Live coverage: SpaceX resumes launches from California

A Russian Proton rocket boosted a Turkish telecommunications satellite into space Friday after a blazing liftoff from Kazakhstan, and a Breeze M upper stage injected the 5.4-ton broadcasting craft into an orbit ranging more than 20,000 miles above Earth nine hours later.

A SpaceX Falcon 9 rocket sporting human-rating upgrades such as new composite pressurant tanks briefly ignited its nine Merlin engines Thursday afternoon on a launch pad at NASA’s Kennedy Space Center in Florida, and SpaceX later declared the pre-launch milestone complete in preparation for a critical test flight with a commercial crew capsule as soon as late February.

A modified Russian missile built for nuclear war blasted off on a peaceful mission Friday, targeting placement of a European Earth observation satellite in orbit to measure atmospheric chemistry and global air quality. Liftoff from the Plesetsk Cosmodrome in northern Russia occurred at 0927 GMT (5:27 a.m. EDT).
