NASA has confirmed the Artemis II mission will launch at 6:24 p.m. Wednesday from Kennedy Space Center, with a two-hour window. The four astronauts currently at the space center are preparing for the first lunar flyby since 1970. The launch was delayed from February due to leaks during a wet dress rehearsal, but NASA says all systems are now go. "We understand how important this trip around the moon will be," said one astronaut. "Honoring how humanity shares the same moon in the sky is really important to us." The mission could set a record for the farthest distance from Earth ever reached by humans. The current record, set in 1970, is 248,000 miles. Weather remains the primary concern, with an 80% chance of favorable conditions at launch time. Clear skies are expected along the Space Coast, offering prime viewing opportunities. Local residents and visitors are gathering at Cocoa Beach, Titusville, and the Kennedy Space Center Visitor Complex to watch the historic event. The countdown will begin around 3 p.m. Wednesday. The mission aims to test systems for future lunar landings and establish a sustainable presence on the moon. No issues with the spacecraft or rocket have been reported, according to NASA officials. The Artemis II crew includes two veteran astronauts and two rookies, who will spend about 10 days in space. The launch window closes at 8:24 p.m. Wednesday if conditions are not optimal. Local authorities are advising spectators to arrive early for parking and safety. The mission is part of NASA's broader Artemis program, which seeks to return humans to the moon by 2025.
