NASA delays Artemis II crewed moon flyby to at least April due to helium system issues.
NASA is rolling its moon rocket back to the Vehicle Assembly Building at Kennedy Space Center for additional repairs, delaying the Artemis II mission until at least April.
The rollback follows a helium system malfunction that disrupted fuel pressurization and engine purging, complicating recent fixes to hydrogen fuel leaks.
Engineers are investigating the issue, with the April launch window still possible but dependent on repair progress.
The mission, which will send four astronauts—three Americans and one Canadian—on a crewed flyby of the moon, marks the first such trip since 1972.
The crew remains on standby in Houston, and launch opportunities are limited each month due to orbital mechanics.
