NASA's Artemis-2 mission, aiming to return humans to the Moon for the first time in over 50 years, has been delayed from its planned March launch. A second dress rehearsal for fueling the SLS rocket encountered issues with helium refueling of the upper stage, a problem also seen during Artemis-1. The rocket will be returned to the Vehicle Assembly Building for investigation, with a potential April launch window opening as early as April 1st and closing on April 30th. NASA Administrator Bill Nelson acknowledged the disappointment but drew parallels to the Apollo program's setbacks. The ten-day mission will orbit the Moon with a crew of Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen, preceding Artemis-3's planned lunar surface landing in 2028.
