Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight

Rapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.
ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.

Slope Stability Analysis and Soil Mechanical Properties of Impact Craters around the Lunar South Pole

Remote Sensing
Water ice has been found in the permanently shadowed regions of impact craters around the lunar South Pole, which makes them ideal areas for in situ exploration missions.

Spectral interpretation of late-stage mare basalt mineralogy unveiled by Chang’E-5 samples

Nature Communications, 2022
Laboratory spectroscopic and X-ray diffraction analyses on the Chang’E-5 lunar soil samples have demonstrated that the spectral features of lunar late-stage mare basalts are representative of iron-rich high-Ca pyroxene rather than olivine.

Bottom‐Up Space Use With Top‐Down Temporal Risk Buffering in Arid Herbivore Communities

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Across seven large herbivore species in an unfenced arid system, space use is governed by bottom‐up constraints while predator risk is buffered in time, producing consistent low diel overlap with nocturnal carnivores and trait‐dependent moderation of spatial responses.

Effect of Soil Type on Running Performance of Small Lunar Rover

Aerospace
It is very easy for a small lunar rover to slip on the regolith of the lunar surface and become stuck. Previous studies have quantitatively evaluated the effects of wheel geometry, such as elliptical or eccentric wheels, on the performance of a rover ...

Beyond Exponential Decay: How Biphasic and Delayed Decay Dynamics Shape Marine eDNA Dispersal

Ecology and Evolution, Volume 16, Issue 1, January 2026.
We used a multiprong approach with a literature review of eDNA decay experiments, an experimental study of empirical decay patterns, and high‐resolution Lagrangian particle tracking to quantify how different decay patterns drive eDNA dispersal at two contrasted locations in the Bay of Biscay, Northeast Atlantic.

The Effect of Tip Design on Technological Performance During the Exploration of Earth, Lunar, and Martian Soil Environments

Journal of Field Robotics, Volume 43, Issue 1, Page 387-408, January 2026.
ABSTRACT This paper investigates the penetration performance of soil‐burrowing probes with different tip designs during shallow‐depth penetration in various media, including terrestrial soils (Hostun sand) and well‐characterized planetary soil simulants (LHS‐1 Lunar regolith simulant and MGS‐1 Martian regolith simulant).

Implantation of Earth's Atmospheric Ions Into the Nearside and Farside Lunar Soil: Implications to Geodynamo Evolution

Geophysical Research Letters, 2020
Earth's present dipolar magnetic field extends into the interplanetary space and interacts with the solar wind, forming a magnetosphere filled up with charged particles mostly originating from the Earth's atmosphere.
