Iridium 174, one of 66 satellites in a mesh network built from the ashes of one of the space industry's most dramatic bankruptcies — the original Iridium constellation cost $5 billion and collapsed within a year of its 1998 launch, before finding new life as the only satellite phone network offering genuine pole-to-pole coverage, relaying calls satellite-to-satellite without ever needing a nearby ground station.
