Live coverage: Ariane 5 rocket deploys satellites for Australia, India

United Launch Alliance ground crews are putting the final touches on a Delta 4 rocket scheduled for blastoff Friday evening from Cape Canaveral with a U.S. Air Force communications satellite.

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.

Riding on its side aboard a rail car, a Proton rocket trekked to its launch pad Tuesday at the Baikonur Cosmodrome in Kazakhstan with a Eutelsat television broadcast satellite ready for liftoff Friday.
