- Artemis 1 rocket launch scrubbed again.
- Technical issues prevented the launch.
- Engineers discovered a liquid hydrogen leak.
NASA, for a second time, scrubbed the highly anticipated launch of Artemis 1, an unmanned rocket launch to the moon. Saturday marked the second launch attempt window.
The launch was scrubbed due to a liquid hydrogen leak in a line leading to the launch system. Engineers troubleshot the issue and applied two separate potential fixes, trying one of the fixes twice. However, they were not able to adequately address the issues with enough remaining time to complete the launch.
The core stage liquid hydrogen tank was filled with about 57,000 gallons of the roughly -423 °F element. That’s only about 11 percent of the tank’s capacity.
The decision to scrub the launch was made around 11:20 a.m. ET. The launch was originally scheduled for sometime in a two-hour window beginning at 2:17 p.m. ET.
The first launch attempt was on Monday. Monday’s launch was scrubbed due to an engine temperature issue among other problems.
The next launch window opens on Monday at 5:12 p.m. ET but it remains undetermined whether NASA will move forward with a launch attempt on that day due to the recent technical issues. Still, if weather conditions remain favorable as forecast, and there are no technical failures of Artemis 1 systems, the awaited launch could finally happen.
“The team is now going into the cut-off procedure after being unable to resolve a hydrogen leak. The vehicle is safe. NASA Test Director Jeff Spaulding is now putting the team into a configuration to drain propellants from the tank,” said Derrol Nail from NASA Communications.
