NASA delays moon mission to fix rocket, rules out March launch

NASA is preparing to remove its massive moon rocket from its launchpad to fix a technical issue, delaying the agency’s much-anticipated mission to send a crew of four around the moon.

On Saturday, NASA announced that it planned to roll back the rocket, the Boeing-built Space Launch System, to its hangar at Kennedy Space Center in Florida to fix a problem found in the upper portion of the vehicle. NASA engineers found an interruption in the flow of helium — which is needed for launch — in the rocket.
