NASA delays Artemis II crewed lunar mission to March 2026 over rocket issues.

NASA has delayed the Artemis II mission, the first crewed flight of the SLS and Orion spacecraft, to March 2026 due to issues during a wet dress rehearsal test. Problems included anomalies in the rocket’s liquid hydrogen system, such as pressure fluctuations and a leak, prompting engineers to investigate and repair. The delay ensures safety and thorough resolution of technical challenges. The mission will send four astronauts on a lunar flyby to test systems ahead of future moon landings.
