Very Low Earth Orbit (VLEO) refers to altitudes ranging from the Kármán Line up to approximately 400 km. Interest in VLEO has surged in recent years due to its unique advantages, such as enhanced imaging resolution, improved radar communications, reduced launch and operational costs, and self-cleaning orbits that help mitigate space debris accumulation. However, VLEO environments present considerable challenges for satellite operations. In this region, the high density of atomic oxygen accelerates surface degradation and increases unpredictability from particle impacts. The denser atmosphere relative to LEO also causes substantial aerodynamic drag, leading to complex interactions that remain challenging to model, especially regarding particle re-emission from surfaces.
