We welcomed Dr. Eligar Sadeh back to the show to discuss his recent Astropolitics published article, “Report: Public Private Partnerships and the Development of Space Launch Systems in the United States.”  You can find this report on The Space Show blog for this particular program. During the first segment of our 92 minute program, Dr. Sadeh introduced us to the topic and the Report subjects which you can read on TSS blog.  He addressed the traditional aerospace contracting model, the problem with cost overruns which hurt the traditional model and some of the issues with fixed price contracts, especially with technology and commercial opportunities.  We talked about risk reward and he cited SpaceX and Orbital Sciences as examples of the success of the private public partnership type of arrangement.  In addition, Eligar suggested that such partnerships were supportive of developing programs such as space transportation services.  Other topics in the first segment included SLS, National Security Space, big science programs, planetary missions, and others that still use the traditional model.  Our guest introduced us to the Better Buying Power approach which he referenced several times during the show.  Tim called from Huntsville to talk about risk, profits, and cubesats.  Eligar then went into some detail about the competitive launch environment, specifically for national security payloads and how that is now changing and opening up.  Jake emailed us to inquire if Congress was fully on board with these new public private partnerships.  Jennifer wanted to know how international participation might change the public private partnership relationship.  Next, I asked Eligar to explain the Acquisition Death Spiral which was in Fig. 4 of his Report paper.

In the second segment, John from Ft. Worth was our first caller & he wanted to address the risk in a fixed price contract.  John and Eligar had an interesting discussion on controlling costs and risks so don’t miss it.  Later, I asked Eligar to explain the New Entrants Certification Guide (NECG) which was issued in 2011.  This document provides the guidelines for the competitive launch environment for national security and other launch competitors.  Our next caller, Doug, wanted to talk about public private partnerships beyond LEO, specifically the Moon.  Eligar talked with Doug about leveraging assets for the private sector, citing the ISS and a few of the commercial users as examples.  Both Doug and Eligar had a very interesting and comprehensive discussion on this topic which considered cislunar transportation, a lunar hab, possible commercial incentives to drive commercial involvement, and more.  Policy and leadership were part of this discussion as was the fact that there currently is no lunar hab, Lunar Cots, or cislunar transportation policy nor is one being considered.  After the discussion with Eligar ended, we used the balance of our time to discuss the likelihood of a fast moving lunar based Chinese space program influencing the US to fast track developing a lunar hab and cislunar transportation.  Prior to our discussion ending, I asked Eligar how listeners could get copies of the journal Astropolitics as Eligar is the editor for it.

Please post your comments/questions on TSS blog above.  You can each Dr. Sadeh through me or his email address on his Report on the blog.

We welcomed UCSD freshman aerospace engineering student Darren Charrier to the show to discuss his UCSD SEDS projects including building a 3D rocket motor and a 6U cubesat communications center for their lunar lander. Make sure you see the video of his TED talk, www.youtube.com/watch?v=e9umkenQDoY.  In the first segment of our 1 hour 27 minute program, Darren started off explaining his interest in space, the Moon, and mining lunar HE3 to solve energy problems around the world.  He also explained why he decided to attend UCSD over other aerospace engineering schools.  We then got into the specifics of the three SEDs projects being worked on at UCSD by Darren’s team, the 3D printed rocket motor which was an existing program before Darren came to UCSD, plus the lunar lander and the 6U cubesat lunar orbiting communications satellite needed for their lunar lander.  The group intends to ride share to the Moon but it was too early to announce anything specific about that.  The timeline is by Darren’s graduation from UCSD in approximately four years.  We also learned that the 3D rocket motor will enter the competition later this summer in Green River, UT (we usually do a Space Show program on this event once the winners are known), plus their 6U cubesat bird will be entered in a NASA competition.  Darren was asked about his team and the UCSD administrative support for their projects, plus he was asked for specifics regarding the 3D printed rocket motor including its performance specs.  Darren talked about fuels that will likely be used by the 3D motor plus they may use a version of it to propel the lunar lander which they want to make a soft landing on the lunar surface.  Abut the lander, I inquired what it would do on the surface.  He said they would be pleased if it accomplished the soft landing plus survived a lunar day.  They want it to call home and take photos.  Our guest received several questions about the UCSD SEDS chapter as well as SEDS on a national level.  One listener asked him if they had ITAR issues, especially with foreign students.  Don’t miss his response to this question.  Bill called from Chicago to talk about Darren given he knows hm.  We learned much about this young, inspired student and future industry leader.

In the second segment, I asked Darren if he wanted to carry out his lunar plans as a private company or with government. He wants to be a private company with the government as a customer.  We also talked about Darren’s larger set of plans for the Moon including his starting a lunar landing business, servicing lunar tourism, additional mining over and above HE3 and more.   When asked about going to Mars, he said the path to Mars was through the Moon.  He supported asteroid mining but thinks it is far from being ready now and the path again goes through the Moon.  Doug called to ask more questions about the 3D motor and mining HE3 on the Moon. This latter subject was a major part of the Part 2 discussion with listeners as there were many questions about mining HE3, fusion development, HE3 on Earth, and even seriously using thorium rather than trying to develop lunar HE3 resources.  John from Ft. Worth called in on this and suggested using lunar HE3 for advanced spacecraft propulsion from the Moon rather than bringing it back to Earth.  There was plenty of listener interest in the fusion-HE3 discussion.  Returning to asteroid mining, Darren said one of his goals was to mine asteroids but that it was still a very long ways off.  He said “mine the moon first!”.  As the show was ending, we talked some more about thorium here on Earth, appropriate conferences for Darren to attend and he gave a shout out to his team members.

Please post your comments/questions on The Space Show blog  You can reach Darren through me.

Welcome to this two hour Open Line discussion on a variety of topics.  Note that while I took two breaks during the discussion, I am still archiving the show in just two segments.  During the first segment, my suggested discussion topics included my response to an April 10 email from Doug wondering why I strongly believe that the economic development of space will be a sizeable part of the future economy.  I answered this question for Doug on air and during the show a few listeners added to my answer.  My next suggested topic dealt with The Space Show website problems and the development of a new site to be funded by a crowd funding program.  I asked listeners for suggestions for incentives to offer contributors to the crowd funding venture. While most offered excellent and serious suggestions, one or two listeners responded with sarcastic comments and probably in their mind, funny comments.  But I am very serious about this.  The Space Show website is moving, we are trying to move the existing site to stay up with something that works and all of you are familiar with as a completely new site needs to be funded.  If you do have suggestions for incentives for supporting our crowd funding effort, post them on the blog or email them to me.  I appreciate this.  Our first caller was Andrew in Tucson who called from the top of Kitt Peak as he was there working two telescopes and doing observatory work.  We talked with Andrew about his work and project, the telescopes, life on Kitt Peak, light pollution in the area and more.  We also talked with him about other observatories in Tucson and Flagstaff, plus since he has been to Mauna Kea in Hawaii, we talked about that as well.  I planned a visit to him on Kitt Peak and will do some recorded interviews while there for future Space Show program.

We took a break at the top of the hour and returned to talk with Jeff from Tucson about his work with Andrew and his thoughts on the ULA-Vulcan project plus comments by the new ULA head, Tory Bruno.  I asked if he had read the recent Space Cynics post on ULA Vulcan by Shubber Ali who pretty much dissed the venture (see https://spacecynic.wordpress.com – the lead post).  Jeff briefly looked at it and said it lacked numbers and fact and was an opinion piece. What Jeff then had to say was based on engineering, numbers, and fact and he thought it was a good project.  Don’t miss what Jeff had to say about ULA Vulcan as it was a good call.  Jeff’s called sparked others to comment on both ULA and SpaceX and I made the case for needing both companies and more to help the emerging commercial space industry grow and develop.  I also commented that the one or the other mentality or moon vs. mars or being forced to make choices at the expense of other valid choices was counter-productive and not supportive of industrial growth yet I realize we are living in tight budget times.  We took another short break, then Tim called in to disagree with an earlier guest on the possible use of RTGs on the Moon and the use of material such as Plutonium 239 or substitute materials that may be cheaper and in more abundant supply.  Mike called to advocate for getting Ms. Shotwell of SpaceX back on the show, then Doug called to question the year long ISS experiment with Scott Kelly.  Rather than using a time line for the mission parameter, he wanted to suggest targeted objectives to meet.  While I thought his idea was a good one, I was at a loss how to suggest he go about getting changes in the mission design for this experiment.  I did suggest I would see if I could find who designed this mission and get them to be on The Space Show. If any of you have specific information on this, please let me know.

We welcomed Eric Berger to the program for a wide ranging discussion on US space policy, NASA, our space future, commercial space and more.  During the first segment of our 1 hour 37 minute show, Eric started the discussion by talking about his early interest in space, his contacting NASA as a child, getting back a great set of photos and other information and being hooked and excited about space ever since.  Some of the early topics in this segment included his surprise that we are not yet beyond low earth orbit with manned spaceflight, then he addressed why it is taking so long to go to Mars , why Mars is the next big step for humans and why going to Mars is so hard.  In his discussion of these topics, he referenced Elon Musk and the SpaceX Mars plans, even Mars One.  I asked Eric for his perspective on the NASA ARM mission which led to one of many discussion of NASA budget constraints and the idea that this or that project is all that can be done within the budget permitted by Congress.  Eric started getting lots of listener emails.  Jenkins wrote in saying that its not the budget that is the problems, the choices we make as a country regarding how we spend money that is the problem.  Eric then referenced the human spaceflight study released last year by the NRC regarding the likelihood that we will be living with tight NASA budgets for the foreseeable future.  Paul in New Mexico asked Eric about the impact of commercial space on policy and NASA.  Eric said it was an important impact so don’t miss his full statement.  Later in the segment, we talked about his seven part “Adrift” series last year and I asked him what his biggest surprise was in researching the articles for the series.  He said it was finding a shift in his view on SLS and that SLS could very well be an important part of our spaceflight future but that it needs to be funded to launch real programs.  He also said that maybe Falcon Heavy could do most of what SLS could do, especially in the Earth-Moon systems but that remains to be seen.  We then talked about the time it took to do various parts of Apollo compared to how much time it takes to do just about anything in space today.  Michael Listner called to talk about needing both NASA & commercial space and some realities involved in policy and space issues.  As the segment was ending, a Portland listener asked if competition with China might develop and force the US to spend more and do more in space.  Don’t miss Eric’s answer.

In the second segment, Eric was asked about space settlement being the goal and the purpose of our National Space Policy through a change in law per March Storm and other groups who are advocating this.  Eric was OK with space settlement but listen to his comments for the full context of his message.  He also said it was hard to figure out what to do with SLS but that some changes might be a full ten years out from today.  We talked about space technology advancements and then Gerald Driggers called in to say we had lots more work to do. For example, we talked about the need to fly a centrifuge in space to determine the gravity RX for humans.  The issue of the lack of space leadership came up from the White House down to the congress.  Many times our guest said it would take a change in leadership to get a change in space leadership but that just changing leadership does not mean the new leader(s) will care about or prioritize space.  Regarding commercial space, he went a bit deeper in this segment.  He said there was lots of commercial space activity but that NASA was still the center of it.  He made the case for the industry needing a broader base than just NASA.  I asked about a Europa mission and another listener asked he could articulate the Senator Ted Cruz view on space policy.  We talked timelines for humans to Mars and for a return to the Moon, he was asked if NASA should be eliminated in favor for a return to something like the old NACA, then Benny in Denver asked about the Texas spaceport facilities being developed for SpaceX and the Blue Origin facility.  As we neared the end of the program, Eric again stressed the difficulty in going to Mars, he looked back at our space history including Gemini 4, and he talked about the Obama policy from 2010 about not going back to the Moon though many in NASA do want to go back to the moon.  Bottom line was Mars around 2050.

Welcome to this two hour webinar regarding the choices and considerations that can be made in designing and configuring launch systems.  TO VIEW THE WEBINAR VERSION OFTHIS PROGRAM, GO TO https://vimeo.com/126223310.   Note that on the blog for this program are two Power Point presentations for your use.  Dr. Jurist referred to both of them during the webinar, especially the presentation titled “Choices: Some Considerations in Configuring Launch Systems.”  I urge you to follow along with them during the webinar.  During the first segment, Dr. Jurist explained the target market for the webinar and his two presentations.  He then talked about how hard it was to go to Mars and do other missions.  Then he got to the point by saying in designing or configuring the launch system for a mission, you started with the payload requirements which then provide additional constraints once the payload has been defined.  He also talked about the application of the basic rocket equation and explained the importance of exhaust velocity, the Delta-v, and the mass ratio.  Listeners started asking questions so two stage compared to single stage was discussed.  John pointed to the Choices presentation, slide 8.  He talked about propellant and pressures, both in a pressure fed system and with a turbo pump system.  Another listener asked about solids versus liquids, then Marshall called to talk about rocket g forces.  Dr. Jurist talked about designing the rocket envelope environment to the payload specifications.  He then brought in and discussed the vibration envelope.  Helen asked how things would be different with a human payload rather than a satellite or cargo.  Reliability was a big concern.  Near the end of the segment, Dr. Jurist talked about payload mass in Leo and BLEO.  Doug inquired about the gravity loss during the launch, then the segment ended talking about heavy lift, solids and proportional cost factors for SRBs.

 

In the second segment,  Penny asked how the variable that had been discussed would change were one launch from the Moon or Mars.  Adrian emailed in about the NERVA rocket and nuclear propulsion.  Dr. Jurist used the German V2 as an example of launching from the Moon.  Specific impulse and exhaust velocity came up again, then the focus turned to rocket motor cooling systems.  Questions continued coming in asking about 3D printing of rocket motor parts to lower the cost and the use of hybrid rocket fuels with their advantages and disadvantages.  Regulatory issues came up in this segment as did political issues, plus our guest got a question about amateur rocketry.  A listener asked about environmental concerns over rocket fuel . Dr. Jurist directed the audience to the Choice presentation, slide 22, and talked about ways to possibly shed some weight such as dumping the payload shroud.  Near the end, John got questions about the Falcon Heavy, Doug called in with questions about lunar lander economics and more.  In closing, Dr. Jurist said “the fundamental theme of the presentation was the many variables that come into play in designing or configuring a space launch system, how the many variables are inter-related, and how every decision in the process constrains or narrows the remaining options.”

We welcomed Dr. John Jurist and Kobi Hudson to the program to discuss their recent experiences at the Orbital ATK 5 segment booster test in Utah and the ISS algae experiment Kobi and his teammates are working on at this time.  During the first segment of our 1 hour 58 minute discussion, John and Kobi talked about viewing the Orbital ATK 5 segment booster test this past March in Utah.  John has attended all the 5 segment booster tests but this was the first one for Kobi who is one of John’s students at Rocky Mountain College in Billings, MT.  Kobi described the test, what it looked like and how it felt from the viewing area, the networking opportunities he had with those attending the test including many executives from across our aerospace industry & NASA.  I asked John and Kobi if they sensed that the Orbital ATK team was aware of the controversy surrounding the final destination for the booster, SLS.  We talked about this for several minutes.  I think you will find what both John and Kobi had to say about this to be very interesting.  This discussion took us into an SLS discussion but from a slightly different perspective than our usual Space Show SLS discussions.  A listener asked our guests if either of them noticed a cultural difference in the test team given the Orbital and ATK merger.  Kobi was asked if the test and the experience inspired him to want to work in the aerospace field which it did.

 

In the second segment, Marshall called to inquire about the use of liquid rocket motors as compared to solids and wanted to know which type was more efficient. Both John and Marshall seemed to agree that it might depend on which type of propulsion system gets more launches and usage though the solids are far simpler.  As part of this discussion, the political dimensions of decision making were brought up as they play a role in the propulsion system and thus influence efficiencies.  Next, we turned to Kobi to explain to us the algae experiment he and others are working and which will fly to the ISS on the SpaceX 7 launch.  Behind this experiment is the goal of testing how well algae grows and how much carbon dioxide it consumes in a zero-gravity environment.  They want to see if it can influence the presence of oxygen in the spaceship.  The algae is grown in an agar solid media.  Kobi went into details on this experiment which I believe you will find of interest. When the team gets the data back from the 28 day test, Kobi will come back to the show to update us on what they found out.  Later in the segment, SLS John called in to follow up on our earlier SLS conversation and the proposed NASA ARM.  Several listener questions came in by email regarding both the issue of solids vs. liquids and the algae experiment.  Kobi also got a question or two about this work on the Firebird cubesat program.  He said it used a polar orbit , was then asked if cubesats could go to the Moon or elsewhere and he said probably but challenging. Doug called to talk closed loop life support and related issues.  The last question came from a high school senior asking Kobi about the need to attend a Tier One school and the consequences for going to a school not as well known and not as highly ranked.  All three of us, Kobi, myself, and John responded to this question saying about the same thing but in different words.  Both John and Kobi offered concluding comments you don’t want to miss.

 

Please post your comments and questions on TSS blog above.  You can reach both guests through me.

John Batchelor and I welcomed back Rand Simberg to discuss the recent Falcon 9 launch and barge landing attempt of the Falcon 9 first stage. In addition to discussing these events, we talked about the recent SpaceX statements about trying to land the first stage on land at either the Cape or Vandenberg. Rand talked about what would be needed to do that. Next, we talked about the recent press conference and release of information by ULA regarding their Vulcan rocket project and their plans to recover the first stage rocket motor. Rand also had much to say about the CEO at ULA and the different direction the company seems to be taking.

We welcomed back Rand Simberg to the program. During the first segment of our 100 minute program, Rand discussed the Falcon 9 launch and barge landing attempt of the first stage. Before he finished his discussion, Dr. Lurio called in and joined in on the speculation as to why the landing was unsuccessful. Both Rand and Charles thought it might be wind but as you will hear, that was just their opinion. Next, the two of them turned to the ULA announcement about the Vulcan rocket and their plans to recover in air from a supersonic parachute using a helicopter. They want to recover the rocket’s main engine. This discussion between Charles and Rand dominated the first segment of the program. Near the end of the first segment, I asked Rand about the ARM and it being redirected to Mars and Phobos. Rand had much to say about this so don’t miss it.

In the second segment, in response to earlier comments made by Rand in the first segment, Sally sent in a note asking if the next NASA administrator might make a difference and actually matter. Again, don’t miss what Rand had to say about this plus bipartisanship and the work of Congressman Dana Rohrabacher who wants to change the our space policy to one of having the main purpose to settle space. Rand also said he would personally like to “ban” the phrase space exploration. Listen to his explanation on this point. Rand was asked about the Moon-Mars debate which he thought was absurd given that the issue was not about destinations but getting the needed infrastructure in space so one can go anywhere. Without the infrastructure, even a gravity lab, talking destinations makes no sense. Due to a few listener questions, Rand also had some choice comments for Mars One. Another listener asked Rand what parts of the commercial space industry impressed him the most. This led to a discussion about suborbital flight and markets. Becky asked him about his Transterrestrial blog (http://www.transterrestrial.com) and the non-space portion of it, I asked him about military space and then Tim called to talk about affordable small sat launches and to inquire if we were embarking on a space race over low cost launch opportunities that may be emerging. Rand also talked about the upcoming Space Access Society meeting and the talk he plans to give at the event. Rhonda in Petaluma asked Rand what caused his transition from traditional aerospace to NewSpace. Don’t miss this, it is really interesting.

Please post your comments/questions on TSS blog above. You can reach Rand through his blog or me.

We welcomed Chris Carberry back to the show to discuss Explore Mars events & activities. During the first segment of our 96 minute program, Chris started out by telling us about the upcoming Humans2Mars Summit planned for May 5-7 in Washington, DC. All the conference and registration information is available at http://h2m.exploremars.org. This discussion led me to asking him why we should go to Mars and why now. As part of this discussion, I challenged Chris on using tax payer money for a Mars mission rather than letting the private sector do it. In fact, he did get a listener question about this, suggesting that either Mars One or SpaceX take us to Mars, not the government. Eric sent in a note asking who we thought might be the next NASA administrator or at least who the candidates might be. He also wanted Chris to advise how best to influence officials, policy makers, members of congress, etc. to go to Mars. Chris offered several suggestions to this part of Eric’s two question email. Chris responded to emails about the Affordable Mars Workshop architecture for Mars that we have been hearing about over the past week, plus the recent NSS-SFF meeting where settlement seemed to be the agreed upon goal. Don’t miss what Chris had to say about these events as he attended both. Doug called from S. California to make the case for going back to the Moon on its own, not just as a stepping stone to Mars. Doug suggested that the lunar return folks team with the Mars folks to find the best way to do both missions as it should not be one or the other. He also wanted to make sure going back to the Moon did not delay going to Mars and that going to Mars did not delay or destroy the opportunities for returning to the Moon. Chris and Doug had a vibrant exchange on this subject, especially given this era of tight budgets & constraints.

In the second segment, John from Ft. Worth called to express a concern that going to Mars might end up like Apollo and after a few Martian visits, we quit that too. Chris explained why he did not think that would happen. Later, Dr. Lurio called and said that “these guys are ALL living in fantasy land, one version or another.” His call was to pick up from the email he sent us and to elaborate on his position which was hotly debated and challenged by Chris. One thing Chris and Charles agreed upon was that there would be no repeat of a so-called “Kennedy Moment.” As the show was ending, Chris went over the Humans2Mars Summit again and we talked about the need to start working on Mars plans rather than always just talking and “planning” about them.
