During the first segment of our two hour seven minute program, we took several calls starting with John in Florida who wanted to talk about early Mars colonization, one way Mars trips and similar topics. He wondered about buried Martian ruins deep under the ground and I drew an analogy to archaeological digs here on Earth in finding towns and early civilizations buried on top of one another far below the surface of the Earth. John from Ft. Worth called in to talk about the Al Worden interview in which Al did not think there was any reason for returning to the Moon. You can read the Worden interview at www.dw.de/apollo-15-command-module-pilot-alfred-m-worden-nasa-took-a-ste.... I also asked John about the release of thousands of UFO documents, www.usatoday.com/story/tech/2015/01/19/air-force-ufo-files/21985651. John and I then returned to discuss more about the Worden interview, his comments on the shuttle, the ISS, Saturn V and more. In the second segment, Michael Listner called to update us on the settlement of the SpaceX Air Force litigation. Michael summarized the mediation and the settlement details for us. Dr. Doug from S. California called to talk about a variety of topics including radiation. He referred to an Al Globus article regarding his view on shielding requirements. You can read Al's article here: http://space.alglobus.net/papers/RadiationPaper2014.pdf. Doug also talked about a permanent base on the Moon and his Mars Return Option. Dwayne was the next caller and he spoke of John Logsdon's upcoming book on Apollo and the Nixon space policy. He talked about all the budget cuts and slashes back then and how they negatively impacted the program. Dwayne also talked about the nuclear thermal rocket and the fact that it can't go active until it out of Earth orbit. Adrian sent in an email about radiation debris putting satellites at risk. Here is the older NY Times article he sent me: www.nytimes.com/1995/02/26/world/radioactive-debris-in-space-threatens-s.... Tim called to debunk the Mars crew living in a tuna can analogy and instead wanted to compare it to submarines. He got some pushback on his submarine analogy. Earlier, Jon from NJ had sent in a note about the SpaceX satellite plans & what this may mean for SpaceX. Please post your comments/questions on TSS blog.
