Nasa is set to send humans deeper into space than ever before, but there's one piece of technology that still has some kinks - the Orion space capsule's toilet.
Since launching from Earth on Wednesday, the four astronauts aboard the Artemis II mission's Orion capsule have had some intermittent issues with their toilet.
At one point on Saturday, the toilet was unable to dump its waste overboard, possibly due to a frozen vent line, Nasa said. The astronauts have instead used an alternative system which involves collapsible plastic containers that collect their urine.
Despite some toilet troubles, Artemis II is successfully into day five of the historic 10-day mission around the Moon.
The four crew members - Nasa's Reid Wiseman, Victor Glover and Christina Koch and Canadian Space Agency astronaut Jeremy Hansen - are in a small cabin about the size of a camper van, just 5m (15ft) wide and 3m (9ft) high.
