Artemis II hit with new setback as helium flow halts launch prep
NASA has rolled back the Artemis II rocket to the Vehicle Assembly Building after a helium-flow problem in the upper stage of the Space Launch System, delaying a March liftoff. Engineers are investigating the cause while officials consider potential April launch windows, with further testing likely. When/if it launches, Artemis II will carry four astronauts on a 10-day lunar flyby, marking the first deep-space mission since Apollo ended in 1972.
