Cross‐Referencing Astronaut‐Observed Lunar Impact Flashes With Seismic Data—Lessons From Apollo for Artemis

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract During their orbits of the Moon in 1972, Apollo astronauts reported three impact flashes, associated with meteoroids striking the surface and vaporizing. We examined data from the Apollo seismic network to investigate whether these flashes produced detectable moonquakes whose locations and timing could be independently validated.

Ground Penetrating Radar Observations of Subsurface Structures From the Makgadikgadi Pans (Botswana): A Terrestrial Analogue of Martian Playa Lakes

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...

Spirulina supported plant growth in regolith simulants and elevated levels of CO2

Frontiers in Space Technologies
IntroductionA key element for sustainable off-world habitation is the ability to grow food through in-situ resource utilization (ISRU). Growth substrates are required to overcome the challenges of ISRU in the space environment, including the use of ...

3D Architecture of Kodiak Butte as Evidence of Fluvial or Shoal‐Water Environments in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 mission has explored depositional environments recorded in a fan‐shaped deposit on the western side of Jezero crater. Kodiak butte is an isolated outcrop of sedimentary rock ∼1 km south of the western fan scarp and may be an erosional remnant of said fan.

Coupled Effects of Grain Size and Metallic Iron on Spectral and Polarimetric Properties of Lunar Simulants

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The lunar surface is heterogeneous in grain size and metallic iron abundance due to diverse histories of space weathering. The spectral and polarimetric properties of the lunar regolith are strongly affected by both grain size and metallic iron particles.

Structural Analysis of Lunar Regolith from LPR CH-2 Data Based on Adaptive f-x E MD: LPR Data Processed by Adaptive f-x EMD

Advances in Astronomy, 2019
The Lunar Penetrating Radar (LPR) is one of the important scientific payloads in China’s Chang’E-3 (CE-3) to image within 100 m below the lunar surface. The acquired LPR data is significant for the research of lunar geological structure.

The Effects of ICME Composition on the Sputtered Component of the Lunar Exosphere

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Charged‐particle sputtering is a fundamental process that contributes to the generation of the Moon’s neutral exosphere. Neutral sputtering rates are dependent on the speed, flux, and composition of the incident charged‐particle populations, all of which are variable at the Moon’s orbit.

Ancient Impact Melt Near the Lunar South Pole: Distribution, Provenance, and Sampling Strategy

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Due to a lack of pre‐Nectarian samples associated with specific impacts in the Apollo suite, the early Solar System's impact chronology is poorly constrained. We investigate where Artemis and other south polar lunar missions could sample impactites to determine the ages of pre‐Nectarian craters, focusing on the ancient craters Haworth ...

Coseismic Shallow Landslide Distributions Reveal Patterns of Regolith Thickness in High Mountains

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Earthquake‐triggered landslides are a major source of sediment mobilization in steep mountain landscapes, yet the controls that organize regional patterns of coseismic shallow failure remain incompletely understood. Because shallow landslides occur within regolith, their initiation and magnitude depend strongly on near‐surface material ...
