"The US space agency NASA on Saturday announced that an issue with the flow of helium to the upper stages of its SLS rocket has left engineers with no option but to again postpone the launch of the agency's first manned moon mission in 50 years. NASA Administrator Jared Isaacman said that a bad filter, valve or connector plate could have stalled helium flow,"
""We will begin preparations for rollback, and this will take the March launch window out of consideration," Isaacman said via X. NASA's next opportunity will likely come in April. Artemis moon mission delayed after rocket issue The Artemis 2 mission had been most recently scheduled for launch on March 6. It was intended to send three US and one Canadian astronaut into lunar orbit during a 10-day flight."
NASA identified a helium flow problem to the upper stages of the Space Launch System (SLS) rocket that forced postponement of the first manned moon mission in 50 years and requires rolling the 322-foot rocket back into the Vehicle Assembly Building at Kennedy Space Center. Administrator Jared Isaacman cited a bad filter, valve or connector plate as possible causes and said the March launch window is closed with the next likely opportunity in April. Artemis 2 had been scheduled for March 6 to carry three US and one Canadian astronaut on a 10-day lunar orbit. The issue is not related to prior hydrogen leaks. Artemis has completed one unmanned lunar orbit and has faced repeated technical setbacks, and NASA expects several years to return humans to the lunar surface while China aims for a crewed lunar mission by 2030.
