Uncertainties in space debris dynamics due to space weather

The increase in Earth-orbiting space debris has been the cause of significant debate over the last decade. More than 29,000 objects larger than 10 cm have been detected in orbit and it is estimated that more than 170 million particles above 1mm populate the near-Earth environment. Potential collisions between active satellites and space debris are thus becoming an increasing threat to space operations. Research into mitigation strategies and debris removal efforts have been plentiful, but accurate knowledge of debris dynamics and prediction of their orbital and attitude motion is crucial for the safety and success of future missions. Many environmental factors affect an orbiting body’s orbit and spin rate, such as aerodynamic drag, solar radiation, and interactions with Earth’s magnetic field. All of these perturbations are highly dependent on disturbances occurring around Earth due to space weather. TO BE CONT’D
