Exploring the Habitability of the Outer Solar System Icy Moons for the Extremotolerant Yeast Rhodotorula frigidalcoholis

open access: yesEnvironmental Microbiology, Volume 28, Issue 2, February 2026.
We investigated the survival of the yeast Rhodotorula frigidalcoholis and analysed its RNA after exposure to icy moon conditions. Our results show how the yeast can tolerate the extreme conditions and performs metabolic functions under the exposure conditions; for example, by halting the cell cycle in order to repair. Created in BioRender.

Binder Jetting of Lunar Regolith: Densification Optimization in Air and Vacuum, and Mechanical Performance Evaluation

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT Binder jetting has emerged as a compelling approach for processing lunar regolith, as it is well‐suited for low‐energy environments and requires lower amounts of organic binder, compared to the competitive technologies. This study investigates the feasibility of binder jetting lunar regolith simulants from micrometric particles, focusing on ...

Simple and effective remediation strategies of Martian perchlorates

open access: yesSoil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Martian surface minerals have abundant perchlorate salts existing in both solid and liquid phases that will impair agricultural operations, biological life‐support systems, and in situ resource utilization due to their toxicity. Thus, simple and effective perchlorate remediation strategies will be necessary for the successful use of Martian ...

Oxychlorine Species on Mars: A Review

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

open access: yesAdvanced Engineering Materials, Volume 27, Issue 22, November 2025.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Progress in Resource Evaluation Using a Handheld Raman Instrument Developed for Astronaut Missions

open access: yesJournal of Raman Spectroscopy, Volume 56, Issue 11, Page 1418-1433, November 2025.
Analogue studies were undertaken using a prototype, handheld Raman spectrometer (developed for astronaut usage on the moon) to collect data that would indicate the presence of water and help develop the technology to search for valuable trace elements (such as lithium and caesium).

Regional Ice‐Depth and Thickness in Phlegra Montes, Mars From Radar Characterization of Glacial Landsystems Using SHARAD

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Morphological analyses of Viscous Flow Features (VFFs) in the mid‐latitude regions of Mars have led to the hypothesis that these landforms are equivalent to debris‐covered glaciers. Phlegra Montes is a 1400‐km‐long mountain range in the northern mid‐latitudes that spans from 30° to 50°N, where there is an abundance of glacial landsystems ...

Geologic History of the Mons Malapert and Mons Mouton Regions Near the Lunar South Pole: Basis for Future Exploration

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract This study presents a 1:100,000 scale geologic map of the region encompassing Mons Mouton, Mons Malapert, and Cabeus crater, highlighting the region's geologic diversity. Based on location and topography, Mons Mouton and Mons Malapert are interpreted as remnant massifs of the South Pole‐Aitken (SPA) basin rim.

Analysis of four Apollo 16 double drive tubes using QEMSCAN® mapping techniques: Implications for sampling the lunar regolith in highland terrains

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 10, Page 2504-2523, October 2025.
Abstract The lunar regolith contains a rich history of Solar System impact events and solar activity. Many future missions will land in the south polar region of the Moon, a heavily impact cratered highland terrain, similar to the Apollo 16 landing site.

Origins of the Water Ice Excavated by the Christmas Eve Crater Formation on Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract On the 24th of December 2021, a meteoroid struck the martian surface, producing a 150‐m wide crater and excavating the lowest‐latitude water ice observed on Mars to date. Knowledge of the preimpact depth, thickness and lateral continuity of the excavated ice would provide new insight into past environmental changes such as temperature and ...
