NASA is taking steps to potentially roll back the Artemis II rocket and Orion spacecraft to its Vehicle Assembly Building after observing an interrupted flow of helium, the space agency said on Saturday.

NASA aims to launch its next crewed moon mission, Artemis II, as soon as March 6, after a key fueling test showed major progress and only minor issues. Mission managers said the latest wet dress rehearsal — a full practice run that involves loading the Space Launch System rocket with super-cold liquid fuel — met all the main goals.

For the second time this month, NASA has been forced to delay the launch of the spacecraft that will take it back to the moon. The Artemis II mission suffered another setback over the weekend due to an issue with the flow of helium to its SLS rocket's upper stage.
