We welcomed back to the show Dr. William (Bill) Farrand to discuss the Mars rovers, particularly Spirit and Opportunity which landed on Mars 12 years ago this month. In the first segment of our 1 hour 29 minute show, Dr. Farrand, a member of the Spirt/Opportunity team, updated us on the latest info coming back from Opportunity and he again told us what happened to Spirit to cause it to cease operating. Opportunity is very exciting and to see it still working 12 years later when it had an original life expectancy of about six months is quite amazing. We talked about the Opportunity team, the new information coming back from the rover, the science being done & the discoveries made by these two rovers over the past dozen years. Our guest took some questions about the move The Martian. While liking the movie, he said that the Martian landscape and terrain were not very realistic nor was the Pathfinder landing site. Later in the program, he was asked about Martian dust storms and he explained why the dust storm in the movie's opening scene was inaccurate. Don't miss his comments. Karen asked our guest to list off some of the top Opportunity discoveries which Dr. Farrand did do. He was asked about Opportunity detecting signs of past life but said no because it was not designed to identify organic materials. In his response, he focused on the upcoming Mars 2020 mission which would be better designed for organic and other life detection type experiments. As part of this discussion, Charlie in Atlanta asked what life detection instruments on a robotic space mission would consist of & wondered why such instruments were not on other Mars rovers. Before the segment ended, another series of questions fielded by our guest dealt with comparing Mars geology to Earth geology. Dr. Farrand talked about similarities between Mars and Earth geology but he also identified differences in rocks & geologic features. One of the major differences focused on the absence of tectonic plates and movements on Mars which are largely responsible for earthquakes here on the home planet. He talked about Mars faults and mars quakes but its nothing like what happens on Earth. Volcanic issues between Earth & Mars were also discussed with comparisons made between the two planets.In the second segment, BJohn asked about mission instrument selection differences based upon destinations such as our Moon, Mars, Martian moons, or an icy moon of Jupiter. Luis from Venezuela wanted our guest to compare Martian exploration by virtual reality as compared to astronauts on the ground. Read the rest of this summary @ www.thespaceshow.com.

John Batchelor and I welcomed Dr. Jens Biele to the show to discuss updates regarding the Rosetta Mission and the Philae Lander. First, regarding Philae, it appears to be dead but mission control is still keeping channels open & hoping for some sort of communication from it though as it moves further from the sun, communications are unlikely. Dr. Biele was also asked about exciting discoveries regarding Rosetta. One that stood out was learning that water on Comet 67P was not like water on Earth or elsewhere. Listen for details, at least to the extent the problem is understood today. He also said there were exceptional night images of the comet that had not yet been made public because of the challenges involved in explaining what is seen in the images. Can't wait to see them when they are made public! During our short Hotel Mars segment, our guest of honor mentioned organic molecules on 67P & he discussed amino acids wondering where they might have come from. You can email Mr. Batchelor or Dr. Jens Biele through me at drspace@thespaceshow.com.

During the first segment of our 1 hour 40 minute show, I made a few announcements and then we took the first call from Kim in Mexico. Kim made some very good suggestions for Space Show programs and guest including Hop's Blog which can be reached through www.clowder.net/hop and The Space Stack Exchange, https://space.stackexchange.com. Tim from Huntsville called next to talk about SLS and economic issues given I had read a news article on air about a CBO report on the increasing 2016 national deficit and the potential impact of rising interest rates on the debt, spending, and discretionary spending including NASA on into the future. Tim then sought financial information about the timing to take out some sort of financial loan in periods of rising interest rates, inflation, etc. As it turned it, I think he was seeking financial advice for himself so I cautioned him to value the advice to the degree he was paying for it. He got the point. In the second segment, John from Fremont called to talk about a suggestion he had sent me earlier regarding a space archaeologist who used imaging & infrared satellite data to find lost artifacts, cities, and such at different places on Earth. I will be contacting his suggestion with a Space Show invitation. Sarah from Boston emailed in asking for a series of shows doing a graduate level introduction to the subject of aerospace engineering. I then told listeners about an email I had received from Julian in Australia about the Australian Broadcasting Company four part space series that you may want to watch. Here is the URL for the series: www.abc.net.au/radionational/programs/showcase/features/outwardbound. John Hunt called in to suggest programming on VASIMIR and its founder, Franklin R. Chang Diaz. I said that I had made attempts to do VASIMIR programming and to have the CEO on the show but so far my efforts have not panned out. I mentioned a new attempt coming up and I hope that we can do this long awaited program/interview. John also said he wanted more physics, rocket engine, fuels, and cosmology programming. Tim called back to suggest a shown on the Rare Earth theory and identified the two main people involved suggesting I invite one of them or both to the show. I told him I would follow up on the suggestion.Please post comments/questions and your 2016 guest and program ideas in the comments section of this archived show.

This will help me bring better programming to the audience. We welcomed Chris Stone back to the program to discuss national security space issues. During the first segment of our 1 hour 50 minute program, Chris started out by giving us a working definition for national security space and some of the key issues associated with this segment of the space industry. We talked about passive defense and active defense, jamming, and physical attacks on space hardware, both of the reversible kind and the irreversible kind. I asked our guest if we considered an attack on our space assets as an act of war. Don't miss his reply to this question. Dr. Doug from S. California called for a somewhat lengthy discussion with Chris until we cut it short due to cell phone problems with Doug's line. Doug was questioning the value of the rapid replacement and quick launch to replace damaged space assets. List to what he had to say about this, why he was not supportive of it and hear what Chris said about Doug's ideas. Doug include satellite replacement, GPS, and the use of our SM3 missile defense system in his analysis. Its an interesting discussion so don't miss it. Also in this segment, Chris talked about first strike vulnerability and the idea brought up by Doug of giving up on space and diversifying capability to advanced ground and air systems if we lose the space component. Chris had much to say about this but was not advocating giving up on space as he said it was a key part of our defense and economic triad. In addition, it would signal our retreat which would open the door for even more aggressive adversarial problems. I asked Chris to comment on the progress of the Responsive Space programs to date. Chris talked about the potential Chinese Operationally Responsive Space Satellite knows as Koizhou (see www.parabolicarc.com/2013/10/03/china-launch-rocket), then I read an email from Jack about the effectiveness of our budget for space defense matters. Next in this segment, we had a discussion about vulnerability and risk regarding the different types of interference. Since Chris had been indicating that we were not that well prepared, Ben sent in a note asking for the justification for our leaders to not fully prepare this country for serious attacks on our space assets given the nature of today's economy and the role space place across all segments of our lives and commerce. I then read a note from Roger suggesting that the best deterrence was to make sure the adversary knew all hell would be unleashed on them for messing with our space assets.

This will help me bring better programming to the audience. We welcomed Steve Wolfe and James Cause to the program to discuss the business to business commercial space trade show, SpaceCom (see www.spacecomexpo.com). During the first segment of our 1 hour 27 minute program, James started out by describing the business to business commercial space trade show, SpaceCom, which will be an annual event in Houston. The event has NASA support, especially from JSC in Houston. We discussed the 2015 event with Steve on Space Show #2659 on Oct. 20 of last year so do listen to this program for event and expo details. James talked about the five industries being targeted to show them commercial space opportunities that they may not be considering or may not be aware of. These industries included the medical industry, manufacturing, the energy industry, communications and transportation industries. Near the end of this segment, our guests described programs available only in the Exhibit Hall. Listeners also sent in several email questions during this segment, including how they might be able to speak or participate in the expo event. In the second segment, we focused on technology transfer, the SpaceCom focus on LEO, suborbital flight, and tech transfer with listener questions asking if Mars was included in their focus as well as cislunar space development. One listener wanted to know about commercial opportunities for on orbit fuel depots and cryo technology development. Don't miss how our guests related that to their event's overall focus. Our guests frequently mentioned Satellite Applications Catapult, a UKSpace organization. Toward the end of our discussion, I asked both our guests how they differentiated SpaceCom from other commercial space programs and venues. Make sure you listen to their response to my question. Wayne got in the last question, asking them about time lines for commercial space development and noting the fact that the U.S. is not particularly good at long term investing. Our last topic dealt with turning point events for commercial space. Don't miss what our guests said plus what I said in addition to the events identified by our two guests. Both James and Steve left us with good closing comments and takeaway points.Please post your comments/questions in the comment section of this show's Space Show archive page.

Please note that audio and transition issues are a result of copying the John Batchelor broadcast & are not within my control as they originate in the Batchelor studio. John Batchelor and I welcomed Dr. Mark Brodwin to discuss the discovery and measurement of the massive young galaxy cluster IDCS 1428. Dr. Brodwin discussed the detailed analysis since 2012 by multiple ground and space telescopes. He told us how galaxy size is measured, plus he extrapolated the 10 billion light year away galaxy to what it would be like today in real time. We also talked about the size of this galaxy cluster being about equal to 500 trillion Earth suns! John and I asked Mark technical questions about the contributions of the different ground and space based telescopes, plus our guest helped us to understand the science associated with this discovery. Stay tuned for more as Dr. Brodwin will be a full Space Show program guest next month. You can email Mr. Batchelor or Dr. Brodwin through me at drspace@thespaceshow.com or through Dr. Brodwin's university website at the University of Missouri, Kansas City.

This will help me bring better programming to the audience. We welcomed Jim Muncy back to the show to discuss the newly passed U.S. commercial Space Launch Competitiveness Act of 2015 (see https://www.congress.gov/bill/114th-congress/house-bill/2262). During our one hour program, Mr. Muncy focused on Title II pertaining to resource extraction. This is commonly referred to as the asteroid mining part of the bill but actually the Act is far broader than just asteroid mining. Mr. Muncy went into quite a bit of detail in the discussion to explain this. He also pointed out why it does not conflict with the Outer Space Treaty, nor does it grant any property rights to the business or resource user. Jim talked about the balance of the bill, the fact that it was bipartisan, and the work that went into it by Congress and others to accomplish this legislation which Jim said was the most significant commercial space legislation since 2004, the Remote Sensing Act, and even the Launch Act of 1984. In the process of talking about the rest of the legislation, he mentioned an exemption by NASA from using commercial launchers to be able to use the SLS for specific SLS type missions. This led to an SLS/Orion discussion, appropriate payloads and missions for SLS, the cost involved, alternatives using fuel depots which would leave more money available for exploration missions. He also used the planned SLS upper stage as an example of the high costs and limited application which makes the hardware even more expensive. This part of our discussion sparked several listener emails including one from the UK and BJohn from Sweden. In the last ten minutes of the program, I asked our guest about the space policy positions of the presidential candidates of both parties. Jim said that both Senator Cruz and Senator Rubio played important parts in the commercial space law that we have been discussing. He said in the 2008 campaign, Hilary had made positive statements about commercial space. When specifically asked about Donald Trump, he told us what we knew already in that he has said we need to fix infrastructure first but Jim said he had no idea what he would do as president or if he might include space as part of an infrastructure improvement program. Jim's summary stressed the point that the bipartisan commercial space law shows what congress can do to better the nation by working together. This piece of legislation was a good role model for congress moving forward. Please post your comments/question in the comments section of this show's archive on The Space Show website.

This will help me bring better programming to the audience. We welcomed Dr. Louis Friedman back to the show, this time to discuss the NASA Asteroid Redirect Mission (ARM) and his new book, "Human Spaceflight: From Mars to the Stars." Our program used the one hour format so today's program summary used just one segment. We started our discussion with Dr. Friedman providing us with updates on the ARM & we learned that the ARM was alive and well. Dr. Friedman also said the ARM will actually enable getting back to the moon sooner. Don’t miss his explanation of this. Dr. Friedman talked about the role of SLS and Orion with ARM, planned robotic missions to the asteroid and an eventual human mission. Our ARM discussion was followed with our talking about his book for the rest of the show. Regarding his book, Dr. Friedman proposed the idea that humans will go to Mars but then stop. Beyond Mars, human exploration will be carried out via further advances in technology with robotics, nanotechnology, biotech plus other disciplines. He pointed out that after 50 years of human spaceflight, there have been far more technology advances than advances in the life support areas supporting human spaceflight. Listeners asked Dr. Friedman about other solar system destinations like Venus, Ceres, the Moon, and even moons of other planets. See if you agree with what Dr. Friedman said about these and other possible solar system destinations. We talked about timelines for humans to Mars, why Mars was and is so special for most people, and the need, if any, for space settlement, especially on the Moon and on Mars. BJohn wanted to know about going to Phobos, one of the two Martian moons. Jackie wanted to know about the ideas expressed by author Kim Stanley Robinson in his book "Aurora." Near the end of the program, I then asked Lou about the audience response to his ideas based on his speaking appearances about his book. Note what he said about the space enthusiast community as compared to a general audience. Before the show ended, another listener asked Lou what our TRL (technology readiness level) was for going to Mars today or in the near future. BJohn asked if space settlement would be undertaken by microbes! Do not miss Dr. Friedman's concluding comments.

This will help me bring better programming to the audience. Welcome to our first ever Cislunar Debate with guests John Strickland and Dr. Doug Plata. During the first segment of our 1 hour 55 minute discussion, it was clear to the listeners that while both Doug and John want to see cislunar development, they have different positions on how to accomplish the development. Doug also created an informal, totally unscientific survey listeners could use to "vote" the program or approach they liked the best, either Doug's or Johns. To vote of the categories identified in the survey, please go to (archive listeners get to vote too) www.lunarcots.com/survey. Due to time constraints, not all topics listed on the survey were discussed but should we do a second debate, the rest of the survey categories will be front and center in our discussion. You can comment on our new blog (part of TSS archives on the new website) about the survey, both approaches, and the discussion in general. Also note that the guests have posted comments and important links supporting their approach in the comments section of the blog for this show. We started the first segment with each guest providing us with both an introductory and opening position statement reflecting their cislunar approach, goals, and expected outcome from our debate. After the opening statements, both Doug and John put forth their objectives and rationales. For example, Doug wanted to accomplish the earliest possible settlement of the Moon and his approach reflects that objective by being simpler and less costly. John's objectives focused on sustainable development for both the Moon and Mars, included a larger, more complex, and costlier program. I did ask each candidate for their budget information for their approach plus the timeline for development. See what you think of this discussion, especially when I challenged both guests about our their costs considering our current economic climate. In addition, this segment included a discussion on public-private partnership development, public only development, high mass versus low mass mission planning, BLEO components, and large reusable boosters as compared to the use of expendables. Locations were important to this part of the discussion so much was said about Earth-Moon Lagrange points , the lunar surface, and orbiting fuel depots. John talked about expanding humans in the solar system, Mars as a backup planet, and having fully redundant rescue capabilities. Doug was looking to reduce costs to do much more and to do it faster. He spoke of using the Falcon Heavy and Vulcan, lunar propellant, and simpler infrastructure for life support. Read the rest of the summary at www.thespaceshow.com.
