NASA will try to launch its "mega moon rocket" again on Saturday, September 3, the space agency said, just days after the first launch attempt was called off because of an engine problem.
The 30-story Space Launch System (SLS), also called the "mega moon rocket," with the six-person Orion capsule on top was set to launch on Monday (Aug. 29).
A core stage RS-25 engine was too hot for launch. This issue and bad weather forced NASA to cancel the launch two minutes into the two-hour window, officials said (Aug. 30).
NASA sees this flight as the first of three important tests of the hardware, software, and ground systems that will be used to send the first humans to Mars and other places in the future.
Monday's launch was scheduled for 8:33 a.m. ET, but problems arose immediately. Lightning threatened to zap the Artemis rocket pad early Monday morning, delaying initial fueling attempts.
After 6 a.m. ET, the team said the liquid hydrogen fuel was only cooling three of the rocket's four engines before ignition.
NASA will try to fix this issue for Saturday's launch by performing engine chilling half an hour earlier, a trick that worked in a test last year.
NASA is putting a lot of faith in the success of the Artemis 1 mission, which has been criticised for its skyrocketing price tag.
NASA wants to launch Artemis before Sept-10, peak hurricane season. No named hurricanes have formed this year, but increasing storm activity in the Atlantic basin suggests the calm could be ending.
