NASA delays astronauts’ lunar trip until March after hydrogen leaks mar fueling test

NASA postponed its first crewed lunar mission in over 50 years until at least March after hydrogen fuel leaks plagued a critical dress rehearsal test of the Space Launch System rocket. The same hydrogen leak issues that delayed the rocket's uncrewed debut three years ago resurfaced during Monday's fueling operation, forcing controllers to halt the countdown at five minutes. The delay will allow engineers to conduct additional testing before sending four astronauts on the historic lunar fly-around mission.
