We welcomed Paul Turner to the show to discuss his new book "The Space Trade" and his concept for developing orbital real estate for profit. Visit his website for more information, www.thespacetrade.com. In the first segment of our 1 hour 55 minute show, Paul introduced us to The Space Trade idea. He first described what the mature space trade industry would look like, then he talked about how to develop a space trade. He suggested the space trade would likely start with asteroid mining and he referenced Planetary Resources multiple times during our discussion. He also mentioned the need for an orbital transfer vehicle and a spin ship which he described later in the discussion. He talked about mining water and bring it back to LEO. He recalled he had seen a suggested price for water at $50 million/ton in LEO which he said was on the Planetary Resources website at one time. Later in the segment, this price was disputed by several listeners. Listeners asked questions about the potential profitability of the space trade early stage since Paul thought it might not be profitable at the start. Another early industry suggested by Paul was the servicing and refueling of satellites. Joe then asked if a proof of concept could be applied to capturing small asteroids near Earth and bringing them back to Earth targeting their re-entry to land in Australia somewhere. Paul said it was possible and it was important to have a proof of concept for people to see. John from Ft. Worth called to inquire about space manufacturing. Paul had much to say about this part of his concept. In the second segment, a listener asked about property rights and the national as well as international legal regime to make possible the space trade. JP emailed in about manned vs. unmanned asteroid mining. Benny asked Paul to describe a spin ship. Later Robert inquired if lunar development might be the starting point for the space trade industry rather than asteroid mining. Listeners asked Paul many other questions including one about why establishing a space trade was important. Paul referred us to chapter 12.1 of his book but he did mention a few of the reasons. Later, he talked about the Carrington Event. I asked him what our TRL was for getting the space trade going and he said we could start today. Don't miss what he had to say about this. In closing comments, he advocated doing something rather than just talking about it. Pooley then called to talk about DIY space plus they discussed the old Conestoga project and JP emailed in on that as well. Please post your comments/questions on TSS blog.
