Keeping a spare on hand simply makes sense. Just as drivers keep spare tires on hand to replace a flat or blowout, NASA routinely maintains "spares," too. These flight hardware backups allow NASA to seamlessly continue work in the unlikely event something goes down for a repair. When projects end, these handy spares can sometimes find second lives in new areas for use.
