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

Experimental Physiology, EarlyView.
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 ...

ULF Wave Modulation of Energetic Electron Precipitation Caused by the Self‐Limiting of Space Radiation: May 2024 Superstorm Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The May 2024 geomagnetic superstorm provided the opportunity to explore how strong wave‐particle interactions affect energetic electron precipitation under intense driving. Using coordinated measurements from a balloon‐borne Timepix‐based X‐ray detector, ground‐based riometers and magnetometers, and Arase satellite observations, we identified ...

Using an Ellipsoid Model to Track and Predict the Evolution and Propagation of Coronal Mass Ejections

, 2012
We present a method for tracking and predicting the propagation and evolution of coronal mass ejections (CMEs) using the imagers on the STEREO and SOHO satellites.

Why Coronal Mass Ejections Arrive Differently: Solar Cycle Modulation Through Solar Wind Structure

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Coronal Mass Ejections (CMEs) are large structures of magnetized plasma ejected from the Sun's atmosphere into the heliosphere. The interaction of CMEs with the ambient solar wind during propagation affects arrival time and speed at Earth. Since the solar wind structure changes with the solar cycle, variability in the transit times and arrival

Evolution of a Coronal Mass Ejection with an Eruptive Prominence from the Corona to Interplanetary Space

The Astrophysical Journal
Understanding the location and evolution of the cool dense prominence in relation to the large-scale structure of coronal mass ejections (CMEs) is critical to distinguish between different CME initiation mechanisms and to further deepen our understanding

Eruptive Event Generator Based on the Gibson-Low Magnetic Configuration [PDF]

, 2017
Coronal Mass Ejections (CMEs), a kind of energetic solar eruptions, are an integral subject of space weather research. Numerical magnetohydrodynamic (MHD) modeling, which requires powerful computational resources, is one of the primary means of studying ...

Interacting Coronal Mass Ejections and Solar Energetic Particles [PDF]

The Astrophysical Journal, 2002
We studied the association between solar energetic particle (SEP) events and coronal mass ejections (CMEs) and found that CME interaction is an important aspect of SEP production. Each SEP event was associated with a primary CME that is faster and wider than average CMEs and originated from west of E45°.

A New Phase for Space Weather

Space Weather, Volume 24, Issue 4, April 2026.
Abstract As we move into the declining phase of solar cycle 25, the sunspot number is going down but space weather impacts are not disappearing. Solar energetic particle events, large x‐ray flares, and geomagnetic storms are still happening and the declining phase will bring a different balance of hazards.

Impact of Solar Irradiance on Storm‐Time Thermospheric Mass Density Response

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract As a key parameter in the externally forced ionosphere–thermosphere (IT) system, mass density response to storms is affected by the prevailing solar irradiance. To better understand this relationship, we examine mass density responses to the same storm but with different background solar irradiance levels.
