The Air Force is warning residents on California's central coast to be prepared for unusual sights and sounds this weekend as SpaceX attempts its first return of a rocket to launch site on the West Coast.

A SpaceX Falcon 9 rocket is scheduled to launch a satellite into orbit from Vandenberg Air Force Base at 7:21 p.m. Saturday.

The Falcon's first stage will then fly back to Vandenberg and set down in a landing zone on the coastal base.

The 30th Space Wing says residents may see multiple engine burns by the first stage and there may be one or more .

SpaceX has flown boosters back to land after launches from Florida but has yet to do so in California.
