Live coverage: Vega rocket launches with LISA Pathfinder

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.

SpaceX launched a Falcon 9 rocket at 1:09 p.m. PDT (4:09 p.m. EDT) Wednesday from Vandenberg Space Force Base, California, on a mission hauling 51 more Starlink internet satellites into orbit.

Two weeks after a sensor problem forced a delay, an Ariane 5 rocket blasted off at 6:04 p.m. EDT (2204 GMT) Saturday from French Guiana with two commercial communications satellites to cover the United States and Japan, and a Northrop Grumman-built robotic satellite servicing mission designed to link up with another spacecraft in geostationary orbit.
