Strong winds delay Spacex launch of US military satellite

Elon Musk's SpaceX scrapped Saturday's launch of a long-delayed navigation satellite for the U.S. military due to strong upper-level winds. The next launch attempt will be on Sunday at 8:51 a.m. EST/ 13:51 UTC, according to Space X officials.

The launch would have been the rocket firm's first national security space mission for the United States.
