We welcomed Robert Sackheim to the program to discuss NASA, commercial space, the current state of rocket propulsion and advancements in the field.  During our first segment of this 1 hour 47 minute discussion, Mr. Sackheim talked about his background and experience at TRW, NASA MSFC, and his current consulting.  I asked him several questions about the current state of rocket propulsion. Bob had much to say about this, focusing on chemical rocket propulsion, satellite propulsion, electric propulsion, and the need for nuclear propulsion.  He talked about booster rockets, various rocket stages and their propulsion, rocket engines, and even SRBs.  Several questions came in asking him if we had the current technology for HSF to Mars or even the Inspiration Mars flyby mission talked about so much in the recent press.  Listeners wanted to know if our current levels of propulsion were up to the task.  After a rather thorough propulsion discussions, Bob turned to commercial space, lowering total space mission costs, regulatory policy, and commercial spaceports.  He also talked about budget issues and raised the question a few times as to why ten NASA centers were needed given their often overlapping, competitive, and duplicate work.

In our second segment, commercial space took the lead with a discussion on public/private partnerships & the belief that Americans can do anything if we set our mind to it, including space travel.  Of course here the problem as we know lies in leadership and today it appears that leadership in space & other areas is sparse at best.   Bob then focused on geo satellites and the increasing development and capabilities applicable to cubesats.  HSF came up for discussion as did the robotic missions. You might be surprised by what our guest had to say about HSF.  Other issues in this segment included the lunar space elevator, the congressional and NASA track record in canceling ongoing projects & taking lessons from history, SSP, & ways to reform & move NASA forward.  Bob spoke about evolving toward the old NACA model.  I asked about the impact of space advocacy from his perspective given his leadership experience and past positions in leading organizations and projects.  We also asked him about space tourism and hybrid rocket engines. He had much to say about hybrids, don’t miss the discussion.  Bob talked about the Falcon rockets, testing including static fire tests, and SRBs as related to the Constellation project and safety.  Toward the end, our guest was asked about NewSpace, fuel depots, & cryo transfer.  For closing comments, he talked about commercial space being the way to go & the path to our space future.

We welcomes Bob Zimmerman back for a two hour wide ranging discussion on space news, company updates, sequestration, policy, and more.  Be sure to check out his blog, http://behindtheblack.com.   Bob started out talking about the e-book release of his book, “Genesis, The Story of Apollo 8.”  He then talked about the upcoming Falcon 9 launches, their importance and significance.  Bob mentioned ILS and the Proton rocket which is having its problems causing insurance rates to rise. He said the Russians will absorb all insurance cost increases to keep Proton at a price advantage point.  This opened the door to a discussion about SpaceX and price competiveness in the launch industry.  Bob switched gears to the suborbitals and said we should be seeing Virgin powered tests soon.  He also talked about Stratolaunch per a recent Parabolic Arc article.  Bob was talking reusability and the RLV so I asked him if he was aware of economic analysis and data that was not supportive of an RLV short of a substantial increase in launch demand. Bob had much to say about this with his opinion. The RLV economic issue continued to be discussed in both segments of our program. Tim called in about it as well.  We talked about Sen. Rubio and his budget amendment suggesting NASA divest itself of unused assets & use the saved money for commercial space.  Bob then brought up sequestration and the announcement that NASA will be shutting down all public outreach but they will keep their PR arm going for their projects and missions.  We also mentioned Sarah Brightman and both her ISS and Virgin space tourism efforts.  Near the close of this segment, Inspiration Mars was discussed and as you will hear, Bob is skeptical, citing human factors & other reasons for his opinion.  Larry asked about North Korean rockets and threats to the U.S. west coast.  Bob said he took them seriously though their rocket was not yet ready for prime time. Bob also threw in Iranian rockets and threats and said he was more concerned about advances by Iran than N. Korea at this time.

In segment two, we talked about both the science side of NASA and the HSF side.  I’m sure you will find the comparison and mission summaries of interest.  John called in from Atlanta to raise yet again the question of reusability.  He thought it would be enhanced with the use of orbiting fuel depots. Bob was skeptical.  Don’t miss this discussion.  I asked both Bob and John about Inspiration Mars, Jim emailed in a comment about Falcon 1 relative to comments being made by Bob, and we talked about the upcoming Orbital Sciences Antares launch.  We got into the subject of risk taking and Bob and I talked about mining risks as well as caving risks.  As Bob is an accomplished caver, he had much to say about both mining and caving.  Near the end, we got a call about various spaceports in different states and spaceport commercial success so far.  Bob concluded saying that we are in an unstable world which could absolutely adversely impact all aspects of space and commercial space development and progress.
