Travel into the cosmos for a four-part series about the ethics of space exploration. Matthew Syed invites you to enter the vast wilderness of the galaxy to explore the moral dilemmas that sit at the heart of space exploration, and why they should matter to you.

When the space race began in the 1960s, the United States and the Soviet Union dominated. Today, multiple commercial entities and many more governments vie for space in the skies above us. Now we may go to other planets not in order to bring back knowledge that will benefit humankind on earth, but potentially to stay and make a new life for the human race… out there. Exploration is turning to colonisation. In this series, Matthew Syed explores the moral underpinning of space exploration beginning with the space race and early attempts to send a message to little green men. He will ask who gets to go to space, how should we behave when we're there, and whether we have the ethical and legal framework to avoid replicating the conflicts we face on earth, up in the skies above us.

Despite all the complexities and necessary moral questions to be wrangled with in this new era, Matthew explores the profound experiences to be had by standing outside our planet. It may offer a unique vantage point to ask questions about who we are, what we owe to each other, where we’re going, and why.
