We welcomed back to Hotel Mars Dr. Haym Benaroya from Rutgers University. Dr. Benaroya discussed the NASA LADEE mission, lunar dust issues, the lunar surface, the importance our astronauts returning to the Moon and the Lunar Dust Experiment which so far has proven to be inconclusive regarding the questions it was to solve. Dr. Benaroya went over the toxic and corrosive nature of lunar dust to both humans and equipment, had similar things to say about Martian dust, and talked about how important it is for us to go back to the Moon. He also made the point that we should have a permanent settlement on the Moon and not just use it as a way station stepping stone to Mars, abandoning it again once we are on Mars. The three of us discussed the LADEE project in detail (as much detail as we could in this short segment). We also talked about its end which should come April 21 by crashing into the far side of the Moon.

We welcomed John Powell back to the show for updates and news with JP Aerospace. For more information, visit http://www.jpaerospace.com. Be sure to click on the Blog button at the top for even more information.  During the first segment of our 1 hour 32 minute discussion, John updated us with an overview of JP Aerospace. He has 160 missions to date & now flies PongSat missions with up to 2,000 PongSats on the flight.  I asked him how the students prepared their experiments using a ping pong ball.  We learned that the balloon typically climbs at 1,000′ per minute for a 110 minute flight to the designated altitude.  The entire trip including the landing is about 2.5 hours.  John also described the PongSat kit and all the benefits the student gets, plus he explained to us that his commercial projects, of which there are many, goes pays for the PongSats which are always free to the students.  This is his 10th year of doing PongSats but just before our break, I was surprised to hear that John has been working JP Aerospace for 37 years, starting when he was a teenager getting NASA contracts!  I next asked him for an update on his Airship To Orbit (ATO) plans.  John spent some time talking about ATO, including responding to listener questions about the likely impossibility of an airship being able to go to orbit.  This is debated in the second segment with John from Ft. Worth.  Back to our initial segment, he talked about making equipment for testing such as the Shock tube which he hoped to get up to Mach 4 in testing.  We talked about manned flight for JP Aerospace, then John told us about the submarine he was designing for use off Monterrey.  He had much to say about the sub, including the fact that its life support systems are the same as those in the ATO.  John spent some time explaining and describing the sub and outlining the mission for it.  John talked about using propellers to 90,000′, he talked about funding issues, and his volunteer labor force.  Before the break, we talked about his use of Kickstarter and his current campaign for September PongSats.

In the second segment, John spoke at length about his commercial projects and in specific the Corral Hamburger ad from Columbia (he said you could find the commercial on YouTube & he provided the search term for those interested).  He told another funny story about a live radio interview in Spain that went across Europe.  Listen for the punchline.  John from Ft. Worth called in and said he was taken back so to speak by the ATO plans which he thought were potentially possible though not possible in the way he understood physics.  The two John’s had a great discussion about this.  John Powell cited many examples of very high altitude balloons already having done some of the things he is working on doing with ATO.  Charles Pooley called next and said he still did not think ATO would work but did not revive his classic debate/argument with John on the subject.  Charles made a point of saying how impressed he was with JP success, programming and meetings its goals and missions.  He also applauded John for his being such a gentleman in their sometimes heated debate exchanges.  When asked about JP Aerospace around the world, John gave a shout out to those he knows in Poland.  For Pearls of Wisdom, John offered us “You Really Can Do This!”

Please post comments/questions on TSS blog.  You can reach John through his website or through me.

We welcomed Brett Stroozas to the program to discuss the new space burial company, Elysium (http://elysiumspace.com).  During the first segment of our 1 hour 29 minute program, Brett introduced us to the concept of space burial and in particular the new start-up, Elysium Space Burial.  He went over their services and their marketing to both customers in the U.S. as well as Japan where cremation is the common thing.  He gave us some interesting funeral industry statistics for both the U.S. and Japan and we learned that they have a Japanese language website, http://jp.elysiumspace.com.  We talked about their launch services which he said would likely be with SpaceX or Orbital but in any event they only plan to use a U.S. launcher. Also, they do not at this time have plans for suborbital launches, only orbital launches and from the established launch sites.  We talked about their expansion plans to BLEO services and learned of their mobile app which you can get from their website for Apple and Droid products.  The company has seven employees, some of which are part time.

In the second segment, I asked Brett how his company differed from the competition.  He talked about the personalized services they provide plus their intended use of dedicated spacecraft.  He also talked about the media and PR received by the firm in their first year of operations.  Listeners asked for his process when working with a completed kit, and if their memorial services were non-denominational which they are.  Blair emailed asking about their plans to use smaller launchers such as Microlaunchers. Brett said not yet but possibly down the road.  Alex asked about using government launches over private mission launches.  Others wanted to know more about their future plans and what countries they had their eyes as future markets.  India was mentioned as one such company.  When asked for their 5-7 year plan, Brett spoke about driving the costs down and launching 5-7 memorial flights per year.  Near the end, a listener asked about green funerals and Pooley emails us asking about their plans for a fast decaying LEO.  Also in this segment and in the conclusion, Brett offered a special deal for Space Show listeners so don’t miss it.

Please put comments/questions on The Space Show blog above.  You can contact Brett Stroozas through his company website, his personal website (www.stroozas.com) or me.

Today’s Open Lines discussion took place over a few segments and for about 1 hour 45 minutes.  Our Open Lines discussion started with my providing scheduling announcements as there will be no live shows the week of April 21 due to  medical issues I need to address.  Rather than play specific OLDIE programs which I usually do in the absence of a live show, I suggested that listeners go through the archives and listen to an archived show or two of their choice, compare what you heard on the archived show to similar issues in space today, then call our next special Open Lines show which will probably be Sunday, April 27 and share your thoughts and perspectives with us.  For this Open Lines program,  I also suggested a few discussion topics including Russia’s Putin saying “We are coming to the Moon FOREVER” as reported in the MailOnline on April 11, 2014.  You can read the article I discussed on the show at http://www.dailymail.co.uk/news/article-2602291/We-coming-Moon-FOREVER-Russia-sets-plans-conquer-colonise-space-including-permanent-manned-moon-base.html.  It reported Russia wanted to go to the Moon, colonize it and stay there as Russia was viewing the Moon as its own permanent colony along with similar colonies it wants to establish on Mars and asteroids.  Putin also mentioned Russia was in a race to the Moon.  Next, we fielded a few email listener questions, then John from Ft. Worth called the program to discuss an H2 documentary he saw on UFOs, “I know What I Saw.”  John talked about the documentary and other items for most of the balance of our first segment. His discussion topics included various presidential statements to Air Force and other official statements to noted UFO/ET incidents that have been reported around the world. While this is not a usual Space Show topic, it does come up from time to time.  I’ve not seen the documentary John referenced but if you want to see it, do a Google search for “I Know What I Saw” and you will find it on YouTube.  I’ll probably watch it at some point but in reading the comments about it, the reviews are definitely mixed. John also talked about the upcoming SpaceX Falcon 9 launch and its reusability plans. He asked some thoughtful technical questions about reusability but I was unable to answer them. I was hoping a listener would call in with answers as I know many who listen to The Space Show follow the Falcon 9 and reusability in great detail but they did not call in today. For those of you listening on archives, if you would like to respond to John’s comments and questions, please do so on The Space Show blog.

In our second segment, Jan emailed in asking if I would consider working with substitute hosts when I was not available for the show, similar to what happens on other talk shows when the host is not available.  In general, I am open to that but running The Space Show is very equipment intensive and I use a home studio so as I told Jan, I don’t have a clue how to work with substitute or guest hosts from the logistical point of view. I told her I was open to suggestions which I am.  Earlier, I read a PR piece about the total lunar eclipse which should be seen in the Southwest the night of the 14th and the early morning of the 15th.  Anthony sent in a note correcting the times I put out as I read the PR announcement wrong.  If anyone sees it, let us know what you thought of it on the next Open Lines show.  John from Ft. Worth called back in this segment to talk about possibilities for the Russian lunar program mentioned in the article I brought up in the first segment.  He talked about the lack of interest for doing lunar activities in the U.S. and the reason for doing it is still largely national prestige.  A listener sent in an interesting question about differences in commercial space, private space, & entrepreneurial space.  Joe sent in an email commenting “what is going to happen to the space industry when Elon and SpaceX successfully land a fly-back booster?”  We discussed the premise of Joe’s question and as I said, the industry is already seeing & feeling the impact of SpaceX Falcon 9 in the market place so if they prove out reusability and its potential cost saving features, I suspect the industry will be forced to make some significant changes and adjustments in their respective business models.

We welcomed back Dr. Clay Moltz to the show to discuss his new book “Crowded Orbits: Conflict and Cooperation in Space.”  Please remember to buy this book through the OGLF/The Space Show Amazon portal so Amazon will contribute to The Space Show.  Our Amazon instructions are in every archive summary and on each Space Show blog entry.  During the first segment of our 90 minute discussion, Dr. Moltz told us why he wrote the book which was to address orbital crowding, possible conflict in space and to bring these issues and others to the attention of the general public as space impacts everyone everyday.  A major topic for our discussion was space debris.  Using this field as an example, Dr. Moltz  made a very strong case for rules of the road, space traffic control issues, and responsible behavior by both governments and the private sector.  We talked about entrepreneurs and private groups resisting a more regulated environment and he made the case for the need for cooperation to avoid conflicts.  Early in his book, he outlined three significant points of view regarding the debate over space policy, ranging from conflict & the military use of space was inevitable so prepare for it to avoiding problems by piecemeal global engagement to increasing the use of international space projects through international governance.  Dr. Moltz received many email questions challenging a regulated environment and the need for more controls on space businesses and operations.  We talked about the cubesat technology and growth of the industry, the lack of registration, & as the industry grows, possible crowding problems.  We also discussed the U.N. treaties that seem to cover what we were talking about so why the need for more agreements & regulations?

In our second segment, we continued our human spaceflight discussion from the end of the first segment, plus we looked at space in other countries.  We mostly focused on China, India, Iran, and North Korea among others.  We talked about large scale industries that may develop over time such as SSP.  GPS was an example, then a listener asked about cyberwarfare & the impact on space policy.  Toward the end of the program, I asked about space interest among students at the Naval Postgraduate School. Students are very interested space and the subjects discussed in Clay’s book and on today’s show.

Please post your comments/questions on TSS blog.  You can reach Dr. Moltz through me.

We welcomed Marcia Smith of www.spacepolicyonline.com to the segment to discuss the National Research Council’s sanctions against Russia for their behavior in the Crimea/Ukraine region. We talked about the sanctions applicable to NASA, Roscosmos, exemptions from the sanctions of which there are several, the ISS, NASAs budget, the U.S. Congress and the continued funding, and a priority for SLS-Orion. We talked about Susan Eisenhower, a long time NASA advisor, siding with Senator Bill Nelson in thinking the sanctions may backfire on NASA & the U.S. because of the lack of scientific exchanges. Much more on this topic was discussed in this 11.5 minute segment.

We welcomed Bob Zimmerman back to the program for a discussion on a variety of space new and policy topics.  During our first segment of our 2 hour 5 minute show, we talked about the U.S. sanctions against Russia for their behavior in the Crimea/Ukrainian region and the instructions to NASA to halt all activity with Russia on space issues other than what is related to the ISS.  As Bob pointed out about 98% of space activity with Russia is ISS oriented so Bob said the sanctions did not amount to much.  He then talked policy, the idea that Russia wants its own space station and breaking the ISS agreement. He said nations break agreements like this all the time and cited our pulling of the EXOMARS agreements with Europe as an example.  He then   told us about the PLATO multi optical telescope being built in Europe for looking at exoplanets.  Next, listeners wanted to talk with him about the upcoming Falcon 9 launch and reusability.  Bob had much to say on the launch, the delay, and first stage reusability.  Philip emailed in from New Brunswick about the Russians largely sticking to themselves on station.  Bob spoke to cultural difference with the Russians, language issues, and said that they tended to their own experiments as we do our experiments.  He also said the Russians need to keep the ISS going and need us to stay with it.  Virgin Galactic was discussed and Bob went over some the test, engine, and personnel changes in recent times.  A listener emailed in about a Fox News Show over the past few weeks in which space made up part of the show.  The Fox News panel seemed to be traditional in nature and felt our space program was a mess and declining.  Bob spoke to his usual position in that he does not want any government space program.  Tony called from Seattle to talk more about reusability & the problems with the SpaceX first effort on this on a prior launch.

In the second segment, we mentioned the role of satellites in looking for Flight 370 and Bob talked about rescuing people and such programs in general.  We asked for suggestions for new space topics for discussion and Bob himself suggested underground oceans on Enceladus & LADEE’s results from the Moon for lunar dust experiments.  We talked about the emerging cubesat industry, Dream Chaser, then near the end of the show, I asked Bob for an update on the White Nose bat fungus problem.  We talked about the possibility of space being a topic in the 2014 congressional elections and Bob spent lots of time telling us all why SLS was no good.  Visit his website, http://www.behindtheblack.com.

We welcomed Randa and Rod Milliron back to the program to discuss their successful March 29, 2014 Common Propulsion Module Test Vehicle launch plus updates on the overall Interorbital Systems (IOS) s progress.

In our fist segment of this 91 minute program, we mainly talked about their recent launch which Randa and Rod took us through step by step.  Lots of questions came in via email by listeners and later on by phone calls.  Some of the questions focused on the PR given the John Frusicante’s (Red Hot Chili Peppers) album ENCLOSURE (The Record Collection, Malibu) payload which was incorrectly described by the non-space industry media.  We also talked about IOS getting a Class 3 waiver for the launch & what that process involved.  Rod took us through technical and design aspects for the rocket and we also talked about the larger Neptune Modular Rocket System that the company is developing for orbital spaceflight.  Also of interest to listeners were the IOS TubeSat and CubeSat do it yourself kits which include a launch when the kit is completed.  As we learned, IOS is rapidly filling up their third planned launch for these kits.  Another point of interest was their upcoming launch for this summer which will be a guided launch for the first time.  Both Randa and Rod talked about being vertically integrated and making and doing all the parts and engineering in house.  One email listener asked for their plans to go suborbital and then orbital. Another listener inquired about the do it yourself satellite kits pricing & ease of building.  Before the segment ended, we talked about the IOS plans for ocean launch.  Neb called in from Bosnia to talk about the IOS success throughout Europe and the positive impact of the musical payload.

In the second segment, we talked about IOS ITAR requirements, the number of payloads per rocket, the ongoing plans for a lunar mission, nuclear propulsion, and their guidance system.  Neb call again from Bosnia to talk about how IOS was inspiring people around the world.  Randa gave us an update on the plans for Olav Zipser to skydive from a rocket, then Doug emailed in to inquire about how the diameter of the common propulsion module was determined.  Randa & Rod also talked about their future plans for visiting Venus. Don’t miss this discussion.

We welcomed Dr. Behrokh Khoshnevis to the program to discuss 3D Printing and Contour Crafting which Dr. Khoshnevis invented.  For more information, visit http://www.contourcrafting.org, http://www.craft-usc.com, and http://www.bkhoshnevis.com.  In our first segment of our 1 hour 45 minute discussion, Professor Khoshnevis provided us with an overview of 3D printing, its history, strengths and weaknesses.  He also took us through the three main methods of fabrication and their subsets.  We talked about state of the art manufacturing processes and several times during our discussion he said 3D printing would never replace modern manufacturing which would always develop along the cutting edge in advance of 3D printing techniques, processes, and speed.  He talked about the materials being used for the printing and the strengths and weaknesses of them.  We began talking about 3D printing in aerospace and he talked specifically about “layering.”  During this segment, he told us how he started looking for new processes for printing large structures which is what contour crafting is so good at doing.  He explained contour crafting in construction and he identified multiple specific uses for it.  Since he had already talked about how slow the process was with 3D printing, he made a point of saying that contour crafting could be hundreds of time faster than just regular 3D printing.  In talking about aerospace, he explained why logistics can be a problem. Later in the segment, we talked about the significant power needs even in space, plus the high use of water.  Because of the water, he told us about substitute methods that made it possible to not use water.  He said meaningful structures could be made such as habs.  He fielded several listener questions, including some that asked about 3D printing being a magic solution, especially for space applications.

In the second segment, our guest was asked about the impact of microgravity and radiation on contour crafting and 3D printing.  Doug called in and talked about inflatable structures rather than construction of structures.  Our guest offered Doug important observations about the inflatable structures.  We also asked about the high demand for water by these printing processes.  Behrokh said that water usage might be a problem but by using sulfur and insitu resources, there would be alternatives to water.  A listener asked him if a spacesuit could be printed.  Our guest said not likely giving the reasons for that thinking.  We talked about 3D printing of food, medical supplies & medicines.  As we were ending, I asked the professor for the level of interest his students show in the contour crafting and 3D printing fields.  His response might surprise you.

We welcomed back Dwight Steven-Boniecki to discuss his latest book, “Live TV From Orbit” which focuses on how television was transmitted from Skylab, ASTP, Shuttle and in general from orbital space.  In segment one of our 1 hour 31 minute program, Dwight provided us with an overview of the book which is a sequent to his earlier best-seller, “Live TV From The Moon.”  Remember, if you buy Dwight’s books through the One Giant Leap Amazon portal (instructions are above, on the blog, and on TSS website as well as the OGLF website), Amazon makes a contribution to The Space Show/OGLF.  Among our discussion topics was Skylab and the Apollo-Soyuz Test Project (ASTP).  Dwight took us through the challenges of bring us live TV from these orbiting missions.  He went over the challenges and at one point, he said that both were much harder than doing TV from the Moon.  Dwight talked about the declining public interest in these missions, camera and technical modifications, and what was involved in bringing us color TV from orbit.  He received questions about Skylab’s return to Earth, the differences between NASA and the Soviet space agency and program, especially over being open & transparent.

In the second segment, we talked about the ground stations needed to receive the TV signal, the role of West Germany, the video cameras, and the use of pre-recorded video for broadcast back to Earth and on TV later rather than real time.  Regarding Skylab, Dwight told us about having a rescue vehicle available and he responded to questions about solar activity that played a role in Skylab’s early return to Earth.  Dwight was asked several questions about the ISS and our current program with listeners wanting to know was carried forward to the current programs & what evolved from those of the past.  Regarding Shuttle, he talked about a noticeable attitude shift within NASA around risk averseness & other issues. We also talked about the CD that comes with the book as it has unique videos of the missions on it.
