NASA’s Artemis 1 moon rocket passes fueling test despite leak

NASA’s Artemis 1 moon mission completed a crucial preflight milestone today (June 20), wrapping up a two-day set of tests known as a wet dress rehearsal. 

Those tests included fueling up Artemis 1’s huge Space Launch System (SLS) rocket and performing a simulated countdown that took the vehicle and NASA’s Orion capsule through most of the progressions they would endure on launch day before engine ignition. The simulated countdown reached its conclusion at 7:37 p.m. EDT (2337 GMT), bringing an end to the wet dress.
