NASA has been forced to postpone an historic rocket launch - one that has been 50 years in the making.
The uncrewed Artemis One mission was supposed to have blasted off overnight from Cape Canaveral in Florida, in the first step towards sending humans back to the moon.
The launch was cancelled due to several technical issues, mostly with the rocket's engines.
Space.com editor Tariq Malik spoke to Mani Dunlop from Florida.
