Lucy, Peter and Kellie discuss how private industry and wealth has kickstarted the space race in the 21st Century and identify who the players are.

Seven tourists have booked a visit to the International Space Station, at huge cost. Lucy discovers who will take us to space, where we can go and when might prices fall.

When will humans eventually reach Mars? Lucy hears predictions about how people will get there, what they will experience and whether travellers will ever come back.

The Solar System is abundant geologically. How and when could people mine asteroids and planets; who is attempting this and what are the potential benefits for us here on earth?

Who owns space? What are the laws governing space mining and the complications of zero gravity crime and punishment? Do aliens have rights under earth law?

Over 70 countries now have a space programme. Will this, together with commercialisation, lead to greater collaboration or potential conflict?

As more of us become space travellers, how will humans adapt both physically and mentally in order to leave our planet for months or years on end?

Lucy, Kellie and Peter speculate on the sci-fi futures that might become reality as more humans travel into space. Could a new human species emerge on Mars?
