We welcomes Randa and Rod Milliron back for this 1 hour 36 minute discussion about their company, Interorbital Systems (IOS), rocket engine development and testing, and much more. Visit their website at www.interorbital.com for more information and details of topics discussed today. We started out by getting details about the IOS static engine test in Oct. 2012. Our guests talked about the test and described their engine and the Neptune modular launch system. Rod talked about using hypergolic propellants and why they chose to do so, plus our guests went over the capability of the Neptune rocket depending on how many modules and stages were used. They also talked about adding a stage for the lunar lander as they are a GLXP participant. We talked about the GLXP, getting secondary payload rides to the Moon or using a dedicated launcher such as the Neptune. Our guests described their plans for doing a sea launch and why, probably in the Pacific Ocean near Hawaii. They also talked about having spaceport launching capabilities as well. Listeners asked about demo flights and time lines, plus suborbital test flights. Another listener asked about the plans for Olav Zipser to jump from a rocket in light of the Red Bull success. Wes from Tampa emailed in about suborbital flights offering a space view for sensor testing, retrieving payloads, & testing low gravity manufacturing/3D printing. IOS suborbital flights are their test flights. Our guests had much to say about these matters, especially retrievable payloads. Blair emailed in about IOS due diligence, their launch track record, and their consumer sales. We then talked about the IOS personal satellite TubeSat and CubeSat kits. Wes called in to talk about his positive experiences given he has purchased one of the kits. I also asked Wes about his due diligence on IOS before buying the kit. Listen to how our guests and Wes responded to this line of questioning. In the second segment, I asked about engine test regulations & required permits for testing at Mojave. Randa and Rod mentioned complying with ITAR because they have foreign sales of the personal satellite kits. They also talked about a 4H group on the Utah Colorado border building a personal satellite and the educational outreach this involves with the Ute Native Americans and others. The Millirons were asked about their being considered fringe by some in the space community. Note what they said about this and about attending space conferences. A question came in as to why they were not using a hybrid engine. Rod had lots to say about hybrids, don't miss his comments. Our discussion concluded with a summary of their forthcoming rocket plans and development program. Please post your comments/questions on The Space Show blog. You can reach our guests through their website or through me at drspace@thespaceshow.com. Selected by: David Livingston [ stations ], Sat, 23 Feb 2013 17:26:04 UTC

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We started our one hour fifty-one minute Open Lines discussion by my throwing out some suggested topics which included recent USA Today polls on human spaceflight to Mars and informed consent using the recent Carnival Cruise Line cruise from hell as a possible indicator of what may happen in the space tourism industry. Dave, our first caller, talked about the new efforts to create NTRs and have nuclear propulsion using tungsten as the fuel base. Dave had lots to say about the tungsten as well as traditional fuels. I next read a listener email about an NCIS Los Angeles 2011 episode about satellite sale to a foreign party and ITAR,. Next, we talked about another listener email calling our attention the SpaceWorks Nanosatellite Market Report, and then up next was the CNN interview with Bill Nye and the CNN anchor asking Bill if global warming was causing the NEOs and events like the Russian meteorite. Thanks to Tim for sending in the URL for the interview which you can see and hear at www.youtube.com/watch?v=ObU7awpJctQ. In our second segment, Pooley called in to support my informed consent and Carnival Cruise Line comments plus he again told us why he did not think the space tourism industry would be successful. Charles also talked about the Russian meteorite and the need for a dedicated cubesat or nanosat launcher over and above flying small sats as secondary payloads. In addition, we talked about the Google Lunar XPrize and the absence of launch contracts for the ride to the Moon. Tim called to talk about the nanosat launch industry, we talked about the upcoming Virgin Galactic1 small satellite launchers and deep space radiation and HSF. The dedicated small sat launcher reminded me of an Oct. 13, 2008 Jurist Space Review article proposing a university consortium for such a launch system and the condemnation he got for his proposal. Dr. Jurist called in to talk about his proposal and the response. You can read his 2008 Space Review article here: www.thespacereview.com/article/1228/1. I also asked Dr. Jurist about Tim's radiation comments and he explained this particular radiation issue to us. He also said there was a real lack of valid data points so much of what Tim, John and I were talking about was simply an unknown or extrapolated from data pools that may be quite different from those at the lower end of exposure. In discussing this subject, Dr. Jurist talked about American radiation standards, astronauts as radiation workers, and the European standards. At the end of the program, Tim called to talk about the Carnival Cruise Line incident and informed consent. Tim suggested tort reform with caps but also put forth a novel behavioral theory and I told him I would absolutely go on the five day cruise from hell to earn a million dollars! Please post your comments/questions on The Space Show blog. You can email any of the participants in this program through me at drspace@thespaceshow.com.

Dr. John Hunter, Monday, 2-18-13 (44.10MB; download) --
Guest: Dr. John Hunter. Topics: Hydrogen gas gun technology and capability, microwave propulsion for delivering cargo. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed back Dr. John Hunter for a fresh look at hydrogen gas gun propulsion technology and capability, microwave propulsion for delivering propellant and delicate cargo, cubesat launchers, and more. During the first segment of our 85 minute program, Dr. Hunter briefly explained his departure from QuickLaunch and the viability of impulse launch with the hydrogen gas gun. He explained how the hydrogen gas gun works which as you will hear is very simple. Dr. Hunter say that with the gas gun, there could be very high payload fractions into the 20's. Our guest was asked about total costs for the hydrogen gas gun which he referred to as installed costs. Listeners asked him to describe the physical characteristics of the gun and we talked about how many times it could be used without needing refurbishing of some kind. Dr. Hunter also talked about the high pressures and we compared the gun to the old U.S. Navy battleship 18 inch gun from the WWII era. A listener asked if the gun would make a good weapon. The answer was no. John was asked where the gun might be located and talked about Adak & Kodiak, Alaska plus other possible sites in the Lower 48. Listeners then asked if the Alaskan heavier cold air was a factor in using the gun. We learned that the differences between cold air and warm air were minor. In our second segment, Dr. Hunter introduced us to microwave propulsion launch. He spent some time describing how microwave launch would work and even talked about using consumer quality magnetrons from microwave ovens. In response to listener questions, he talked about demo launches and a Cal Tech student's PhD thesis on the subject. Later in the segment, our guest was asked about using an impulse launch system as a cubesat launcher given the rise in popularity along with growing demand for cubesats. Our last discussion topic was the use of Kickstarter for funding emerging and startup space projects. Dr. Hunter said it offered real possibilities and advantages for regular people to participate in space companies and projects, but he also issued a warning for people to be alert to not be taken given the lack of oversight with crowd sourcing funding projects in general. Please post your comments/questions on The Space Show blog. You can contact Dr. Hunter through me at drspace@thespaceshow.com.

Dr. Sean Casey, Tuesday, 2-12-13 (49.82MB; download) -- Guest: Dr. Sean Casey. Topics: Space Entrepreneurism, Silicon Valley, space startups, Silicon Valley Space Center events, programs, & objectives. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use. We do not permit the commercial use of Space Show programs or any part thereof, nor do we permit editing, YouTube clips, or clips placed on other private channels & websites. Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed back Dr. Sean Casey, co-founder of the Silicon Valley Space Center business accelerator (http://svsc.org). You can "like" them on Facebook at www.facebook.com/pages/Silicon-Valley-Space-Center/139916589409748. The SVSC can also be found on LinkedIn. While hour 2 hour 40 minute program was in two segments, this summary will be in one part as our themes and topics went back and forth in the same area throughout the discussion. Dr. Casey started with a summary of 2012 activities and events for the Silicon Valley Space Center (SVSC). During our discussion, Dr. Casey talked about, mentioned, and listed many space entrepreneurial startups and businesses, far to many to list or mention individually. He also outlined coming events for the SVSC which are available to the public and will be online for those unable to attend in person. Responding to listener questions, he cited company example after example of space startups and we even talked about Northern California, San Francisco, and Silicon Valley being the center of this effort. Upon listeners questioning him on the subject, Sean suggested additional startup space efforts in other parts of the company. While Silicon Valley does not have a lock on this new industrial development, as you will hear, startups and space entrepreneurism are developing in centers across the country. We also talked about venture capitalist ROI expectations over five years coming in around 30%. We discussed the hockey stick graph and what this means for space entrepreneurs. Sean spent time on the SVSC website and Facebook page going through the coming 2013 events and programs. Doug called in with a question about track records for startups and investors. In his response, Dr. Casey talked about the various business incubators now in place to mentor and help space entrepreneurs, even non-profits. He suggested how you might find a reputable business incubator in your own city or area though one could probably work with one of the organizations Sean mentioned, even if you are outside California. Another issue that came up was lobbying members of congress and state representatives on space policy. Here, we talked about California and I again shared my experiences with Sacramento and California Space Day over the last six or seven years. Dr. Casey addressed the uphill battle with gaining more political support for all aspects of the space industry, especially in California. Dr. Casey provided us with one of the most comprehensive space startup and entrepreneurial programs heard on The Space Show. Please post your comments/questions on The Space Show blog mentioned above. You can reach Dr. Casey through me or directly at sean.casey@siliconvalleyspacecenter.org.

Dr. James (Jim) Wertz (51.31MB; download) -- Guest: Dr. James (Jim) Wertz: Topics: Methods for dramatically reducing space mission costs, schedules, & launches. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed Dr. Jim Wertz, President of Microcosm, back to the show to discuss various methods & tools for reducing total space mission costs. Our guest talked about successful programs and tools that have so far contributed to total mission cost reduction. In the first segment of our 1 hour 33 minute program, Dr. Wertz started by defining what he meant by reinventing space. He said this refers to a dramatic reduction in total space mission costs by a factor of 2::10 for schedule related reductions and 2-5 times for space access related costs. Early on he was asked about reducing costs by increasing the launch rate, a common argument heard in various sectors of the space industry. His response might surprise you. Dr. Wertz cited examples to support his comments, specifically Surrey Satellite in the UK (SSTL) as they have been reducing costs successfully for 25 years. He said modern technology must be used. He also pointed us to his Reinventing Space Project with the USC Astronautics Department. Also, he pointed us to these websites for more information, www.smad.com/ie/ieframessr2.html and www.smad.com/ReinventingSpace.html.

Dr. William (Bill) Rowe, Sunday, 2-10-13 (69.52MB; download) -- Guest: Dr. William (Bill) Rowe. Topics: Apollo astronauts cardiac & medical issues. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use. We do not permit the commercial use of Space Show programs or any part thereof, nor do we permit editing, YouTube clips, or clips placed on other private channels & websites. Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed Dr. Rowe back to the program to discuss his latest findings regarding four Apollo astronauts, lunar dust, microgravity, and cardiac conditions. His work is presented on his website so do check it out, www.femsinspace.com. Dr. Rowe's latest findings came from his research using the Freedom of Information Act to get medical data from NASA after the recent passing of Neil Armstrong. During our first segment, Bill explained what he found, what specific blood pressure and other information strongly suggests, and his comparison of the Armstrong data with that of several other Apollo astronauts per available data. He also brought our attention to the problem independent researchers have in getting Apollo information and medical stats from NASA. Bill used stress test blood pressure numbers and other medical information from the astronauts in question to illustrate his points and to back up his conclusions. Most of our first segment was devoted to Dr. Rowe putting forth the information and his conclusions. Bill took several email questions and listener calls, often wanting more information than he could provide because the reality is that there is an absence of additional information or relevant studies suggested. One listener was asked if the ISS astronauts evidenced similar cardiac problems. Dr. Rowe was unable to answer that question due to the absence of information. In the second segment of this 2 hour 20 minute program, Dr. Rowe connected problems of lunar dust with urban pollution, suggesting microgravity studies that would benefit millions on Earth given how widespread the problem of urban pollution is on the planet. One of the studies he proposed would use 30 female rats subjects to different calcium/magnesium rations on the ISS for six months. Bill spent time in this segment explaining the importance of the calcium/magnesium ratio and what this means in space and for us back here on Earth, hence the rat study. Dr. Rowe also talked about the difficulty of having a quality exercise RX for microgravity. A listener asked about studies related to the Mt. St. Helens eruption several years ago re dust exposure. Near the end of our discussion, Bill talked about their being no hurry to go to Mars, suggested many of the near term human spaceflight missions such as one way trips to Mars won't happen for a long time because the human issues will not be resolved in the near term. He also advocated the Moon first. We talked about artificial gravity and I mentioned what other human factor gusts have said on air in that artificial gravity may not be the same as 1g here on Earth and may prove to not be a solution. Listeners did not like hearing that as they kept saying there would be an engineering solution to the microgravity issues. Listener disagreements about artificial gravity not being the same as earth gravity continued long after the program ended. If you have comments/questions, please post them on The Space Show blog above. You can contact Dr. Rowe through his website or through me.
