freezing point depression weakens asymmetric vaporization recoil.

Universal Biosignatures for the Detection of Life [PDF]
, 2005 My goal is to identify processes of life that leave measurable effects on an organism's environment, but which are not tied to any particular biochemistry, in order to build a conceptual framework for the search for extraterrestrial life.
