Last flight of the Titan

Returning to service after a six-year hiatus, Orbital ATK’s revamped Minotaur-C rocket soared into space Tuesday from California’s Central Coast with 10 commercial Earth-imaging spacecraft for Planet, a San Francisco-based company with a globe-spanning satellite fleet mapping the world’s land masses every day.

On the eve of the Iridium’s fifth launch with SpaceX, the mobile telecom satellite operator’s chief executive says he no longer waits for SpaceX’s rockets to be ready. Instead, Iridium’s satellite team is racing to keep pace churning spacecraft off their assembly line.

Ten more satellites for Iridium’s upgraded voice and data communications fleet rode a SpaceX Falcon 9 rocket into a nearly 400-mile-high orbit from California’s Central Coast Monday.
