For the second time in five days, NASA on Saturday halted a countdown in progress and postponed a planned attempt to launch the debut test flight of its giant, next-generation rocket, the first mission of the agency’s moon-to-Mars Artemis program.
The latest attempt to launch the 32-story-tall Space Launch System (SLS) rocket and its Orion capsule was scrubbed after repeated attempts by technicians to correct a leak of super-cooled liquid hydrogen propellant being pumped into the vehicle’s core-stage fuel tanks.
Previously, NASA aimed to make a second attempt to launch its giant next-generation moon rocket on Saturday, Sept. 3, five days after a pair of technical issues foiled an initial try at getting the spacecraft off the ground for the first time.

But prospects for success on Saturday appeared clouded by weather reports predicting just a 40% chance of favourable conditions that day, while the U.S. space agency acknowledged some outstanding technical issues remain to be solved.
At a media briefing a day after Monday’s first countdown ended with the flight scrubbed, NASA officials said Monday’s experience was useful in trouble-shooting some problems and that additional difficulties could be worked through in the midst of a second launch try.
