defunct satellites

Defunct satellites are communication or observation satellites that have completed their mission, lost power, or become non-functional. They remain in orbit around Earth but no longer serve any purpose. These satellites can be considered space debris, potentially posing collision risks for active spacecraft. While some defunct satellites are decommissioned intentionally and moved to a 'graveyard' orbit, others are left in orbit after failure or end of life. Managing this space debris is important to ensure the safety and sustainability of current and future space activities.
