Live coverage: Two satellites blast off on Ariane 5

Iridium chief executive Matt Desch spoke with Spaceflight Now on the eve of the first launch for the company’s next-generation satellite fleet, discussing the $3 billion upgrade’s technical and financial ramifications and his feelings before deployments begin in orbit.

A commercial communications satellite will blast off Thursday from French Guiana on top of a Soyuz rocket, on the way to a station over the Americas to supply bandwidth to airline travelers and broadcasters in the United States, Canada and Mexico.

Armed with $460 million in fresh financing to grow its broadband communications capacity, O3b Networks has selected Thales Alenia Space to build eight new satellites and Arianespace to launch at least four of them aboard a Soyuz rocket in 2018.
