We welcomed back Dan Adamo to the show for this 2 hour 36 minute comprehensive discussion regarding HSF to Mars, the Second Mars Affordability and Sustainability Workshop report and much more.  During the first segment of our program, Dan started out by telling us the process used to engage him reviewing said report and writing his critique of it which is on The Space Show blog (https://thespaceshow.wordpress.com). Topics discussed in this segment included the use of Low Latency Telepresence (LLT) as compared to High Latency Telepresence (HLT), the absence of human factors and aerospace medical personnel in attendance and said issues missing from the workshop report.  Dan said the key missing information included radiation as well as microgravity concerns.  Dan then questioned the existence of a compelling rational for humans going to Mars.  This became a recurring discussion topic throughout today’s program.  Space settlement came up & so did a possible space race with China.  The subject of a rescue mission came up but there was a detailed rescue mission discussion near the end of the program in the second segment.  Dan was asked about the minimum crew size to operate an LLT program from Deimos or in orbit around Mars.  Several emails were sent in including one by Dr. Jurist addressing high acceleration upon return from Mars.  Dan then suggested the stepping stone approach, starting with cis-lunar space.  Doug sent in questions about heavy lift versus using already large commercial rockets.  Dan and Doug discussed this, then later in the second segment, Doug asked more questions on this topic.  For now they talked about going to Deimos with a Falcon Heavy.  Dan pointed out the need for many more launches and rendezvous missions as compared to one or two SLS type rocket launch.  He questioned if we can’t afford SLS launches, how do we afford even more launches and rendezvous missions.  Marshal emailed us wanting to know about the possibility of lava tube plans .  BJohn asked this guest about a possible Mars cycler & then we moved to the second segment.

In the second segment, I asked Dan what he thought the impact on space policy might be vis a vis the workshop being discussed on this program.  Don’t miss his reply.  Doug asked a question inquiring if for the same cost it would take to send humans to either Deimos or to the Martian surface, one could send many high-latency rovers to multiple locations far from each other to give the rovers many chances to discover evidence for life in different types of places?  This brought us several exchanges comparing LLT with HLT, heavy lift versus smaller rockets and more.  Doug and Dan has several exchanges during this segment, especially when the topic of rescue missions came up.  Ted in Boston asked about the rational for going to Mars, referenced the recent program with Dr. Zubrin, and the payoff or benefits for a human Mars mission.  Dan had much to say about this so don’t miss it.  John from Ft. Worth called to say we were not yet technically ready for Mars and we should use the stepping stone method and focus in cis-lunar development and exploration.  As an example, Dan & John talked about the need to know the actual gravity RX for humans. Dan said we should have a short arm centrifuge on the ISS helping to figure this out but that there was no policy to do that.  We turned to the topic of rescue and I told listeners what I found out about who pays for rescues when I did some quick and dirty research on this a few weeks ago.  The issue of rescue and how it might happen on a Mars mission or even in cis-lunar space came up with many listener emails including several by Doug putting forth various rescue scenarios.  For the most part, since we have no launch on demand, no rockets, pads or hardware sitting around ready to be used at a moments notice and we have to contend with launch windows, it does not seem feasible that a Mars rescue mission could be implemented, possibly not even a lunar rescue mission.  Doug suggested a scenario where multiple ships left for Mars at the same time and then if one got in trouble, the others could rescue the problem ship.  Dan talked about the physics and mass of what would be needed to do that. You decide if it might be feasible for such a rescue scenario to be implemented. Let us know your thoughts on the blog.  If the rescue party is already on Mars, rescue will be unlikely given the state of the art today.  Michael Listner suggested the absence of a realistic rescue plan may hinder the issuing of a launch license.  In his closing comments, Dan focused on the workshop critique saying that the sponsors would have been better served if participation had been opened up and had including human factors and aerospace medicine professionals.

We welcomed back Dr. Robert (Bob) Zubrin to discuss the upcoming Mars Society Convention in Washington, DC from August 13-16, 2015 (see www.marssociety.org/a/marssociety.org/www/conventions/18th-annual-international-mars-society-convention). During our 1 hour 45 minute program without a break, Dr. Zubrin not only told us about the upcoming Mars Society Convention for 2015, but talked about Human Spaceflight (HSF) to Mars by addressing many specific issues, concerns, and topics.  Starting off with the Convention, it is August 13-16, 2015 at the Catholic University of America in Washington, DC.  Special hotel prices are available at the Phoenix Park Hotel (see www.marssociety.org/conventions/18th-annual-international-mars-society-convention/hotel-and-transportation for reservation details).  Bob told us about the keynote speakers but also the special format this year for debates. Several topics will be debated including Moon vs. Mars, Mars One feasibility with the MIT team and Bas from Mars One, how best to achieve commercial space plus other topics.  Bob then started getting questions from listeners & myself on a wide variety of Mars HSF mission topics.  To start with, I asked Bob to comment on what several recent Space Show guests have said about our not being ready for HSF to Mars for a variety of reasons including radiation, other human factors, the costs, and the trip risk which would turn it into a survival mission and nothing more.  Before Bob responded to my specific question, he commented on the recent radiation paper, “How a trip to Mars would mess with your brain.”  Bob was very critical of this paper and spent time going through it and showing where he believed it to be bogus.  You can read Bob’s critique at www.marssociety.org/home/press/announcements/invalidclaimsmadeforwhathappenstoyourbrainonthewaytomarspublication.  Bob spent a good amount of time debunking the original article so don’t miss his comments.  Before moving on, I again asked Bob to respond specifically to what my guests had said as none of them mentioned the paper in question.  We had an interesting discussion on risk taking and the role of government as part of our discussion.  John in Florida called to ask about the concept of a nuclear explosion on Mars per Space Show guest Dr. John Brandenberg.  This led to questions about shortages of PU238, space policy & political leadership. Doug had questions about an Earth Return Mission and later he eventually called in to get a more precise answer to what he was asking.  We talked about one way missions, how best to explore Mars, and the responsible way to tackle the eventual settlement on Mars.  Emmet from NY called in to ask about Elon Musk Mars and NASA plans and why they seem to ignore going for artificial gravity.  Again, Bob had much to say about this issue which he said was different for Musk and NASA.  He felt Musk would address it as the challenge became more real for him.  As far as NASA goes, he said it was criminal to have avoided the issue for decades.  Don’t miss his comments.  Jackie emailed in a question about character in the book “The Martian,” wanting to know if crew were stranded on Mars could they actually do some of the things the character in the book did to survive.  You might be surprised by Bob’s answer.  Matt in Germany asked a question about Mars via the Moon, BJohn asked about the use of a cycler for Mars transportation & Kirk called to talk about an article he had read about fossil ice at Valles Marineris.  Kirk will post a comment about this on the blog after the show is archived.  Next up was the subject of terraforming Mars. Bob had much to say about this plus he offered a possible terraforming timeline. Doug then wanted to know if Bob was referring to paraterraforming when he mentioned the use of Domes on the Martian surface but Bob said no.  Tim called to talk about the radiation paper discussed earlier and mentioned a second experiment saying that antioxidants negated the radiation effects. Bob was not familiar with the second study but summarized his comments about the paper.

BJohn emailed in about rocket advances from the Saturn V for a Mars mission, we talked about what it would mean to use a Falcon Heavy for Mars missions, then Marshall called to inquire about sources of power on Mars, particularly nuclear and getting a large enough nuclear reactor to Mars.  Marshall and Bob talked about a Topaz like reactor.  Another question came up about using the Martian moons for the early human missions rather than Mars.  Bob explained why in his mind this was not a good idea.  He then compared the radiation dosage of long term ISS usage for ISS astronauts to the transit time and radiation dosage for a Martian crew.  Don’t miss what Bob had to say about this.  In Bob’s concluding comments, we focused on the upcoming convention but also on the importance NASA and a HSF mission to Mars in the context of the world today.  This is an important part of our program so don’t miss it.  In concluding, Bob said “It is time again for NASA to astound the world to show what free men can do.”  You will likely hear me use Bob’s closing statement on many future Space Show programs.

We welcomed Eric Berger to the program for a wide ranging discussion on US space policy, NASA, our space future, commercial space and more.  During the first segment of our 1 hour 37 minute show, Eric started the discussion by talking about his early interest in space, his contacting NASA as a child, getting back a great set of photos and other information and being hooked and excited about space ever since.  Some of the early topics in this segment included his surprise that we are not yet beyond low earth orbit with manned spaceflight, then he addressed why it is taking so long to go to Mars , why Mars is the next big step for humans and why going to Mars is so hard.  In his discussion of these topics, he referenced Elon Musk and the SpaceX Mars plans, even Mars One.  I asked Eric for his perspective on the NASA ARM mission which led to one of many discussion of NASA budget constraints and the idea that this or that project is all that can be done within the budget permitted by Congress.  Eric started getting lots of listener emails.  Jenkins wrote in saying that its not the budget that is the problems, the choices we make as a country regarding how we spend money that is the problem.  Eric then referenced the human spaceflight study released last year by the NRC regarding the likelihood that we will be living with tight NASA budgets for the foreseeable future.  Paul in New Mexico asked Eric about the impact of commercial space on policy and NASA.  Eric said it was an important impact so don’t miss his full statement.  Later in the segment, we talked about his seven part “Adrift” series last year and I asked him what his biggest surprise was in researching the articles for the series.  He said it was finding a shift in his view on SLS and that SLS could very well be an important part of our spaceflight future but that it needs to be funded to launch real programs.  He also said that maybe Falcon Heavy could do most of what SLS could do, especially in the Earth-Moon systems but that remains to be seen.  We then talked about the time it took to do various parts of Apollo compared to how much time it takes to do just about anything in space today.  Michael Listner called to talk about needing both NASA & commercial space and some realities involved in policy and space issues.  As the segment was ending, a Portland listener asked if competition with China might develop and force the US to spend more and do more in space.  Don’t miss Eric’s answer.

In the second segment, Eric was asked about space settlement being the goal and the purpose of our National Space Policy through a change in law per March Storm and other groups who are advocating this.  Eric was OK with space settlement but listen to his comments for the full context of his message.  He also said it was hard to figure out what to do with SLS but that some changes might be a full ten years out from today.  We talked about space technology advancements and then Gerald Driggers called in to say we had lots more work to do. For example, we talked about the need to fly a centrifuge in space to determine the gravity RX for humans.  The issue of the lack of space leadership came up from the White House down to the congress.  Many times our guest said it would take a change in leadership to get a change in space leadership but that just changing leadership does not mean the new leader(s) will care about or prioritize space.  Regarding commercial space, he went a bit deeper in this segment.  He said there was lots of commercial space activity but that NASA was still the center of it.  He made the case for the industry needing a broader base than just NASA.  I asked about a Europa mission and another listener asked he could articulate the Senator Ted Cruz view on space policy.  We talked timelines for humans to Mars and for a return to the Moon, he was asked if NASA should be eliminated in favor for a return to something like the old NACA, then Benny in Denver asked about the Texas spaceport facilities being developed for SpaceX and the Blue Origin facility.  As we neared the end of the program, Eric again stressed the difficulty in going to Mars, he looked back at our space history including Gemini 4, and he talked about the Obama policy from 2010 about not going back to the Moon though many in NASA do want to go back to the moon.  Bottom line was Mars around 2050.

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. John Jurist and Kobi Hudson to the program to discuss their recent experiences at the Orbital ATK 5 segment booster test in Utah and the ISS algae experiment Kobi and his teammates are working on at this time.  During the first segment of our 1 hour 58 minute discussion, John and Kobi talked about viewing the Orbital ATK 5 segment booster test this past March in Utah.  John has attended all the 5 segment booster tests but this was the first one for Kobi who is one of John’s students at Rocky Mountain College in Billings, MT.  Kobi described the test, what it looked like and how it felt from the viewing area, the networking opportunities he had with those attending the test including many executives from across our aerospace industry & NASA.  I asked John and Kobi if they sensed that the Orbital ATK team was aware of the controversy surrounding the final destination for the booster, SLS.  We talked about this for several minutes.  I think you will find what both John and Kobi had to say about this to be very interesting.  This discussion took us into an SLS discussion but from a slightly different perspective than our usual Space Show SLS discussions.  A listener asked our guests if either of them noticed a cultural difference in the test team given the Orbital and ATK merger.  Kobi was asked if the test and the experience inspired him to want to work in the aerospace field which it did.

 

In the second segment, Marshall called to inquire about the use of liquid rocket motors as compared to solids and wanted to know which type was more efficient. Both John and Marshall seemed to agree that it might depend on which type of propulsion system gets more launches and usage though the solids are far simpler.  As part of this discussion, the political dimensions of decision making were brought up as they play a role in the propulsion system and thus influence efficiencies.  Next, we turned to Kobi to explain to us the algae experiment he and others are working and which will fly to the ISS on the SpaceX 7 launch.  Behind this experiment is the goal of testing how well algae grows and how much carbon dioxide it consumes in a zero-gravity environment.  They want to see if it can influence the presence of oxygen in the spaceship.  The algae is grown in an agar solid media.  Kobi went into details on this experiment which I believe you will find of interest. When the team gets the data back from the 28 day test, Kobi will come back to the show to update us on what they found out.  Later in the segment, SLS John called in to follow up on our earlier SLS conversation and the proposed NASA ARM.  Several listener questions came in by email regarding both the issue of solids vs. liquids and the algae experiment.  Kobi also got a question or two about this work on the Firebird cubesat program.  He said it used a polar orbit , was then asked if cubesats could go to the Moon or elsewhere and he said probably but challenging. Doug called to talk closed loop life support and related issues.  The last question came from a high school senior asking Kobi about the need to attend a Tier One school and the consequences for going to a school not as well known and not as highly ranked.  All three of us, Kobi, myself, and John responded to this question saying about the same thing but in different words.  Both John and Kobi offered concluding comments you don’t want to miss.

We welcomed back Bob Zimmerman to the show for this 122 minute discussion on a wide range and variety of space news and project topics.  During the first segment, Bob spoke about Virgin Galactic and Launcher One delays, comparing it to the recent news that the AF will soon be testing a small satellite rail gun launcher, Super Strypi.  Bob suggested that the market might be passing VG by.  He also spoke to suborbital space both with VG and XCOR and true to form, was still skeptical about their potential success.  Some of Bob’s comments were challenged by listeners later in the show so stay tuned.  Next up Bob talked about the Russians opening up ISS tourism again in 2018 saying that the Russians believe the American private sector will be successful in transporting astronauts to and from the ISS by then so they will have available seats for tourists.  Don’t miss his comments on this subject.  He was asked about XCOR and he offered more comments on the company and suborbital space in general.  He then turned to the current round of ISS cargo bidding and compared it to the first round of cargo bidding a decade ago.  His comparison was most interesting and goes to the success being made by the developing commercial space sector.  Marshall was our first caller and talked about the next big planetary or HSF mission.  He also wanted Bob to discuss colonization.  Bob said he supported it but was realistic.  Bob then spoke about both the new Russian spaceport Vostochny and compared it to the progress being made by SpaceX and their new Brownsville spaceport.  He had much to say on this.  A listener emailed him to explain the space policy position of Sen. Ted Cruz.  That turned out to be quite a discussion, including Bob opining once again on SLS. Becky in Florida asked Bob about Mars One and Bob said it was a boondoggle.

 

In the second segment, Dr. Charles Lurio was our first caller.  Charles wanted to take Bob behind the woodshed on three points:  First, his comments on Kistler were wrong as the company was Rocketplane Kistler plus other details Bob missed. Second, he said Excalibur Almaz was not a fraud. This resulted in quite the exchange with Bob. The third area that upset Charles the most dealt with the comments Bob made about XCOR.  Charles was determined to correct the record on XCOR so again, don’t miss this exchange.  I asked Bob about the Indian space program and specifically their human spaceflight program.  Jerry from Florida emailed in additional info on Rocketplane Kistler.  SLS John called in to argue with Bob on his SLS comments.  I call their argument a draw with all participants including myself saying what we have been saying about SLS for years.  The subject of presidential leadership came up and Bob did his best to point out that it was probably a myth as far as space goes plus he cited supporting examples.  I pointed out that more than likely our next president, regardless of party, would have their hands full of solving major problems and I cited education as an example, referencing a recent survey I had seen showing just how poorly the US ranks worldwide in several educational areas.  This opened up a STEM discussion with Tim in Huntsville and Bob.  Jerry from Florida emailed in data showing that the Falcon Heavy would have more capability than SLS block one according to comments made by Ms. Shotwell at Satellite 2015.  This opened up another discussion on SLS, Falcon 9 and Falcon Heavy.  Here is an Aviation Week article that summarizes the comments Shotwell made at the event: http://aviationweek.com/blog/spacexs-gwynne-shotwell-talks-raptor-falcon-9-crs-2-satellite-internet-and-more.  Thanks to Jerry for providing us with this information and the article.   As the show was ending, Bob identified areas to watch for the second quarter and the balance of the year.

Welcome to our Audition and Co-host program.  During the first segment of our nearly 2 hour program, we did not get any audition calls from people contacting me to put themselves on The Space Show as a guest.  Toward the end of the program I took a call from Andrew regarding his being a co-host and one from Tim with an excellent suggestion for how to be on the program.  More about those calls when we get to the second segment.  For the first segment, Marshall called and talked about three sci-fi books he is writing plus I asked about his daughter who won a Space Show contest years ago and she got a tour of Loral and their satellite mfg. business.  Pooley called and talked about SpaceX, then he talked about the next several books being planned in the Microlaunchers series.

 

In the second segment, John in Ft. Worth called to talk about seeing the video on rocket reusability with Tori Bruno at Stanford. Mr. Bruno is the ULA CEO.  The better link to use when seeing this hour long video is http://youtu.be/iVFz67WCPIw.  John and I strongly recommend it.  Doug began emailing questions to John about depots and his previous calculations regarding the Falcon Heavy.  John admitted to an error in his previous analysis which he discussed that with Doug who was communicating via email.  Our next caller was Tim in Huntsville who suggested blogtalker.com for people who contact me wanting to be on the show.  Clearly such people do not follow my suggestion which is to call an Open Lines show or call when I do the auditions show but with blogtalker.com, they can actually make a short demo talk on their subject or topic for TSS and send me the URL.  Based on how well they do, the interest in the topic plus other factors, that would help me decide if a self-invited guest should be on the show.  Andrew was our last caller and he talked about himself being a co-host for topics dealing with astronomy, telescopes, engineering, machine tools, and more.  Doug communicated with Andrew by email to discuss the role of machining in the setting of an initial base (Moon or Mars) when in situ metals are accessed.  What all could be made?  I am working on this show with Andrew.

Welcome to our Open Lines discussion.  In the first segment of this 2 hour 2 minute program, I put forth some suggested topics and once again, I explained phone line issues for listeners regarding land lines, VoIP, compression, cordless phones, cell phones, digital phones, and even fiber lines.  Phone line issues remain the number one problem faced by The Space Show in delivering quality audio so once again I went over the requirements and the restraints based on our equipment and broadcasting equipment in general.  Several listeners did comment on the phone line issues via email.  John from Florida was the first caller and he talked about Ernst Stuhlinger and his work plus he requested Dr. Jeff Hoffman of MIT return as a guest to the show.  During our conversation, I mentioned ULA CEO Tory Bruno recent & his lecture at Stanford on the pros and cons of rocket reusability (www.youtube.com/watch?v=9DMb2yHh5CA).  Marshall was the next caller who talked about cell phones and the DSP computer in the phone. He also talked about SOHO and replacing old satellites with new ones. We talked about the cost of doing that and Marshall said he would gladly pay 5% more in taxes if he was guaranteed the money would be used for satellite replacement. I asked other callers if they would do that but nobody bothered to respond.  Marshall said we needed a satellite replacement program so jokingly, I suggested a Cash For Old Clunker Satellites modeled after the Cash for Clunkers car program several years ago.  Michael Listner called to talk about recent news articles suggesting the FAA was going to regulate lunar business.  He clarified this for us.  Emmet sent us a note suggesting Doug had a video on the net which had gone viral thus making Doug an internet star (www.youtube.com/watch?v=Rzy63276GEg).

In the second segment, Doug called the show & explained the video as a product of http://www.moonandback.com.  Doug talked about the planned SpaceX launch later in the day, the recovery of the first stage and the Falcon Heavy as part of his overall heavy lift discussion.  He also raised some questions about the Dawn Mission and its potential findings regarding Ceres.  Turbo pumps came up as did other issues with liquid rocket motors such as which fuel to use given my promoting the late April webinar addressing these and other rocket issues.  Ken from Dallas called to talk about Moon Day set for July 18, STEM, and he also mentioned Asteroid Day set for June 30.  As Ken is a sci fi movie authority, we talked some movies and TV shows.  John from Ft. Worth called and mentioned a movie and the satellite being launched by SpaceX nicknamed the Al Gore Satellite for Climate Change.  John briefly mentioned The Telegraph article showing how temperature data had been tampered with and calling it the biggest scandal ever (www.telegraph.co.uk/news/earth/environment/globalwarming/11395516/The-fiddling-with-temperature-data-is-the-biggest-science-scandal-ever.html).  John put forth some growth and population statistics as part of his argument against global warming.  Other subjects mentioned during this open lines by listener emails included why there was no live streaming of the first stage recovery attempt for the Falcon 9, why drones were not suitable for live streaming as they were with the Orion flight, plus many listeners emailed in about Cash for Clunkers & old satellites and the projects and work of Ernst Stuhlinger.

We welcomed back Dr. Paul Spudis for this 1 hour 52 minute discussion.  Note that we lost our phone connection with Dr. Spudis several times in the second segment.  I’ve removed the dead air and related time sequences but you will know when we lost the connection.  Each time we got Dr. Spudis back on the line we then started where we were cut off. No discussion comments were lost. I apologize for the inconvenience.  In Part One, I asked Dr. Spudis how he assessed a change in space policy that might include a return to the Moon as a result of the 2016 presidential elections.  Its an interesting space policy and historical discussion you don’t want to miss.  I then directed our discussion to the article Dr. Spudis wrote on his blog, http://www.spudislunarresources.com/blog/overthrowing-science, “Overthrowing Science.”  I urge you to read this article as we spent the balance of the first segment discussing his observations and perspectives and the order of scientific development and progress.  As we approached the end of the segment, I asked Paul how we could protect ourselves from the misleading and manipulative information often presented to us as science.  He offered a few suggestions including the need to be skeptical & to do at least basic due diligence on the subject from a variety of sources.

In the second segment, we turned our attention to an article,  http://www.theverge.com/2015/1/19/7560263/nasa-asteroid-redirect-mission-politcal-suicide, “Is NASA’s asteroid mission the agency’s political downfall?”  For about half of this segment, Paul went into detail on the ARM, why it was problematic at best, the constraints of such a mission, and more.  For those interested in the ARM, this is an exceptionally detailed discussion so don’t miss it.  Listeners then wanted to return to classic Dr. Spudis so the lunar questions started coming in via email.  Doug sent in a few emails asking about lunar volatiles, LCROSS, and the use of lunar solar panels for the energy of a lunar habitat.  Paul said initially the power would be solar but it would have to evolve to nuclear fission reactors.  BJohn wanted to know about the Lunar Resource Prospecting Rover plus he asked questions about lunar results from asteroid hits.  Tim asked about a reusable lunar shuttle and Dr. Kiehl asked lunar mining and crater questions.  Several other listeners sent emails comparing terrestrial geology to lunar and Martian geology, even asking if studying petroleum geology in grad school would be relevant to space planetary geology since the person wanted to work in the space industry.  Toward the end Paul was asked about the progress of cislunar development.  I asked our guest for closing comments so again, listen sharply as he had important things to say for us all.

We welcomed Tom Olson back to the show for his annual end of the year review show for the space year at hand, 2014.  During the first segment of our last program for 2014, I asked Tom for positive memorable events in 2014 .  Tom came well prepared for this question.  Do you have the same memorable events list or a different one?  Let us know on the blog.  As Tom was going through his list of memorable positive events and developments for 2014, we took some email questions about Blue Atlas, the Delta IV and human rating it, and of course ULA.  Another listener wanted to know what Tom thought of the idea of a prize for an on orbiting demo propellant depot and fuel transfer.  Toward the end of the first segment, Dr. Lurio called in and talked about fuel depots, markets for them, NASA and more. We also talked about Virgin Galactic and SpaceShip2 plus what may be forthcoming from the NTSB report when it becomes available.  Antares was also discussed before the break.

In the second segment, Jeff from Tucson called in about a possible Netscape Moment.  Tom did not think much of a Netscape Moment, instead he talked about the concept of space scalable.  I got in on the discussion as did others and this led us to our discussing reusability with SpaceX and would it be a game changer.  Later in the segment, more was said about the Delta IV, ULA, Atlas and even SLS.  For 2015, Tom talked about Bigelow Aerospace getting their modules up to the ISS.  He also talked about Dragon V2 and Falcon Heavy.  In addition, Tom mentioned Power Beaming test for SSP in space beaming power from point to point but in space.  Of course SLS and Orion came up. Tom is not supportive of it, Dr. Lurio called in who is not supportive of it and holding up the fort for it was our friend SLS John.  The latter part of the show was an ongoing give and take with Lurio, Tom and SLS John highly engaged in a back and forth but as you will hear, there were no winners.  Tom and I did a bit of reminiscing because we go back with one another for more than a decade.  We wished everyone a very Happy New Year and a great 2015.  And remember, “y’all come back for more in 2015!”
