Iridium 125



Coming a month after SpaceX’s last launch, which successfully deployed the US Air Force’s X-37B spaceplane into low Earth Orbit, Monday’s launch was the third of a multi-launch contract between SpaceX and Iridium Communications that will see SpaceX conduct eight missions to deploy seventy-five satellites of Iridium’s second-generation Iridium-NEXT constellation.

Iridium uses a large constellation of spacecraft in low Earth orbit to provide mobile satellite communications worldwide. The first-generation constellation was developed by Iridium SSC, a company financially backed by Motorola.
