Jan. 30 (UPI) -- Frigid temperatures have delayed NASA's preparations for its wet dress rehearsal for the Artemis II launch, the space agency announced Friday. NASA was expected to begin the tanking operation Saturday night in preparation for a possible Feb. 6 or Feb. 7 launch date, but those "are no longer viable opportunities," a release said . The agency now expects to set Monday as the tanking day with an earliest possible launch set for Feb. 8 at the Kennedy Space Center in Cape Canaveral,
