Tech guru Elon Musk’s SpaceX rocket lit up the sky scaring the bejesus out of Californians.
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 colored star. As it gathered height Californians were in awestruck and somewhat shaken as they saw a streak of light streaming across the clear sky at sunset.
Several celebrities joined fellow social media users in questioning what the mysterious light was. Skateboarding legend Tony Hawk, who was 120 miles south of LA in San Diego, asked: “What is this in the sky?”
Some users speculated that it was a UFO and aliens were coming to visit.
Musk, the multi-billionaire founder and lead designer at SpaceX, posted a video of the rocket in the sky and joked: “Nuclear alien UFO from North Korea.”
The Los Angeles Fire Department had to issue an alert explaining that the “mysterious light in the sky” was the rocket launch.
The Falcon 9 rocket was launched from the Vandenberg Air Force Base for communications firm Iridium, which was part of one of the largest tech upgrades in history, SpaceX said.
