Knowing about the diversity of planetary processes is of paramount importance for understanding our planet Earth. An integrated, comparative planetology approach is required to combine space missions, autonomous surface exploration, sample return laboratories, and after-mission data exploitation.

'Myriam Telus' 'Jonathan J. Fortney'] Title: Significance Astronomers will soon begin searching for biosignatures, atmospheric gases or surface features produced by life, on potentially habitable planets. Since methane is the only biosignature that the James Webb Space Telescope could readily detect in terrestrial…

'J. F. Bell' 'C. E. Detelich' 'Kirby Runyon' 'M. E. Summers'] We argue that taxonomical concept development is vital for planetary science as in all branches of science, but its importance has been obscured by unique historical developments. The literature shows that the concept of planet developed by scientists during…

> Exoplanet surveys have confirmed one of humanity's (and all teenagers') worst fears: we are weird. If our Solar System were observed with present-day Earth technology – to put our system and exoplanets on the same footing – Jupiter is the only planet that would be detectable. The statistics of exo-Jupiters indicate…

Electromagnetic (EM) sounding of planetary bodies other than the Earth was first possible on the Moon, but has since been used to probe interior structure of planets and moons throughout the solar system. This emergence has been facilitated by the growing availability of mission data and associated improved…

'Steven J. Desch' 'Jonathan Horner' 'N. R. Izenberg' 'K. E. Mandt' 'Victoria Meadows' 'L. C. Quick'] Over the past several decades, thousands of planets have been discovered outside of our Solar System. These planets exhibit enormous diversity, and their large numbers provide a statistical opportunity to place our…

> Abstract: Our understanding of the processes that are relevant to the formation and maintenance of habitable planetary systems is advancing at a rapid pace, both from observation and theory. The present review focuses on recent research that bears on this topic and includes discussions of processes occurring in…

The concept of the origin of life implies that initially, life emerged from a non-living medium. If this medium was Earth’s geochemistry, then that would make life, by definition, a geochemical process. The extent to which life on Earth today could subsist outside of the geochemistry from which it is embedded is poorly…

Title: Significance Sub-Neptune planets dominate the exoplanet population but have no analogues in the solar system. Sized between Earth and Neptune, the nature of such planets remains uncertain, spanning rocky gas dwarfs, mini-Neptunes, and water worlds, with some potentially capable of harboring habitable conditions.…

This paper presents a proof-of-concept study establishing effectiveness of the Active Plasma Sterilizer (APS) for sterilization in planetary protection. The APS uses Compact Portable Plasma Reactors (CPPRs) to produce surface dielectric barrier discharge, a type of cold plasma, using ambient air to generate and…

Considering the harsh surface conditions on Mars, terrestrial organisms that can survive and remain detectable after exposure to similar conditions provide invaluable models for guiding current and future search-for-life missions. To this end, we evaluated the extremophilic archaeon Acidianus manzaensis grown on…

Two other papers discuss the application of JWST data to problems of keen interest in extrasolar planetary science. Millholland and Winn (9) describe the various dynamical phenomena inherent in exoplanet systems that can be diagnosed with JWST observations. The decay of the orbits of close-in Jupiters, subject to…

We evaluate episodes of biosphere change throughout Earth history and compare them with contemporary and near-future anthropogenic changes, developing the concept of biosphere disruptors – agents that force global-scale macroevolutionary change. Transient disruptors are geologically short-lived agents (mean 8.0×10^5^…

Gas pressurized spacesuits are cumbersome, cause injuries, and make completing tasks efficiently difficult. Decreasing the gas pressure of the spacesuit is an effective method of improving mobility, but reduction in the total spacesuit pressure also results in a higher risk for decompression sickness (DCS). The risk of…

Planetary protection hinges on understanding microbial survival following sterilization procedures, the stressors of space travel, and exposure to extraterrestrial environmental conditions. This study identified 23 fungal strains isolated from NASA-spacecraft assembly cleanrooms, capable of surviving ultraviolet…

Viruses are among the simplest biological entities capable of replication. Their robustness and adaptability make them relevant not only to terrestrial ecosystems but also to astrobiological exploration. As durable entities, they may persist in environments far harsher than those tolerable to cellular life and are…
