On-Orbit Servicing & Life Extension

On-orbit servicing encompasses technologies that extend satellite life, repair failures, refuel propellant, and perform inspection in space. The sector is transitioning from technology demonstrations to commercial operations, with the GEO life extension market proving the business case.
