NASA’s Artemis 1 rocket launch halts September 21 refueling test

NASA is just a few days away from a major refueling test of its massive new vehicle that could make or break the space agency’s chances of launching the Artemis 1 mission to the moon next week.

The refueling test, which NASA will attempt on Wednesday (September 21), will fix two hydrogen leaks on the rocket, called space launch systemas well as a new, slower way to refuel the 32-story engine in the Pad 389A from Kennedy Space Center in Florida. If all goes well, NASA makes its third attempt to launch an Artemis 1 SLS rocket to the moon on September 27 after two false starts in recent weeks.
