The rapid increase in commercial satellites in Low-Earth Orbit (LEO, 200-2000 km altitude) in the last 3 years, as well as the plans for far greater increases in the future, has resulted in the new paradigm of “proliferated LEO” operations. In February 2022 it was demonstrated that space weather can disrupt these operations significantly when 38 SpaceX Starlink satellites were lost due to unexpectedly large thermospheric density increases during a geomagnetic storm. As we approach the maximum of Solar Cycle 25, it is imperative that space weather researchers, forecasters, and satellite operators work together to fully understand the space weather phenomena, forecasting requirements, and impacts to operations that can be expected. As the number of satellites in LEO continues to grow, maintaining safe operations will require improved tracking systems, better collision prediction models, new instruments and missions for improved nowcasting of the orbital environment, and more accurate and timely forecasting models for thermosphere-ionosphere conditions, Solar Energetic Particle (SEP) precipitation, and spacecraft charging. This session welcomes presentations on space weather impacts to LEO satellite operations, plans for new space traffic management tools including the NOAA Office of Space Commerce Traffic Coordination System for Space (TraCSS) and space weather applied research that can lead to improved forecasting and nowcasting of environmental conditions in the LEO space domain.
