Caravans in Space

The plans to set up human colonies in space and spaceships that will take us to the stars. Richard Hollingham travels to the Tennessee Valley Interstellar Workshop in Chattanooga, Tennessee to meet scientists, engineers, doctors and anthropologists who are working on it.These are not dreamers - although they all have an ambitious dream - but well qualified experts. Several work at Nasa, others have day jobs at universities and research institutes.Richard hears of proposals to build giant space stations and worldships - vessels packed with the best of humanity. These caravans in space might be lifeboats to escape an approaching asteroid or perhaps the first step to colonising the galaxy.With contributions from Technical Adviser to Nasa's Advanced Concepts Office Les Johnson, Director of the Space Engineering Centre at the University of Arizona John Lewis, architect Rachel Armstrong and anthropologist Cameron Smith.This programme first aired in November 2016.

We Shall Fly - Part One

Why African nations are so keen to journey into the future as a space-going continent. Space scientist Maggie Aderin-Pocock visits Nigeria, the birthplace of her father, to explore the passionate desire among some to fly against the continent’s impoverished stereotype and join the space race. And, what of the financial commitment required to achieve these dreams in countries where it is sometimes a struggle to keep the lights on?"Quite a few false starts have been made in Africa," wrote the Ugandan philosopher and writer Taban Lo-Liyong, "...but most of us know the direction we are going – straight into the 21st Century. And to arrive there we are not going to go the way our grandparents would have gone – on foot and by canoe. We shall fly, we shall go by missiles, we shall go with the white man, we shall go with the yellow man. And we shall go by all means."We follow this poetic, aspirational spirit through the continent’s history, from speaking to the South African hoping to be the first black African in space, to a surprising and touching example of amateur space exploration in 1960s Zambia. What do these ambitions mean, and who believes in them?This programme was first broadcast in October 2016.
