NASA will make a second attempt to launch its powerful new Moon rocket on Saturday, after scrubbing a test flight earlier in the week, an official has said.
Blast-off had been planned for Monday morning but was cancelled because a test to get one of the rocket's four RS-25 engines to the proper temperature range for launch was not successful.
Mike Sarafin, mission manager of Artemis 1 at NASA, announced the date for the new launch attempt - a key step in the US programme to return astronauts to the Moon - during a media briefing yesterday,
The goal of Artemis 1, named after the twin sister of Apollo, is to test the 98-metre Space Launch System rocket and Orion crew capsule that sits on top.
The mission is uncrewed - mannequins equipped with sensors are standing in for astronauts and will record acceleration, vibration and radiation levels.
Tens of thousands of people - including US Vice President Kamala Harris - had gathered to watch the launch, which comes 50 years after Apollo 17 astronauts last set foot on the Moon.
