NASA has announced a delay in the launch of its Artemis II mission, initially scheduled for February, now pushed to March 2026 due to a hydrogen fuel leak detected during a critical wet dress rehearsal. According to Business Recorder, NASA Administrator Jared Isaacman stated, 'With the conclusion of the wet dress rehearsal today, we are moving off the February launch window and targeting March for the earliest possible launch of Artemis II.' The test, which involved filling the rocket's tanks with over 2.6 million liters of super-cold hydrogen and oxygen, was halted when a leak was detected, requiring the team to pause and adjust the propellant flow. This issue is reminiscent of similar problems that delayed the Space Launch System rocket's debut three years ago, as reported by the South China Morning Post.
