VANDENBERG AIR FORCE BASE, Calif., Jan 17 (Reuters) - A SpaceX Falcon 9 rocket blasted off from California on Sunday to put a climate-monitoring satellite into orbit, NASA said.

Technology entrepreneur Elon Musk's SpaceX then planned to attempt to land the rocket on a barge in the Pacific Ocean, which would mark its second milestone a month after it nailed a spaceflight first with a successful ground landing in Florida. (Reporting by Letitia Stein; Editing by Alan Crosby)
