The rocket launch for the Artemis I mission, the first manned lunar exploration project in 50 years, failed again.

The National Aeronautics and Space Administration (NASA) announced on the 3rd local time that it had stopped the countdown after detecting a leak of liquid hydrogen, fuel, from the lower part of the SLS engine of the 'Space Launch System', the Artemis I mission rocket.

Previously, NASA tried to launch the SLS on the 29th of last month, but suffered the same fuel leak problem, and the first launch was postponed because a temperature sensor defect in the rocket engine and cracks in the insulation were found.
