This will help me bring better programming to the audience. We welcomed back Dr. Jeff Bell & was at his best for blunt talk, specifically the need for a winning rational for human spaceflight (HSF). For those of you new to Dr. Bell, hold on tight for a ride that will likely be upsetting. During the first segment of our 1 hour 58 minute program, Dr. Bell started with saying he was pessimistic over the future of human spaceflight. In fact, this was an overriding theme throughout the full discussion. He said it was more than just not properly telling the story either by NASA or space advocates. He said there was no winning rational for the need or the urgency of HSF. While he was pessimistic on HSF, he was just the opposite on science, robotic, & unmanned missions which he said were doing well & in a class of their own. He also talked about the success of satellites & that part of the commercial industry. Listeners challenged him during the show. He got several emails regarding space settlement which Jeff addressed in terms of his perspective on HSF. He also nixed the idea of leaving Earth as a safety valve for when Earth might be destroyed by an incoming NEO. This led Jeff to talk about planetary defense. Tony called with an idea to keep a Martian settlement from freezing at night, a point Jeff talked about re Mars settlements. A listener asked about radiation & magnetic fields. Jeff said the atmosphere was more of a screen for Earth, again in a discussion about lunar & Martian settlements. Jeff talked about Orion & SLS, various ideas for Mars missions & the NASA asteroid mission. I asked Jeff what he was positive about & he replied the Russian space program & SpaceX with Elon. He then spoke about some of the Russian programs he follows. He was asked about space tourism & suborbital flights, then he spoke about SpaceShip2 problems, hybrid engine issues, Richard Branson & more. In the second segment, he had more to say re SpaceShip2 & Branson. Next, he was asked about space debris cleanup ideas being skeptical of them. He was also skeptical of propellant depots. He spoke about small boosters costing much more than using one large booster. Pooley called in to support everything Jeff was talking about. Dr. Bell was asked about Dream Chaser. In general, Jeff was very critical of lifting bodies & their CG problems. Listeners asked for his assessment of Inspiration Mars & Mars One which was not positive. In his closing comments, he said HSF was probably mature & needed radical new technologies to make it cheaper & feasible. I told him he should come back on the show, invite only callers & emails suggesting radically new & different technologies & he could assess the ideas. Dr. Bell agreed to do that so watch the newsletter for this upcoming program. Please post your comments/questions on TSS blog.

This will help me bring better programming to the audience. We welcomed Anthony Young to the program to discuss his book "The Saturn V F-1 Engine: Powering Apollo into History. This is an excellent book which I strongly recommend. Remember, if you buy it through the OGLF Amazon portal, Amazon makes a contribution to The Space Show. During the first segment of our two hour program, Mr. Young started out talking about the book and why he wrote it. Since our guest had also written books car engines, I asked him if there were comparisons to be made with the F-1 & the large, complex, & powerful car engines. We also talked about potential plans to rebuild and modernize the F-1 for either the SLS or as a possible engine replacement for the Air Force RD-180. Anthony did say that it would not be a rebuild of the F-1 but a complete remake of it with modern manufacturing, materials, etc. Another topic discussed was the F-1 thrust for a new engine. Marshall called to talk about fuel propellants for the F-1 and air pollution. This gave Anthony the opportunity to talk about ATK and their efforts to modernize the SRB & solid rocket propellant. Anthony suggested that we need advanced propulsion for humans to Mars to significantly reduce the transit time, not a new F-1. Michael called in & talked about SLS being needed to preserve the expertise & knowhow for making large rockets & flying them. He also spoke about some of his upcoming Space Review articles on the Code of Conduct & other subjects. He brought to our attention a YouTube video, "The Engines That Came Out Of The Cold" (www.youtube.com/watch?v=MZnYr94aa9E). Mr. Young was asked about the existence of NASA lunar programs. He mentioned several including Lunar CATALYST but suggested they were small robotic missions. He did not think there were NASA human flights planed for the Moon. Dwayne called to shed further light on NASA and lunar programs. He also spoke about the F-1 thrust for a new engine. In the second segment, John called from Ft. Worth. He spoke about technology and performance for the engine, other programs now cancelled & the logic of having stayed the course. He brought up good points on our losing our technology capability, then Anthony addressed many of the NASA KSC infrastructure changes going on to partner with the commercial industry. Doug called to talk about some of the lunar program comments, to offer a different perspective on SLS, & public/private partnerships as well as international participation. Anthony was asked for his thoughts on where our space program might be today had the Saturn V & F-1 not been cancelled. In responding to this, he talked about how complex the F-1 was & how many parts were in it. Please post your comments/questions on TSS blog above. You can reach Mr. Young through me & you can read his articles published on The Space Review. Selected by: David Livingston [ stations ], Mon, 24 Mar 2014 15:53:16 UTC

This will help me bring better programming to the audience. We welcomed Gwynne Shotwell, President & Chief Operating Officer of SpaceX back to the show for an hour discussion & Q&A from the listeners. During the first hour segment of this 72 minute program, Ms. Shotwell started out with me asking questions prior to opening the program to the listeners. I inquired about using Brownsville, TX as a spaceport, SpaceX qualification requirements & timelines to fly sensitive USAF costly spy satellites to orbit, reusability, the possible use of Falcon & Dragon for a lunar mission, and fast tracking Dragon for HSF given the problem with Russia, the Crimea, and the Ukraine. Gwynne told us about New Dragon and modifications to it and theCRS-3 Dragon contamination concerns for the upcoming launch on March 30. About 20 minutes into the discussion, I opened it up for listener emails and phone calls. I did have some audio issues with the toll free line so I apologize in advance for them but all the callers were clear and understandable as the problems concerned the toll free line ringing. Listner questions addressed launch pad modifications for larger rockets, the SpaceX Raptor, reusability, possible payload penalties with reusability, propulsive landings, and reusable launch vehicle trajectories. One listener asked our guest about possible markets for the bigger Falcon heavy lift launcher, Falcon XX. We learned that this size rocket was for human transportation to Mars. Gwynne fielded several questions about Falcon and Dragon on lunar missions. While not opposed to lunar missions, SpaceX does not want to be distracted from their primary objective which is Mars. Another listener asked about pricing and secondary payloads, the launch abort system, then I asked about SpaceX near term challenges and longer out challenges to 10-11 years from now. Our guest was asked about birthing and when SpaceX would dock with the ISS. Later in the segment there was a question about competition in the launcher industry, if SLS was viewed as competition, using a Falcon for a Europa or Titan mission, & the difference between Air Force requirements and special NASA requirements. As the segment was drawing to a close, a high school student asked about internships at SpaceX. Gwynne also talked about how valuable & important their relationship with NASA has been and how NASA has been a large part of their success. In the very short second segment, I went over the upcoming Space Show schedule and let the audience know several dates when there would be no programming due to Easter & my personal schedule.

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomed Jeff Smith to the program to discuss the recent Space Expedition Corp program held at the Griffith Observatory in Los Angeles. We initially learned of this event when Doug Messier was recent a guest on the program and since Jeff was going to be in Los Angeles, he decided to attend the event while in Los Angeles. During the first segment of our 91 minute, Jeff introduced us to Space Expedition Corp (www.spacexc.com) which is a Netherlands based space service company wanting to sell & service flights on the XCOR Lynx suborbital vehicle in Curacao. Jeff described the audience attending the event, spoke about the qualifications, expertise, and knowledge regarding the Space Expedition Corp's (SXC) speaker at the event and others in the company. Listeners asked many questions, including environmental questions regarding rocket pollution in the atmosphere. Jeff said this was discussed at the event. Another listener asked about ITAR given XCOR was working with a company in the Netherlands. Both Jeff and then later another listener, Carl, responded and explained the ITAR situation vis a vis XCOR. Jeff also talked about opportunities in aerospace as a result of many leaving the Air Force or other services after their 20 years. Another observation Jeff offered was that he thought more companies were interested in marketing space, not doing space. Jeff was asked if SXC planned Lynx flights at locations other than Curacao. Listener Carl responded that XCOR was planning flights in the States and elsewhere but it was not clear if SXC would be operating in locations other than Curacao. In the second segment, I asked Jeff for his thoughts on the NewSpace industry in general, plus the emerging suborbital industry. Here, Jeff had lots to say, including some concern for market issues and the low barrier to entry for parts of the industry. Betsy in Tulsa asked him what inspired his interest in NewSpace and like many of us, Jeff was addicted to space everything at a very early age, chose to get an education in a related field and follow a career in aerospace. He also wanted to follow the entrepreneurial side of things through NewSpace. He said NewSpace seems to be more ideologically driven than traditional aerospace. We talked about star gazing in Tucson, the Planetary Science Institute plan for telescopes on a Lynx, & the ability of students, especially at the high school level, to do science experiments that were space related through cubesats and more. Please post your comments/questions on TSS blog. Jeff can be contacted through me. Selected by: David Livingston [ stations ], Wed, 19 Mar 2014 16:15:27 UTC

This will help me bring better programming to the audience. We welcomed Lee Hutchinson to the program to discuss his recent article, "The audacious rescue plan that might have saved space shuttle Columbia" which you can read at http://arstechnica.com/science/2014/02/the-audacious-rescue-plan-that-might-have-saved-space-shuttle-columbia. Note that Mr. Hutchinson said he found the possible rescue plan spelled out in the CAIB report in seldom discussed Appendix D13 of the report. In questioning Lee, we also learned that the plan did not exist real time with Columbia but was actually requested as part of the Columbia Accident Investigation Board's work. In the first segment of our 1 hour 28 minute program, our guest told us why he wrote the article and how he noticed the possible rescue plan back when he was tasked with reviewing the CAIB Report. During this segment, our guest described all parts of the plan and we discussed the likelihood of it having worked had it been implemented. Lee also discussed probable & significant timing issues with parts of the rescue plan making it unlikely to have been implemented had it been a real time plan under consideration. It was dependent upon too many things happening precisely on time and schedule, something that was not always possible with shuttle launches. Lee also went over the specific crew training issues that would have been required, plus issues in using EVA suits and getting them to and from Columbia for the astronauts to use. Listeners asked many questions including questions about NASA management at the time, risk averseness, & the NASA culture. Lee was asked about the comments & feedback he received from writing his article. As the segment ended, Mr. Hutchinson discussed plane change maneuvers and the significance of the orbital inclination of Columbia and the ISS. In the second segment, a Cleveland listener ask for Lee's thoughts on SLS-Orion. Lee & I talked about this & the NASA culture plus the need for heavy lift assuming there are missions for it. He was asked if the shuttle could fly without pilots, then we went back to SLS. He also told us about his interest in the redesign of the F1 engine. You can read his articles on the F1 here: http://arstechnica.com/science/2013/04/how-nasa-brought-the-monstrous-f-1-moon-rocket-back-to-life; http://arstechnica.com/science/2013/04/new-f-1b-rocket-engine-upgrades-apollo-era-deisgn-with-1-8m-lbs-of-thrust. Lee received several email questions regarding the foam strike on Columbia & foam modification efforts. He was also asked about the shuttle repair kit which was carried on subsequent shuttle flights. Benny asked if a 3D printer on board could have made the materials to repair the Columbia damage. Please post your comments/questions on TSS Blog above.

There was an audio issue with this program so listen carefully so you don't miss anything. During the first segment of our 90 minute program, Robert went over some of the basics such as the Coriolis effect, the gravity gradient, tethers, centrifuges, the vestibular effect, and more. He also went over linear acceleration, spin rates, Russian experiments, issues facing space tourists, and spinning a Dragon capsule. Robert has written many articles on artificial gravity which can be found at www.science20.com/space. One such article was discussed yesterday. See www.science20.com/robert_inventor/blog/ingeious_idea_soyuz_crew_tether_spin_way_iss_artificial_gravity_almost_no_extra_fuel-131278. Also, check out www.science20.com/print/131279; www.science20.com/print/131278 & www.science20.com/print/129424. In our second segment, Robert talked about both Inspiration Mars and Mars One as it relates to spinning to create artificial gravity, the number of revolutions per minute, simulate programs, and his favorite, a 2-3 year precursor mission at Earth L2. He wants the mission designed to be a comprehensive test bed for artificial gravity. Later in the segment while discussing Mars, he suggested we orbit Mars and not land on the planet. Listen to his reasoning for this type of human Mars mission. For one thing, he said its much safer to be in orbit. We then focused on the possibility of microbial life on Mars, we talked about the Viking Labeled Release experiments. Robert was asked a question about the sleeping centrifuge (you sleep horizontal as one does on Earth). Partial gravity was discussed as well. Robert said many times that we must find out what is going on with Mars. He mentioned the Phoenix mission which Mars One is planning to copy to some degree with its robotic mission to Mars in 2018. Please post your comments/questions on TSS blog. You can reach Robert via his articles or through me. Selected by: David Livingston [ stations ], Sat, 15 Mar 2014 17:30:13 UTC
