Why is the US going back round the Moon with Artemis II? A space policy expert explains

Final preparations are underway for NASA’s Artemis II mission, the first crewed mission around the Moon for more than 50 years. Four astronauts, three men and one woman, will spend 10 days aboard the Orion spacecraft, going further into space than any other humans as they orbit the Moon and return to Earth.

Issues caused by a fuel leak while testing the Space Launch System rocket used for the mission meant launch windows in February and March were missed. Now NASA is targeting early April for launch.
