We welcomed back Dr. Chris Impey for a one hour one segment discussion about his two recent books, “Dreams of Other Worlds: The Amazing Story of Unmanned Space Exploration,” and his newer book “Beyond: Our Future in Space.” We started our discussion with Dr. Impey describing “Dreams of Other Worlds” which describes 11 unmanned space missions that have made a difference in our understanding of distant worlds. We focused on a few of the 11 missions including Viking, Cassini, Voyager, & the WMAP mission. I asked Dr. Impey what would have been included had the book been written later. The Dawn Mission would have made it, so would the Kepler Space Telescope, New Horizons, Curiosity, and probably others. We then switched to the use of ground based telescopes and here Dr. Impey talked about how many of the telescopes are being repurposed for a new life doing different types of observation astronomy. Dr. Impey was asked about his favorite missions. He mentioned Viking and the WMAP microwave telescope mission and this led to his talking about The Big Bang, dark matter, and dark energy. I asked Chris about the recent article in The Economist about the two Chicago area scientists proposing a new theory on dark matter. Chris had read the article and had some interesting commentary on it and the proposed theory. Robert sent in an email asking our guest why there have been no life detection experiments on the NASA and other planetary missions. This sparked a good conversation on the subject which you do not want to miss. Chris proposed a very plausible reason why no suck experiments have been carried out but let us know what you think by posting on the blog. Another topic discussed was planetary protection. Linda from Austin asked our guest about the UofA astronomy and cosmology programs and students, then Bill asked our guest if he had read “The Martian” or seen the movie. Chris had both read the book and seen the movie which we discussed for several minutes. Don’t miss this discussion as Dr. Impey made some interesting points about both the book and the movie and the plausibility of the story line including the initial dust storm which caused the problems for The Martian. Before the end of the program, Chris fielded some questions about future missions. We addressed the Europa Clipper mission but he said many may be disappointed for what was not being included on the mission so again listen to what he had to say. He suggested a Titan mission would be interesting. In his book “Beyond” Our Future In Space,” Dr. Impey addressed the new commercial missions & human spaceflight. Chris guided us through all sorts of possibilities for future human spaceflight. Nuclear propulsion came up with Dr. Impey having much to say about how beneficial it would be if we had it though it was still futuristic. We spoke of advanced technology & the Decadal Survey and its impact on the type of science projects that get undertaken due to funding. Will sent in a note asking about the recent article about Elon Musk wanting to get to Mars in 10-15 years given the various risks Earth faced, including extremism. Dr. Impey also said it was probably unrealistic to think that one could have a $500k ticket price for Mars, another part of the Elon Musk article. Dr. Impey offered us good summary comments so don’t miss them. The last question dealt with a possible science backlash and referenced the following Huffington Post article: www.huffingtonpost.com/entry/solar-farm-suck-up-the-sun_566e9aeee4b0e292150e5d66.

We welcomed Michael Listner back to the show for the last time in 2015.  During the first segment of our two hour discussion, Michael started the 2015 annual space law review by jumping right in to discussing the new Commercial Space Launch Competitiveness Act recently signed into law by President Obama.  In this segment, he hit on key issues including legal jurisdiction on issues would now be federal law issues, the solidification behind SLS making it harder to cancel the rocket project, and the controversial “property rights” section in the asteroid part of the legislation.  There were many questions for Michael regarding the significance and meaning of issues now falling under federal law.  During this discussion, Michael used legal definitions and terminology and we discussed hypothetical situations to try to understand the impact of federal over state law on issues likely to make it to court.  Michael again talked about the asteroid mining part of the legislation (he did so as well on his last show a few weeks ago) which he believes contradicts the Outer Space Treaty.  Michael carefully went through the legal issues including the incorrect comparison of the Outer Space Treaty to the oceans and the Law of the Sea Treaty rather than a more appropriate comparison to legal regimes regarding Antarctica.  Michael posted a good article on this discussion his blog, Space Thoughts, which you can read at https://spacethoughtsblog.wordpress.com/2015/12/11/section-51303-the-oceans-are-not-the-equal-to-outer-space/.  Later in the segment, listeners asked about domestic vs. international legal enforcement of the asteroid mining issues per the legislation, plus many questions came in about The Outer Space Treaty and even The Moon Treaty came up for discussion.

 

In the second segment, Michael started out by saying that SLS got a big boost which was supportive of commercial space policy.  Jack asked about commercial crew in the legislation, but our focus moved to the RD180 engine because that is a big deal right now.  Michael said it was akin to open warfare between Senator McCain and ULA.  Michael offered us a detailed explanation of the RD180 issue and how it can impact ULA, SpaceX, and actually impact the nation.  Another topic was the return to flight using the Atlas 5 and the RD181 engine for the Cygnus by Orbital ATK.  BJohn and later Freemont John inquired about nuclear propulsion and some of the things discussed in the recent program with Dr. Dewar. Another topic discussed was planetary protection which he said gets its authority from Article 9 of The Outer Space Treaty.  Before the program ended, Michael gave us a status report on The Code of Conduct, the suborbital industry, and the Moon Treaty.

We welcomed back Dr. Marc Rayman to the show to discuss the Dawn Mission and Ceres updates.  During the first segment of our 1 hour 25 minute discussion, Dr. Rayman said that Dawn was as close to Ceres as it would ever be & that it was in a stable orbit that would last a very long time as they need to avoid having the spacecraft crash into the surface of Ceres.  Dawn is approximately 240 miles above Ceres and its orbital velocity to maintain this orbit is around 600 mph. It takes about 30 minutes for a radio signal to travel one way between Ceres and Earth for a one hour round trip time.  He discussed this Ceres stable orbit in some detail.  We talked about the mission end for Dawn which will likely happen sometime in 2016 as the thruster hydrazine fuel runs out.  He described the failure to us and why they cannot predict with certainty the end date an time.  Marc also talked about the reaction wheels (gyros), the fact they lost two but had one spare to use. He explained how they have been operating the spacecraft with just two gyros instead of the required three.  We talked about some of the new information coming back, exciting findings by Dawn and of course the mysterious bright spots.  Marc commented about the mountain Ahuna Mans which rises to about 20,000 feet above the surface.  Doug called to ask about the water ice and the dark cracks he saw in the photos of the bright spots.  He also inquired about a human mission to Ceres.  Listeners brought up private human missions, including the possibility of a private human mission to Mars.  Don’t miss what Dr. Rayman said about these potential missions.  In response to a question about what would humans do on Ceres, our guest said EXPLORE! BJohn wanted to know if Vesta and Ceres had a special alignment making the mission possible or if we could pretty much visit any two asteroids as we did with these two (dwarf planets).  Doug emailed in asking how the astronauts would actually get around on the surface of Ceres, a question which led to discussing Ceres gravity.

In the second segment, I asked Marc how he and the others associated with these very long term planetary missions develop the patience to wait years and years for the spacecraft to arrive at the destination and start doing what it was designed to do. Marc had some interesting comments and observations about this.  Jerry asked if nuclear propulsion would benefit missions such as Dawn and planetary science in general.  Helen wanted to know what was the most disappointing thing about Dawn.  The reaction wheel failure was a big item but Marc had interesting things to say about defining something related to a mission as a disappointment.  Another listener asked if JPL tracked the general population popularity of its planetary missions.  Later in the segment we discussed robots vs. humans for some missions, then Jane asked about public school text books containing this cutting edge planetary science information.  Both Marc and I offered comments on this subject.  Marc also suggested we visit www.spaceplace.nasa.gov.  Another listener asked for the best school study path to pursue to be able to do what Marc does today at JPL.  Marc had lots of interesting things to say about this so if you want to do planetary science, note what he said. There are multiple study paths to take that can lead you to this kind of work at JPL & other centers/institutions.  He also noted that JPL has lots of non-technical people doing key things in the planetary science department with missions so the path is not always science and engineering.  Paul offered up the last question inquiring about the volume of data to be studied from Dawn.  Marc directed our attention the JPL Planetary Data System Repository which is where this information ends up and anyone can access and research it.  There are years if not decades of research awaiting for the Dawn Mission data.

Please post your comments/questions on TSS blog above. You can reach Dr. Rayman through JPL or me.

We welcomed back Dr. John Jurist to present his popular talk, “The Space Program of the 1960s.”  I have uploaded to The Space Show blog his Power Point presentation that he uses with this talk  so be sure to visit it.  He refers to many of the Power Point slides during this two hour Space Show program, especially slides featuring historical pictures.  The specific URL for this program on our blog is https://thespaceshow.wordpress.com/2015/10/24/dr-john-jurist-sunday-10-25-15.  During the first segment of our two hour program, Dr. Jurist discussed the origins of our space program going back to the 1920s with Robert Goddard and his rockets, and even earlier to Tsiolkovsky with the rocket equation.  John then advanced the story through WW2, V2 rockets, the development of the hydrogen bomb, the creation of the NSF, then on to Sputnik and the eventual launch the first American satellite.  During this overview, Dr. Jurist received many listener questions as well as questions from me so this is quite the comprehensive discussion.  John also pointed out the interest in space from the public which drove media coverage.  He referenced Walt Disney, von Braun’s popular work, sci fi films, & Colliers Magazine articles.  He mentioned several stand out events such as JFK’s Rice University speech, the Apollo 1 fire and then Apollo 7 which contained thousands of human spaceflight safety advancements and improvements and the testing of many of those advancements with the Apollo 7 flight.  A listener asked about nuclear propulsion and NERVA.  This resulted in a phone call from Dr. Dewar who continued the discussion with nuclear propulsion but advanced it to include the development cryogenic systems to support the H bomb and then these systems making their way to NASA.  John and Jim had much to say about the H bomb and space development connections so don’t miss this discussion.  By the way, Dr. Dewar is returning to The Space Show on Dec. 6.  John talked about the biomedical advancements in aviation that contributed to safer HSF. Here, he mentioned the work by Dr. John Paul Stapp and others, especially out of Holloman AFB in New Mexico.  Don’t miss this discussion or the relevant PPT slides.

In the second segment, John from Ft. Worth called to continue the discussion about the H-bomb and space connections, huge airplanes to deliver the large bombs and the later development of compact warheads which lead to the use of smaller missiles.  They also compared these advancements to the Soviet Union program of the day as the soviets used a different system for the bomb which resulted in it being smaller than the initial American weapons.  The two John’s continued talking about cryogenic development.  Dr. Jurist then advanced the discussion to the economic benefits of space development and how space has advanced the standard of living for everyone on the planet.  Some side discussion topics including space and former V.P. Spiro Agnew, space shuttles, Skylab, and bone metabolism resulting in the DEXA scan.  Dr. Doug called in to talk about baby boomers and the creation of graduate students in STEM and non-STEM fields.  He also asked if a DEXA scan could be made small enough to go to the ISS for real time measurements.  Dr. Jurist offered an easier way for those real time studies.  Several listeners asked Dr. Jurist if we could recreate this type of program today.  John said he was doubtful, especially given the IRB would likely have a total fit with self-experimentation.  He spent more time on the Apollo 1 fire, then he got questions about the opportunity cost of space development asking if we would not have had the same advancements if not more had we spent the money on programs other than space.  Don’t miss how John responded to this question.  Another listener pointed out emergency and trauma medical advancements as a result of recent wars and asked our guest if those advancements would have come about had it not been for the recent wars that helped develop these new treatment protocols.  Again, don’t miss how Dr. Jurist responded to this question.  As our program was ending, Dr. Jurist offered concluding comments that you will certainly want to hear and consider.

Please post your comments/questions on TSS blog above.  You can contact Dr. Jurist through me.

We welcomed Damian Peach, well known amateur astronomer from the UK to the show.  Visit his website for more information and to see his work, www.damianpeach.com.  During the first segment of our 90 minute program, Damian talked about his early interest in space and the definition for an amateur astronomer. We learned most are self taught as was the case with Damian, that the field was not as math intensive as a professional astronomy career and that amateur astronomers significantly contribute to the field of astronomy and work well in harmony with professional astronomers.  During this segment, listeners had many questions for our guest including asking if he had sponsors, the cost of amateur equipment, his typical viewing schedule on the South Coast of the UK where he lives and his other location, Barbados.  In fact several questions came in about viewing conditions in Barbados and the effect of weather and humidity on his viewing in that location.  Damian likes to photograph Jupiter and Saturn and the bigger outer planets.  Don’t miss the why behind this.  As you will hear and you can see on his website, he has also done lots of excellent imaging of the Moon.  I asked him about his interest in going to Mars, human spaceflight, and more, all of which he said he was interested in.  Other first segment topics included wanting to know more about his techniques, amateur spectroscopy, and amateur peer review.  Regarding his interest in Jupiter, he talked at length about the always changing Jupiter weather that he liked to document in his Jupiter photography.

 

In the second segment, he talked about the upcoming JUNO Mission to Jupiter & the need for amateur astronomers to take images and submit them to the JUNO team.  Other topics in this session included cubesats, amateur astronomy groups in Europe, the U.S. and elsewhere, plus Pluto and New Horizons.  Listeners asked about amateur solar and deep space astronomy, cosmic rays, and more.  Science fiction came up as did the movie Interstellar.  Later, Ben sent in a note while looking at Damian’s Mars images on his website and asked about color enhancing and photo touchups.  Imaging Mercury and Venus came up in the discussion as did light pollution, viewing & searching for comets & NEOs.  Near the end of the program, we talked about Ceres and the Dawn Mission from the amateur perspective.  Near the end, I asked Damian his first choice mission were he the space mission guru.  I bet you will be surprised by what he said.  Dr. Dewar asked about making space access available with space based telescopes through nuclear propulsion given the cost of launch would be so much cheaper. Don’t miss Damian’s response.  Marshall called at the end to talk about technology advancement & more.

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.”

Guest:  Dr. Donald Rapp.  We discussed using indigenous resources to facilitate HSF to Mars, then the great climate change debate based on facts not agendas.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

We welcomed back to the show Dr. Donald Rapp to discuss two important topics.  In the first segment we addressed using indigenous resources to facilitate human spaceflight to Mars and the MOXIE experiment on Mars 2020.  In the second segment, Dr. Rapp examined the climate change debate without out preconceived belief systems by an honest examination of the data.  To start our first segment, Dr. Rapp talked about the massive amounts of propellant needed for a human mission to Mars which then led us to discussing using resources on Mars to make propellant for the return to Earth.  Our guest was asked about going to Mars via the Moon and using lunar ice to make propellant for the Mars mission.  This proved to be quite a mini-discussion as Dr. Rapp was skeptical about the use of lunar resources including water ice as an assist for a manned Mars mission.  Many listeners asked him challenging questions about his position and conclusions do don’t miss this important discussion.  Later in the segment a listener asked Dr. Rapp about the potential benefits of using nuclear power and nuclear propulsion.  This too was a fascinating mini-discussion so don’t miss it, especially the call on the subject from listener Kris.  Dr. Rapp was asked about the MOXIE experiment which we talked about at length, then he was asked about the need for heavy lift rockets to Mars.  Our guest supported heavy lift which he defined as a 100-120 tons to LEO.

 

In the second segment, climate change was our main topic.  Here he talked about extreme agendas by both the climate alarmists and the climate skeptics and said a new group was emerging which he called the “lukewarmists” who actually and honestly evaluated the data without a preconceived belief system.  Dr. Rapp went through the known facts, the history of the subject, the warming periods, the CO2 levels and where on Earth warming mostly took place though there has been no warming from 1998-2015.  We talked about sunspots and climate change and the impact of El Nino and La Nina.  He also talked about global energy usage and the projected increases for the 21st century and beyond.  The increasing use of power and pollution by China and India were important factors in this discussion.  Listeners had many questions for him including many wanting a way to deal with excessive, costly and unscientific regulations that are forced on the people by politicians who don’t know the facts and have an agenda to their behavior.  No solutions were offered.  A teacher wrote in about the challenges she has teaching factual climate change to her students because parents on both sides of the issue come in and complain that the “truth” was not being taught in the class.  Dr. Rapp offered us concluding remarks around the basic idea that everything is complicated including sending humans to Mars and dealing with climate change issues.

We welcomed Sonia Van Meter to the show to discuss Mars One and the Mars 100 as Sonia was selected to be part of the Mars 100. During the first segment of our 100 minute program, Sonia was asked when she first knew she wanted to go to Mars. Though she has always been interested in space and related topics, it was not until she discovered Mars One that she became interested in going to Mars. During the early part of this discussion, Sonia puts forth why she wants to go to Mars & why she thinks it is important to go there. These themes were repeated throughout our discussion. Sonia got many questions about how difficult it might to leave family and friends plus listeners wanted to know if she was a skeptic about the Mars One mission. Sonia explained the importance of looking forward and focusing on the future, not on being skeptical. She was asked how she got her Mars information. She does due diligence on her own as well as receiving some information from Mars One. Sonia said she was in touch with many of the other Mars 100 finalists and they also due their own due diligence and discuss topics among themselves on a frequent basis. Listener questions by emailed were coming in rapidly asking everything from her backup plan if she did not go to Mars to what she would do for healthcare on the Mars One mission. Many listeners asked her about the risks including human spaceflight medical issues, launch risks, and more. She said the mission would need to be vetted by scientists and medical types and if she did not think it was safe, she would pull out of it. Other listeners wanted to know her perception of living conditions and the Martian environment. I asked if spacesuits would be used and if she did any rough camping, backpacking, etc. as a kid that might have helped her prepare her for tough living conditions on Mars. The MIT Study came up and was discussed as well as growth for the Mars One settlement coming either from Earth, the settlers, or both. She said there would be no childbirth for years as it was not safe so for the time being, the settlement would be growing by subsequent Mars One missions. Doug called to make the case for going to the Moon first. Sonia explained to him that she had no opportunities for going to the Moon though she would take them if offered. The only opportunity she had was Mars One. Sonia was looking at the picture from the vantage point of her own objectives while Doug had the big picture of lunar return and development in mind.

In the second segment, Bill from Virginia asked if Bas or other Mars One executives were planning to go on the mission to Mars. Don’t miss her answer. Todd wanted to know about a possible rescue mission and Andrew sent in a note about Mars One simulations & developing the infrastructure to live off world. I asked our guest if she had factored in launch risks & Randy in Boston asked if she had done a cost benefit analysis on the value of the mission versus the costs of it. Sonia said the educational outreach PR was a large part of the value for her. Privacy issues came up plus she was asked if Mars One went to a moon of Mars would she be disappointed. Don’t miss her answer to this question. Near the end of the show, I asked Sonia for her thoughts should American government regulations make her Mars One trip impossible. I also asked if she had considered or would consider pre-emptive surgery to have her appendix or gall bladder removed before going to Mars. Kris in Denver wanted to know if Mars one went under and the people on Mars were stranded, was it the responsibility of nations and their public sectors to attempt a rescue mission for the stranded “Martians.” Sonia was asked if she would be OK with nuclear propulsion if it shortened her transit time to Mars and then at the end, I asked her about planetary protection and the limits on landing humans on Mars. I directed her to the NASA Office of Planetary Protection for more information.

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 Henry Vanderbilt back to the program to tell us about the upcoming Space Access Society Conference to be held in Phoenix, Arizona from April 30-May 2, 2015. For information, speakers, and program agenda, see www.space-access.org. During the first segment of our 91 minute program, Henry talked about the logistics of the conference to be held at the Radisson Hotel North in Phoenix. You can register for the conference and the hotel online. Henry then highlighted many of the sessions and speakers for this year’s event. See the Space Access website, www.space-access.org. I asked him what talk or event excited him the most and he said they all excited him. He then focused on a few main speakers including Dave Masten, Jeff Greason and the COTS 2 Return to the Moon track that Dr. Doug Plata will be chairing. Details for this special track within the overall Space Access track are on the Space Access Society website. Henry highlighted the special track with Doug and his track participants, then he focused on the Town Hall Program designed to solicit new and fresh ideas for cheap access to space and space development. Before the segment ended, Charles Pooley called and we talked about New Horizons and fast, high energy deep space issues and advanced propulsion as a result of Marshal’s phone call.

In the second segment, Doug called to talk about his track but also about the superb networking opportunities at Space Access. Doug, picking up on a first segment listener email question, said that the conference was not a space settlement conference but that with affordable space access, space settlement gets much closer to reality. Henry then spoke about Henry Spencer returning to talk and along with Doug, mentioned reusability and lunar landers. Henry will talk about rocket safety, reusability and more. Advanced propulsion technology was discussed when Ft. Worth John called us, then Henry talked about EML2, more conference speakers plus the need for fuel depots. At the end, he said that the Space Access Conference supports their political activism which Henry is really good at doing during the year on very important and key issues. He cited an example from last year. Henry also said there was still room for more speakers but you need to quickly contact him to see if your topic can work for the event. You can email Henry at space.access@space-access.org.
