We welcomed Bob back to the show for the last time in 2015.  During the first segment of the 2 hour program, Bob started our by remembering Apollo 8’s flight around the Moon on Christmas Eve, plus he talked about his new edition Kindle version of his classic book, “Genesis: The Story of Apollo 8.”  Bob spent some time retelling the full Apollo 8 story, how it came about that Frank Borman and crew decided to read the first twelve chapters of Genesis for the huge broadcast that was heard around the world, then he contrasted the astronaut’s freedom to choose their own words to what he expected would prevail today.  What do you think?  Post your comments about this on the blog.  After the Apollo 8 story, we discussed the return to flight by both Orbital ATK and SpaceX.  Bob shared his perspectives about this plus his rational for NASA wanting to work with possibly four companies for commercial spaceflight for cargo to the ISS.  Caller Richard Easton was next to talk about Apollo 8, then he wanted to know Bob’s thoughts on the need to first go to the Moon before going to Mars. This turned into a mini-discussion that included reference to the NASA Roadmap to Mars, the Elon Musk plans to go to Mars and why, along with giant rockets, with Bob commenting on why giant rockets would be inefficient and not necessary. His call consumed the balance of the first segment.

 

In the second segment,  I read an email from Doug asking about ISS plans and the possible impact on a Bigelow space station.  Jody emailed in a question asking about the space positions for the presidential candidates for both parties.  Bob limited his comments to Mrs. Clinton, Mr. Trump, Sen. Rubio, and Senator Cruz.  In the process of talking about their positions, he went after big government programs such as SLS and Orion.  Jack sent in a question asking about recent XCOR changes in management.  Bob had much to say about this, though it was more about the company in general and the industry.  He did take the opportunity to applaud Blue Origin.  Doug called the show and his call consumed almost all of the balance of the second segment.  Bob and Doug had a grand old time planning missions without heavy lift rockets using multiple launches of the F9, ion & solar propulsion.  I refrained from entering their discussion and let the two continue until we needed to move on near the end of the show.  Bob was again critical of SpaceX wanting to build giant heavy rockets for going to Mars saying FH was large enough and efficient.  The assumptions the two made were in my opinion very generous but at least we know where Doug and Bob stand on these issues.  If you have comments about their discussion make sure you post your comments on the blog.

 

Please do post all your comments/questions on TSS blog above.  You can reach Mr. Zimmerman through his website, www.behindtheblack.com.  You can reach any caller or emailer through me.

We welcomed back to the show Dr. Doug Haynes for updates with his Haynes Saucer, Blue Ridge Nebula Starline, Blue Nebula company and his work to fly to Mars offering airline like service.  During the first segment of our 1 hour 16 minute program, Doug went over the history of his aviation and space business development.  He talked about Phase 1 in the 70s, Phase 2 in the 90s, and Phase 3 which is his current phase.  He said his Haynes Saucer was certified by the FAA and the number was 7111NH.  He also talked about his previous work with DARPA and composites.  In response to a listener email, he said he currently had an experimental certification but would transfer to a regular certification soon.  Jack asked him about visiting his facilities. Doug suggested attending his Open House programs which he holds a few times a year. He also talked about the potential of private visits to his Colorado facilities.  I asked him about the size of his operations and how many people he employed.  Doug listed the positions and team spots & said he was still growing.  Terry asked him about his saucer propulsion. Doug said it had three different aspects to it but in general it was ion propulsion with constant 1 g acceleration using gravitics. He said his hover craft used tip drive.  Later, I asked how he generated electricity for his saucer.  Don’t miss his response to this question.  Shelly asked him about human medical factors such as microgravity, radiation, etc.  He said he does not worry much about them due to his very fast transit times with his advanced gravitic propulsion.  Again, don’t miss his full response to this question.  As for vehicle size, it is roughly 9 passengers or less with a crew size of 2, all in his ejection pod which you can see in the pictures on the website as a huge glass like bubble on the top of the saucer.

 

In the second segment, he was asked about his pilots having space flight experience.  He said this was not necessary given they are running an airline plus his very fast propulsion.  Don’t miss all of what he had to say on this.  Clark in Chicago emailed in about the need for heavy lift re payloads & useful payloads to Mars.  He said he was running an airline so he goes orbit to orbit but again, don’t miss all of what he had to say n this topic.  He did explain how passengers would get to the Martian surface, then he was asked if he was cooperating or at least talking to other space companies for participation.  He mentioned Mars One several times as a possibility.  The next subject was ticket prices.  He explained that he was pricing his tickets using the same format as airlines, revenue per passenger mile.  He was going to charge $5 per revenue mile.  I pointed out what it would cost to do a one way 60 million mile flight (not including trajectory distance for reasons you will understand when hearing this conversation), then later he said he would be charging a flat fee of $2 million for the trip.  Spaceports were the next topic as he has been working on establishing the Colorado Space Port at the Front Range Airport near Denver International.  Doug talked about horizontal takeoff and landing only, his escape pod, his takeoff, igniting his engines about 45,000 feet to go to space.  Wayne asked about the Dept. of Defense interest in his project and he said he had been in touch with DOD officials and those channels were open.  Near the end of the show, I asked Doug to explain his E-drive AAMPP which he did.

 

Please post your comments/questions on TSS blog above.  You can reach Doug or subscribe to his email newsletter by using the email address on his websites in the right hand corner.  He uses the “dehas” email.  If you want to subscribe to his newsletter, which I strongly recommend for its entertainment and interest qualities, tell him you heard him on TSS.

John Batchelor and I welcomed Dr. Robert (Bob) Zubrin to the program to discuss the NASA Road to Mars per the Evolvable Mars Campaign: Status Update as published Sept. 22, 2015 by NASA Spaceflight.com at www.nasaspaceflight.com/2015/09/sls-manifest-phobos-mars-2039. John and I asked Bob about parts of the plan including 41 SLS launches, cislunar development missions, a mission to Phobos and then finally in 2039 a Mars surface landing. Bob was highly critical of all stages of the plan. He also said it was the subject of a big debate at the recent Mars Society Conference. You can see the debate Dr. Zubrin referenced at www.youtube.com/watch?v=Oo4-ros2yEk&list=PLn0lnGc1SaimPHpRoH0XlwiCih-jYjC7F&index=11. Bob called the NASA plan absurd, was highly critical of plans to go to Phobos saying the science was at Mars, not on Phobos, plus he described orbital challenges and difficulties created by going to Phobos. Several times he said the plan was nothing more than a way to spend money on NASA projects. Near the end of the segment I asked Bob about the plan being sustainable and also leading to the settlement of Mars. You can imagine his response to my questions. In summary, he said a humans to Mars mission needs to be done from start to finish within the two terms of a president, not spread out over 25 years as is the case with the NASA Road to Mars program.

We welcomed Rand Simberg back to the show to discuss his recent successful Kickstarter campaign, “Clearing The Roadblock To Mars.” Check it out at www.kickstarter.com/projects/1960236542/clearing-the-roadblock-to-mars. During the first segment of our 1 hour 32 minute show, Rand introduced us to the purpose of this campaign which was to show how much better and wiser NASA could use the funds now being spent on SLS. Or as Rand said throughout our discussion, to get more bang for the buck. Of course this assumes NASA would use the savings wisely. In this segment, Rand spent considerable time addressing the lack of SLS missions, the types of missions SLS might be used for but so far no such SLS missions have been settled on, plus he talked about having more efficiency by using smaller rockets, more launches and fuel depots. He also said we were not serious about space as evidence by the SLS program. Several listeners asked him about the trades between heavy lift and a smaller rocket, the risks involved, costs and more as this is a common debate topic in the industry. Rand said the debate would eventually be settled by market forces. I added in that the characteristics and performance of the rockets being used to settle the heavy lift or not question will also factor into any conclusions reached on this subject. Rand then talked about the Aerojet Rocketdyne announcement that they wanted to acquire ULA for $2 billion. This led to an additional discussion about the Atlas rocket, Russian rocket engines, Vulcan, and Blue Origin. He also answered specific questions about his Kickstarter project which he said was to show how much more could be done wit h the SLS money rather than spending it on SLS. In response to listener questions wanting him to compare SLS to Falcon Heavy, he said about three Falcon Heavy launches would equal one SLS launch. He advocated SpaceX do an Apollo 8 type of flight with the Falcon and Dragon but then said it probably would not happen because of their relationship with NASA.

As we started the second segment, Dr. Doug called from S. California to inquire about the technical capability of SLS and Falcon Heavy plus the ULA Vulcan medium to heavy lift rocket. In addition, Rand discussed the reusable Vulcan concept as compared to the SpaceX concept of landing on a barge. Rand was asked about the need for heavy lift for Mars. He made it clear he was not interested in Mars per se, instead, he wanted to lower the cost of space access to make it possible for anyone to go anywhere in the solar system, including Mars. Rand said over and over again that he was destination agnostic. He continued getting questions about heavy life vs. many smaller rocket launches. Rand said things like it was too risky to put all your eggs in one basket, i.e. the one big heavy lift launcher. Several listeners wanted to know the best path to try to influence the direction of space policy. Rand focused on congress and suggested visiting local congressional offices. Other listeners asked him about a possible increase in the NASA budget. He said money was not the issue for NASA. The issue was using the money wisely to do more with it than we are doing now. He repeated many times during the program that we were not going to have a replay of the Apollo program. Don’t miss his comments on this as they are scattered throughout our discussion. Near the end of the show, Rand was asked about the 2016 elections and space policy, rocket staging, even SSTO rocketry. When offering us concluding comments, he repeated we would not be repeating Apollo, that it was never that popular and much about it is a myth. Don’t miss what he had to say about the Apollo program and missions.

Please post your comments/questions on TSS blog above. Rand can be reached through me or his blog, www.Transterrestrial.com.

We welcomed Charlie Precourt back to the show to discuss SLS-Orion progress and milestones, human spaceflight, technology advancement, & much more. During our one segment 63 minute discussion, I first asked out guest about the Orbital ATK merger and business under the combined companies. We soon shifted to the SLS-Orion discussion which included information on the 5 segment solid rocket booster (SRB), tonnage to escape which our guest explained, possible missions, and opportunities that will become available as a result of having this heavy lift rocket available for missions that need the lift & high energy capacity of SLS. We talked about shorter travel times, larger payload mass & volume, plus higher energy transfer orbits using SLS as compared to an EELV. Charlies was asked about SRB safety for human spaceflight. Don’t miss his comments on this issue. He talked at length about the benefits of marrying the SRB for lift out of a gravity well to liquids for propulsion once in space. Our guest provided statistics on SRB launches and uses to support what he was telling us. Charlie also talked about his Space Shuttle flight experience and the Shuttle’s SME, especially when there was an SME problem on one of his shuttle flights. We talked about going BLEO and he introduced us to the concept of One Space. As a result of listener questions, our guest talked about SLS costs, its design for multiple destinations and missions, and the launch “sweet spot” that it would fill. BJohn asked if there were uses for an SRB or solid rocket motor in space. Charlie said for liftoff from a gravity well, yes, but otherwise the SPI for a solid was likely too low for in-space propulsion. I asked our guest about Orbital ATK meeting the SLS -Orion milestones and upcoming flight testing. Jeff from Tucson called in about the use of modern technology including light weight epoxy material for SRBs & other spaceflight hardware. Near the end of the program, I asked Charlie about the justification for HSF to see what he had to say about it. Don’t miss his reply. We then talked about technology challenges in going to Mars, choices that were made to do the shuttle and ISS over deep space missions, and destinations that were still Earth dependent as compared to those being Earth independent such as Mars. Jack emailed in a question based on a show earlier in the week where the guest said that for putting SPS infrastructure in space, SLS was too sophisticated. What was needed was big rockets that had a 2% failure rate as that rocket would be lots cheaper than an SLS. Charlie did not specifically comment on SPS infrastructure but did take issue with the notion that it would be fine to have a rocket with a high failure rate to make it cheaper than something like SLS. Listen to how he explained this. Tell us what you think on TSS blog. As the show was about to end, a listener ask Charlie, based on his F15, Air Force, and test pilot experience, what he thought of the new F35 Joint Strike Fighter and the shortcomings of the new fighter that are reported in the press. Charlie had interesting comments about this so don’t miss them.

We welcomed back Dr. Jim Woodward to the program to discuss the Mach Effect, Mach thrusters and drive, and breakthrough propulsion. During our discussion, Dr. Woodward mentioned his book, “Making Starships and Stargates which you can order at http://ssi.org/exotic-propulsion-initiative as this allows SSI to get a royalty payment on the sale of the book. If you buy the book through Amazon using TSS/OGLF portal, The Space Show gets a percentage of the sales price of the book. In addition, the Charles Platt article, “Strange thrust: the unproven science that could propel our children into space” can be found here: http://boingboing.net/2014/11/24/the-quest-for-a-reactionless-s.html. Finally, Dr. Woodward mentioned the paper written by Dr. Heidi Fearn, “New Theoretical Results for the Mach Effect Thruster.” You can download this paper at www.researchgate.net/publication/280134421_New_Theoretical_Results_for_the_Mach_Effect_Thruster. Note that in the final minutes of our program, Dr. Woodward spoke very softly and we were unable to get some of what he said as part of his final comments. While the 1 hour 56 minute program was divided into two segments, this summary will be in one segment only and short as the papers above tell the story. I urge you to read them and become familiar with Dr. Woodward’s work either before or after listening to this discussion which was at times very technical and heavy in the theoretical physics fields for gravitational forces, electromagnetic forces and more as he described the Mach Effect. In addition to the physics, since Dr. Woodward’s work is dependent on funding so he spent a good amount of time in both segments answering questions and telling us what it was like trying to get funding, approved proposals, etc. for cutting edge work or even work considered to be out of the box or on the fringe. His realistic assessment of the challenges posed by his and similar work goes to the point of why we don’t see more out of the box science & advanced projects being financed. In addition to the physics and funding discussions, we talked timelines for his having commercial uses for small Mach thrusters which would start off servicing satellites. This discussion covered both segments.

Please post your comments/questions on TSS blog above. You can contact Dr. Woodward through me at drspace@thespaceshow.com or his Cal State Fullerton website.

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 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.
