The first crewed Moon mission in more than 50 years could be launched by Nasa as soon as the first week of February.
The Artemis II mission, which will last about 10 days, could take its astronauts further into space than anyone has been before.
It aims to set the stage for an eventual human landing on the lunar surface for the first time since the Apollo missions of the 1960s and 70s.
Nasa's planned launch window opens on 6 February and runs into the spring. The US space agency wants the rocket to blast off before the end of April.
A date will not be set until final checks on its Space Launch System (SLS) rocket, the Orion capsule - which carries the crew - and ground systems are completed.
