Michigan Geospace Model With Ensemble Forecasting and Particle Filtering: Modeling the May 2024 Extreme Storm

open access: yesSpace Weather, Volume 24, Issue 9, September 2026.
Abstract This paper introduces an updated version of the University of Michigan Geospace model. The Geospace model has been used for operational forecasting at the Space Weather Modeling Center of the National Oceanic and Atmospheric Agency since 2016 with regular updates. The current operational version, Geospace V2, was launched in 2021 and is driven

Magnetosphere

open access: yesEos, Transactions American Geophysical Union, 1991
Research on the terrestrial magnetosphere, above 500 km, continues to focus on how energy gets from the solar wind into the magnetosphere and how it circulates through the magnetosphere. The prime candidate for energy coupling has long been magnetic merging in which the magnetic field that the solar wind carries from the Sun merges with the geomagnetic

Cross‐Correlations of Solar Wind Parameters Using Monitoring Spacecraft

open access: yesSpace Weather, Volume 24, Issue 9, September 2026.
Abstract Space weather predictive modeling currently utilizes real‐time data from the spacecraft ACE and DSCOVR, with SOLAR‐1 and IMAP recently online. This study assesses whether DSCOVR solar wind plasma and interplanetary magnetic field (IMF) data exhibit large‐scale discrepancies from the corresponding ACE data, and if so, whether these ...

Robust Short‐Term Forecasting of Thermospheric Density and Orbit Prediction Using an Interpretable iTransformer Model

open access: yesSpace Weather, Volume 24, Issue 9, September 2026.
Abstract Accurate short‐term forecasting of thermospheric mass density is crucial for satellite operations. However, achieving high‐precision predictions remains a significant challenge. In this study, we develop an iTransformer framework that forecasts thermospheric density over the next 24 hr using observations from the preceding 24 hr. Using density

Magnetosphere

open access: yesEos, Transactions American Geophysical Union, 1971
This report on progress in the magnetosphere covers the calendar years 1967–1970 inclusive. Bibliographical coverage is also for the period 1967–1970: therefore, results presented at conferences but not yet available in published form may be cited.The topic of the magnetosphere has been divided into five sections: magnetopause; magnetosphere structure,

Personalization and Fortification of In‐Space Manufactured Emulsified Beverages for Long‐Term Space Travel

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT The current trend of individualized food items (nutrient content and flavor) can be particularly valuable to support people's health and well‐being in isolated environments where access to fresh foods and diverse nutrition is difficult. At the same time, bioactive compounds and micronutrients can be employed to countermeasure any health ...

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 3919-3927, 1 September 2026.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.

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

open access: yesExperimental 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 ...

Solar wind ion charge state distributions and compound cross sections for solar wind charge exchange X-ray emission

open access: yesEarth and Planetary Physics
Solar Wind Charge eXchange X-ray (SWCX) emission in the heliosphere and Earth's exosphere is a hard to avoid signal in soft X-ray observations of astrophysical targets.

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

open access: yesGeophysical 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.
