Liftoff of NASA’s Artemis I is scheduled for later today, as long as teams can overcome refueling issues. As of now, the launch is scheduled for 2:17 p.m. (ET) and you can watch live below.
The Artemis program has been one of the most anticipated in recent history. Artemis I is an unmanned mission that will lay the groundwork for future launches that will include returning humans to the surface of the Moon, and possibly Mars. It was originally scheduled to take place on August 29, 2022, but was delayed due to a critical engine issue.
On Monday, an engine purge problem occurred, prompting NASA to scrap its first Artemis launch attempt. When asked what an engine purge was, NASA replied: “An engine purge is part of our regular pre-launch operations to prepare the engines. Teams prefer not to put in super cold fuel in hot engines, so we first run liquid nitrogen through them to cool them.” Now, it looks like the team ran into a different problem ahead of today’s scheduled launch.
A liquid hydrogen leak is now the culprit hampering Artemis I launch attempts. There appears to be a recurring leak in a cavity between the ground side and flight side plates of a quick disconnect in the engine section. At this time, the teams are discussing possible troubleshooting attempts. As of this writing, the team is again attempting to warm up the quick disconnect to try and reset the seal.
The launch window is still scheduled to open at 2:17 p.m. as NASA continues to try to fix the quick disconnect issue. You can watch live above via NASA’s official YouTube channel.
