The launch of Nasa’s most powerful ever rocket has been delayed due to a tropical storm that could become a hurricane.
Artemis I Moon rocket was expected to launch from the Kennedy Space Center, in Florida, on Tuesday.
But the US state faces a hurricane threat as tropical storm Ian has strengthened and could approach Florida early next week as a major hurricane.
The lunch of the rocket had already been postponed twice.
The Space Launch System (SLS) vehicle is designed to send astronauts and their equipment back to the Moon after an absence of 50 years.
A decision on whether to return the rocket to its assembly site is due to be taken by the Artemis I team on Sunday.
This would be “to allow for additional data gathering and analysis”, NASA said.
