More than 50 years since the last Apollo mission, Nasa is preparing to send astronauts back to the Moon.

Artemis II will take its crew farther from Earth than any human has travelled in decades - a crucial step towards landing on the lunar surface once again. At the same time, China has been quietly advancing its own plans for a crewed Moon landing.
