In the latest setback to return astronauts to the moon, NASA delayed the highly anticipated flight yet again after a new problem cropped up with the rocket Saturday.
April is now the earliest that the four Artemis II astronauts could fly to the moon.
NASA revealed the latest problem just one day after targeting March 6 for Artemis II, humanity’s first flight to the moon in more than half a century. Overnight, the flow of helium to the rocket’s upper stage was interrupted, officials said. Solid helium flow is essential for purging the engines and pressurizing the fuel tanks.
This helium issue has nothing to do with the hydrogen fuel leaks that marred a countdown dress rehearsal of the Space Launch System rocket earlier this month and forced a repeat test.
NASA Administrator Jared Isaacman said a bad filter, valve or connection plate could be to blame for the stalled helium flow. Regardless of the cause, he said, the only way to access the area and fix the problem is to return the 322-foot (98-meter) rocket to its hangar for repairs.
