The director of the lunar exploration program, Artemis 1, said NASA hopes to be able to resolve technical issues in time to restart the launch.
According to the original plan, on 29/8, the Orion will begin its first mission into space, without carrying a crew.
This is an important trip as part of NASA’s Artemis 1 mission to return humans to the Moon, which has been long delayed.
This multibillion-dollar project is seen as a stepping stone for future missions to Mars.
Orion will orbit the moon before returning to Earth 42 days later.
