Astronaut Stuart Roosa was a real-life action hero - Sue Nelson and Richard Hollingham speak to his daughter, Rosemary, about the Apollo 14 Command Module Pilot’s life, mission and the seeds he carried with him to the Moon. Plus Sue visits a real Moon Tree down the road from Space Boffins HQ - the only one in the UK. We also chat to Her Excellency Sarah Bint Yousif Al Amiri, Chair of the UAE Space Agency about their mission to Mars, astronauts and international partnerships. And we tackle the big questions - how big is space? and what’s your favourite satellite?
