Launch attempt of Artemis 1 scrubbed after leak detected; next try comes into play October

LATEST:

NASA Administrator Bill Nelson, Associate Administrator for Exploration Systems Development Jim Free and Artemis Mission Manager Mike Sarafin spoke Saturday around 4 p.m., addressing the scrub of Saturday’s Artemis 1 launch.

“We usually do not launch until we think it’s right,” Nelson said. “Our teams have labored over that and that [scrubbing] may be the conclusion they found…Safety may be the the surface of the list.”

Free said the launch won’t come Monday or Tuesday, but will have to be later, likely late September or October. Late September is not as likely due to conflicts with SpaceX Crew 5.

“We don’t get into these tests lightly,” Free said. “We were confident getting into today, but we’re not likely to launch until we’re ready.”

Sarafin stated the large hydrogen leak occurred when crews went from the “slow fill” to the “quick fill.”

He said teams tried 3 x to solve the leak, but were unsuccessful. He added that how big is the leak created a flammability risk and that hydrogen is volatile.

Sarafin said engineers discussed multiple options but none could have allowed for the launch to occur prior to the end of the launch period on Sept. 6.

Officials confirmed the rocket should be rolled back again to VAB as the batteries have to be changed.

Nelson stated that will not presently pose any risk to the timeline for future Artemis missions: Artemis II is still slated for 2024 and Artemis III continues to be slated for 2025.

“The expense of two scrubs will be a lot less than failing,” Nelson said.
