Nasa has said it hopes to send astronauts on a trip around the Moon as soon as February to prepare for landing there as early as 2027.
The US space agency had previously committed to launching no later than the end of April but said it aims to bring the mission forward.
It's been 50 years since any country has flown a crewed lunar mission. Nasa will send four astronauts there and back in ten days to test systems.
The Artemis II mission is the second launch of the Artemis programme, whose aim is to land astronauts and eventually establish a long-term presence on the lunar surface.
