UK and Ireland's best-loved comedian Dara O Briain takes you on a journey from the safety of your comfiest chair to the furthest reaches of space (and beyond!)

So you want to go into space? WHY?! (No, really - it's sort of a terrible idea. We humans are perfectly designed for life on Earth. We can walk around, breathe, drink water, eat vegetables, read books, not get poisoned or crushed to death when we go outside - it's lovely right where we are.)

Not convinced? GOOD! People have been dreaming about space travel for centuries - there's something amazing about the idea of leaving our planet behind and setting out to explore the Universe - there's so much we still don't know.
