    Quote from http://www.rod.sladen.org.uk/iridium.htm Nov.22 2012 :
    
    "In late July 2012, Iridium 51 (25262, 1998-018A). which had been out
    of the operational constellation for many years, was moved in the
    postion previously occupied by Iridium 7 (24793, 1997-020B), while
    Iridum 7 was moved to follow slightly behind it. The two satellites
    are each providing some of the functionality for the given slot.
    Orbital Plane 4 has no other spare satellite."
    
    The latest five elsets show that they have extremely similar mean
    motions, Ir7 oscillating 14.342167-14.342202 but Ir51 very stable near
    14.342177.
    
    So they should be close until a failure will force them to separate.
