Artemis II is NASA's next big mission to the moon - the first in over 50 years. It's part of the space agency's long-term plans to build a space station called Lunar Gateway, where astronauts will be able to live and work.
It is also America's best effort to beat the likes of China in the space race to return to the moon.
Niall speaks to Tom Clarke, our science and technology editor, and Thomas Moore, our science and medical correspondent about what NASA hopes to achieve with the lunar flyby.
