We welcomed back to the show Dr. Jason Cassibry from the University of Alabama Huntsville to discuss nuclear propulsion of all kinds.  In our initial segment of this 1 hour 30 minute discussion, I first asked Dr. Cassibry about a fusion drive project as reported at www.youtube.com/watch?v=r-jlv1x3ov4.  Dr. Cassibry spoke about the work going on at the University of Washington which was mentioned in the fusion drive video above.  We then talked about transit times to and from Mars and the differences with chemical propulsion, nuclear thermal, and then fusion.  During this discussion, Jason also described the differences in nuclear thermal and nuclear electric propulsion.  A related issue we discussed dealt with the nuclear regulatory environment.  We talked about the nuclear climate, protests, and how best to overcome such protests.  Doug called asking about timelines and said it was moving at such a slow pace, for his projects that he thinks about, he dismisses nuclear propulsion, instead opting for analysis and mission planning using chemical rockets though many are not much further along than a Power Point at this point in time.  Doug also thought it might be easier to do nuclear propulsion by partnering with Russia as they might be easier on the regulatory environment than the U.S.  Our caller asked about ion propulsion and thrusters as well as thermal protection needs.

In the second segment, Jerry emailed about nuclear propulsion in other countries plus more about possible consumer protests.  Ben asked if we could substantially improve chemical rockets and I inquired as to why the recent nuclear program Prometheus was killed.  VASIMIR was next brought up for discussion.  I asked Jason about nuclear accidents in space or on Mars and would they be as destructive as nuclear reactor accidents here on Earth.  Jason provided a most interesting answer saying he thought nuclear reactors in space would be accident proof!  Christine in Dallas suggested we need a better story for more support for nuclear propulsion.  Don’t miss the reply offered by Dr. Cassibry. Near the end of our discussion, I asked our guest about suborbital propulsion.

We welcomed Dr. Wendell Mendell back to the show for this two hour discussion (no break) about his 50 years at NASA JSC, lunar bases, commercial space, return to the Moon, the value of the Moon, our space program, space advocacy, commercial space, and lots more.  Dr. Mendell came to work at JSC in 1963 &will be retiring at the end of this year, culminating 50 years at JSC.  During our discussion, Dr. Mendell used lots of stories from his NASA and lunar base work experience to illustrate issues with space policy, NASA, our Congress, and space advocacy, & advanced technology.  Listeners had lots of specific questions for Wendell about lunar bases, water on the Moon and its commercial exploitation, commercial lunar programs, and NASA having a lunar program which Dr. Mendell said it did not.  Dr. Mendell spoke to some of the NASA organizational issues, congressional micromanagement issues and problems, and the nation’s overall economic problems as a reason for not doing this or that in space.  He cited such economic problems as a rational excuse for not doing something meaningful in space in almost every year of his 50 years of NASA experience. The same for threatened, proposed, or even real NASA budget cuts.  Later in the segment when caller Doug called in with his lunar water and development ideas, Dr. Mendell pointed to conflicting LCROSS analysis as to water being on the Moon. Russian instruments do not say the same thing as the Los Alamos instruments and he said this was & still is a hotly debated topic in the lunar community.  As Doug continued talking about his plan, Dr. Mendell backed him up, took him step by step through the process of accomplishing his many goals. This turned out to be a very valuable instructional discussion that all of us can and should benefit from.  Make sure you hear how Wendell breaks down Doug’s points to show the complexities and challenges of each incremental step in what Doug was proposing.  Our guest even showed Doug where some of his steps needed commercial technogly which does not exist! Doug’s rocket of choice is the Falcon Heavy, a rocket which does not yet exist, nor does it have real numbers behind it.  Wendell used this discussion to distinguish true believers from investor and commercial analysts.  He then said when the believer is also able to bring his own money to the venture, things can get done and he cited SpaceX as an example.  Later Doug asked by email if NASA could help private companies develop cislunar transportation as they have helped private companies provide launch services to LEO/GEO. The simple answer was yes but make sure you hear Dr. Mendell’s complete answer to this question.  Another issue discussed was the needed timeline to do a human Moon mission. Wendell described the times of Apollo as compared to the times of NASA today.  We talked about the importance of a better and different NASA and RTM story and again, Dr. Mendell illustrated his points with stories from his past experience.  Spanning 50 years of history and experience was not easy to do in even a two hour Space Show program. As you listen to the program, you will hear many more subjects, stories, and issues discussed than stated in this summary.  In the end, I believe NASA, our nation, and the effort to develop space has been served incredibly well by Dr. Wendell Mendell and his creativity, his drive, his analysis, his commitment, and his work will be genuinely missed by all.  The Space Show wishes Wendell all the best for his coming retirement, gives him a hearty THANK YOU for his service, and we will remain in contact with him and hope to have him back with us at a future time.

We welcomed Robert Walker to the program for a 1 hour 28 minute discussion about his analysis, conclusions, and thoughts regarding humans putting colonies on Mars and elsewhere in the solar system.  You can read his articles at www.science20.com/robertinventor.  Robert has a YouTube channel at www.youtube/marsandspace.  I urge listeners to read his articles as they are thought provoking.  Though you might not agree with his conclusions, keep an open mind, his articles are very informative and what he has to say should be part of our human spaceflight to Mars discussion.  In other words, don’t dismiss or blow off what Robert and others are saying about the issues he brought to our attention today.  We started the discussion with his August 14th op-ed, “Ten Reasons Not To Live On Mars – Great Place to Explore.”  Rather than going through each of the ten items, for purposes of this summary and our discussion, we will talk about planetary protection and making sure humans do not contaminate any part of Mars for scientific exploration.  Robert referenced the UN as well as NASA and other nation’s Planetary Protection Policy against human contamination on Mars and the provisions in the Outer Space Treaty that impose this obligation on all signing countries.  Planetary Protection has been discussed before on several Space Show programs but Robert talked about it in the context of why humans to Mars missions will not be allowed and should not be undertaken.  He is much more supportive of orbiting missions such as Inspiration Mars or even going to Phobos and Deimos.  Most of our first segment is about this subject.  We also talked about sample return missions using the ISS or the Moon, exoplanets, lunar settlement, asteroid resources, and space exploration in general.

In the second segment, I opened asking him about his short article on the true color of a specifically discovered exoplanet which was cobalt blue as a result of a continuous rain of liquid glass.  Robert got several listener emails about planetary protection, Elon Musk and his plans to settle Mars, ways to avoid contamination, and more.  He even got a question or two asking why in the literature ETs that have come to other in the stories (maybe), etc. don’t seem to have a regard for avoiding contaminating Earth.  This was a fun discussion. Another listener asked him a question about his musical and math background and using music to communicate with ET in sci fi movies, wondering if there was any science in fact to the idea of musical communication.  Another fun discussion.  Jody asked about going to a dry part of Mars with humans to avoid contamination.  Don’t miss Robert’s reply to this scenario.  Robert also spoke about teleportation, saying it was key to space exploration.

We welcomed Dr. Bruce Damer back to the show to discuss his 3D real time simulations, the human NEO mission study & design project, planetary protection, astronaut safety and much more.  Here are the websites Bruce mentioned on air:  www.damer.com, www.levityzone.com, and www.digitalspace.com.  In addition, later in our discussion Bruce also talked about a Dave Brody YouTube video that was relevant to our discussion.  You can find this video at www.youtube.com/watch?v=UAm9escDxu0.   In the first segment of our 1 hour 31 minute discussion, Dr. Damer talked about the renewed interest in asteroid projects within NASA and by others, especially after the Russian event a few months ago.  Dr. Damer had lots to say about a recent meeting he attended at AMES, budgets, and the renewed interest in the subject.  Listeners started asking him questions early on, including questions about docking with an asteroid with little or no gravity, the use of aerogel to collect micrometeorite particles, plus the recently announced commercial asteroid missions being planned.  Robots versus humans came up many times, Curt asked about the use of the ISS, prioritizing budgets, lunar basis, etc.  Doug called in regarding the incremental approach Dr. Damer had mentioned or as referred to in our discussion, stepping stones.

In the second segment, we talked about the designs on www.digitalspace.com and the Brody YouTube video per the above URL.  Also discussed was planetary protection with the use of the gravity tractor. We talked about needed lead times to interfere with a potentially dangerous NEO that might be headed for Earth,  then more questions came in about a lunar base and what Bruce thought to be more important, the lunar base, Mars, or the NEO mission.  Doug called in to discuss and challenge some of the mission planning ideas Bruce put forth, especially around trial and error, R&D, incremental development and long time lines.  Near the end, we talked about human spaceflight safety & the ideas put forth by Rand Simberg & others that we needed to take more risks, not make safety the extreme priority.  Bruce had many relevant & important comments on this subject.  Final comments focused on 50-100 years in th future with asteroid & other capabilities but only if we keep moving forward today.

Guest:  Jerry L. Ross.  Topics:  “Spacewalker: My Journey In Space And Faith as NASA’s Record-Setting Frequent Flyer,” HSF safety, NASA & space policy.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.

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 retired astronaut Jerry L. Ross to our program to discuss his new book, “Spacewalker: My Journey In Space And Faith as NASA’s Record-Setting Frequent Flyer,” space policy and leadership, HSF safety, and much more.  If you buy his book which I recommend, use this Amazon link as Amazon will make a donation to The Space Show/One Giant Leap Foundation: www.amazon.com/Spacewalker-Journey-Space-Record-Setting-Frequent/dp/1557536317/ref=onegiantlea20.  Please visit Jerry’s website for more information, www.jerrylross.com.  During the first segment of our 90 minute program, Mr. Ross spoke about the Space Shuttle & retirement, Constellation, returning to the Moon, going BLEO, the ISS, and his test flights on the B1 bomber.  This led us to talking about the safety test program used by NASA, the B1, and the private spaceships.  I asked if NASA was overkill in this area and if the privates would be able to engage in comprehensive flight safety testing with programs radically different from those NASA has used. You do not want to miss this discussion, especially when I asked about the complexities of the B1 as compared to a spaceship.  We talked about SLS, Orion, & Inspiration Mars which Jerry supports.  In response to an email from Becky, we talked about the NASA astronauts, the fact that there are more astronauts than flight opportunities, and the current situation for NASA astronauts.  Our guest mentioned two year training missions and when I inquired about that time period, we learned that it included learning Russian, training with ESA, Japanese, Canadian, and Russian hardware and more.  Jerry was asked if he rode on a Soyuz. He said no but was in a Soyuz and talked about his going on board MIR.

In our second segment, we started out asking him about faith which is part of the subtitle of his book.  Here again our guest had much to say so listen carefully to this discussion.  As Jerry was part of the team that recovered debris from the Columbia accident, I asked him about it. He told us about his experience in learning about the disaster, crew families and more.  This is a first hand accounting of getting the news and working with the families and the people involved in finding the debris.  Another topic discussed was on orbit construction, mainly with the private companies.  Jerry talked about this at length given his work in establishing how to do it for the ISS and actually doing multiple missions making and assembling parts in space.  We also talked about gender differences in these space walks.  Toward the end of our discussion, space leadership came up as did missions and goals.  The shuttle thermal tiles were discussed and he referenced tile damage on his Atlantis flight which was the third flight after Challenger.  This was an amazing story and luck was really shining on the Atlantis crew.

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. David Lawrence to the program to discuss the planet Mercury & the NASA Messenger Mission’s latest finding.  For more information, visit the Messenger websites, http://www.nasa.gov/mission_pages/messenger/main/index.html & http://messenger.jhuapl.edu.  We started our discussion by describing the Mercury & the Messenger mission.  For example, it took over six years to get to Mercury because of the difficulty in slowing the spacecraft down given the close proximity to the sun.  Dr. Lawrence explained this process to us & the Venus, Mercury, & Earth flyby program used by the spacecraft to orbit around Mercury.  We talked about the spacecraft health, the instruments on board & the problem with the gamma ray spectrometer which worked for about 9,000 hours on an expected life of 8,000 hours.  However, data from this instrument is still being analyzed & will be for some time to come.  Other instruments on Messenger are fine & the spacecraft has a life expectancy to 2015.  Our guest explained mission nominal life & the process for mission extensions with additional NASA funding. We talked about funding issues for Messenger & other planetary missions in light of NASA budget issues & the overall U.S. economy.  Dr. Lawrence told us how the missions compete for extension & additional funding, plus the requirements they must meet to be extended.  Listeners wanted to know about the application of Messenger & Mercury science to Earth & other solar system missions, our Moon, a NEO, even Mars.  Other listeners wanted to know Mercury’s distances from the sun & Earth, as well as more about possible tectonic activity on Mercury.  We discussed basic chemical elements found on Mercury as well as volatile elements.

In our second segment, Dr. Lawrence was asked to identify the biggest surprise so far which he said had to do with the composition of the planet & volatile elements with high concentrations of sulfur & sodium, among others.  A listener asked about Mercury radiation levels & another listener wanted to know how Mercury crater’s got their names.  Dr. Lawrence then took us through the crater naming process which you can also read about on the Messenger websites.  We talked about Messenger’s discovery of Hollows (see, http://science.nasa.gov/science-news/science-at-nasa/2011/24oct_sleepyhollows).  One listener asked our guest how one gets on a science team like Messenger. Dr. Lawrence explained the paths to joining these teams.  Mercury’s high density came up & our guest talked about most all of the iron on the planet being concentrated in its core.  We also talked about data analysis, archives, embargos, & availability.  Our guest directed us to the NASA Planetary Portal System for more information.  Near the end, we talked about the NASA Discovery Program & other successful Discovery missions including Dawn.

Please post your comments/questions on The Space Show blog.  You can email Dr. Lawrence through me or the APL Messenger website.

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 Jim Keravala to the program to talk with us about the Cislunar development plans for Shackleton Energy.  To learn more, visit their website at www.shackletonenergy.com. Jim started our discussion with an overview of Shackleton Energy and their Cislunar development plan.  As you will hear throughout our discussion, the plan involves the propellant depots near the ISS and in other locations, water ice development at the lunar north and south pole, the use of insitu resources and eventually Shackleton industrial astronauts.  Our guest spent most of the first segment describing the plan, the various stages of development, the use of robotic technology leading up to human spaceflight and benefit sharing ideas.  He talked about being able to solve or at least significantly contribute to solutions to our global energy usage problems which he said would be around 30 terawatt hours(TWh).  He talked about the viability of SSP at that point based on the cislunar Shackleton Energy development program. Jim also mentioned the risk of reaching the Kessler limits regarding space debris.  Ben sent in an email asking Jim for his thoughts on benefit sharing, a subject put forth on The Space Show by recent guest Dr. Edythe Weeks.  Jim was supportive of benefit sharing through technology exchanges and transfers as well as in helping under developed nations build an industry to allow them to compete and have a presence in the expanding space industry.  He cited his work with Surrey Satellite Company and their African space development program as an example, plus he talked about sharing to make sure everyone benefitted from space development which could significantly improve life in these countries.  We talked about government corruption problems and ITAR as issues that might get in the way of benefit sharing, but Jim was steadfast in the need to reach out to third world countries to engage them in space development for the commercial and industrial benefits.
     In our second segment, Doug called to ask about transitioning from telerobotic missions to human missions.  Here, Jim did a comprehensive explanation of the different phases of their development plan leading up to industrial astronauts in cislunar space. He talked about trades with humans based at EML1 as compared to the lunar surface regarding repair and maintenance missions of lunar surface hardware.  Charles wanted to know about their choice of launch vehicles.  Jim also got questions about their timeline and capital acquisition plans.  Randy wanted to know if they would be able to meet the 2020 timeline referenced in their website video.  Near the end, Jim got questions about the requirements for becoming an industrial astronaut.  In summary, Jim talked about their ambitious project, TRLs, and the importance of the project from many different perspectives.
