Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Experimental Hypervelocity Dust Impacts in Olivine—Multiscale Insights Into Microcrater Shock and Melting Effects From Coordinated SEM/TEM Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

Body, Mind, and Emotion: Multi‐Sited Labour of Social Reproduction and Gendered Experiences of Rural Migrants from the Mekong Delta

Antipode, Volume 58, Issue 2, March 2026.
Abstract In the context of global market integration, capital accumulation relies on social reproduction; yet unlimited accumulation disrupts the reproductive processes that sustain it. Vietnam is pursuing economic growth in the same fashion, relying on cheap migrant labour in urban areas that are stabilising rural areas through remittances and care ...

Apatite in Bennu samples indicates multiple stages of aqueous alteration

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 504-521, March 2026.
Abstract Calcium phosphates are ubiquitous in planetary materials, including samples returned from asteroid Bennu by the OSIRIS‐REx mission. We characterized apatite [Ca5(PO4)3(F,Cl,OH)] grains in Bennu samples by scanning electron microscopy, electron microprobe analysis, and transmission electron microscopy to investigate their compositions, mineral ...

Planetary Formation Constrained by Collisions between Millimeter-sized Lunar Particles and Lunar Surface from Chang’E-4 Mission

The Astrophysical Journal
Exploring low-velocity collisions is crucial for unraveling intricate processes in planetary formation, particularly the bouncing barrier that impedes the aggregation of dust into sizable planetesimals.

Lunar dust induces minimal pulmonary toxicity compared to Earth dust

Life Sciences in Space Research
Humans are returning to the moon and understanding the toxicity of lunar dust is crucial for successful missions. Apollo mission reports suggest that lunar dust poses significant inhalation risks. Previous studies on lunar dust simulants have shown tissue and cellular damage in the lungs.

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 351-370, March 2026.
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...
