Iridium 143, one of the 66 operational Iridium NEXT satellites providing global mobile satellite phone and data coverage. This satellite is contributing to a constellation built from the ashes of one of the space industry's most dramatic bankruptcies — a $5 billion venture that failed within a year of its 1998 launch, later rebuilt into essential global infrastructure.
