Orbital Transfers in a Binary Asteroid System Considering Flattening of the Bodies and Solar Radiation Pressure

Aerospace
This paper aims to investigate the effects of asteroid size and shape and solar radiation pressure in the trajectories of a spacecraft in transfers between the collinear equilibrium points of a binary non-spherical asteroid system.

The Dynamical Environment of Dawn at Vesta

, 2012
Dawn is the first NASA mission to operate in the vicinity of the two most massive asteroids in the main belt, Ceres and Vesta. This double-rendezvous mission is enabled by the use of low-thrust solar electric propulsion. Dawn will arrive at Vesta in 2011

Occurrence and characterization of nanosulfide‐rich regions on asteroid Ryugu: Insights from mackinawite and pyrrhotite

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 168-181, January 2026.
Abstract Samples returned from asteroid Ryugu by the Hayabusa2 mission are dominated by fine‐grained matrix material made of phyllosilicates and nanosulfides. Here, we report the mineralogical, textural, and chemical characteristics of nanosulfide‐rich regions identified in Ryugu particles.

Catalog of Proper Orbits for 1.25 Million Main-belt Asteroids and Discovery of 136 New Collisional Families

The Astrophysical Journal Supplement Series
The proper elements of asteroids are obtained from the instantaneous orbital elements by removing periodic oscillations produced by gravitational interactions with planets.

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

The 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 ...

Fully Coherent Model of Dynamics around Binary Asteroids: Application to Didymos and the DART Impact

The Planetary Science Journal
The dynamical environment around binary asteroids has been studied in depth, but these models typically make assumptions about the eccentricity, shapes, or rotational stability of the asteroids.

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

Systematic 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.

Geo-engineering using dust grains in heliotropic elliptical orbits [PDF]

, 2011
This paper examines the concept of a Saturn-like Earth ring comprised of dust grains to offset global warming. A new family of non-Keplerian periodic orbits, under the effects of solar radiation pressure and the Earth’s oblateness J2 perturbation, is ...
