In our first segment, we started with the first caller, Richard Easton who told us about the passing of his Dad, Roger Easton, the father of GPS. Richard has been a guest on the show several times &we were most fortunate to have Roger as a guest as well several years ago. We took this opportunity to honor Roger Easton & talk about the early days of Roger's timing work which formed the backbone of GPS. Richard went through some of the early history with us as he has done on previous shows. I urge you to listen to this call plus go back and listen to Richard's earlier shows, including his first one when Roger was with him. You will hear oral history at its best & from the major scientist/engineer who brought us GPS. After Richard's call, we took our first break. In the second segment, I read a NASA PR announcement about the successful recovery of Dragon bringing back 3,500 lbs. of cargo from the ISS. Congratulations to SpaceX and NASA!. John from Ft. Worth called to talk about the U.S. sanctions on Russia regarding the Crimea/Ukraine, the Atlas 5, the RD-180 engine and various straggles that might unfold for the ISS. John was asking thought provoking questions which neither of us could answer but we do know the situation is largely political rhetoric and posturing right now but could easily change. I asked John if he thought we might fast track the development of HSF and Dragon. As he said, we wait and see. Next, I took a very short break to return with my attempt to respond to the questions about Russia, the ISS, and sanctions asked by Kelly in his email which I read on air. Our next caller was first time caller John from New Jersey who took us through to the end of the program. John's call was an excellent one & I urge you to listen to what he had to say. We talked about the old shuttle policy, the possible use of depots, lunar settlement & using the Moon for training and experience to go further out in space. We also talked about Mars and asteroid mission, then the issue of leadership came up regarding policy & in particular, space. Like so many of us frustrated by our current situation, John was unable to find answers to how to advance policy. I asked him if the militarization of space by another state actor might be a driver for the type of space activities we had been talking about. He did not think so but listen to his answer. One of his favorite comments was to the effect that "we are having Star Trek dreams in a wagon train universe!" Prior to ending our program, I went over our upcoming Space Show schedule.
