We welcomed Dr. Henry Hertzfeld back to the show for a fascinating 90 minute discussion regarding commercial space, human spaceflight (HSF), recently announced HSF Mars missions, increasing the launch rate, and more. During our initial segment, Dr. Hertzfeld addressed my question about lowering launch prices to increase the launch rate. Dr. Hertzfeld did a classic economic study on this subject several years ago and I asked him if today’s current market and commercial space progress had altered his earlier conclusions. He said no. Later, I asked if space solar power (SSP) could drive launch rates down. The short answer was no but don’t miss what he had to say about SSP economics, launches, and debris issues. Jerry emailed in a question about SpaceX being a commercial company given its receipt of government money. Henry had much to say about what makes a company commercial or not and if it is even an important issue. Another listener wanted to know about the deep space commercial ventures announced in 2012 and in 2013. The listener wanted to know if these were really commercial ventures, if regulations could stop them, and what would happen re the ventures needing property rights or the equivalent. One of the things our guest reiterated several times during our discussion was the need for stability and predictability for the commercial industry. Questions came in about benefit sharing and he mentioned the likelihood that some sort of international system would develop on these issues. I asked what constituted an acceptable ROI and the example of controlled ROIs as in the utility industry came up. Doug wanted to know about rocket reusability and its impact on launch costs. We also talked about both Mars One and the new Inspiration Mars mission. As part of this discussion, astronaut rescue and the rescue treaty were discussed. In the second segment, Doug called to discuss property rights for a NEO as opposed to the Moon, wondering if the Moon might be more valuable. Doug & Henry talked about our having returned lunar rockets as a model for commercially returning lunar products but Henry suggested there might be a difference in returning something for science as compared to commercial exploitation. Later, we addressed human spaceflight and its challenges. The Chinese space program was brought up as was the risk of a space war. Dr. Hertzfeld was asked about putting 10,000 people on Mars, space migration, species survival, space settlement, and the need to explore as possible drivers for HSF. My final question pertained to our evolving to a business friendly environment in space. Simply put, we are not there yet.

Guest: Dr. Scott Pace. Topics: Space policy, COTS, HSF safety, commercial space & more. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Dr. Scott Pace back to the program for a comprehensive discussion on a variety of topics impacting space policy, commercial space, and both our civil and entrepreneurial space communities. We started our first segment with a summary of the AIAA-IAF Global Space Exploration Conference held last week inWashington,DC. We talked about the international make-up of the conference, the focus on budget issues, commercial space, and some of the different issues of concern to Europe, Asia, and theU.S. We also talked about the impact on the Europeans of theU.S. terminating certain space program partnerships as the Europeans do four year planning and budgeting unlike theU.S. which is year to year. Our first caller was Michael Listner about the European Code of Conduct for Outer Space. This was a comprehensive and important discussion on a subject that we are sure to hear more about over time. TheU.S. may even sign on to it so I strongly suggest everyone pay attention to this issue & this discussion. We mentioned recent public comments about the Law of the Sea Treaty and looked at the potential impact of the treaty on space development should theU.S. modify or adopt a version of the treaty. Toward the end of the first segment, Jerry sent in a note asking about comments made to the Washington Post by our guest on the number of test flights that might be needed for the Falcon 9, plus the response from NASA Watch. Dr. Pace talked about HSF flight safety, rocket testing programs, and how today differs from the early days of our human spaceflight history. Risk averseness was part of our conversation.
In our second segment, we talked about the rational for human spaceflight. Dr. Pace offered a geopolitical rational for HSF rather than just a capability driven program and rational. Here we talked about Asian countries emerging as space powers and participants along with what happens when we aim for Beyond LEO (BLEO) and the need to engage the new players. You will hear Dr. Pace advocate a return to the Moon several times during our program as that is a way to engage new players, plus we need to learn certain skills all over again before going BLEO. We switched topics & talked about increasing the NASA budget & treating NASA as an investment, not an expense. Dr. Pace brought our focus to what do we get for what we spend. Don’t miss this discussion. We talked about commercial crew, down selecting as an option, and competition. Dr. Pace put these issues into the form of a cost-benefit analysis project to be examined based on the goals of the desired or stated policy. Again, don’t miss his analysis of these issues. We also talked about the FAR and the SAA, insight, oversight, accountability, and higher costs coming from the FAR. Property rights & land claims were brought up along with space settlement issues. Listener Jim inquired about using the Dragon for BLEO missions. Scott had much to say about this potential. Toward the end, we talked about theU.S. budget deficit & what we spend on NASA, then I read a letter from two 5th grade students opposing space development & I asked Dr. Pace to provide us with his reply. We concluded our discussion with Dr. Pace honing in on the need for leadership here and abroad, along with the need for a robust economy.
Please post your questions/comments on The Space Show blog. If you want to email Dr. Pace, you can send your note to me & I will forward it to him.

Guest: Todd Halvorson. Topics: Upcoming Falcon 9 & Dragon launch, Floridaspace policy, NASA & more. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Todd Halvorson, senior aerospace reporter for FLORIDA TODAY & USA TODAY to the show. During our first segment, we mostly discussed the upcoming Falcon 9 launch scheduled for Saturday early morning, May 19 2012. Note that Florida Today is having special coverage and programming starting at 3:30 AM EDT. To tune in, visit www.floridatoday.com. Todd detailed the coverage at the start of our next segment. Also in the initial segment, we talked about Congress, commercial crew, down selecting, the Space Act Agreement, and theU.S. human spaceflight program, such that it is a program. Also mentioned was the SLS program along with Orion, then I asked about the space coast economy per the recent 60 Minutes segment last month. Todd had much to say about the 60 Minutes Segment, especially the visuals they used. Don’t miss it. Listener Jane asked about the differences in policy ideas between NewSpace and the old space crowd, especially the very well known astronauts who are most vocal in support of a more traditional NASA program. Todd had much to say about this and we talked about the future NASA as either a space tax service or an organization that explores BLEO. Another topic of interest dealt with the Chinese space program and going to the Moon. Our listener asked if Chinese space plans might start a space competition with theU.S. We then talked about the FY 13 budget for NASA and the possibility of doubling NASA’s budget as proposed by Dr. Tyson. As the segment ended, we discussed Planetary Resources and sought Todd’s perspective on what has been made public so far.
In the second segment, Todd went into detail about the Florida Today broadcast for the Falcon 9 launch. Terry called in to ask about the ISS GPS issue and then we asked Todd to describe what happens when Dragon gets to the vicinity of the ISS. The process goes on through Wednesday morning. Another listener asked for Todd’s analysis of the space program over his 25 year history of reporting space news. Our next topic honed in so the suborbital companies in Mojave, space tourism, and suborbital research. This discussion included spaceports inFlorida,California,Virginia,New Mexico and elsewhere. As our program was nearing its end, we talked about Constellation, Ares 1, SRBs, Dr. Mike Griffin, SLS, and civility. In his closing comments, Todd again said we should have a space program that explores and is not a space taxi service.

Guest: Robert (Bob) Zimmerman. Topics: Space X static test, Congress & commercial crew, Planetary Resources & space property rights. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Bob Zimmerman back to the program to discuss today’s Falcon 9 static test, Congress & commercial crew, and the Planetary Resources announcements of last week. Visit Bob’s website for more information, http://behindtheblack.com. During the first segment, Bob talked about congress and its proposed treatment of commercial crew including down selecting the companies, reducing funding, and moving to the FAR instead of remaining with the Space Act Agreement. Bob got lots of questions about markets in space and why commercial companies need government money in the first place. In this segment, we also talked about the Falcon 9 static test today and its relevance for congress. Bob targeted SLS for discussion. As you will hear, there was not much support for SLS among those of us listening to today’s program.
In the second segment, we talked about the Planetary Resources venture announced last week. Part of our focus was on the 9″ space telescope, its likely uses and resolution. We talked about it for asteroid finding and Earth imaging – with serious reservations. Bob suggested that the real business for the company was in selling the space telescopes to customers wanting that product or service as the mining was still a decade or so out into the future. In talking about the telescope, we discussed pointing, stability, resolution, being placed on the Moon, and less than ideal light coming from the asteroids. In talking about space telescopes, we discussed Hubble and the JWST. In other space news updates, Bob talked about Orbital moving Antares to the pad for its testing and there is an article on his blog about it being seriously over budget: www.flightglobal.com/news/articles/orbital-sciences-development-costs-increase-371291. Another topic we discussed was the Chinese political system and its turmoil, also its economy and how this might impact their space program. Bob had much to say about this as well as India and its space program which he said might prove to be the dark horse in space development. Toward the end of this 2 hour 8 minute program, Michael Listner called in to talk about legal issues for Planetary Resources in their resource extraction stage of development, plus property rights, the Outer Space Treaty and even the impact of the Moon Treaty. Bob and Michael had a spirited debate about these issues, including the potential influence of the Moon Treaty and international customary law which Bob completely dismissed. Michael has an excellent article on the subject at www.spacesafetymagazine.com/2012/04/26/commercial-space-leap-earth-orbit-legal-implications/.

Guest: Mark Bray. Topics: Space industry standards, policy, politics, & space workforce attitudes. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back Mark Bray for what was a most interesting and wide ranging 2.5 hour discussion divided into two segments. We started off with Mark talking about the need for industrial standards both in the public and the private space sectors. A good portion of this initial hour long segment was about design and quality standards. Mark explained by example why there were needed and what he was talking about. His Florida concrete company example made it very clear why the standards he was talking were and are needed. Mark made some very good points, we had good listener participation both on the phone and with emails. I promise that you will think differently about standards and the space industry after you listen to this segment.
We started the second segment talking about SLS as Mark works on the SLS project. I asked him if the workforce was aware of the opposition to SLS and what they thought about it. This opened the door for Mark to talk about space workforce issues, their fears and concerns, and what is happening to the workforce given the current political, election year politics, economic condition, and the fact that they are not working on a space mission with goals and a destination. Listen to what Mark had to say on all these issues. While you may not like what you hear, keep in mind that Mark in engaged as part of this workforce and speaks from experience. In response to a listener question, Mark had much to say about Huntsville, Marshall, and Alabama space politics. Part of this discussion focused on NewSpace and why Alabama has been slow in seeing opportunities with NewSpace rather than trying to block elements of it. Jon called in from Jersey City and had a good discussion with Mark about these & other issues and then he introduced space enthusiasts to the mix in terms of what this community wants and expects for policy. This brought me to one of my rants on policy and my playing the Devil’s Advocate with both Jon and Mark. Eventually, the three of us talked about how we seem to be forced into selecting one way or the other for space development and dismissing that which is not the “preferred” one way. We also talked about congressional responsibility for how they handle taxpayer money while enthusiasts have no such responsibilities. Next, we arrived at why we all seem to be fighting over shrinking resources and getting “our” piece of a smaller and smaller pie. We talked about the need to grow the economy, to grow the space sector, and to grow the economic pie, not shrink it. We agreed that while there may be many solution paths to the problems facing the U.S., space provides a clear path and solution set that seems hard to match by other possible directions and choices if economic expansion and wealth creation are to be the goals of our national policy. Also mentioned was how NASA is not considered one of the key science and technology agencies, Near the end, Mark got an interesting question about long duration storage requirements for SRBs. Don’t miss Mark’s closing comments. Finally, the paper he mentioned during this interview is on his website at http://braynstorms.com/wp-content/uploads/2011/12/Achieving-Innovation-and-Affordability.pdf.

You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomes Mark Sirangelo of Sierra Nevada Corp Space Systems to the program to discuss Dream Chaser, hybrid rocket motors, human spaceflight, space policy, budgets and more. You can learn more about Dream Chaser at http://sncspace.com/space_exploration.php. For those of you interested in learning more on the previous NASA HL-20 concept vehicle, visit www.nasa.gov/centers/langley/news/factsheets/HL-20.html. We started our discussion by asking Mr. Sirangelo for a brief history and overview of Dream Chaser. He talked about the lifting body design and the capabilities of a lifting body, including costs and reusability. In response to questions he did say it was meant for LEO though later in the program he discussed the potential to scale Dream Chaser up if markets warranted it. He was also asked to compare the Dream Chaser style of vehicle to a capsule. Mark was asked about the choice of rocket, the Atlas V. While he explained that choice, he also said Dream Chaser was rocket agnostic. Don’t miss his comments on the rocket question. A listener asked him to clarify the current status with the SAA, the FAR, and a possible CCDEV 3 round of NASA support. Mark said there would be a round three with a call for awards in February with winners announced later in the summer. He talked about the companies going to the next level, the Critical Design Review (CDR) and what this means for NASA as well as the companies. Mark talked about the switch back to the SAA but said at some point down the road, the FAR will likely be used, probably in the acquisition stage. Again, you do not want to miss what he had to say on this important issue. Yves from Canada asked about the launch abort system for Dream Chaser and its ability to land in places and the ocean instead of a designated runway. We talked about test flights, the number of needed flights, and the view that testing is not based on the number of flights but on successfully completing the essential and needed testing/flight protocols. In our second segment, Trent called from Australia and wanted to know more about the full history and struggles for Dream Chaser up to now. This time around Mark provided us with a more comprehensive vehicle history. We also talked quite a bit about the hybrid rocket motor so you will for sure want to hear this segment. Mark was asked if the Dream Chaser hybrid was the same being used for the Virgin SS2 and he said essentially yes other than for size. He was asked some more questions about his work on SS2 for Virgin but deferred those questions to Virgin . Our guest received a few questions about the GAP, buying rides on the Soyuz, recent Soyuz issues, and speeding up the development of Dream Chaser. Harry wanted to know about using Dream Chaser for various types of orbital space tourism, and much was said about certifying Dream Chaser as safe for human spaceflight. Near the end, Robert wanted to know if Dream Chaser might be used for Point to Point travel. John from Jersey City called to ask about multiple markets for Dream Chaser. As our discussion was drawing to a close, our guest was asked about hypergolic fuels and reaction control systems and again about the thermal protection system.

Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. The Space Show/OGLF is now engaged in its annual fundraising drive. Please see & act upon our appeal at http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign. We welcomed Tom Olson back to the show for his annual yearly summary of space events. We had much to cover in this 105 minute program. Tom started out reminding us that 2011 was the 50th anniversary of human spaceflight. He told us about the banner year for Yuri’s Night parties around the globe celebrating this important milestone and specifically about the even he attended in New Your City. Next, he pointed out the recent National Press Club talk given by Elon Musk on going to Mars and building the rockets to take us there, plus his recent New Scientist interview which you can read in full on the Mars Society website. Tom commented that the sky was actually falling in 2011 with two large junk satellites coming back to Earth. We also talked about the return of Phobos Grunt to earth probably in early to mid-January 2012. One of the big events we discussed for 2011 was the retirement of the shuttle. This led us to discussing the recent Chinese space rendezvous and the fact that China is now the number two launching country behind Russia having overtaken the U.S. this year. Planetary missions were part of our year in review with Vesta and Dawn, the Kepler Space Telescope, MSL with Curiosity. New Horizons continued its journey to Pluto and Explorer 1 continued beyond our solar system. Tom talked about SLS and the ORION MPC Vehicle, plus the James Webb Space Telescope and its cost issues in the context of its impact on the NASA budget. Soyuz rocket problems along with all the Russian rocket failures this year were fair game for our discussion. I asked Tom what he thought of the idea of SLS as a place holder for skill sets and technology until our space program improves. Don’t miss his answer. He brought up Virgin Galactic’s drop tests this year, especially the last one where trouble showed up. Making news for 2011 were NASA and space industry workforce layoffs and the successful Falcon 9 and Dragon launch. At the end of the first segment, Bigelow Aerospace was in our spotlight. In segment two, Tom led off with XCOR news, Terry called wondering about CCDEV3 and Tom suggested program winners! Don’t miss his prediction. He also was asked to predict the cancellation year for SLS. Don’t miss this prediction as well. We talked about the upcoming New Space Business Plan Competition for 2012, the prizes which are the largest ever, and the timing. If this interests you, make sure to stay tuned for more information. Later in the segment we began a summary of our discussion and 2011. Tom was asked about the space elevator and the Lunar Space Elevator. We wrapped up our discussion talking about growth in the space conferences even in the tough economic year of 2011. Post your comments and questions on The Space Show blog URL above.
