NASA postponed the launch of Artemis I, the mega rocket that aims to go beyond the moon and return to Earth. It's the first launch in NASA's Artemis program, which hopes to return humans to the moon for the first time since 1972.
Here's everything you need to know about the scrubbed launch.
NASA highlighted these issues that factored in the decision to scrub:
- There was an issue with engine bleed in engine #3, according to Artemis mission manager Mike Sarafin. Super cold liquid hydrogen is cycled through the engine to get it ready it for launch. The other three engines were performing as expected.
- The team knew that engine bleed issue was a risk heading into this launch campaign, and it would be the first time demonstrating that successfully, Sarafin said Monday.
- There was also an issue with the vent valve in at the inner tank, he added.
- Besides these issues, the weather conditions were also not favorable during the launch window — there was precipitation in the beginning and lightning later on, Sarafin explained.
What happens next: The launch team will "reconvene tomorrow" to discuss options, Sarafin told reporters Monday.
The next possible launch window is Friday: NASA had already determined more than one launch date for Artemis I before the launch was postponed Monday. The next availability is this Friday, Sept. 2, which is still "in play," according to Sarafin, but engineers still need to troubleshoot the issue to determine if NASA can use that launch window.
The Sept. 2 launch window will open at 12:48 p.m. ET and last two hours.
