After launch, 23272 2002-005A was labelled as Iridium 90 and 23273 2002-005B was labelled as Iridium 91. However, Spacecom exchanged the labelling of Iridium 90 and Iridium 91 on January 1, 2006. This evidently addressed a long-standing mislabelling of these objects to bring the designations in line with those used by the operators of the Iridium system. There have been other such exchanges of names of members of the Iridium constellation at various dates. More information on my Iridium pages at http://www.rod.sladen.org.uk/iridium.htm I hope this is useful! ...
