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

Journal 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).

Thermodynamic model of Mars Oxygen ISRU Experiment (MOXIE) [PDF]

Acta Astronautica, 2016
Abstract As humankind expands its footprint in the solar system, it is increasingly important to make use of the resources already in our solar system to make these missions economically feasible and sustainable. In-Situ Resource Utilization (ISRU), the science of using resources at a destination to support exploration missions, unlocks potential ...

AI‐driven preoperative risk assessment in kidney cancer surgery: A comparative feasibility study of machine learning models

BJUI Compass, Volume 6, Issue 10, October 2025.
Abstract Background and Objective Preoperative risk stratification in renal tumour surgery is essential to enable risk‐adjusted postoperative patient monitoring. Machine learning (ML) models predicting major complications (MCs) and acute kidney injuries (AKIs) following partial (PN) or radical nephrectomy (RN) have not been made, nor have they been ...

Earth's Minimoons: Opportunities for Science and Technology

Frontiers in Astronomy and Space Sciences, 2018
Twelve years ago the Catalina Sky Survey discovered Earth's first known natural geocentric object other than the Moon, a few-meter diameter asteroid designated 2006 RH120. Despite significant improvements in ground-based telescope and detector technology

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

Journal 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

Journal 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

Meteoritics &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

Journal 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 ...

Characterization of High-priority Landing Sites for Robotic Exploration Missions in the Apollo Basin, Moon

The Planetary Science Journal
The South Pole–Aitken (SPA) basin is the oldest and largest visible impact structure on the Moon, making it a high priority science site for exploration missions. The 492 km diameter Apollo peak-ring basin is one of the youngest and largest basins within
