Nasa’s Artemis II crew are now closer to the Moon than they are to Earth. Hosts astronaut Tim Peake and space scientist Maggie Aderin are joined by space journalist Kristin Fisher, who gives us the latest on the crew’s momentous journey, as the Integrity spacecraft begins its gentle deceleration before the point when the moon’s gravity starts pulling it more strongly than the earth’s.

And the team answer a question from listener Mark. Has Artemis II had to dodge space junk on its way to the Moon, and if so, how is it detected and avoided?

And planetary scientist Professor Sara Russell joins Tim, Maggie and Kristin to explain how the Moon got its water, what resources are drawing private companies to the Moon, and what a future lunar base would have to look like to withstand the Moon’s conditions.

Season 4 theme music by Hans Zimmer and Christian Lundberg and produced by Russell Emanuel, for Bleeding Fingers Music.

13 Minutes Presents Artemis Two is a BBC Audio Science production for the BBC World Service.
