This dimension marks whether a spacecraft is still active, retired or lost. Wikipedia notes that most spacecraft "are designed to deorbit themselves" at the end of their working life, while some, like failed upper stages, remain derelict in orbit instead. Browsing by status separates spacecraft still operating from those no longer in service.
