Satellite operators face challenges when hardware fails, leading to old satellites being abandoned or causing space debris. European engineers are developing robotic mechanics for satellite maintenance, aiming for a proof-of-concept mission in 2028. The project includes a robotic arm for refueling and repairs. Legal and market uncertainties exist, but the demand for on-orbit servicing is growing, especially in geostationary orbit. Companies like ExoTrail and ClearSpace are working on solutions for satellite servicing and debris removal, with advancements expected by 2030.
