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. Please post your comments/questions on The Space Show blog. You can reach Mr. Sackheim through me at drspace@thespaceshow.com.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed back Dr. Bruce Cordell to discuss the ten major space trends for 2013 and the Maslow Window forecast for a coming period of ebullience, economic boom, and large space projects. For more information, visit his website, www.21stcenturywaves.com. His article titled "10 Space Trends for 2013 - Featuring the Approach of the New International Space Age can be found at http://21stcenturywaves.com/2013/02/13/state-of-the-wave-10-space-trends-for-2013-featuring-the-approach-of-the-new-international-space-age. During the first half of our two hour discussion, Dr. Cordell took us through the history of his development of fractal Maslow Window forecasts, plus the historical data used to predict a Maslow Window. After his introduction, we then talked about Mars and the excitement surrounding Mars with the Curiosity rover and the newly announced Inspiration Mars HSF mission Mars flyby per Dennis Tito. Dr. Cordell spent considerable time connecting the dots for us to the importance of the Inspiration Mars mission & the coming predicted boom and period of ebullience. Michael Listener called in to suggest the possibility of the government not providing a launch license for the Inspiration Mars launch. This sparked an intense discussion regarding the likelihood of the government blocking such a mission. In our second segment, Dr. Cordell talked about the space relationship to the war threats made North Korea and Iran. Here, he connected the dots to the U.S. B2 Korean flyover and the Iranian and N. Korea threats to precursors that show up before the boom and period of ebullience. He cited the Cuban Missile Crisis as an example prior to Apollo. Again citing the precursors, he suggested that the "bumpy road" most always led to the boom period. Several email listener questions came in regarding the U.S. & global economic condition & how it impacted his forecast. Here, he referenced panics before each boom. Bruce suggested we would be entering the period of ebullience around 2014 or 2015 but he also cited some reasons why the period could possibly be delayed, thus appearing much later. But he definitely cited periods of financial panic as precursors to the boom periods. He also talked about geopolitical events & their influence, including the role of conflicts. Near the end of our program, he talked about the importance of the 2014 elections & our then had more to say about the Tito Mars flyby mission. Please post your comments/questions on The Space Show blog. You can email Dr. Cordell through his website or drspace@thespacesow.com.

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.

Michael brings to the table his experience with NASA and the Applied Physics Lab at John Hopkins as he was the spacecraft systems engineer for the NASA Messenger mission. During the first segment of our 95 minute program, Michael talked about the Lunar Lion project. We discussed launch contracts and vehicles, secondary payloads, landing sites, hoppers as opposed to rovers, and what happens to the hardware at the end of the mission. We talked about the Penn State students working on the project and listeners and I asked questions about his experiences on Messenger being applied to a GLXP project. The listeners seemed to think this was a step or two down but listen to how Michael explained lessons learned and applications to the Lunar Lion project. We also talked about funding for their project and that if they win, the money goes to Penn State to endow further space related research and students. We also had a treat in the first segment in that Michael's 10 year old son was with him. We invited him to the program and it appears we may have a future space guru in the making! In the second segment, we talked about space education and general audience space enthusiasm and awareness given Michael's public talks. He had some interesting comments and experiences to share with us. We also talked about potential regulations adversely impacting their mission, sample returns, lunar activities and such. Charles called to talk about up and downstream communications and the use of lasers. Spacecraft quality control was another issue along with the development of commercial tools for a much broader application than the Penn State GLXP entry. He also mentioned efficiency in spacecraft design and management but used the term, "a frugal approach." He explained the difference between frugal and efficiency in terms of spacecraft design & management. As our program ended, we talked about thermal protection, radiation hardening, film and space subjects and topics. Our final topic was oversight and 3rd party eyes on their project for review & quality control. Post your comments/questions on The Space Show blog. You can email our guest through the Lunar Lion website or derspace@thespaceshow.com.

John Strickland, Monday, 3-19-13 (59.25MB; download) -- Guest: John Strickland. Topics: NSS, ISDC, space settlement, SSP, launcher reusability & more. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed back John Strickland for this two hour discussion on a wide range of topics of interest to the NewSpace, commercial space, and space settlement audiences. John started out by talking about the upcoming NSS ISDC Conference in San Diego from May 23-27. For more information visit the NSS website, www.nss.org and click on the ISDC link. Some tracks are still open for submitting abstracts so if this interests you, click on the appropriate link at the ISDC site. During this part of our discussion, John talked about the NSS Roadmap and the planned coverage of it at ISDC 2013. John was then asked about the deep space commercial and Mars ventures announced in 2012 and so far this year. He said they were helpful to the overall space settlement agenda and explained how in his discussion comments. He added that the Mars missions and Golden Spike were "laudable" but suggested we may not be ready by the time the projects give for doing the venture. He later said he would have spent the money differently. Don't his miss all his comments on these new commercial and HSF missions to Mars. Our conversation then focused on the problems of sequestration and then John talked about heavy lift and SLS. Our next discussion topic was Space Solar Power (SSP). Here, John took us through a detailed analysis of why terrestrial solar and wind is not the best way to go, then he went through some of the characteristics of SSP and why it is the preferred way to acquire much of our energy. This is a detailed and at times marginally complex discussion but one you will want to hear. In the end, he suggested we delay until we have the bigger launchers such as Falcon Heavy or bigger to make the launch component more economical. His analysis included total energy needs for a city, Texas, the U.S., globally, etc. It is a very instructive discussion. Near the end, he said we should not put all our eggs in one energy source basket. Listen to his solid explanation for this suggestion. In our second segment, John talked about launcher reusability and more regarding SSP. He introduced us to space logistics, commercial docking with cargo to the ISS, & the need for reusable deliveries, thus the RLV. From here, he talked about fuel depots, mostly at Earth-Moon L1 and L2. He explained the boil off problem, the cryogenic transfer problem, and the need for good insulation plus a cryo cooler. Other issues in this segment addressed a lunar base, plausible time lines for accomplishing much of what our guest talked about, the Chinese space program and the complicated US-China relationship. Near the end, a listener asked about a possible Texas spaceport per suggestions of SpaceX. Tim called just before the end of the show to talk fuel depots, types of propellant for the depots and then he mentioned the VAPAK process (see http://ralph.open-aerospace.org/PDF/2009.04.14%20-%20HCG%20White%20Paper%20-%20VaPak%20Overview.pdf.)
