Since the Iridium network discovered they only needed 66 satellites instead of 77 for global coverage, and Iridium was named for the number of protons in the iridium atom, shouldn't they have renamed it to Dysprosium?
Lamp@Elizafox not if theres still 77 sattelites being used

They still have 77 in-orbit (11 planes of 6 satellites + 1 in-orbit reserve) and 15 ground spares...
Because #IridiumNext is a drop-in replacement of #Iridium...
