Why are humans going back to the Moon, and is there really life on Mars?

Space is back! No longer the reserve of a couple of superpowers, an increasing number of countries are getting involved, and the private sector is playing a greater role than ever. On this episode, NASA Chief Economist Alexander MacDonald talks about plans to return to the Moon, and Pascale Ehrenfreund, president of the Committee on Space Research, explains why we are looking for life on Mars and beyond, and what that might look like.
