NASA delays Artemis II moon mission to Feb. 8, 2026, due to cold weather halting fuel test.

NASA has delayed the Artemis II crewed moon mission to no earlier than February 8, 2026, due to near-freezing temperatures at Kennedy Space Center, which prompted the cancellation of a key fueling test. A revised dress rehearsal is planned for Monday, weather permitting, with only a narrow three-day window in February to launch four astronauts on a lunar flyby before the mission shifts into March. NASA is using heaters and system adjustments to protect the Space Launch System rocket and Orion spacecraft. The crew remains in quarantine in Houston, with their travel to Florida uncertain. The mission marks the first crewed lunar flyby since 1972 and is constrained by strict launch windows and weather conditions.
