Artemis I launch updates: Saturday launch scrubbed after reoccurring liquid hydrogen leak
It comes after the launch was scrubbed Monday due to an engine problem.
NASA kicked off Monday its plan to send an unmanned space capsule into the moon’s orbit, marking the initial launch in an ambitious plan to establish a long term presence on the moon for scientific discovery and economic development.
The space capsule, called Artemis I, will travel for roughly 40 days -- reaching as close as 60 miles from the moon, and then 40,000 miles above the moon when orbiting over its dark side -- before landing in the Pacific Ocean off the coast of San Diego.
After the launch was scrubbed, the next attempt will occur Sept. 3.

NASA scrubs Artemis I launch
NASA announced a few minutes after Artemis I was initially scheduled to lift off that the launch has been scrubbed.
Engineers said the problem came from a liquid hydrogen line that was not chilled enough inside one of the rocket’s four core-stage engines, which needs to occur before they can be ignited.
The next attempt will occur on Sept. 2.
Artemis launch delayed due to storms, rocket troubleshooting
Artemis I will likely not be launching at 8:33 a.m. ET as originally planned after NASA ran into several delays in its preparation to send it into space.
The process of tanking, which includes filling the rocket's core stage with liquid oxygen and liquid hydrogen, was delayed due to some passing storms and lightning in the area, NASA said.
Moreover, a leak was discovered in the hydrogen fuel line, which NASA quickly resolved. The leak concentration was “at an acceptable level,” NASA said.
Engineers also discovered a potential crack in the inner stage flange, which connects two of the rocket's cylinders.
The countdown clock is currently paused at T-40 and the launch can go as late as 10:33 a.m. ET If that window passes, the next attempt at launch will be Sept. 2
NASA moves Artemis launch date to Saturday
NASA officials announced Tuesday that they've moved the launch of Artemis I to Saturday.
Mike Sarafin, Artemis mission manager, told reporters during a media briefing that the mission management team met earlier in the day and agreed on the new date.
"We agreed on what was called option one, which was to operationally change the loading procedure and start our engine chill down earlier," he said.
One of the reasons for the scrub on Monday was because engine three did not cool down enough to the point needed for ignition, he explained yesterday.
"We also agreed to do some work at the pad to address the leak that we saw and we also agreed to move our launch date to Saturday, September the 3rd," Sarafin added. "We are going to reconvene the mission management team on Thursday, September the 1st, to review our flight rationale and our overall readiness."
