Start the Week

On Start the Week, as the first Briton heads into space for two decades, Andrew Marr explores the future of space travel. Kevin Fong is an expert in space medicine and in this year's Royal Institution Christmas Lectures looks at how to survive in outer space. The Astronomer Royal Martin Rees questions whether human space travel is worth the money or the risk, while the astrophysicist Carole Haswell searches distant galaxies for habitable exoplanets. Stephen Baxter is a writer of hard science fiction who, as a member of the British Interplanetary Society, investigates star ship design and extra-terrestrial liberty. Producer: Katy Hickman.

On Start the Week Tom Sutcliffe picks through the remains of vanished buildings with the writer James Crawford. In his book, Fallen Glory, Crawford looks at the life and death of some of the world's most iconic structures. The conductor Semyon Bychkov explores why some music fades, and the enduring appeal of Tchaikovsky's Eugene Onegin. Julia Sallabank studies endangered languages and whether it's possible to revive indigenous languages on the verge of extinction. And it is origins which feature on Peter Randall-Page's latest sculpture: a naturally eroded glacial boulder carved with stories of creation myths from cuneiform to text speak. Producer: Katy Hickman.

On Start the Week Andrew Marr looks at the fortunes of Saudi Arabia. The academic Madawi Al-Rasheed challenges pre-conceived ideas about divine politics and uncovers the religious leaders, intellectuals and activists who are looking at modernising the country. William Patey is the former UK ambassador in the region and argues that although the House of Saud is resilient, strains are starting to appear. The American economist Deirdre McCloskey sees fault lines elsewhere in the country's failure to promote and encourage innovation; she believes that although Saudi Arabia has capital accumulation and oil, without creativity and ideas it will not flourish. The historian Ian Morris takes the long view as he studies 20,000 years of international relations and argues that each age and region gets the great powers it needs, and what that means for Saudi Arabia. Producer: Katy Hickman.

On Start the Week Andrew Marr explores goodness and its uneasy relationship with pleasure. The historian Robin Lane Fox looks to the work of Augustine and what is thought to be the first autobiography detailing the sinful excitement of youth before his anguished and hesitant conversion to Christianity. The philosopher Clare Carlisle explores Augustine's views on the link between desire and habit, while the psychoanalyst Adam Phillips asks why pleasure is more highly prized when it's perceived to be forbidden and guilty. Larissa MacFarquhar looks at the lives of those who have dedicated themselves to others and asks why do-gooders provoke deep suspicion in Western culture. Producer: Katy Hickman.

On Start the Week Mary Ann Sieghart takes a satirical look at the world with the novelist Jonathan Coe. His latest book is a state-of-the-nation satire which takes aim at politics, social media and inequality. It's the battle between ideals and pragmatism in the cynical world of the political elite of the 1920s which takes centre stage in the play Waste, famously banned when it was first written, now revived and directed by Roger Michell. The Times' political cartoonist, Peter Brookes, celebrates the power of the visual image to lampoon the country's leaders and the playwright Mia Chung explores whether satire can do justice to the questions raised by a regime like North Korea and talks about her latest play about two sisters fleeing the country. Producer: Katy Hickman.

Andrew Marr was in Paris on Friday to record a special edition of Start the Week about France. Hours later the Paris attacks happened. This programme is not about these attacks or Islamic State or the French role in the war in Syria, but it is a conversation about the political, cultural and religious fault lines in France from the 19th century to today. As BBC Radio 4 plans to broadcast a retelling of Emile Zola's 20 novel cycle, Les Rougon-Macquart, the journalist Anne-Elisabeth Moutet explores whether Zola is a 19th century gateway into understanding modern France. The novelist Agnès Desarthe has set her latest novel at the beginning of the 20th century and mixes the intimate with the great events of French history. The French Resistance is one of France's heroic myths and is central to the country's identity, but the historian Robert Gildea says the reality is far more complex. And contemporary France in all its complexity is represented in Karim Miské's thriller set among the radical Islamic preachers, Christian fundamentalists and corrupt police officers in one of the poorest suburbs of Paris. Producer: Katy Hickman.

Anne McElvoy presents a special edition of Start the Week at the Free Thinking Festival at Sage, Gateshead, exploring injustice, myth and the role of the poet 'to name the unnameable, to point at frauds, to take sides'. The American poet Claudia Rankine exposes the ever-present racial tensions in contemporary society, while the Syrian poet Amir Darwish, having arrived in the UK hanging underneath a lorry on a cross-channel ferry, writes of love, loss, exile and demonisation. The historian Catherine Fletcher looks at the stories told about Alessandro de'Medici, the 16th century duke of Florence who was believed to be mixed-race, and what those stories tell us about attitudes to race, while the philosopher Jules Holroyd tackles the thorny issue of implicit and unconscious bias. Producer: Katy Hickman.

On Start the Week Tom Sutcliffe discusses the importance of uncertainty and failure. The former head of the European Research Council Helga Nowotny argues research is fed by uncertainty and that any form of scientific inquiry may produce results that are ambiguous. She criticises policy makers for focusing on easy short-term solutions, but the former conservative MP and Minister for Universities and Science, David Willetts, understands the difficulty for governments in dealing with uncertainty. In his role at the think tank Resolution Foundation he's attempting to use analytical research to improve policy on living standards. Matthew Syed examines how a positive attitude to failure can lead to success in areas as diverse as sport, business, politics and healthcare. The failure of governments to come to an agreement on climate change will be discussed next month at a UN conference in Paris and Oliver Morton looks at whether the radical, yet uncertain, strategies of geo-engineering are the answer. Producer: Katy Hickman.

On Start the Week Andrew Marr talks to the playwright Ben Power whose latest work interweaves three of DH Lawrence's dramas to evoke a lost world of manual labour and working class pride. The sociologist Mike Savage proposes a new way to think about class in Britain which not only looks at economic and social issues, but cultural preferences. Meanwhile the American writer Siri Hustvedt questions the cultural misogyny at play in the world of art, and Peter Davies celebrates the artists inspired by the northern industrial landscape. Producer: Katy Hickman.

On Start the Week the classicist Mary Beard tells Tom Sutcliffe that Ancient Rome matters: its debates about citizenship, security and the rights of the individual still influence our own debates on civil liberty. The Magna Carta is the starting point for the playwright Timberlake Wertenbaker's latest play which draws parallels between the King's abuse of power in 1215 and the global business elite today. The film director Stephen Frears tells the story of the meteoric rise and fall of one of the most celebrated and controversial sportsmen in recent history, Lance Armstrong, and of the journalist who was vilified when he tried to expose him. Lurid headlines take centre stage in the play Clarion, directed by Mehmet Ergen, which takes a satirical look at nationalism and the state of the British media. Producer: Katy Hickman.
