A solid-fueled Kuaizhou 1A launcher carried a commercial broadband communications satellite into orbit Thursday for Galaxy Space, a Chinese company that says it plans to launch up to 144 spacecraft for a space-based 5G network in the next few years.

Arianespace’s third Ariane 5 launch of the year was set liftoff Friday from Kourou, French Guiana, but an issue with a sensor on the rocket’s first stage liquid hydrogen tank caused officials to scrub the launch attempt. The Ariane 5 is poised to carry three U.S.-built commercial satellites into orbit, while testing a few rocket upgrades, including a modified fairing needed for the launch of the James Webb Space Telescope next year.

Follow the Atlas 5 rocket’s ascent into orbit from Cape Canaveral’s Complex 41 launch pad with the U.S. Air Force’s GPS 2F-12 navigation satellite. Launch is scheduled for Friday at 8:38 a.m. EST (1338 GMT).
