MEGASIM: Distribution and Detection of Earth Trojan Asteroids

The Astrophysical Journal
Using N -body simulation results from the MEGASIM data set, we present spatial distributions of Earth Trojan Asteroids and assess the detectability of the population in current and next-generation ground-based astronomical surveys.

Assessing Potential Landing Sites With Favorable Illumination and Accessible, Potentially Volatile‐Rich Permanently Shadowed Regions Within Artemis Candidate Landing Regions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The lunar south pole features permanently shadowed regions (PSRs) that never receive direct sunlight. These regions maintain cold temperatures that potentially trap and accumulate volatiles over geologic timescales. Within NASA's Artemis candidate landing regions, we identified 130 candidate landing sites (CLSs) that satisfy the Human Landing ...

Enantioselective three-dimensional high-performance liquid chromatographic determination of amino acids in the Hayabusa2 returned samples from the asteroid Ryugu

Journal of Chromatography Open
The chirality of amino acids in extraterrestrial materials may provide an insight into the origin of the essential l-enantiopure amino acids in the terrestrial biosphere.

The Magnetic Signature of Stress in Rocks

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Magnetic signatures preserved in rocks have long provided insight into Earth's evolution, revealing processes from plate tectonics to the habitability of Earth. While large impacts are known to impose extreme stresses (>1 GPa) and heat that fundamentally alters magnetic records, lower stresses typical of earthquakes have been considered ...

Radar Circular Polarization Ratio of Near-Earth Asteroids: Links to Spectral Taxonomy and Surface Processes

The Planetary Science Journal
The radar circular polarization ratio (CPR) is an indicator of near-surface, wavelength-scale complexity. Interestingly, previous surveys also noted an association between near-Earth asteroid (NEA) disk-integrated CPR and spectral taxonomic class ...

Accretion and Uneven Depletion of the Main Asteroid Belt

The Planetary Science Journal
The main asteroid belt (MAB) is known to be primarily composed of objects from two distinct taxonomic classes, generically defined here as S- and C-complex.

Peaky Finders: Characterizing Double-peaked Type IIb Supernovae in Large-scale Live-stream Photometric Surveys

The Astrophysical Journal
We present the first photometric population study of double-peaked Type IIb supernovae (SNe IIb). SNe IIb are produced from the core collapse of massive stars whose outermost hydrogen layer has been partially stripped prior to explosion.

CubeSat 3U-payload for in-situ resource utilisation demonstration at C-type near Earth asteroids

, 2018
payloads capable of performing cost effective early stage in situ demonstrations of key steps for various types of ISRU. Such demonstrations would be proof-of-concept and de-risking exercises that would enable future pilot scale and eventually full-scaled implementations.This presentation will focus on a systems design for a 3U payload to demonstration
