With the toilet venting problem endangering the spacecraft Integrity’s Michelin rating, BBC Science Editor Rebecca Morelle drops by to update us on the unmentionables. The team answer more listeners questions; what do we mean by zero-g, and will there ever be permanent relay satellites around the moon to prevent the forthcoming communications blackout?

Tim Peake, Kristin Fisher and Maggie Aderin discuss the impact on mission architecture that the plurality of commercial launch providers are having in this new space race.

The Artemis II crew have also been sending down more of their photographs of Earth and the growing Moon from Integrity, the Orion spacecraft. With more and more talk on the mission becoming camera related, photographic restoration specialist and bestseller “Apollo Remastered” author Andy Saunders joins Tim, Maggie and Kristin to discuss what we can learn from these pictures and how photography has changed since Nasa’s early space programs.
