Discussion

Analysis reveals geomagnetic storms caused premature reentry in Binar satellites, highlighting gaps in space weather forecasts.

Premature reentry due to underestimation of solar activity led to substantial lifespan reduction in the Binar satellites.
In 2024, Binar-2, 3, and 4 satellites experienced lifetimes only about 20% of the expected duration.
Study involved examining medium- and long-term space weather forecasts to assess their accuracy and implications.
Findings underscore the critical nature of accurate space weather forecasting for LEO satellite design and operation.

Wang et al. (2025) studied this question.
