Home-base preparations ahead of Artemis II's crew splash down off California's coast on Saturday afternoon. 

The four astronauts are on the return trip to Earth after their historic lunar flyby.  

NASA landing and recovery director, Liliana Villarreal says a ship's heading towards the capsule landing zone.  

The crew will then be helicoptered to dry land, for post-flight medical checks. 

US Correspondent Richard Arnold told Mike Hosking the ship will pierce the Earth’s atmosphere at a speed of just over 40,000 kilometres an hour – seven times the speed of sound.
