Summary:
- NASA's Artemis II mission, the first crewed flight of the Orion spacecraft to the Moon, has been delayed due to a rare Arctic outbreak affecting the launch site in Florida.
- The simulated launch window for Artemis II will open tonight, allowing NASA to practice the countdown and launch procedures without an actual liftoff.
- The Artemis II mission is a crucial step towards NASA's goal of returning astronauts to the lunar surface, with the first uncrewed Artemis I mission successfully completed in November 2022.
