The end of Iridium flares?
An interesting fact is why the name Iridium?<p>When they were in the planning stages for this set of satellites, they estimated that they would need 77 of them to completely cover the Earth (including the poles), evoking an image of 77 electrons circling the nucleus of an atom. The atomic number for the element Iridium is 77. The number of satellites needed was paired down to 66, so the satellites should actually be named Dysprosium.
