One to One

Tech journalist Jack Dearlove grew up with Microsoft Messenger. Back in the early 2000s, it was vital for teen communication. Jack is nostalgic about it, and he’s not alone. Here he speaks to software developer Jonathan Kay who has tried to keep MSN Messenger alive even after Microsoft tried to kill it off. Producer: Jolyon Jenkins

In 2011, tech journalist Jack Dearlove was at university and won a competition to go to the Kennedy Space Center to "live tweet" the last American Space Shuttle. As a self-confessed space nerd, it was one of the most exciting - and emotional - days of his life. But what was it like for the astronauts on board? Here he talks to Doug Hurley, one of the four on board. Now in his fifties, Doug is still planning one last mission into space, with Elon Musk's new generation of space craft. If successful, it will allow American astronauts once again to go into space from American soil. Producer: Jolyon Jenkins

In the last of three programmes exploring our experiences of travel and why we do it, Lynne Truss joins Will Parsons, co-founder of the British Pilgrimage Trust on a short pilgrimage along the Old Way in East Sussex. They begin under the ancient Yew tree in Mary and St Peter’s Church in Wilmington and walk via the Long Man and Saint Peter of Vincula in Folkington to St Andrews’ Church in Jevington. The journey offers Lynne a chance to discover what a pilgrimage is and how it differs from a walk. Aided by her pilgrim’s staff it proves to be a journey of unexpected encounters and experiences for Lynne - unnerving, calming, reflective and enjoyable. Producer Sarah Blunt

Lynne Truss talks to Jillian Moody about her experiences of travelling across the world in a campervan with her husband and three young daughters. The family bought a second-hand campervan prior to the trip which had no shower and no toilet and after a terrible first night, reality took its toll as they realised their itinerary would have to change. They were faced with many challenges en route but after 38,000 miles, there's no doubt it was a life-changing experience for Jillian. Producer Sarah Bunt.

The Economist's Soumaya Keynes continues her quest to find out why the study of economics is so dominated by men. Does that affect the kind of economics we get, and why does that matter? In her second programme, Soumaya meets Professor Stephen Machin, Director of the Centre for Economic Performance at the London School of Economics, who thinks it's a problem some in his profession are failing to recognize.
