NASA’s all-new Space Launch System moon rocket and Orion spacecraft will return to the launchpad for final testing in “early June,” the space agency announced at the weekend.
A wet dress rehearsal involves filling the rocket with fuel and performing a countdown as if for an actual launch. But during April’s effort, various technical issues emerged that prompted engineers to return the rocket to the Kennedy Space Center’s Vehicle Assembly Building until they could resolve the issues.
The space agency added that the team also updated software to address issues encountered during the fueling stage in those earlier rehearsal efforts.
They should use that alien technology from the 40s instead of jet fuel.
