A promising view to the Moon: Anticipations for Tianwen-2 samples returned from Kamo’oalewa

open access: yesEarth and Planetary Physics
The exploration of asteroids has received increasing attention since the 1990s because of the unique information these objects contain about the history of the early solar system. Quasi-satellites are a population of asteroids that co-orbit closely with,

Ferric Chloride: The Venusian Unknown UV Absorber?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Near‐ultraviolet imaging of the planet Venus reveals inhomogeneous absorption features in the otherwise bright clouds. This absorption has been studied for nearly 100 years, but identification of the near‐UV absorber remains one of the largest open questions in Venusian research.

An Earth Encounter as the Cause of Chaotic Dynamics in Binary Asteroid (35107) 1991VH

open access: yesThe Planetary Science Journal
Among binary asteroids, (35107) 1991VH stands out as unique given the likely chaotic rotation within its secondary component. The source of this excited dynamical state is unknown. In this work, we demonstrate that a past close encounter with Earth could

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space

open access: yesThe Modern Law Review, Volume 89, Issue 5, Page 723-759, September 2026.
As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?

open access: yesGlobal Policy, Volume 17, Issue 4, Page 553-565, September 2026.
ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

Magnetic field measurements during the ROSETTA flyby at asteroid (21) Lutetia [PDF]

open access: yes, 2011
On July 10, 2010, the ROSETTA spacecraft performed a flyby at asteroid (21) Lutetia at a solar distance of 2.72 AU. The spacecraftâ  asteroid distance at closest approach was 3120 km.

Direct N-body Simulations of Satellite Formation around Small Asteroids: Insights from DART’s Encounter with the Didymos System

open access: yesThe Planetary Science Journal
We explore binary asteroid formation by spin-up and rotational disruption considering the NASA DART mission's encounter with the Didymos–Dimorphos binary, which was the first small binary visited by a spacecraft.

Bolide light curve systematics from 75 recovered meteorites

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2351-2392, September 2026.
Abstract How does the energy deposition profile (light curve), deceleration, and penetration depth in Earth's atmosphere depend on asteroid composition and meteorite type? Here, we present the light curve and velocity profile of 75 bolides from camera‐documented meteorite falls.

Oxygen isotope variability in the IIIAB iron meteorites and their relationship to main group pallasites

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2393-2405, September 2026.
Abstract The light element distribution in planetary cores and the processes driving core evolution in rocky planets are poorly understood. Magmatic iron meteorites are samples from the cores of ancient embryonic planetesimals and therefore provide a window into the processes governing core evolution. We performed high precision oxygen isotope analyses
