Best Of: How to Invest in the Coming Space Gold Rush with Tim Marshall

We bring you another favourite from our episodes this year: Merryn's conversation with Tim Marshall, author of The Future of Geography and a former diplomatic and foreign affairs editor at Sky News.He says there could be a "gold rush" in space.
