In this episode, Dara and Isy are joined by the astronaut Helen Sharman to learn about how humans learned to survive in space - with some diverting conversations about glitter, cat statues, hibernation, and shell suits.

What? Seriously?? is a new podcast which combines comedy with quirky history, hosted by Dara Ó Briain and Isy Suttie, who will unravel an extraordinary real-life tale each week with the help of a celebrity guest

Dara and Isy unearth stories that are definitely true, but also kind of unbelievable at the same time - the sort of stories that make you go ‘What? Seriously??’ when you hear them, but you resolve to tell them in the pub the first chance you get. The twist is that Dara and Isy have absolutely no idea how these strange-but-true tales will unfold and we’ll all be trying to figure it out together – or Dara and Isy will just go off on funny flights of fancy that are tangentially related to the story. They will be drip-fed the nuggets of narrative by a special guest expert who might just know something about the subject.

Across the series they will be joined by I’m A Celeb winner Georgia Toffolo, the Aussie comedian Rhys Nicholson, the broadcaster Stuart Maconie, Master Chef star Louisa Ellis, Miles from The Traitors, the comedian Richard Herring, the astronaut Helen Sharman, and Slow Horses star Chris Chung.

‘What? Seriously??’ with Dara Ó Briain and Isy Suttie and special guest Helen Sharman.
