Premature Reentry of the Binar CubeSats Due To Underestimation of Solar and Geomagnetic Activities and Its Implication for Importance of Medium‐ and Long‐Term Space Weather Forecasts

Space Weather, Volume 23, Issue 12, December 2025.
Abstract The rapid development of low‐Earth orbit (LEO) satellites brings increased attention to spacecraft collisions, space debris, orbital decay, and satellite reentry. Neutral density and associated drag force on the satellite orbits elevate space risks, significantly determined by space weather disturbances, particularly geomagnetic storms.

On the possibility of determining the parameters of the ionosphere when removing a nanosatellite from orbit using an uninsulated conductive tether

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение
Currently, one of the ways to quickly remove spent nanosatellites from orbit is the use of non-insulated conductive tether, during the movement of which an electrodynamic braking force arises in the Earth's magnetic field, transferring the nanosatellite ...

Analyzing SEU Rate in LEO Satellites During the Space Weather Event of May 2024

Space Weather, Volume 23, Issue 11, November 2025.
Abstract From 10 to 12 May 2024, Earth experienced the most intense geomagnetic storm in two decades. Using observational data from the Fengyun‐3E satellite (FY‐3E) and the empirical formula for single event upset (SEU), we investigate the proton flux distribution in both the South Atlantic Anomaly (SAA) and high‐latitude regions, as well as the ...
