The first discovery of a shocked, metasomatised CV3 chondrule‐fragment in a (Al,Cu)‐bearing micrometeorite

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2269-2283, September 2026.
Abstract We report the discovery of the second (Al,Cu)‐alloy–bearing micrometeorite, FB‐A2, recovered from Mount Gariglione (southern Italy), representing the sixth such occurrence worldwide. Although chondritic in nature, FB‐A2 differs markedly from previously described microspherules.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Controls on Solar Wind Entry Identified Through Wind–ACE Heavy‐Ion Diagnostics

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Solar wind (SW) entry into the magnetosphere occurs through several mechanisms, but their dependence on the properties of different ion species is unknown. We compare measurements from Wind‐STICS (magnetosphere) with ACE‐SWICS (L1) to test for any preferential entry between He2+ and SW heavy ions.

Propagation of Interplanetary Shocks in the Heliosphere

, 2023
Interplanetary shocks are one of the crucial dynamic processes in the Heliosphere. They accelerate particles into a high energy, generate plasma waves, and could potentially trigger geomagnetic storms in the terrestrial magnetosphere disturbing significantly our technological infrastructures. In this study, two IP shock events are selected to study the

Variations of Mid‐Magnetotail Magnetic Pressure During Substorms

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Magnetic reconnection is commonly observed in the mid‐tail plasma sheet during substorms, the mechanism behind this spatial preference, however, remains unsolved. This study focuses on magnetic pressure evolution within this critical region during substorms.

Spiky Bursts of Energetic Electron Beams Upstream of Nonstationary Quasi‐Perpendicular Shocks

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Energetic electron beams play a crucial role in collisionless shocks by driving upstream plasma waves and providing seed populations for diffusive shock acceleration. However, the processes responsible for their generation at quasi‐perpendicular shocks remain poorly understood.

Computations on the interaction of an interplanetary shock with the Earth's magnetosphere

Astrophysics and Space Science, 1977
We present the results of a one-dimensional computer simulation of the interaction between interplanetary shocks and the Earth's magnetosphere. The position of the bowshock as a function of solar wind velocity and interplanetary field direction is studied.

Predicting the Arrival Time of an Interplanetary Shock Based on DSRT Spectrum Observations for the Corresponding Type II Radio Burst and a Blast Wave Theory

The Astrophysical Journal
Since fast head-on coronal mass ejections and their associated shocks represent potential hazards to the space environment of the Earth and even other planets, forecasting the arrival time of the corresponding interplanetary shock is a priority in space ...
