After three previous aborted attempts, NASA successfully fueled its new massive deep-space rocket, the Space Launch System, for the first time on Monday \u2014 completing a critical milestone ahead of the vehicle\u2019s first flight. However, there was a shadow over the achievement. The fueling was part of an elaborate dress rehearsal that ended 20 seconds earlier than NASA had planned, and it\u2019s unclear if the agency got all the data and practice it needed to proceed with the rocket\u2019s debut launch.<\/p>\n

The Space Launch System, or SLS, is a key piece of NASA\u2019s flagship Artemis program \u2014 an elaborate effort to send the first woman and the first person of color to the surface of the Moon. But first, SLS needs to actually fly, and before that can happen, NASA wanted to go through all of the intricate steps<\/a> that lead up to an actual launch \u2014 except for the part where the rocket takes off. <\/p>\n

With the SLS standing upright on its launchpad in Kennedy Space Center in Florida, NASA engineers and flight controllers filled the vehicle with its ultra-cold propellants on Monday, just as they would on a launch day. With all the SLS tanks full, the flight team counted down to a simulated liftoff time, with the plan to stop the countdown at roughly T-minus 9 seconds. Instead, the team stopped the countdown short at T-minus 29 seconds due to a hydrogen leak. NASA says it was able to complete most of its objectives for the test, primarily loading the vehicle with propellant \u2014 but that there are still a handful they weren\u2019t able to get to with the premature cutoff.<\/p>\n
