A high-power broadband communications satellite designed to provide Internet access to airliner passengers, cruise ships, fishing vessels, and other mobile users successfully launched Thursday aboard a Chinese Long March 3B rocket.

The United Launch Alliance Atlas 5 rocket was rolled to the pad today at Cape Canaveral’s Complex 41 in preparation for Friday’s liftoff. The flight will deliver the Mobile User Objective System satellite No. 5 into orbit, fulfilling a five-launch, four-year effort to assemble the military’s secure smartphone mobile communications network. Launch is scheduled for 10:30 a.m. EDT (1430 GMT).

Concerns about the coronavirus pandemic have prompted officials to postpone the planned March 30 launch of Argentina’s SAOCOM 1B radar observation satellite from Cape Canaveral aboard a SpaceX Falcon 9 rocket, officials said Tuesday.
