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. Pamela “Rai” Menges to the show. I suggest you visit her websites and follow along as applicable with our discussion. Visit http://arsispace.com/spacetechnology.htm and http://starsailorenergy.com. During the first segment of our 1 hour 47 minute show, Dr. Menges introduced us to Aerospace Research Systems, Inc. (ARSI) and talked about the company history dating back to its founding in 1993. We talked about research technologies, private R&D, government funding for research, and specific projects referenced by our guest including the Space Power Laboratory. At one point Dr. Menges discussed the pros and cons of taking government research money and why she elected not to do so. Also, the use of public relations (PR) and the role it plays with those accepting government money. After a brief mention and discussion of the possible space policy positions presented by Ohio Senator Rob Portman, we turned our attention toward power storage and the work our guest has been doing in this area for non-electrolytic power storage. Don’t miss this discussion. Another topic was the use of AC and DC power transmission, the Carrington Event in the 1800’s, and our electrical grid. Jack emailed about the spaceplane shown on the ARSI website, the Ramstar Model. Our guest had much to say about this experimental spaceplane concept and design. I

n the second segment, Ben in Boston asked about telemedicine commercial astronaut healthcare per the descriptive on the ARSI website. Pamela went into detail about this topic, their work with JSC and more. We then spoke to the issue of commercial astronaut safety in general with our guest expressing her thoughts of the safety issues within the industry and the regulatory environment. Later in the segment, the concept of ground effect vehicles came up along with advanced hypersonic technology and even SSTO possibilities. I asked our guest about nuclear propulsion and then several listeners asked her about it as well. Carol’s email took us on a different path as she asked about the need for lots of centrifuges for a peaceful nuclear energy program. This opened the door for our guest to speak about nuclear weapons, the current talks with Iran, and the treaty organizations that safeguard against proliferation. Pamela had much to say about this subject, our government, the Iranians, enrichment, centrifuges, trust but verify and more. Do not miss this discussion. Ft. Worth John called to ask about the use of centrifuges as opposed to other technologies such as gaseous diffusion. Near the end of the program, Luis emailed us about Reaction Engines and the Skylon project space plane. He too sent in a question about winged ground effect vehicles. Kristopher emailed us to check out “Caspian sea monster” on YouTube for an example of these vehicles. Dr. Menges talked about her new book that will be out in the near future and for Pearls of Wisdom suggested “doing what you want to do to pursue your dreams.”

We welcomed Chris Newman to the show to discuss British space policy, programs, their space industry and British space law.  During the first segment of our 88 minute program, Dr. Newman talked about space law and the space industry within the UK.  At times we compared British space law with that in the U.S., talked about the British interest in commercial space, space entrepreneurism and British government space as opposed to commercial space within the country.  As you will hear, British space is more about business and returns than government policy.  We also talked about social media and its value with some criticisms and supportive comments from me.  Mike Listner called and we did some comparisons with the British space law perspectives compared to American space law perspectives.  A listener asked if the British were fearful or concerned about the Chinese program and if they thought we might be in a space race with China.  Chris had interesting things to say in response to this question.  Chris talked about the role of the European Space Agency (ESA), competition from SpaceX with the Arianne rockets, and the ISS.  Toward the end of our segment, Alex emailed a question about the impact of our ITAR regulations on the British space, science, and technology industry.

In the second segment, I asked Chris how British citizens influence their government for space policy and matters as compared to what we do in the States.  Chris did explain the British system to us which is quite different , including their budget process.  Later I asked if the British government and people were enthusiastic about space companies, including Skylon with Reaction Engines.  You might be surprised by his response, especially when I asked if he thought the desired Skylon funding was possible.  We also talked proposed British spaceports and the possibility of British regulations on their developing space industry.  Later, George emailed in to ask if various segments of the British government competed for funding similar to what happens with the discretionary items in our budget.  Chris explained the process in more detail but the short answer was no as their budget process is quite different from ours.  Another listener asked more questions about competition in Europe from SpaceX.  Chris had much to say about this.  Other subjects discussed included a guess as to what future space missions will look like from the British perspective, more on the threat from NEOs, the global launch rate and Arianne making unrealistic market share projections, and the militarization and weaponization of space. Near the end, we talked about commercial space balloon/airship  projects like World View.  As for 2015 for British space, Christ told us to be aware of the May elections as that may set the tone for the space debate and programs for the future.  We agreed to follow up with Chris after the election to check on this.

Welcome to our Open Lines show.  During our first segment of this 2 hour 20 minute program, we mostly talked about both the recent Antares rocket explosion a few seconds after launch and the Virgin Galactic SS2 accident resulting in the loss of one crew member.  After my opening statement about not engaging in accident speculation and my reading an op-ed by Dennis Wing on the accident titled “Thoughts on the SS2 Crash” (http://denniswingo.wordpress.com), we opened the lines for callers. Dr. Jurist called first to strongly urge against speculation.  Michael Listner called & updated us regarding the Air Force-SpaceX litigation, then Michael talked about the SS2 accident & to guard against speculation.  He did give us the relevant parts of the commercial space law pertaining to the Dept. of Transportation and FAA having regulatory oversight of the suborbital industry.  He cited 51 U.S.C. § 50903(c) & pointed out this paragraph:  “(c) SAFETY.-In carrying out the responsibilities under subsection (b), the Secretary shall encourage, facilitate, and promote the continuous improvement of the safety of launch vehicles designed to carry humans, and the Secretary may, consistent with this chapter, promulgate regulations to carry out this subsection.”  Dr. Rowe called and talked about cardiovascular risks for longer spaceflights as well as the problems associated with using pharmaceuticals in space.  Bill also addressed some space tourism issues.  During this segment, I read an anti-space tourism article from Wired.com which you will see on the Dennis Wingo Blog as Dennis commented on the Wired article.

In the second segment, Kirk called from Trinidad.  He mentioned the SR71 flight breakup with Bill Weaver and the loss of the other pilot, plus I asked questions about the interest in space in Trinidad.  Dr. Dwayne Day called next to resist speculation on the SS2 accident, plus he shared some of his experiences in accident investigation and how things progress as he was part of the Columbia investigation team.  We then talked about really bad network and cable news reporting on both the Antares rocket failure and the SS2 coverage.   Dwayne recently did a tour of SpaceX and ULA so he told us about each one and highlighted some of the differences that he saw regarding each company.  I think you will find this discussion very interesting.  Dwayne mentioned early commercial spaceflight history, problems, and setbacks as points of reference for us.  Tim called from Huntsville about the SS2 crash and the Russian engine used by Antares.  He wondered if the British Skylon space tourism vehicle would be an alternative.  SLS John was our final caller who again urged against speculation on the cause of the accident.  He mentioned risks to the space tourism industry and concluded saying what others have said and that is that rockets are a risky business no matter what.

Please post your comments/questions on TSS blog above.  You can reach any of the callers or people mentioned on the show through me.

We welcomed back Sir Martin Rees to discuss his chapter in the new book Starship Century: Toward the Grandest Horizon, edited by James & Gregory Benford.  Sir Martin’s chapter, titled “To the Ends of the Universe,” looks forward through time and centuries to address human spaceflight, eventual interstellar travel, life extension & more.  In looking forward, he levies criticism on the past. We talked about several of his comments regarding our past & current space program. Dr. Rees mentioned the need for life extension though for Mars he said we could do that without life extension but we should not fool ourselves as it will prove far less comfortable than Mt. Everest or the South Pole.  We talked about finding planets & the possibilities for life, then we switched to the discovery of quasars soon to celebrate its 50th anniversary. Listeners asked our guest about his comments that the political impetus for current & future space work seems to have been lost, especially in contrast to the Apollo era.  In his response, our guest suggested we need low cost and reusable launch vehicles given how costly everything is today.  He commented that mining asteroids did not make sense other than for ISRU purposes. Before going to break, he was asked about the UK government investment in Skylon which he supported.

In the second segment, we spoke about changes in the UK space activity over the past decade.  Sir Martin made comparisons with the UK, ESA & NASA, especially regarding long term planning & our very short one year budgets.  He suggested our budget process makes us unreliable partners in many respects.  Quasars were again a discussion topic, plus Sir Martin fielded a question from a high school student wanting to know how we know the laws of physics are the same throughout the universe.  Another listener wanted to know about science fiction as a leading indicator for science.  Dr. Rees suggested some excellent books for those interested in reading specific science fiction works. James Benford, editor Starship Century called to point out the excellent reading list in the back of the book, plus he offered us important comments about the book & authors. Near the end, Sir Martin was asked to look forward 10-15 years & tell us his thoughts.  His response focused on finding even more planets around the stars, identifying more threatening NEOs, & even more attention given to life extension issues.  The last two questions asked our guest dealt with the ISS living beyond 2020 asking if that was valuable and also the recent podcast by Dr. Neil deGrasse Tyson that SpaceX would not be able to go to Mars.  Throughout the discussion, he mentioned the private sector doing things government could not, especially due to less risk averseness.

We welcomed Dr. Paul Abel to the program to discuss the BBC television show, The Sky At Night (www.bbc.co.uk/programmes/b006mk7h).  During the first segment of our 1 hour 31 minute program, Dr. Abel introduced us to the Sky At Night show which was started by Sir Patrick Moore in April 1957.  Dr. Abel described the focus and objectives of the program and we talked about some of their projects including the “Battle of the Forces” tug of war video which is on their website, plus their just completed Summer Solstice program which was filmed at Stonehenge.  We came back to talking about Stonehenge, mythology, rituals, and customs many times throughout the discussion.  I asked Dr. Abel about British commercial space companies such as Surrey Satellite but since they are publicly funded, their focus and goals are different as they address mostly space and science topics.  Dr. Abel talked about the many British astronomical societies plus the overall interest in astronomy and these societies within the UK.  We talked some about human spaceflight, including the Mars One venture.  Listeners asked about astronomy and telescopes and we learned that our guest is not in favor of what he called “go to telescopes.”  Instead, he suggested we should learn how to map the night sky and navigate our way around it with an equatorial telescope.  Listeners also wanted to know about observing and dark skies in the UK.  I asked questions about the relationship of astronomy and theoretical physics.  Another listener asked for a definition of Hawking Radiation.  Comets came up along with their mythology, plus the Kepler Space Telescope and Voyager 1.

In our second segment, Ben asked about SETI in the UK.  This started a rather involved and fun discussion about ET and the search for life using radio telescopes as well as by other means.  Also mentioned in this segment was amateur astronomy as compared to professional astronomy, Star Trek & its devices such as the transporter.  Paul received questions about his home observatory and telescopes.  A possible Europa mission was mentioned and we were both excited about that potential.  I asked our guest about STEM issues in the UK & observing in London’s Regis Park.  Sine we had spent some time talking about the search for life and ET, we talked about some ET sci-fi movies including Contact, Alien, & Star Trek.  As we were about to end, Tim called wanting to ask more about Skylon, a possible UK launch site near the equator, and the emerging UK Space Agency.

Our program today was a 2 hour 5 minute Open Line discussion.  I started it out with some Space Show announcements, suggested topics for today’s discussion, then I opened the phone lines for listener participation.  Dr. Doug Haynes was our first caller. Doug is celebrating the tenth anniversary of Blue Ridge Nebula Starline (www.blueridgeairlines.com) and his sister site, www.bluenebula.com.  Dr. Haynes talked about his vehicles, missions, propulsion, AST, orbital, suborbital and all HSF, his issues with zero gravity, green space technology, spaceports with the Front Range Airport as well as Denver International. Follow our discussion about his vehicles and pods via his Blue Nebula website above.  Doug also told us about his books through the 3rd Wave Air Books which is linked to both his websites.  I did mention Doug’s very well known newsletter & how to visit his operation for those in and around the Denver area.  Our next caller was Dr. Doug Plata from Southern California to discuss space radiation and our Monday guest, Dr. Marcelo Vazquez.  Doug took us through several radiation risks and mitigation strategies.  We talked about radiation and the Mars missions plus what might & might not be appropriate regarding taxpayer money or the cash equivalent regarding helping a private company do a HSF to Mars.  Just before the break, questions came up about the upcoming SpaceX Falcon 9 Vandenberg launch.

In our second segment, Tim Weaver was our first caller to talk about Skylon.  There has been some recent press suggesting that the UK government my be interested in some funding with Skylon (www.sen.com/news/uk-pledges-fresh-support-for-revolutionary-space-engine.html).  We talked about the UK space interests and program along with the astronaut safety issue mentioned earlier and by Rand Simberg in his recent program.  John Hunt called in to talk about the Zubrin article on NASA’s asteroid retrieval mission, then he said he doubted anything would become of Skylon.  His last point pertained to astronaut safety per the Rand Simberg show and comments.  He suggested that since the government flies astronauts for national prestige, safety would be extreme given the potential prestige damage resulting from an accident.  Before the end, Doug sent in a note saying the Falcon 9 Vandenberg launch is currently set for Sept. 5th.

Please post your comments/questions on The Space Show blog.  You can reach any of the guests who called in today via their website or my email address.

We welcomed Sarah Cruddas to the program to discuss space development and policy from the British perspective.  Please visit her website, http://sarahcruddas.com for more information.  During the first part of our 90 minute discussion, we talked about space policy, science, and commerce from a British perspective.  Listeners asked many questions about the UK perspective on space mining via Planetary Resources, commercial satellites & Surrey Satellite Technology, plus NASA projects like the Kepler Space Telescope and the search for exoplanets.  We talked with Sarah about commercial space travel/space tourism with Virgin Galactic, especially since Sir Richard Branson is British.  Sarah was asked about UK entrepreneurial space ventures and the Isle of Man.  Sarah also covered the last space shuttle flight at KSC. She told us it was a very emotional experience.  We also talked about the British perspective on both the ISS & the Hubble Space Telescope.  Listeners asked our guest about space programs, interests, and policies in Germany, France, and ESA.  She told us that the UK participation in ESA was smaller than that of other countries so their space programs are less ESA-centric.  Sarah was asked about HSF to Mars including Mars One and the Inspiration Mars flyby mission.  Doug called in to ask about Skylon & I talked about the early space history with the British Interplanetary Society (BIS) and space planes.  Returning to the topic of space tourism, she said it was too expensive for most people in the UK but there were some who have signed up and are interested in the adventure.  We talked about STEM education in the UK & and compared STEM issues there to here in the States.

In our second segment, we talked about space debris or space junk.  We then talked economics and UK, European, and global budget issues.  Sarah made the case for the importance of continuing to invest in space and science despite these problems.  Don’t miss what she had to say about space, our future, and economics.  We also talked about space media and journalism in the UK & the need for the West to be in the lead in commercial space development.  We spent a good part of this segment talking about the Chinese space program, plus India’s program.  Other topics included N. Korean rocket launches, the Google Lunar XPrize, Yuri’s Night in the UK, and even ET’s!  I asked about the popularity of astronomy& telescope clubs in her area, and the popularity of the ISS.  Toward the end of our discussion, I asked our guest for a ten year perspective on space.  Don’t miss Sarah’s future vision which included mining, space tourism, space junk resolution, and the growth of the Chinese space program.  She talked about returning humans to the Moon – with China.  She also said that people see space leadership and progress being made but that it was more likely to come from the Chinese than with we Americans.

Guest:  Robert (Bob) Zimmerman.   Topics:  Recent space news and announced projects.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://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 show.  Check out his blog at www.behindtheblack.com.  We started off our first long segment (90 minutes) by mentioning the 50th anniversary of Telstar 1, the death of our friend, Al Zaehringer, AT&T and our early space program, plus the word coming from CERN that they may have found the Higgs-Boson particle.  I then asked Bob to comment on the global warming statements being made about the current East Coast heat wave, followed by comments by Newt about the power grid outages and a taste of what an EMP would be like.  We then turned to space and Bob talked about the recent success with Dragon and Falcon 9.  He then talked about government space programs as compared to private programs.  Throughout our 135 minute discussion, he reiterated his opposition to space programs, making it clear that he does not want a “program” and why.  Let us know on the blog if you agree with him.  Bob suggested we were in a period of space revolution and that it would be very exciting over the next five years.  He talked about SpaceX compared to the Russians and the Chinese.  He did say we were in competition with them for control of space and this led us to a discussion about culture and the space frontier.  We talked about recently announced projects, Planetary Resources, Mars One, and one by the B612 Foundation.  He thought B612 was the only real one of the three.  Terry called from Texas to discuss using an Orion for a LEO mission, the Falcon Heavy for a Moon mission, Delta IV heavy and SLS.  Jerry called in from Florida and among our topics were frontier development, the Oregon Trail, the CERN reactor in Switzerland rather than in Texas, and more.  No space programs per Bob’s preferences again came up.  Let us know your thoughts about these issues on the blog.  As the segment ended, Bob was asked about Skylon which was the subject of yesterday’s program.

Tim’s call started our second segment & he asked about a lox paraffin hybrid rocket motor. We also talked about the space shuttle & its capabilities.  While Bob praised aspects of shuttle, he said the program was a failure.  I did not agree with him but listen and let us know what you think regarding this issue. Note that as the program ended, Martin sent us info on the hybrid motor mentioned earlier by Tim so check out  www.youtube.com/watch?v=o9erCLJ5KVg as Brian Cantwell delivered a presentation at Stanford on the state of the art of hybrid rockets.  Bob then updated us on the bat situation with the white nose fungus. As our program ended, Bob talked about upcoming events starting with Orbital’s Cygnus/Antares debut, Dream Chaser and other competitors.  He had some brief comments about the suborbital industry and citizen science projects and concluded by saying we were no longer in a holding pattern re commercial space.

Guest:  Mark Hempsell.  Topics:  Reaction Engines, LTD & their Skylon space propulsion system.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://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 Hempsell for Skylon updates and progress reports since his last visit on August 6, 2009.  During our first segment, Mark started with an update saying they are nearing the end of the technology development stage for their space vehicle system.  We then went back to the basics and he described the Skylon project for us.  Mark talked at length about the Sabre engine, the radiator, their SSTO plans, and more.  Several listener emails came in wanting to know about the market and business plan model for Skylon, the space tourism module and profile, and if it could be used for point to point transportation.  We learned that for cargo, Skylon flies without a crew.  With passengers on board, there will be a crew.  Also discussed were orbital characteristics for the vehicle, docking with the ISS and the new ISS docking standards which may present problems for Skylon. You can check out these standards at http://internationaldockingstandard.com.  Mark mentioned the various rocket fuels, tonnage to LEO and GEO, crew and passenger configuration, and the two day turnaround period.  In the second segment, we resumed talking about the vehicle operating costs.  Michael called in to talk about emergency landing options given runway constraints discussed in the first segment.  Next up was the thermal protection system (TPS) and we learned that the skin was a type of glass, silicon carbonate that can take1,000 C and that is why Skylon is black.  Later, we talked about funding, government subsidies, & private investment.  Mark got a question about using scramjet technology and he had much say about this.  Another topic was the flight profile and G-loads to be placed upon Skylon occupants.  Near the end, we talked about ITAR and potential U.S. investor investment.  Skylon test flights will likely be in 2020.  Our guest also talked about ESA and other organizational oversight.
