Guest: Rick Tumlinson. Topics: U.S. Space Policy, Obama space policy, Constellation, NASA, space development. Rick Tumlinson was the guest for this two hour program divided into three segments. However, given that our topic of discussion for almost the entire show was the proposed new direction for NASA and the Administration's space policy, there was no need to break this description into segments. Rick began the discussion with some ground work regarding opening space to the human settlement and the frontier beyond Earth.
