VANDENBERG AIR FORCE BASE, Calif. (AP) A SpaceX rocket carrying a Canadian satellite has launched from the California coast in a demonstration flight.

The company says its new and improved Falcon 9 rocket lifted off from Vandenberg Air Force Base on Sunday morning.

SpaceX previously launched an older version of the rocket five times from Florida. The next-generation rocket boasts upgraded engines designed to improve performance and carry heavier payloads.

The rocket is carrying a satellite dubbed Cassiope, a project of the Canadian Space Agency and other partners. Once in orbit, it will track space weather.
