Modeling enstatite chondrites: Reduced rocks with a pinch of oxidized material (affected by varying H2O(g)) derived from planetesimals shocked during the epoch of giant–planet migration

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 1, Page 122-139, January 2026.
Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a

The Martyrdom of Nadezhda Kurchenko: Soviet Hero Cults and the Spiritual Turn in Late Socialism

open access: yesThe Russian Review, Volume 85, Issue 1, Page 69-87, January 2026.
Abstract This article argues that the spiritual turn in Soviet atheism under Brezhnev provided a meaningful solution to the problems of producing heroes when self‐sacrificing martyrs were losing their appeal. To support this claim, I examine the story of Nadezhda Kurchenko, a nineteen‐year‐old flight attendant killed by two hijackers on an Aeroflot ...

Optimal trajectory generation for multiple asteroid rendezvous

open access: yes, 2007
This thesis is focused on solving one component of the proposed problem in the Global Trajectory Optimization Competition released by the Jet Propulsion Laboratory in late 2006. The goal is to find an optimal spacecraft trajectory to rendezvous with an asteroid in a group of asteroids.

Deep‐soil sampling in Chile reveals a new elateroid beetle family, Badmaateridae fam. nov. (Coleoptera)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
Genomic data support the definition of a new elateroid family, Badmaateridae fam. nov., with Badmaater chilensis gen. nov. sp. nov. as the only representative. Badmaateridae is sister to an extensive clade containing fireflies, soldier beetles, net‐winged beetles and click beetles.

Delayed‐onset cord1 progressive retinal atrophy in English Springer Spaniels genetically affected with the RPGRIP1 variant

open access: yesVeterinary Ophthalmology, Volume 29, Issue 1, January 2026.
Abstract Objective Cone‐rod dystrophy (cord1) is a form of progressive retinal atrophy. It is linked to an RPGRIP1 genetic variant which is the third most common canine disease variant thus far. While the variant affects various breeds, it is highly prevalent in English Springer Spaniels (ESSs).

Spacecraft and Asteroid Thermal Image Generation for Proximity Navigation and Detection Scenarios

open access: yesApplied Sciences
On-orbit autonomous relative navigation performance strongly depends on both sensor suite and state reconstruction selection. Whenever that suite relies on image-based sensors working in the visible spectral band, the illumination conditions strongly affect the accuracy and robustness of the state reconstruction outputs.
