Tech guru Elon Musk’s SpaceX rocket lit up the sky leaving Californians puzzled.
The rocket was launched at about 5.30pm (9pm GMT) in Los Angeles on Friday.
It successfully propelled 10 satellites into orbit an hour later.
The rocket first appeared as a red light which looked more like an unusual coloured star.
As it gathered height Californians were in awe as they saw a streak of light streaming across the clear sky at sunset.
