NASA has completed what may have been the final ground test of its next-generation Space Launch System rocket before its much-anticipated maiden mission to the moon.
The entire procedure took about 12 hours and marked the first time for the SLS rocket’s propellant tanks to be fully loaded with fuel. The test ended with a mock countdown, a critical period of any rocket launch when many activities take place in rapid succession. The agency said that during propellant loading operations early on Monday, engineers spotted a hydrogen leak in a component that attaches an umbilical from the tail service mast on the mobile launcher to the SLS rocket’s core stage. April’s test also featured a hydrogen leak though it’s not yet clear if the two issues are linked.
