The Falcon 9 rocket was due to launch with 60 Starlink satellites at Cape Canaveral Air Force Station in Florida tonight.
SpaceX wrote on Twitter: “Standing down today due to excess upper level winds. Teams are working toward tomorrow’s backup launch window, which opens at 10.30pm EDT (2.00am BST).”
The company tweeted the day before weather was “favourable” for the launch.
They said: “Weather is 80 percent favourable for tomorrow’s Falcon 9 launch of Starlink.”
Meteorologist Mike Favetta said they were 120mph east winds at 41,000 feet.
He wrote on Twitter: “Reusable rocket tries to launch, but 120mph east wind at 41,000 feet says nope. Better weather tomorrow.”
SpaceX fans have taken to social media to express their hope for a launch tomorrow night.
