Have you ever wondered who owns Mars? That's just one of the topics of the Making New Worlds podcast series by Erika Nesvold. Erika is a Ph.D. astrophysicist and a lifelong space travel enthusiast. Prof. Margaret Newell was a panelist on episodes 3 and 4 of the series.
(Podcast 3 description from MakingNewWorlds.com:) Once we’ve taken that giant leap for mankind and have set foot on a new world, we have to ask: Who actually owns the land we’re standing on? If you’re planning on making your fortune in space by mining or farming or building new habitats, how do you get the rights to work that territory? Do we want to use the same capitalist land-ownership system a lot of us use here on Earth, or is it time for a new way of handling property? Is it even legally possible to own land in space?
