SpaceX’s launch of the world’s biggest and most powerful rocket system has been postponed after it experienced a glitch minutes before take-off.
The launch, from the southern tip of Texas, near the Mexican border, had been due to take place at any point in a two-hour launch window after 8am local time.
But, the countdown was stopped with 40 seconds to go.
Then, after the launch window elapsed, the firm revealed a valve on the Starship rocket was found to be frozen.
SpaceX chief Elon Musk said another launch would take place “in a few days” and the company had “learned a lot” from today’s test.
The California-based space company announced that it was calling off another flight attempt for at least 48 hours.
The Federal Aviation Administration (FAA) had issued SpaceX with a license to put its most powerful rocket system through its paces, saying it met all safety and environmental requirements.
